The residential zones implement the single-family and higher density residential goals and policies and land use plan map designations of the comprehensive plan. They are intended to preserve land for housing and to provide housing opportunities for individual households. The zones are distinguished by the uses allowed and the intensity of development allowed. The differences in the zoning categories reflect the diversity of residential areas in the city. The limits on the intensity of uses and the development standards promote the desired character for the residential area. The standards are intended to provide certainty to property owners, developers and neighbors of what is allowed in the various categories. (Ord. 2852 § 10 (Exh. A), 2011).

The full names, short names and map symbols of the single-family and higher density residential zones are listed below:

(Ord. 2852 § 10 (Exh. A), 2011).

(1) Neighborhood Residential 4.5 (NR-4.5). The NR-4.5 zone is a medium density single-family residential zone. It allows single-family residences, middle housing, and townhomes. The base density is 4.5 dwelling units or lots per acre. The major type of new development will be detached single-family residences, with middle housing and townhomes also permitted.

(2) Neighborhood Residential 6.5 (NR-6.5). The NR-6.5 zone is a high density single-family residential zone. It allows single-family residences, middle housing, and townhomes. The base density is 6.5 units or lots per acre. The major type of new development will be detached single-family residences, with middle housing and townhomes also permitted.

(3) Low Density Multiple-Family (R-12). The R-12 zone is a low density multiple-family residential zone. The major types of new housing development will be detached single-family residences, middle housing, townhouses, apartments and condominiums. The density is 12 units per acre; the maximum is limited to 18 units per acre.

(4) Medium Density Multiple-Family (R-18). The R-18 zone is a medium density multiple-family residential zone. The major types of new housing development will be detached single-family residences, middle housing, townhouses, apartments and condominiums. The density is 18 units per acre; the maximum is limited to 27 units per acre.

(5) High Density Multiple-Family (R-28). The R-28 zone is a high density multiple-family residential zone.

The density is six units per acre for detached single-family and 10 units per acre for attached multiple-family; the maximum is limited to 18 units per acre.

(7) Residential Mobile Home Park (R-MHP). The R-MHP zone preserves high density, affordable detached single-family and senior housing. This zone is assigned to existing mobile home parks within residential zones which contain rental pads, as opposed to fee simple owned lots, and as such are more susceptible to future development. (Ord. 3366 § 39 (Exh. MM), 2025; Ord. 3352 § 42 (Exh. MM), 2025; Ord. 2852 § 10 (Exh. A), 2011).

The standards in this chapter state the allowed uses and development standards for the base zones. Sites with overlay zones, subarea or master plans are subject to additional standards. The official zoning maps indicate which sites are subject to these additional standards. (Ord. 2852 § 10 (Exh. A), 2011).

(1) Purpose. The purpose of this section is to allow for adaptive reuse of nonresidential buildings in residential zones that are functionally obsolete in order to improve the economic feasibility of a property by considering uses that are not otherwise permitted, but which, if properly designed and managed, would not create unacceptable impacts on surrounding properties or the immediate vicinity in general. This process differs from the unlisted use process listed in MMC 22A.010.070 in that uses that are not specifically authorized in the residential zone may be considered using the process described herein.

(2) Procedures. Any request for adaptive reuse of nonresidential buildings shall be reviewed as a conditional use.

(3) Circumstances. The city may allow a use in a residential zone that is not specifically allowed in that zone if it is necessary to encourage adaptive reuse of a building under the following circumstances:

(a) It is unlikely that the primary building on the subject property could be preserved if only uses permitted in the underlying zone were allowed.

(b) Allowing a different use would enhance the character of the building and immediate vicinity.

(c) The use would not have a detrimental effect upon surrounding properties or the immediate vicinity.

(4) Uses That May Be Allowed. The following uses may be considered for adaptive reuse of an existing building in a residential zone; provided, that where a use listed below is allowed as either a permitted or conditional use in MMC 22C.010.060, it shall be reviewed in accordance with said section:

(a) Dwelling units. Density based on underlying zoning;

(b) Assisted living facilities;

(c) Libraries;

(d) Museums and art galleries;

(e) Social service facilities;

(f) Public services;

(g) Artist studios;

(h) Music venues;

(i) Cafes and bistros;

(j) Live-work units;

(k) Bed and breakfast inn;

(l) Other uses not listed above if determined through the review process to be compatible with surrounding properties and the immediate vicinity.

(5) Review Criteria. The following criteria shall be used as the basis for determining compatibility with surrounding uses and approving, denying, or conditionally approving a request to allow the adaptive reuse of a nonresidential building in a residential zone:

(a) The adaptive reuse would promote or aid in the preservation or rehabilitation of the primary building.

(b) No significant impacts to public safety.

(c) Compliance with noise, building and fire codes.

(d) Hours of the day of proposed use or activity are compatible with surrounding uses.

(e) Proposed management and operational procedures to minimize and mitigate potential impacts.

(f) Other factors not specified herein that would create a conflict with the surrounding uses, or uses that are permitted in the zone.

(g) Expansions to the primary building shall not exceed 10 percent of the existing footprint or 500 square feet, whichever is greater, and will not detrimentally affect the outside character of the building. Expansions shall comply with the bulk and dimensional standards of the underlying zone.

(6) Actions Authorized.

(a) Approval. The city may approve a proposal that is found to be compatible with surrounding land uses.

(b) Denial. Any proposal that would be incompatible with or adversely affect properties in the immediate vicinity shall be denied.

(c) Revocation. The city shall retain the right to revoke an approval issued under this section that fails to comply with any conditions of said approval, or which operates in a manner inconsistent with representations made in the application. (Ord. 3366 § 42 (Exh. PP), 2025; Ord. 3352 § 45 (Exh. PP), 2025; Ord. 3207 § 5, 2022).

(1) Interpretation of Table.

(a) Subsection (2) of this section contains general density and dimension standards for the various zones and limitations specific to a particular zone(s). Additional rules and exceptions, and methodology, are set forth in MMC 22C.010.100 through 22C.010.250.

(b) The density and dimension table is arranged in a matrix format and is delineated into different dimensional categories.

(c) Development standards are listed down the left side of the table, and the zones are listed at the top. The matrix cells contain the minimum dimensional requirements of the zone. The parenthetical numbers in the matrix identify specific requirements applicable either to a specific use or zone set forth in MMC 22C.010.090. A blank box indicates that there are no specific requirements. If more than one standard appears in a cell, each standard will be subject to any applicable parenthetical footnote following the standard.

(2) General Densities and Dimension Standards.

(Ord. 3366 § 43 (Exh. QQ), 2025; Ord. 3352 § 46 (Exh. QQ), 2025; Ord. 3057 § 4, 2017; Ord. 2852 § 10 (Exh. A), 2011).

(1) Base Density. The base density is the standard density allowed in the zone and indicates the number of dwelling units or lots allowed per net acre.

(2) Maximum Density. The maximum density for each zone indicates the maximum number of dwelling units or lots allowed per net acre.

(a) The maximum density for the R-12, R-18, R-28 and WR-R-6-18 zones may only be achieved through the application of residential density incentive provisions outlined in Chapter 22C.090 MMC.

(b) The maximum density for the NR-4.5 and NR-6.5 zones is limited to planned residential developments developed pursuant to Chapter 22G.080 MMC and requires the application of residential density incentive provisions outlined in Chapter 22C.090 MMC.

(3) Exceptions. The following exceptions to the base density and maximum density provisions apply:

(a) Accessory Dwelling Units.

(i) A maximum of two accessory dwelling units are allowed per lot accessory to a detached single-family residence pursuant to MMC 22C.185.020, Table 1.

(b) Middle housing, as defined in MMC 22A.020.140, is allowed for all lots zoned predominantly for residential use as follows:

(i) Middle housing is subject to the maximum number of lots allowed for the zone; however, it is allowed a greater unit density as shown in the table below:

(ii) The unit density allowance applies to the parent lot prior to any unit lot subdivision.

(iii) Multiple middle housing structures may be allowed per lot up to the allowed unit density specified in the table above. For example, two duplexes (four total dwelling units) may be allowed per lot that either is located within one-quarter mile of a major transit stop or when one affordable housing unit is provided.

(iv) Accessory dwelling units apply to the total allowed unit density for the lot (i.e., are not allowed in addition to the specified units per lot).

(v) The unit density detailed in this table for proximity to transit and provision of affordable housing are discrete options. If a lot has both proximity to transit and provides affordable housing, the total unit density remains at four unless otherwise allowed by code.

(vi) Unless zoning permitting higher densities or intensities applies.

(vii) Currently the city of Marysville is a Tier 2 city pursuant to RCW 36.70A.635(1)(a). The city will need to comply with the Tier 1 standards in RCW 36.70A.635(1)(b) one year after the city’s comprehensive plan implementation progress report is due pursuant to RCW 36.70A.130(9)(a).

(c) The absence of water or sewer service may limit redevelopment or additional development until such time sewer infrastructure improvements are made.

(4) Reserved.

(5) Base Height.

(a) Height limits may be increased when portions of the structure which exceed the base height limit provide one additional foot of street and interior setback beyond the required setback for each foot above the base height limit; provided, that the maximum height may not exceed 60 feet.

(b) Multiple-family developments, located outside of the downtown neighborhood, abutting or adjacent to areas zoned as single-family, or areas identified in the comprehensive plan as single-family, may have no more floors than the adjacent single-family dwellings, when single-family is the predominant adjacent land use.

(6) Applies to Each Individual Lot.

(a) The 50 percent impervious surface coverage applies to complete land use applications for subdivisions submitted on or after the effective date of Ordinance 3057, adopted May 8, 2017; provided, however, in the case of approved development applications that have not yet started construction, an applicant may file for a minor revision to the approved land use application in accordance with MMC 22G.010.260.

(b) Building coverage and impervious surface area standards for:

(b) The average setback of the NR-4.5 and NR-6.5 zoned and platted single-family detached dwelling units from the common property line separating said dwelling units from the adjacent townhouse or apartment development, provided the required setback applied to said development shall not exceed 60 feet. The setback shall be measured from said property line to the closest point of each single-family detached dwelling unit, excluding projections allowed per MMC 22C.010.210 and accessory structures existing at the time the townhouse or apartment development receives approval by the city.

(11) Townhouse setbacks are reduced to zero on an interior side yard setback where the units have a common wall for zero lot line developments.

(12) Townhouse setbacks are reduced to five feet on side yard setbacks provided the buildings meet a 10-foot separation between structures.

(13) Single-family detached units and middle housing on individual lots within the R-12 through R-28 and WR-R-6-18 zones may utilize the base density for the underlying zone; provided, that lots shall be subject to a 50 percent building coverage, 65 percent impervious coverage, 4,000-square-foot minimum lot size, 40-foot lot width, and the setback requirements of the neighborhood residential 6.5 (NR-6.5) zone.

Approval is at the discretion of the community development director.

(18) In order to accommodate a daylight basement or tuck-under garage, the base height for the principal dwelling may be increased to 35 feet on lots with a 10 percent or greater slope within the building’s footprint.

(19) The minimum densities are the minimum number of dwelling units which must be constructed per net acre. The director may waive the minimum density requirement for sites with unique size, shape, topography, location, critical areas encumbrance, distance from utilities, or other feature(s) that precludes the minimum density being achieved. In addition, an applicant intending to construct only one residence may also receive relief from the minimum density requirements; provided, that the residence is sited in such a manner that future development is not precluded. A written justification must be provided by the applicant for all requests for relief from minimum density requirements and is subject to director approval. (Ord. 3366 § 44 (Exh. RR), 2025; Ord. 3352 § 47 (Exh. RR), 2025; Ord. 3057 § 5, 2017; Ord. 3054 § 9, 2017; Ord. 2852 § 10 (Exh. A), 2011).

The following provisions shall be used to determine compliance with this title:

(1) Street setbacks shall be measured from the existing edge of a street right-of-way or temporary turnaround or, in the case of a substandard street, the setbacks shall be measured from the edge of the ultimate right-of-way section planned for the street, except as provided by MMC 22C.010.200;

(a) Step 1: Calculate the net acreage by using the “net project area” definition in MMC 22A.020.150, “N” definitions.

(b) Step 2: Multiply the net acreage by the units or lots per acre allowed by the zone as set forth in MMC 22C.010.080.

(c) Step 3: When calculations result in a fraction, the fraction shall be rounded to the nearest whole number as follows:

(i) Fractions of 0.50 or above shall be rounded up; and

(ii) Fractions below 0.50 shall be rounded down.

(2) Middle housing is subject to the maximum number of lots allowed for the zone set forth in MMC 22C.010.080; however, it is allowed a greater unit density as specified in the table 22C.010.090(3)(b)(i).

(3) The provisions in subsection (1) of this section apply to lots which will be subdivided. Existing, legal lots under MMC 22C.010.140 and reasonable use lots under MMC 22E.010.410 are not subject to the calculation above. (Ord. 3366 § 45 (Exh. SS), 2025; Ord. 3352 § 48 (Exh. SS), 2025; Ord. 2852 § 10 (Exh. A), 2011).

(2) Interpreting and Applying the Design Standards.

(a) These standards capture the community visions and values as reflected in the comprehensive plan’s neighborhood planning areas. The city’s community development director (hereinafter referred to as director) retains full authority to determine whether a proposal meets these standards. The director is authorized to promulgate guidelines, graphic representations, and examples of designs and methods of construction that do or do not satisfy the intent of these standards.

(b) Within these standards, certain words are used to indicate the relative importance and priority the city places upon a particular standard.

(i) The words “shall,” “must,” and “is/are required” mean that the development proposal must comply with the standard unless the director finds that:

(A) The standard is not applicable in the particular instance; or

(B) The development proposal meets the intent of the standards in some other manner.

(ii) The word “should” means that the development proposal will comply with the standard unless the director finds that:

(A) The standard is not applicable in the particular instance;

(B) The development proposal meets the intent of the standards in some other manner; or

(C) There is convincing evidence that applying the standard would not be in the public interest.

(iii) The words “is/are encouraged,” “can,” “consider,” “help,” and “allow” mean that the action or characteristic is allowed and will usually be viewed as a positive element in the city’s review.

(c) The project proponent may submit proposals that he/she feels meet the intent of the standards but not necessarily the specifics of one or more standards. In this case, the director will determine if the intent of the standard has been met. (Ord. 3366 § 55 (Exh. CCC), 2025; Ord. 3352 § 58 (Exh. CCC), 2025; Ord. 3245 § 1 (Exh.

(i) Be located in a contiguous area and abut the cottage it serves;

(ii) Be oriented towards the common open space as much as possible;

(iii) Have no horizontal dimension less than 10 feet; and

(iv) A fence or hedge not to exceed three and one-half feet high may separate private open space from common open space.

(f) Common open space shall:

(i) Be provided in a contiguous area to the extent feasible;

(ii) Be allocated so that at least 50 percent of the common open space for a grouping of cottages is located centrally among the grouping of cottages; and

(iii) Have no horizontal dimension less than 15 feet.

(9) Building Design Standards – Including Garages/Parking Structures. The purpose of the design standards is to: encourage variety and visual interest in new residential development in a manner that is compatible with the neighborhood character; ensure the scale of the cottages is proportional to their lot and parcel size, provide landscaping between new and existing development to buffer and provide a transition, enhance the building and site appearance, and maintain the quality of the neighborhood.

(a) Inviting Facade. Each cottage unit shall have an inviting facade for any facades abutting common open space areas, public rights-of-way, and private roads or accesses serving the cottage housing development. If a cottage unit abuts more than one public right-of-way or private road or access, the director shall determine which access the inviting facade shall be oriented towards.

(b) Building Character Proportionality and Massing. Size and height reductions of cottage housing, design techniques and perimeter buffer landscaping shall be used to promote compatibility with the surrounding neighborhood and proportionality and massing of new cottage development adjacent to existing single-family neighborhoods.

(c) Variety in Buildings and Visual Interest With Consistency in Architectural Style. The building designs and layout shall prevent the repetitive use of the same combination of building features, building layout, and site design elements within any cottage development, grouping of cottages, and adjacent dwellings.

(i) Varied and Interesting Rooflines. Varied and interesting rooflines must be provided which include use of varied pitched roof styles, gables, or dormers. Roof breaks or step-downs are encouraged and can be used to reduce required setbacks adjacent to parcel boundaries.

(ii) Separation of Identical Buildings and Elevations. Units of identical elevation types must be separated by at least two different elevations. This will result in at least three different building elevation plans per cluster. No two adjacent structures shall be built with the same building elevation (reverse elevations do not count as a different building elevation), facade materials, or colors.

(iii) Different Roof, Window Design and Entries. Provide differing roof forms, gables or dormers. Roof overhangs a minimum of six inches are required. Different window design, entry treatments and base treatments shall be utilized to help achieve variety.

(iv) Corner Lot Cottages. Cottages on corner lots shall be architecturally designed to provide modulation and detail on both frontages. Examples of modulation include use of bay windows, wrapped porches, and dormers.

(v) Open and Closed Cottages Along Private Side Yards. Private side yards are an important element in cottage development. The side yard is typically designated to a particular cottage (like zero lot line homes) and this cottage should be open to the side yard using doors, windows or a wrapped porch. The adjacent cottage having a closed side and window placement is an essential part of the design to achieve this relationship.

(d) Variety in Building Design. Provide variety and visual interest by using a combination of building elements, features and treatments in cottages as well as garages. Structures must include building articulation, change in materials or textures, windows, or other architectural features. A minimum of at least one side articulation or roof break shall occur for side elevations facing public streets or common open spaces or walkways to the common open spaces. No blank walls are allowed. The following building elements, features, and treatments that provide variety and visual interest shall be used in combination to create variety in building design, but are not limited to:

(i) Variation in building type and plans.

(ii) Variation in layout and orientation.

(iii) Variation in building materials, mixture and texture.

(A) Vertical Changes. Changes in materials in a vertical wall shall occur at an internal corner or a logical transition such as aligning with a window edge or chimney.

(B) Horizontal Changes. Transition in materials on a wall surface, such as shingle or lap siding, shall be required to have a material separation, such as a trim band board.

(C) Acceptable Exterior Wall Material. Wood, cement fiberboard, stucco, standard sized brick and stone may be used. Simulated stone, wood, or brick may be used to detail homes.

(D) Trim. Trim may be wood, cement fiberboard, stucco, or stone materials. Trim is required around all doors and windows. The trim must be three and one-half inches minimum and be used on all elevations.

(iv) Building modulation.

(v) Building intervals and articulation.

(vi) Varying roof shapes, pitches and gables.

(vii) Varied roof heights and roof breaks or roof extensions.

(viii) Dormers.

(ix) Window trim and mullions.

(x) Bay windows or bump outs.

(xi) Entry enhancement.

(xii) Porches and patios. (Porches with railings preferred.)

(xiii) Use of varied siding, trim and base colors.

(xiv) At a minimum use bottom and top material treatment and if recommended use tripartite architecture.

(xv) Chimney or tower.

(xvi) Trellis.

(xvii) Belly bands, brackets/braces.

(xviii) Other building elements and the combined use of the above shall be approved by the planning director.

(10) Site Access Standards. Access to the cottage housing development shall be provided as follows:

(a) Access to parking shall be from the alley when the cottage housing development abuts a platted alley improved to the city’s engineering design and development standards, or when the director determines that alley access is feasible and desirable to mitigate parking access impacts.

(b) For cottage housing developments where all of the cottages are located on a common lot and alley access is not available, the private drive aisle standards outlined in MMC 22C.130.050, Table 2, shall apply.

(c) For cottage housing developments where the cottages will be subdivided onto individual lots, the city’s PRD and cottage housing street standards as set forth in the engineering development and design standards (“EDDS”) shall apply. The “PRD Access Street” standard shall apply where fewer than 20 dwelling units are proposed, and the “PRD Access Street with Parking” standard shall apply where 20 or more dwelling units are proposed. Modifications to the “PRD Access Street” and the “PRD Access Street with Parking” standards may be requested for sidewalks, planter strips, and on-street parking. The burden to clearly demonstrate the proposed modification meets the requirements of this section is the applicant’s. (Note: it is not likely multiple reductions will be allowed along a single section of road.) If requesting a modification, the applicant shall submit an integrated pedestrian travel, landscape and parking plan as well as other information to demonstrate:

(i) Safe, aesthetically pleasing pedestrian travel is provided throughout the development.

(ii) Pedestrian travel within the development shall be tied to pedestrian travel routes outside the development, actual and/or planned.

(iii) Reduction of planter strips shall require additional equivalent or greater landscaping to benefit the development.

(iv) Any proposed modifications shall allow for efficient flow and movement of automobiles and pedestrians without negatively altering or constraining their movement.

(d) Five-foot-wide pedestrian pathways (sidewalks) must be included to provide for movement of residents and guests from parking areas to homes and other amenities.

(11) Parking Standards. Parking shall meet the following standards:

(a) The number of off-street parking spaces shall be provided as set forth in MMC 22C.130.030, Table 1, and shall meet the dimensions set forth in MMC 22C.130.050, Table 2.

(b) Parking stalls, garages and carports must be screened from public streets or abutting residential properties.

(c) Parking stalls, garages and carports shall be located in the following preferential order:

(d) Parking stalls, garages and carports must meet the front yard setback requirements outlined in subsection (6) of this section.

(e) Parking areas must be in clusters of not more than six adjoining spaces. Landscaping or other architectural features shall separate clusters of parking, and clusters of parking from common areas.

(f) The parking area should not be the major view from the public right-of-way or street. Landscaping, cottages, or the common area should provide the view into the cottage development.

(g) Garages and carports shall be located so their visual presence is minimized, and associated noise or other impacts do not intrude into public spaces.

(h) The architectural design of all garages and carports must be similar and compatible to that of the cottage dwelling units within the development.

(i) Garage and carport rear and side elevations facing the public street or adjacent existing development shall have architectural details to minimize the impact of the facade.

(j) A six-single-vehicle-stall garage or carport is the maximum number allowed in any garage or carport.

(k) Shared detached garage structures shall be reserved for the parking of vehicles owned by the residents of the development. Storage of items which precludes the use of the parking spaces for vehicles is prohibited.

(12) Screening Standards.

(a) Boundaries between cottage dwellings and neighboring properties shall be screened with landscaping to reduce the appearance of bulk or intrusion onto adjacent properties, or otherwise treated (i.e., through setbacks or architectural techniques) to meet the intent of this section.

(b) Yard and open space fencing within the cottage housing development shall not exceed three and one-half feet tall.

(c) Trash and Recycling Container Enclosure and Landscape Screening. All dumpster containers, individual refuse containers, and trash compactors shall be enclosed per the following standards:

(i) All loading, trash, recycling and storage areas shall be located so they are not visible from streets and will be concealed.

(ii) An architectural screen shall surround all sides except the access entry. Building walls of adjacent structures may be used to partially satisfy this requirement. Screen walls shall be a solid visual screen constructed out of metal, concrete, and/or masonry units; or other materials similar to the cottages and garage structures. Required gates and trellises, and other architectural screening elements, shall be designed so that they complement the surrounding buildings unless there is some overriding fire access issue.

(iii) A concrete slab shall be installed as the base material within the enclosure.

(13) Homeowners’ Association. A homeowners’ association and covenants are required for the maintenance of the common areas and buildings.

(14) Requests for Modifications to Standards. The community development director may approve minor modifications to the general parameters and design standards set forth in this chapter, provided the site is constrained due to unusual shape, topography, easements or sensitive areas.

(a) The modification is consistent with the objectives of this chapter.

(b) The modification will not result in a development that is less compatible with neighboring land uses. (Ord. 3366 § 57 (Exh. EEE), 2025; Ord. 3352 § 60 (Exh. EEE), 2025; Ord. 3265 § 4 (Exh. B), 2023; Ord. 3130 § 4 (Exh. B), 2019).

(1) Applicability.

(a) Prior to submitting a building permit application, all development to which these standards apply shall be required to submit a site plan and elevations addressing the standards in this section for administrative review and approval by the community development director.

(b) The site and building design standards of this section apply to multifamily developments, whereas only subsections (2) and (4) of this section apply to single-family and condominium developments.

(c) The crime prevention through environmental design (CPTED) provisions of this section apply to all new multifamily developments of 10 or more units and planned residential developments.

(2) Relationship of Buildings to Site and Street Front.

(a) The site shall be oriented and designed to create an attractive street edge and accommodate pedestrian access. The following provisions apply:

(i) The street edge shall be defined with buildings, landscaping or other features.

(ii) Primary building entrance(s) shall face the street unless it is not feasible due to parcel size, topography, environmental conditions, or other factors as determined by the director, and alternate design elements are incorporated into the facade which enliven the streetscape. Alternatively, for multifamily projects, building entries that face onto a courtyard which is oriented towards the street are acceptable.

(iii) Buildings with individual ground floor entries should face the street to the extent possible. Alternatively, for multifamily projects, configurations where entries face onto a courtyard or open space that is oriented to the street are acceptable.

(iv) Buildings shall provide windows that face the street to provide “eyes on the street” for safety. To meet this requirement, at least 15 percent of the facade facing the street shall be occupied by transparent windows or doors.

(v) Provide for a sidewalk at least five feet wide if there is not space in the public right-of-way.

(vi) Provide building entries that are accessed from the sidewalk; preferably these access ways should be separated from the parking and drive aisles. If access traverses the parking lot, then it should be raised and clearly marked.

(b) The development shall provide site development features that are visible and pedestrian-accessible from the street. These features could include plazas, open space areas, recreational areas, architectural focal points, and access lighting.

(c) The development shall create a well-defined streetscape to allow for the safe movement of pedestrians.

(d) For multifamily residences, no more than 50 percent of the total parking spaces may be located between the building and the primary public street (street from which primary access is obtained) unless it is not feasible due to parcel size, topography, environmental conditions, or other facts as determined by the director. Where the property fronts on more than one public street, this provision applies to only one street frontage.

(e) For multifamily residences, parking lots shall not be located at the intersection of public streets unless no feasible alternative location exists.

Figure 1 – Illustration of facade transparency requirements which enhance safety and the relationship to the street front.

(3) Relationship of Buildings and Site to Adjoining Area.

(a) Where adjacent buildings and neighborhoods are consistent with the comprehensive plan and desired community character, new buildings and structures should consider the visual continuity between the proposed and existing development with respect to building setbacks, placement of structures, location of pedestrian/vehicular facilities and spacing from adjoining buildings. Solar access of the subject and adjacent properties should be considered in building design and location.

(b) Harmony in texture, lines and masses is encouraged.

(c) Attractive landscape transition to adjoining properties shall be provided.

(d) Public and quasi-public buildings and structures shall be consistent with the established neighborhood character.

(4) Landscape and Site Treatment.

(a) Parking lot screening and interior landscaping shall be provided consistent with Chapter 22C.120 MMC. The following criteria shall guide review of plans and administration of the landscaping standards in the zoning code:

(i) The landscape plan shall demonstrate visual relief from large expanses of parking areas.

(ii) The landscape plan shall provide some physical separation between vehicular and pedestrian traffic.

(iii) The landscape plan shall provide decorative landscaping as a focal setting for signs, special site elements, and/or pedestrian areas.

(iv) In locations where plants will be susceptible to injury by pedestrian or motor traffic, they shall be protected by appropriate curbs, tree guards or other devices.

(v) Where building sites limit planting, the placement of trees or shrubs in parkways or paved areas is encouraged.

(vi) Screening of outdoor service yards and other places which tend to be unsightly shall be accomplished by use of walls, fencing, planting, berms or combinations of these.

(vii) Landscaping should be designed to create definition between public and private spaces.

(viii) Where feasible, the landscape plan shall coordinate the selection of plant material to provide a succession of blooms, seasonal color, and a variety of textures.

(ix) The landscape plan shall provide a transition in landscaping design between adjacent sites, within a site, and from native vegetation areas in order to achieve greater continuity.

(x) The landscape plan shall use plantings to highlight significant site features and to define the function of the site, including parking, circulation, entries, and open spaces.

(xi) Where feasible, the landscape plan shall integrate natural approaches to storm water management, including featured low impact development techniques.

(b) Street Landscaping. Where the site plan includes streetscape plantings, the following guidelines apply:

(i) Sidewalks and pathways should be separated from the roadway by planting strips with street trees wherever possible.

(ii) Planting strips should generally be at least five feet in width. They should include evergreen shrubs no more than four feet in height and/or ground cover in accordance with the city of Marysville landscape standards (Chapter 22C.120 MMC) and Marysville administrative landscaping guidelines.

(iii) Street trees placed in tree grates may be more desirable than planting strips in key pedestrian areas.

(iv) Use of trees and other plantings with special qualities (e.g., spring flowers and/or good fall color) are strongly encouraged to unify development.

(c) Exterior lighting shall be part of the architectural concept. Lighting shall enhance the building design and adjoining landscaping. Appropriate lighting levels shall be provided in all areas used by pedestrians or automobiles, including building entries, walkways, parking areas, circulation areas, and other open space areas, in order to ensure safety and security; enhance and encourage evening activities; and provide a distinctive character to the area. New developments shall provide a lighting site plan which identifies lighting equipment, locations and standards, and implements the following design standards:

(i) All public areas shall be lighted with average minimum and maximum levels as follows:

(A) Minimum (for low or nonpedestrian and vehicular traffic areas) of one-half foot candle;

(B) Moderate (for moderate or high volume pedestrian areas) of one to two foot candles; and

(C) Maximum (for high volume pedestrian areas and building entries) of four foot candles.

(ii) Lighting shall be provided at consistent levels, with gradual transitions between maximum and minimum levels of lighting and between lit areas and unlit areas. Highly contrasting pools of light and dark areas shall be avoided.

(iii) Parking lot lighting shall be subject to the provisions set forth in MMC 22C.130.050(3)(d).

(iv) Pedestrian-scale lighting (light fixtures no taller than 15 feet) is encouraged in areas with high anticipated pedestrian activity. All fixtures over 15 feet in height shall be fitted with a full cut-off shield, be dark sky rated, and mounted no more than 25 feet above the ground with lower fixtures preferable so as to maintain a human scale. Lighting shall enable pedestrians to identify a face 45 feet away in order to promote safety.

(v) Light levels at the property line should not exceed 0.1 foot candles (fc) adjacent to business properties, and 0.05 foot candles adjacent to residential properties. All building lights shall be directed onto the building itself and/or the ground immediately adjacent to it. The light emissions should not be visible above the roofline of the building. Light fixtures other than traditional cobra heads are encouraged.

(vi) Uplighting on trees and provisions for seasonal lighting are encouraged.

(vii) Accent lighting on architectural and landscape features is encouraged to add interest and focal points.

(5) Site Design Utilizing Crime Prevention through Environmental Design (CPTED) Principles. Development that is subject to this section shall incorporate the following CPTED strategies into building design and site layout:

(a) Access Control. Guidance of people coming and going from a building or site by placement of real and perceived barriers. Provision of natural access control limits access and increases natural surveillance to restrict criminal intrusion, especially into areas that are not readily observable.

(b) Surveillance. Placement of features, uses, activities, and people to maximize visibility. Provision of natural surveillance helps to create environments where there is plenty of opportunity for people engaged in their normal behavior to observe the space around them.

(c) Territoriality/Ownership. Delineation of private space from semi-public and public spaces that creates a sense of ownership. Techniques that reduce the perception of areas as “ownerless” and, therefore, available for undesirable uses.

Examples of ways in which a proposal can comply with CPTED principles are outlined in the CPTED Guidelines for Project Design and Review, prepared by the city.

(6) Building Design – Human-Scale Standards. The human-scale standards are intended to encourage the use of building components that relate to the size of the human body, and to add visual interest to buildings. “Human scale” addresses the relationship between a building and the human body. Generally, buildings attain a good human scale when they feature elements or characteristics that are sized to fit human activities, such as doors, porches, and balconies. A minimum of three of the following human-scale building elements shall be incorporated into the new development:

(a) Balconies or decks in upper stories, at least one balcony or deck per upper floor on the facades facing streets, provided they are integrated into the architecture of the building;

(b) Bay windows or other window treatments that extend out from the building face;

(c) At least 150 square feet of pedestrian-oriented space for each 100 lineal feet of building facade;

(d) First floor individual windows, generally less than 32 square feet per pane and separated from the windows by at least a six-inch molding;

(e) A porch or covered entry;

(f) Spatially defining building elements, such as a trellis, overhang, canopy, or other element, that defines space that can be occupied by people;

(g) Upper story setbacks, provided one or more of the upper stories are set back from the face of the building at least six feet;

(h) Composing smaller building elements near the entry of pedestrian-oriented street fronts of large buildings;

(i) Landscaping components that meet the intent of these standards; and/or

(j) The director may consider other methods to provide human-scale elements not specifically listed here. The proposed methods must satisfy the intent of these standards.

Figure 2 – An example of balconies that have been integrated into the architecture of the building.

(7) Building Design – Architectural Scale. The architectural scale standards are intended to encourage compatibility of structures with nearby structures, to help the building fit in with its context, and to add visual interest to buildings.

(a) Vertical Facade Modulation. All new residential buildings shall provide modulation (measured and proportioned inflexion or setback in a building’s facade) on facades facing a street, common open space, public area, or common parking area as follows:

(i) Buildings with facades that are 30 feet or longer shall provide vertical modulation of the exterior wall that extends through all floors; provided, that where horizontal modulation is used different stories may be modulated at different depths.

(ii) The minimum modulation depth shall be five feet and the minimum modulation width for each modulation shall be 10 feet. On facades that are 100 feet or longer, the minimum depth of modulation shall be 10 feet and the minimum width for each modulation shall be 20 feet.

(iii) The minimum modulation depth identified in subsection (7)(a)(ii) of this section may be reduced to two feet if tied to a change in color or building materials, and/or roofline modulation as defined in subsection (7)(c) of this section.

(iv) The director may consider departures from these standards, provided the proposed treatment meets or exceeds the intent of these standards.

(b) Facade Articulation. All new residential buildings shall include two of the following articulation features at intervals of no more than 30 feet along all facade facing a street, common open space, public area, and common parking areas:

(i) Repeating distinctive window patterns at intervals of no more than 30 feet (see Figure 3 below for an example).

(ii) Horizontal modulation (upper level step-backs) (see Figure 4). To qualify for this measure, the minimum horizontal modulation shall be five feet.

(iii) Balconies that are recessed or projected from the facade at least 18 inches and integrated with the building’s architecture as determined by the director.

(iv) Change of building materials.

(v) Articulation of the building’s top, middle, and bottom. This typically includes a distinctive ground floor or lower floor design, consistent articulation of middle floors, and a distinctive roofline (see Figures 3 and 4.)

(c) Roofline Modulation. Roofline modulation can be used in order to articulate the structure:

(i) In order to qualify as an articulation element in subsection (7)(b) of this section or in this subsection, the roofline shall meet the following modulation requirement (see Figure 5):

(A) For flat roofs or facades with horizontal eave, fascia, or parapet, the minimum vertical dimension of roofline modulation is the greater of two feet or 0.1 multiplied by the wall height (finish grade to top of the wall) when combined with vertical building modulation techniques described in subsection (7)(a) of this section. Otherwise, the minimum vertical dimension of roofline modulation is the greater of four feet or 0.2 multiplied by the wall height.

(B) Buildings with pitched roofs must include a minimum slope of 5:12 and feature modulated roofline components at the interval required per the applicable standard above.

Figure 3 – Note the repeating distinctive window patterns and the articulation of the building’s top, middle and bottom.

Figure 4 – An example of articulating a building’s top, middle, and bottom by utilizing brick on the ground floor, defined window patterns and articulation treatments on upper floors, and a distinctive roofline.

Figure 5 – Roofline modulation standards.

Figure 6 – Example of good articulation for a multifamily building.

(8) Building Design – Entrances. The intent of the building entrances standards is to ensure that buildings are inviting and accessible, and to encourage pedestrian activity. The principal building entrances of all buildings shall feature the following improvements, unless the director determines an alternate technique better addresses the intent of these standards:

(a) A distinct entry feature that provides weather cover that is at least three feet deep must be provided for the primary entrance(s) to residential units. Figures 7 and 8 demonstrate this requirement.

(b) Access to Residential Units. Ground floor residential units facing a street or common open space shall be directly accessible from the applicable street or open space.

(c) Townhouse Entrances. Townhomes and all other multifamily dwelling units with private exterior ground floor entries shall provide at least 20 square feet of landscaping adjacent to the entry. This is particularly important for units where the primary entrance is next to private garages off an interior access road. Such landscaping areas soften the appearance of the building and highlight individual entries. See Figure 8 for an example of what is desired and Figure 9 for an example of what is unacceptable.

Figure 7 – Weather protection that articulates the front facade is provided.

Figure 8 – Ground floor residential units directly accessible to the street with landscaping defining the entry.

Figure 9 – An example of unacceptable townhouse design where there is no landscaping adjacent to the entries.

(9) Building Design – Details. The building design details standards are intended to ensure that buildings have design interest at all observable distances and to enhance the architecture of multifamily buildings. At closer distances, the most important aspects of a building are its design details, texture of materials, quality of its finishes, and small, decorative elements. Multifamily building facades shall incorporate four architectural details, except that if option e below is used, only three architectural details must be used. Chosen details shall be compatible with the chosen architectural character of the building. Detail options include:

(a) Decorative porch design with distinct design and use of materials.

(b) Decorative treatment of windows and doors such as decorative molding/framing details around all ground floor windows and doors, bay windows, decorative glazing, or door designs and/or unique window designs.

(c) Landscaped trellises or other decorative element that incorporates landscaping near the building entry or entries.

(d) Decorative light fixtures with a diffuse visible light source, such as a globe or “acorn” that is nonglaring or a decorative shade or mounting for each building entry on the facade.

(e) Brick or stonework covering more than 10 percent of the facade.

(f) Decorative building materials that add visual interest, including:

(i) Individualized patterns or continuous wood details.

(ii) Decorative moldings, brackets, wave trim or lattice work.

(iii) Decorative brick or stonework (may be in addition to the brick or stonework credits noted above if they are arranged in a decorative manner that adds visual interest to the facade).

(iv) Other materials with decorative or textural qualities as approved by the director. The applicant must submit architectural drawings and material samples for approval.

(g) Decorative roofline design, including multiple gables and/or dormers or other design that adds distinct visual interest.

(h) Decorative railings, grill work, or terraced landscape beds integrated along the facade of the building.

(i) Decorative balcony design, such as distinctive railings.

(j) Other details that meet the intent of the standards as approved by the director.

Figure 10 – This building uses brick for more than 10 percent of the facade, a decorative mix of materials and colors, decorative entries, and decorative windows to add visual interest.

(10) Window Design for Residential Uses. Building facades shall employ techniques to recess or project individual windows above the ground floor at least two inches from the facade, or incorporate window trim at least four inches in width that features color that contrasts with the base building color. Exceptions will be considered by the director where buildings employ other distinctive windows or facade treatments that add visual interest to the building.

Figure 11 – Acceptable and unacceptable window treatments.

(11) Building Materials. The building materials standards are intended to encourage the use of a variety of high-quality, durable materials that will enhance the visual image of the city; provide visual interest and distinct design qualities; and promote compatibility and improvement within surrounding neighborhoods through effective architectural detailing and the use of traditional building techniques and materials. The following standards apply:

(a) Building exteriors shall be constructed from high-quality, durable materials. Building materials such as masonry, stone, lap-siding, and wood are encouraged.

(b) The following materials are prohibited in visible locations unless an exception is granted by the director based on the integration of the material into the overall design of the structure:

(i) Plywood siding (including T-111 or similar plywood). Board and batten is an exception.

(ii) Corrugated fiberglass.

(iii) Noncorrugated and highly reflective sheet metal.

(iv) Chain link fencing; provided, that the director may approve chain link fencing when it is integrated into the overall site design (chain link fencing is also allowed for temporary purposes such as a construction site, or as a gate for a refuse enclosure).

(12) Blank Walls. The blank wall standards are intended to: reduce the visual impact of large, undifferentiated walls; reduce the apparent size of large walls through the use of various architectural and landscaping treatments; enhance the character and identity of the city; and ensure that all visible sides of buildings provide visual interest. Blank walls visible from a public street, sidewalk, trail, interior pathway, or parking lot are prohibited.

(a) A wall (including building facades and other exterior building walls, retaining walls, and fences) is defined as a blank wall if:

(i) A ground floor wall or portion of a ground floor wall over four feet in height has a horizontal length greater than 15 feet and does not include a transparent window or door; or

(ii) Any portion of a ground floor wall having a surface area of 400 square feet or greater does not include a transparent window or door.

(b) All blank walls visible from a public street, sidewalk, trail, interior pathway, or parking lot shall be treated in one or more of the following measures:

(i) Incorporate transparent windows or doors;

(ii) Install a vertical trellis in front of the wall with climbing vines or plant materials sufficient to obscure or screen at least 60 percent of the wall’s surface within three years. For large blank wall areas, the trellis must be used in conjunction with other treatments described below;

(iii) Provide a landscaped planting bed at least five feet wide, or a raised planter bed at least two feet high and three feet wide in front of the wall. Plant materials must be able to obscure or screen at least 60 percent of the wall’s surface within three years;

(iv) Provide artwork (mosaic, mural, sculpture, relief, etc.) over at least 50 percent of the blank wall surface; and/or

(v) Other method as approved by the director. For example, landscaping or other treatments may not be necessary on a wall that employs high-quality building materials (such as brick) and provides desirable visual interest.

Figure 12 – Blank wall treatments.

Figure 13 – Terraced planting beds effectively screen a large blank wall.

(Ord. 2927 § 3, 2013; Ord. 2870 § 6, 2011; Ord. 2852 § 10 (Exh. A), 2011).

(1) On sites abutting an alley, developments shall have parking areas placed to the rear of buildings with primary vehicular access via the alley, except when waived by the planning director due to physical site limitations or where disallowed by the city’s engineering design and development standards.

(2) When alley access is available, and provides adequate access for the site, its use will be required unless determined to be infeasible or undesirable as determined by the community development director.

(3) When common parking facilities for residences exceed 30 spaces, no more than 50 percent of the required parking shall be permitted between the street property line and any building, except when authorized by the planning director due to physical site limitations.

(4) Direct parking space access to an alley may be used for parking lots with five or fewer spaces.. (Ord. 3366 § 58 (Exh. FFF), 2025; Ord. 3352 § 61 (Exh. FFF), 2025; Ord. 3265 § 5 (Exh. C), 2023; Ord. 2852 § 10 (Exh. A), 2011).

The provisions of this section apply to building permits for single-family dwellings and middle housing, excluding accessory dwelling units and cottage housing; review will be done through the building permit process.

(1) It is the intent of these development standards that single-family dwellings and middle housing be compatible with neighboring properties, friendly to the streetscape, and in scale with the lots upon which they are to be constructed. The director is authorized to promulgate guidelines, graphic representations, and examples of housing designs and methods of construction that do or do not satisfy the intent of these standards.

(2) Entry. Where lots front on a public street, the house shall have doors and windows which face the street. Houses should have a distinct entry feature such as a porch or weather-covered entryway with an entry feature that is at least 60 square feet with no dimension less than six feet.

The director may approve a street orientation or entryway with dimensions different than specified herein; provided, the entry visually articulates the front facade of the dwelling to create a distinct entryway, meets setback requirements, provides weather cover, has a minimum dimension of four feet, and is attached to the home.

(3) Alleys.

(a) If the lot abuts an alley, the garage or off-street parking area shall take access from the alley, unless precluded by steep topography. No curb cuts shall be permitted unless access from the alley is precluded by steep topography.

(b) The minimum driveway length may be reduced to between six and zero feet for garages when the following conditions are met:

(i) An alley is provided for access;

(ii) At least one off-street parking space, in addition to any provided in the garage, is provided to serve that dwelling unit and the stall(s) is conveniently located for that particular dwelling; and

(iii) The applicable total parking stall requirement is met.

(c) The rear yard setback may be reduced to zero feet to accommodate the garage.

(d) If the garage does not extend to the property line or alley, the dwelling unit above the garage may be extended to the property line or alley.

(e) Dwellings with a wall facing an alley must provide at least one window facing the alley to allow observation of the alley.

(4) Auto Courts. Auto courts shall comply with the standards set forth in the city’s engineering design and development standards. Where a consolidated road results in superior site design, circulation, safety or access management, auto courts may be required to be minimized and a consolidated public road provided.

(5) Facade and Driveway Cuts. If there is no alley access and the lot fronts on a public or private street, living space equal to at least 50 percent of the garage shall be flush with or projected forward of the garage, and the dwelling shall have entry, window and/or roofline design treatment which emphasizes the house more than the garage. Where materials and/or methods such as modulation, articulation, or other architectural elements such as porches, dormers, gables, or varied roofline heights are utilized, the director or designee may waive or reduce the 50 percent standard. Driveway cuts shall be no more than 80 percent of the lot frontage; provided, that the director or designee may waive the 80 percent maximum if materials and/or methods to de-emphasize the driveway, such as ribbon driveways, grasscrete surface, or accent paving, are utilized.

(6) Privacy. Dwellings built on lots without direct frontage on the public street should be situated to respect the privacy of abutting homes and to create usable yard space for the dwelling(s). The review authority shall have the discretion to establish setback requirements that are different than may otherwise be required in order to accomplish these objectives.

(7) Individual Identity. Home individuality will be achieved by the following:

(a) Avoiding the appearance of a long row of homes by means such as angling houses, varied street setbacks, and varied architectural design features.

(b) Each dwelling unit shall have horizontal or vertical variation within each unit’s front building face and between the front building faces of all adjacent units/structures to provide visual diversity and individual identity to each unit. Upon building permit application, a plot plan of the entire structure shall be provided by the builder to show compliance with this requirement. The director or designee shall review and approve or deny the building design, which may incorporate variations in rooflines, setbacks between adjacent buildings, and other structural variations.

(c) The same building plans cannot be utilized on consecutive lots. “Flip-flopping” of plans is not permitted; provided, that upon demonstration to the director that the alteration of building facades would provide comparable visual diversity and individual identity to the dwelling units as different building plans, this provision shall not apply. Materials and/or methods which may be utilized to achieve visual diversity include, but are not limited to, use of differing siding material, building modulations and roofline variations.

(d) Side facades visible from streets or shared accesses shall have siding similar to the front facade and windows on a minimum of five percent of the side facade; provided, that the director may allow a reduction in windows where the side facade incorporates other features that provide comparable visual interest.

(8) Landscaping. Landscaping of a size and type consistent with the development will be provided to enhance the streetscape. Landscaping will enhance privacy for dwellings on abutting lots and provide separation and buffering on easement access drives.

(9) Duplexes and Middle Housing. Duplexes and middle housing must be designed to architecturally blend with the surrounding single-family dwellings and not be readily discernible as a duplex or middle housing but appear to be a single-family dwelling, or must comply with the individual identity provisions in subsection (7) of this section where distinct units are proposed (e.g., side-by-side duplex or townhouse units). (Ord. 3366 § 59 (Exh. GGG), 2025; Ord. 3352 § 62 (Exh. GGG), 2025; Ord. 2898 § 12, 2012; Ord. 2852 § 10 (Exh. A), 2011).

The on-site open space and recreation space standards are intended to provide usable, accessible, and inviting open space for residents that enhances residential areas. Multifamily residential uses shall provide open space equivalent to at least

20 percent of the building’s gross floor area. The required area may be satisfied with one or more of the elements listed below:

(1) Common open space accessible to all residents shall count for up to 100 percent of the required open space. This includes landscaped courtyards or decks, gardens with pathways, children’s play areas, or other multipurpose recreational and/or green spaces. Special requirements and recommendations for common spaces include the following:

(a) Space shall be large enough to provide functional leisure or recreational activity area per the director. For example, long narrow spaces less than 20 feet wide rarely, if ever, can function as usable common open space.

(b) Consider space as a focal point of development.

(c) Open space, particularly children’s play areas, shall be visible from dwelling units, positioned near pedestrian activity, and be accessible to all units.

(d) Space shall feature paths, plantings, seating, lighting and other pedestrian amenities to make the area more functional and enjoyable.

(e) Individual entries shall be provided onto common open space from adjacent ground floor residential units. Small, semiprivate open spaces for adjacent ground floor units that maintain visual access to the common area are strongly encouraged to enliven the space.

(f) Separate common space from ground floor windows, streets, service areas and parking lots with landscaping and/or low-level fencing, where desirable.

(g) Space shall be oriented to receive sunlight, facing east, west, or (preferably) south, when possible.

(h) Required setbacks, landscaping, driveways, parking, or other vehicular use areas shall not be counted toward the common open space requirement; provided, that side and rear setbacks may contribute to open space on infill lots when the director determines that the setback area provides functional leisure or recreational area.

(i) Rooftops or rooftop decks shall not be considered as common open space for the purpose of calculating minimum open space area; provided, that the director may consider rooftops or rooftop decks as common open space where usable open space amenities are provided and available to all residents.

(j) Outdoor open space shall not include areas devoted to parking or vehicular access.

(2) The following amenities may be used to satisfy up to 50 percent of the open space requirement. A combination of these amenities may be provided in different ratios; provided, that (i) the total credit for any combination of the following amenities may not exceed 50 percent of the open space requirement, and (ii) the amount of the amenity provided is sufficient to achieve the purpose of the amenity as determined by the director:

(a) Individual balconies that provide a space usable for human activity. To qualify, the balconies shall be at least 36 square feet and have no dimension less than six feet.

(b) Natural areas that function as an amenity to the development, subject to the following requirements and recommendations:

(i) The natural area shall be accessible to all residents. For example, safe and attractive trails provided along or through the natural area where they could serve as a major amenity to the development.

(ii) Steep slopes, wetlands, or similar unbuildable areas shall not be counted in the calculations for required open space unless they provide a visual amenity for all units, as determined by the director.

(c) Storm water retention areas if the facility has natural-looking edges, natural vegetation, and no fencing except along the property line. The design of such areas shall go well beyond functional storm water requirements per the director in terms of the area involved and the quality of landscaping and resident amenities. The side slope of the storm water facilities shall not exceed a grade of 1:3 (one vertical to three horizontal) unless slopes are existing, natural, and covered with vegetation.

Figure 14 – Conditions for storm water to be counted as an amenity

(3) Children’s play equipment and recreational activity space for children and/or teens that include parent seating areas are required in residential complexes with 20 or more units.

Exceptions: age-restricted senior citizen housing; mixed use developments; developments reserved for student housing; and developments located within a quarter mile of safe walking distance to a public park that features a play area.

(4) Active recreation facilities may be provided instead of common open space, subject to the following:

(a) Active recreation facilities may include, but are not limited to, exercise rooms, sports courts, swimming pools, tennis courts, game rooms, or community centers; and

(b) Indoor recreation areas may be credited towards the total recreation space requirement, when the director determines that such areas are located, designed and improved in a manner which provides recreational opportunities functionally equivalent to those recreational opportunities available outdoors.

(Ord. 3366 § 60 (Exh. HHH), 2025; Ord. 3352 § 63 (Exh. HHH), 2025; Ord. 3265 § 7 (Exh. E), 2023; Ord. 2927 § 5, 2013; Ord. 2852 § 10 (Exh. A), 2011).

(1) Unless the open space or recreation space is dedicated to the city pursuant to subsection (2) of this section, maintenance of any open space or recreation space retained in private ownership shall be the responsibility of the owner or other separate entity capable of long-term maintenance and operation in a manner acceptable to the city.

(2) Open space or recreation space may be dedicated as a public park when the following criteria are met:

(a) The dedicated area is at least one and one-half acres in size, except when adjacent to an existing or planned public park;

(b) The dedicated land provides one or more of the following:

(i) Shoreline access;

(ii) Regional trail linkages;

(iii) Habitat linkages;

(iv) Recreation facilities; or

(v) Heritage sites;

(c) The entire dedicated area is located less than one mile from the project site. (Ord. 2927 § 6, 2013; Ord. 2852 § 10 (Exh. A), 2011).

Nothing herein shall prohibit voluntary agreements with the city that allow a payment in lieu of providing on-site open space or recreation space when a proposed development is located within one-quarter mile of an existing or proposed recreational facility; and, in the discretion of the director, the proposed recreation facility will be of greater benefit to the prospective residents of the development. (Ord. 3265 § 8 (Exh. F), 2023; Ord. 2927 § 7, 2013; Ord. 2852 § 10 (Exh. A), 2011).

City acceptance of this payment is discretionary, and may be permitted if:

(1) The proposed on-site recreation space does not meet the criteria of MMC 22C.010.340(2); or

(2) The recreation space provided within a public park in the vicinity will be of greater benefit to the prospective residents of the development. (Ord. 2927 § 8, 2013; Ord. 2852 § 10 (Exh. A), 2011).

Developments shall provide storage space for the collection of recyclables as follows:

(1) The storage space shall be provided at the rate of:

(a) One and one-half square feet per dwelling unit in multiple-dwelling developments except where the development is participating in a public agency-sponsored or approved direct collection program in which individual recycling bins are used for curbside collection;

(b) Two square feet per every 1,000 square feet of building gross floor area in office, educational and institutional developments.

(2) The storage space for residential developments shall be apportioned and located in collection points as follows:

(a) The required storage area shall be dispersed in collection points throughout the site when a residential development comprises more than one building.

(b) There shall be one collection point for every 30 dwelling units.

(c) Collection points may be located within residential buildings, in separate buildings/structures without dwelling units, or outdoors.

(d) Collection points located in separate buildings/structures or outdoors shall be no more than 200 feet from a common entrance of a residential building.

(e) Collection points shall be located in a manner so that hauling trucks do not obstruct pedestrian or vehicle traffic on-site or project into any public right-of-way.

(3) The storage space for nonresidential development shall be apportioned and located in collection points as follows:

(a) Storage space may be allocated to a centralized collection point.

(b) Outdoor collection points shall not be located in any required setback areas.

(c) Collection points shall be located in a manner so that hauling trucks do not obstruct pedestrian or vehicle traffic on site or project into any public right-of-way.

(d) Access to collection points may be limited, except during regular business hours and/or specified collection hours.

(4) The collection points shall be designed as follows:

(a) Dimensions of the collection points shall be of sufficient width and depth to enclose containers for recyclables.

(e) Enclosures for outdoor collection points and buildings used primarily to contain a collection point shall have gate openings at least 12 feet wide for haulers. In addition, the gate opening for any building or other roofed structure used primarily as a collection point shall have a vertical clearance of at least 12 feet.

(f) Weather protection of recyclables shall be ensured by using weather-proof containers or by providing a roof over the storage area.

(5) Only recyclable materials generated on site shall be collected and stored at such collection points. Except for initial sorting of recyclables by users, all other processing of such materials shall be conducted off site. (Ord. 3265 § 9 (Exh. G), 2023; Ord. 2852 § 10 (Exh. A), 2011).

(1) Purpose. The fence standards promote the positive benefits of fences without negatively affecting the community or endangering public or vehicle safety. Fences can create a sense of privacy, protect children and pets, provide separation from busy streets, and enhance the appearance of property by providing attractive landscape materials. The negative effects of fences can include the creation of street walls that inhibit police and community surveillance, decrease the sense of community, hinder emergency access and the safe movement of pedestrians and vehicles, and create an unattractive appearance.

(2) Types of Fences.

(a) The standards apply to walls, fences, trellises, arbors and screens of all types whether open, solid, wood, metal, wire, masonry or other material.

(b) No barbed or razor-wire fence shall be permitted, except for the following:

(i) Confinement of livestock.

(ii) Public facilities, transmitter and transformer sites.

(iii) Government installations where security or public safety is required.

(3) Height.

(a) Access Streets.

(i) Front lot line: Four feet solid or six feet if entirely open-work fence.

(ii) Side lot line: Six feet.

(iii) Rear lot line: Six feet.

(b) Arterial Streets.

(i) Front lot line: Six feet; provided, that the top two feet are constructed as an open-work fence.

(ii) Side lot line: Six feet.

(iii) Rear lot line: Six feet.

(c) When a protective fence is located on top of a rockery, any portion of the fence above a height of six feet shall be an open-work fence.

(d) Open wire mesh or similar type fences may be erected in excess of the maximum heights permitted in this code on the periphery of playgrounds associated with private and public schools and parks, public facilities, transmitter and transformer sites, and government installations where security or public safety is required.

(e) The height of a fence or freestanding wall, retaining wall or combination of the same shall be measured from its top surface, board, rail, or wire to the natural elevation of the ground on which it stands.

(f) Where the finished grade is a different elevation on either side of a fence, the height may be measured from the side having the highest elevation.

(4) Setbacks.

(a) Front Lot Line.

(i) Solid fences greater than four feet in height shall be set back at least 20 feet from the street right-of-way, except in the following circumstances:

(A) For a corner lot the 20-foot setback shall only apply to the street which provides primary access to the lot.

(B) This setback requirement may be waived or modified by the city engineer or his designee if a fence is designed and constructed so that it does not cause a public safety hazard by obstructing visibility of pedestrians or motorists using streets, driveways or sidewalks.

(ii) A four-foot fence, or six-foot fence with the top two feet constructed as an open-work fence, may be constructed on the front property line, provided the fence is designed and constructed so that it does not cause a public safety hazard by obstructing visibility of pedestrians or motorists using streets, driveways or sidewalks.

(c) Rear lot line: No setback requirement.

(d) For special rules relating to fences and walls near fire hydrants, see MMC 14.03.050(2) and the International Fire Code.

(5) Fence Variances.

(a) The community development director shall have authority to administratively grant a variance to the fence requirements outlined in this section. The community development director is authorized to issue variances in cases of special hardships, unique circumstances and practical difficulties. No variance shall be granted which would be detrimental to the public health, welfare or environment.

(b) Variance requests shall be submitted in writing on a form provided by the city. At the time the applicant submits the variance request to the city, the applicant shall also provide written notification of the variance request to immediately adjoining property owners by first class mail or personal service. Said notice shall include an adequate description of the height and location of the proposed fence.

(c) In considering a request for a modification of the fence requirements outlined in subsections (1) through (4) of this section, the community development director shall consider the following factors:

(i) If the proposed fence is designed and constructed so that it does not cause a public safety hazard by obstructing visibility of pedestrians or motorists using streets, driveways or sidewalks;

(ii) The proposed fence will not infringe upon or interfere with utility and/or access easements or covenant rights or responsibilities;

(iii) The increased fence height will not adversely affect adjacent property owners;

(iv) Fences greater than six feet in height are required to obtain a city building permit;

(v) Other information which is relevant and necessary to make a determination as to the validity of the request for variation. Such additional information may include site plans, elevation drawings, and information concerning the surrounding properties and uses.

(d) Each variance request shall be considered on a case-by-case basis, and the resulting decision shall not be construed as setting precedent for any subsequent application.

(e) The decision of the community development director on a variance application shall be final, subject to appeal to the city hearing examiner pursuant to the procedures in Chapter 22G.010 MMC, Article VIII, Appeals. Appeals shall be filed within 14 calendar days of the written decision of the community development director. (Ord. 2898 § 5, 2012; Ord. 2852 § 10 (Exh. A), 2011).

Where a single lot or a combination of lots under single ownership is developed with more than one multiple-family residential building, such property shall not be subsequently subdivided except when each division thereof complies with all requirements of applicable city codes and ordinances. (Ord. 2852 § 10 (Exh. A), 2011).

(1) To qualify for additional units under the affordable housing provisions of MMC 22C.010.070(3), an applicant shall commit to renting or selling the required number of units as affordable housing and meeting the standards of subsections (2) through (6) of this section.

(2) Dwelling units that qualify as affordable housing shall have costs, including utilities other than telephone, that do not exceed 30 percent of the monthly income of a household whose income does not exceed the following percentages of median household income adjusted for household size, for the county where the household is located, as reported by the United States Department of Housing and Urban Development:

(a) Rental housing: 60 percent.

(b) Owner-occupied housing: 80 percent.

Existing developments that do not conform to the development standards of this chapter are subject to the standards of Chapter 22C.100 MMC, Nonconforming Situations. (Ord. 2852 § 10 (Exh. A), 2011).

The standards pertaining to the required number of auto parking spaces, bicycle parking spaces, parking lot placement, parking lot setbacks and internal parking lot pedestrian connections are stated in Chapter 22C.130 MMC, Parking and Loading. (Ord. 2852 § 10 (Exh. A), 2011).

The sign standards are stated in Chapter 22C.160 MMC, Signs. (Ord. 2852 § 10 (Exh. A), 2011).

The landscaping and screening standards are stated in Chapter 22C.120 MMC, Landscaping and Screening. (Ord. 2852 § 10 (Exh. A), 2011).

See Chapter 22G.080 MMC, Planned Residential Developments. (Ord. 2852 § 10 (Exh. A), 2011).

The commercial, industrial, recreation and public institutional zone categories implement the commercial, industrial and recreational goals and policies and land use plan map designation of the comprehensive plan. The zones are for areas of the city designated by the comprehensive plan for commercial, industrial and recreational uses. The difference in the zoning categories reflects the diversity of commercial, industrial and recreation areas in the city. The zones are distinguished by the uses allowed and the intensity of development allowed. A wide range of uses is allowed in each zone. Limits on the intensity of uses and the development standards promote the desired character for the commercial, industrial or recreational area. The development standards are designed to allow a large degree of development flexibility within parameters that support the intent of the specific zone. The standards are intended to provide certainty to property owners, developers and neighbors about the limits of what is allowed in the various zoning categories. (Ord. 2852 § 10 (Exh. A), 2011).

The full names, short names and map symbols of the commercial, industrial, recreation and public institutional zones are listed below.

(Ord. 3331 § 3 (Exh. C), 2024; Ord. 3260 § 5 (Exh. E), 2023; Ord. 3193 § 12, 2021; Ord. 2852 § 10 (Exh. A), 2011).

(1) Neighborhood Business Zone.

(a) The purpose of the neighborhood business zone (NB) is to provide convenient daily retail and personal services for a limited service area and to minimize impacts of commercial activities on nearby properties. These purposes are accomplished by:

(i) Limiting nonresidential uses to those retail or personal services which can serve the everyday needs of a surrounding residential area;

(ii) Allowing for a mix of housing and retail/service uses; and

(iii) Excluding industrial and community/regional business-scaled uses.

(b) Use of this zone is appropriate in neighborhood centers designated by the comprehensive plan which are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(2) Community Business and Community Business – Whiskey Ridge Zones.

(a) The purpose of the community business (CB) and community business – Whiskey Ridge (CB-WR) zones is to provide convenience and comparison retail and personal services for local service areas which exceed the daily convenience needs of adjacent neighborhoods but which cannot be served conveniently by larger activity centers, and to provide retail and personal services in locations within activity centers that are not appropriate for extensive outdoor storage or auto-related and industrial uses. These purposes are accomplished by:

(i) Providing for limited small-scale offices as well as a wider range of the retail, professional, governmental and personal services than are found in neighborhood business areas;

(ii) Allowing for a mix of housing and retail/service uses; provided, that housing is not allowed in the community business – Whiskey Ridge zone; and

(iii) Excluding commercial uses with extensive outdoor storage or fabrication and industrial uses.

(b) Use of this zone is appropriate in community business areas that are designated by the comprehensive plan and are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(3) General Commercial Zone.

(a) The purpose of the general commercial zone (GC) is to provide for the broadest mix of commercial, wholesale, service and recreation/cultural uses with compatible storage and fabrication uses, serving regional market areas and offering significant employment. These purposes are accomplished by:

(i) Encouraging compact development that is supportive of transit and pedestrian travel, through higher nonresidential building heights and floor area ratios than those found in CB zoned areas;

(ii) Allowing for outdoor sales and storage, regional shopping areas and limited fabrication uses; and

(iii) Concentrating large-scale commercial and office uses to facilitate the efficient provision of public facilities and services.

(b) Use of this zone is appropriate in general commercial areas that are designated by the comprehensive plan that are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(4) Downtown Commercial Zone.

(a) The purpose of the downtown commercial zone (DTC) is to provide for the broadest mix of comparison retail, service and recreation/cultural uses with higher density residential uses, serving regional market areas and offering significant employment. These purposes are accomplished by:

(i) Encouraging compact development that is supportive of transit and pedestrian travel, through higher nonresidential building heights and floor area ratios than those found in GC zoned areas;

(ii) Allowing for regional shopping areas, and limited fabrication uses; and

(iii) Concentrating large-scale commercial and office uses to facilitate the efficient provision of public facilities and services.

(b) Use of this zone is appropriate in downtown commercial areas that are designated by the comprehensive plan that are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(5) Mixed Use Zone.

(a) The purpose of the mixed use zone (MU) is to provide for pedestrian- and transit-oriented high-density employment uses together with limited complementary retail and higher density residential development in locations within activity centers where the full range of commercial activities is not desirable. These purposes are accomplished by:

(i) Allowing for uses that will take advantage of pedestrian-oriented site and street improvement standards;

(ii) Providing for higher building heights and floor area ratios than those found in the CB zone;

(iii) Reducing the ratio of required parking to building floor area;

(iv) Allowing for on-site convenient daily retail and personal services for employees and residents; and

(v) Minimizing auto-oriented, outdoor or other retail sales and services which do not provide for the daily convenience needs of on-site and nearby employees or residents.

(b) Use of this zone is appropriate in areas designated by the comprehensive plan for mixed use, or mixed use overlay, which are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(6) Light Industrial Zone.

(a) The purpose of the light industrial zone (LI) is to provide for the location and grouping of non-nuisance-generating industrial enterprises and activities involving manufacturing, assembly, fabrication, processing, bulk handling and storage, research facilities, warehousing and limited retail uses. It is also a purpose of this zone to protect the industrial land base for industrial economic development and employment opportunities. These purposes are accomplished by:

(i) Allowing for a wide range of industrial and manufacturing uses;

(ii) Establishing appropriate development standards and public review procedures for industrial activities with the greatest potential for adverse impacts; and

(iii) Limiting residential, institutional, service, office and other nonindustrial uses to those necessary to directly support industrial activities.

(b) Use of this zone is appropriate in light industrial areas designated by the comprehensive plan which are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(7) Light Industrial With General Commercial Overlay Zone.

(a) The purpose of the light industrial with general commercial overlay zone is to provide for the location and grouping of non-nuisance-generating industrial enterprises and activities involving manufacturing, assembly, fabrication, processing, bulk handling and storage, research facilities, and warehousing along with the broadest mix of commercial, wholesale, service and recreation/cultural uses. This zone is intended as a transitional zone between light industrial and general commercial areas that allows the market to determine whether industrial or commercial uses are the highest and best use of the site.

(b) Use of this zone is appropriate in light industrial areas designated by the comprehensive plan which are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(8) General Industrial Zone.

(a) The purpose of the general industrial zone (GI) is to provide for the location and grouping of industrial enterprises and activities involving manufacturing, assembly, fabrication, processing, bulk handling and storage, research facilities, warehousing and heavy trucking and equipment but also for commercial uses having special impacts and regulated by other chapters of this title. It is also a purpose of this zone to protect the industrial land base for industrial economic development and employment opportunities. These purposes are accomplished by:

(i) Allowing for a wide range of industrial and manufacturing uses;

(ii) Establishing appropriate development standards and public review procedures for industrial activities with the greatest potential for adverse impacts; and

(iii) Limiting residential, institutional, service, office and other nonindustrial uses to those necessary to directly support industrial activities.

(b) Use of this zone is appropriate in general industrial areas designated by the comprehensive plan which are served at the time of development by adequate public sewers, water supply, roads and other needed public facilities and services.

(9) Recreation Zone.

(a) The purpose of the recreation zone (REC) is to establish areas appropriate for public and private recreational uses. Recreation would permit passive as well as active recreational uses such as sports fields, ball courts, golf courses, and waterfront recreation, but not hunting. This zone would also permit some resource land uses related to agriculture and fish and wildlife management.

(b) This recreation zone is applied to all land designated as “recreation” on the comprehensive plan map.

(10) Public/Institutional Zone.

(a) The purpose of the public/institutional (P/I) land use zone is to establish a zone for governmental buildings, churches and public facilities.

(b) This public/institutional zone is applied to all land designated as “public/institutional” on the comprehensive plan map.

(11) Small Farms Overlay Zone.

(a) The purpose of the small farms overlay zone (-SF suffix to zone’s map symbol) is to provide a process for registering small farms, thereby applying the small farms overlay zone and recording official recognition of the existence of the small farm, and to provide encouragement for the preservation of such farms, as well as encouraging good neighbor relations between single-family and adjacent development.

(b) Use of this zone is appropriate for existing and newly designated small farms. (Ord. 3331 § 4 (Exh. D), 2024; Ord. 3260 § 6 (Exh. F), 2023; Ord. 3193 § 13, 2021; Ord. 3159 § 2, 2020; Ord. 2852 § 10 (Exh. A), 2011).

The standards in this chapter state the allowed uses and development standards for the base zones. Sites with overlay zones, subarea or master plans are subject to additional standards. The official zoning maps indicate which sites are subject to these additional standards. (Ord. 2852 § 10 (Exh. A), 2011).

(1) Permitted Uses (P). Uses permitted in the commercial, industrial, recreation and public institutional zones are listed in MMC 22C.020.060 with a “P.” These uses are allowed if they comply with the development standards and other standards of this chapter.

(2) Conditional Uses (C). Uses that are allowed if approved through the conditional use review process are listed in MMC 22C.020.060 with a “C.” These uses are allowed provided they comply with the conditional use approval criteria for that use, the development standards and other standards of this chapter. Uses listed with a “C” that also have a footnote number in the table are subject to the standards cited in the footnote. The conditional use review process and approval criteria are stated in Chapter 22G.010 MMC.

(3) Uses Not Permitted. If no symbol appears in the box at the intersection of the column and the row, the use is not permitted in that district, except for certain temporary uses.

(4) If a number appears in the box at the intersection of the column and the row, the use may be allowed subject to the appropriate review process indicated above, the general requirements of this code and the specific conditions indicated in the development condition with the corresponding number as listed in MMC 22C.020.070.

(5) If more than one letter-number combination appears in the box at the intersection of the column and the row, the use is allowed in that zone subject to different sets of limitation or conditions depending on the review process indicated by the letter, the general requirements of this code and the specific conditions indicated in the development condition with the corresponding number as listed in MMC 22C.020.070.

(6) All applicable requirements shall govern a use whether or not they are cross-referenced in a section. (Ord. 2852 § 10 (Exh. A), 2011).

(b) Notice of the proposed modification shall be provided to contiguous property owners.

(3) Evaluation Criteria. Any proposal to modify use regulations shall not undermine the intent of the standards. The director shall not approve a request for modification unless the proposal provides design elements or other appropriate mitigation equivalent or superior to what would likely result from compliance with the use regulations which are proposed to be modified. The director shall consider the following criteria in making a decision:

(a) The request for modification meets the intent of the standards being modified.

(b) The request for modification does not create any impacts or nuisances that cannot be mitigated, such as access points which are unsafe, noise, dust, odor, glare, visual blight or other undesirable environmental impacts.
