This chapter describes the city’s general requirements for the approval of proposed development and land uses. The permit requirements established by the development code are in Division VII of this title (Permits and Permit Procedures). [Ord. 12-4. DC 2012 § 122-52].

Each land use and/or structure shall be established, constructed, reconstructed, altered, moved, or replaced in compliance with the following requirements:

A. Allowable Uses. The use must be allowed in the district applicable to the site. The basis for determining whether a use is allowed is described in CDC 18.25.030 (Allowable land uses and permit requirements).

B. Permit and Approval Requirements. Any planning permit or other approval required by CDC 18.25.030 (Allowable land uses and permit requirements) shall be obtained before the issuance of any required grading, building, or other construction permit, and before the proposed use is constructed or otherwise established or put into operation, unless the proposed use is listed in CDC 18.25.050 (Exemptions from planning permit requirements).

C. Development Standards, Conditions of Approval. Each use and structure shall comply with the development standards in this chapter, Division IV (Development Standards) and Division V (Standards for Specific Uses) of this title, and any applicable conditions of approval imposed by a new or previously approved permit.

D. Legal Parcel. The site of a proposed development or use shall be on a legally created parcel that is either in compliance with the Subdivision Map Act and the city’s subdivision ordinance or was otherwise legally created prior to the Subdivision Map Act. [Ord. 12-4. DC 2012 § 122-53].

A. Allowable Land Uses. The uses allowed by the development code in each district are listed in Chapters 18.30 through 18.60 CDC, in Tables 18.30.020, 18.35.020, 18.40.020, 18.45.020, 18.50.020, 18.55.020, and 18.60.020 with the type of planning permit (Division VII of this title, Permits and Permit Procedures) required for each use. Each use listed in the tables is described in CDC 18.20.020 (Use classifications).

1. Establishment of New Uses.

a. Any one or more uses identified by Tables 18.30.020 through 18.60.020 as allowable within a specific district may be established on any parcel within that district, subject to the planning permit requirements of subsection (B) of this section and compliance with all applicable requirements of the development code.

b. Where two or more uses are proposed on a single parcel as allowed in Tables 18.30.020 through 18.60.020 for that district, the overall project is subject to the highest permit level required by the planning permit in subsection (B) of this section for any individual use.

2. Uses Not Listed. A use that is not listed in Tables 18.30.020 through 18.60.020 and is determined by the planning division to not be included in CDC 18.20.020 (Use classifications) as a listed land use, is not allowed within the city, except as otherwise provided in subsection (A)(3) of this section, or CDC 18.25.050 (Exemptions from planning permit requirements).

3. Similar and Compatible Uses May Be Allowed. The planning division may determine that a proposed use which is not listed in Chapter 18.20 CDC is allowable as follows:

a. Required Findings. The planning division may determine that a proposed use is similar to and compatible to a listed use and, therefore, may be allowed after first making all of the following findings:

i. The characteristics of, and activities associated with, the use are similar to one or more of the listed uses and will not involve a greater intensity (such as increased traffic, noise, hours of operation, number of employees, outside storage, etc.) than the uses listed in the district;

ii. The use will be consistent with the purposes of the applicable district;

iii. The use will be consistent with the general plan and any applicable specific plan and all development and planning permit requirements;

iv. The use will be compatible with the other uses allowed in the district; and

v. The use is not listed in another district.

b. Applicable Standards and Permit Requirements. When the planning division determines that an unlisted use qualifies as a “similar use,” the proposed use shall be allowed in the same districts as the listed use and subject to the permit requirements listed in Tables 18.30.020 through 18.60.020. If the listed use is allowed with a zoning clearance, an administrative permit shall be required and findings supporting the determination shall be documented in the approval.

c. Referral for Determination. The planning division may refer the determination of whether a proposed use qualifies as a similar and compatible use directly to the planning commission for a determination at a public meeting.

d. Appeal. A determination of similar and compatible use may be appealed in compliance with Chapter 18.510 CDC (Appeals and Calls for Review).

B. Permit Requirements. Tables 18.30.020 through 18.60.020 in Chapters 18.30 through 18.60 CDC specify the type of permit or approval for each allowable use. Permit or approvals include:

1. Zoning Clearance. Use is permitted subject to compliance with all applicable provisions of the development code, subject to obtaining a zoning clearance (Chapter 18.410 CDC), and shown as “ZC” in the tables. A zoning clearance is a stamp, signature, or other official notation on approved plans, business license or similar.

2. Administrative Permit. Use is allowed subject to approval of an administrative permit (Chapter 18.420 CDC), and shown as “AP” in the tables (staff approval).

3. Minor Use Permit. Use is allowed subject to the approval of a minor use permit (Chapter 18.435 CDC), and shown as “MP” uses in the tables (zoning administrator approval).

4. Use Permit. Use is allowed subject to the approval of a use permit (Chapter 18.435 CDC), and shown as “UP” uses in the tables (planning commission approval).

5. Not Allowed. Not allowed in particular districts, and shown as “–” in the tables or not shown in the list of uses for any district.

C. Additional Requirements.

1. Uses with a section number referenced under “Additional Requirements” are subject to the specific requirements in Division V of this title (Standards for Specific Uses).

2. Uses authorized with the approval of a planning permit may also require design and site development review (Chapter 18.415 CDC), a building permit, or other permit, as required by the Concord Municipal Code (CMC).

D. Footnotes. Uses that specify a permit type followed by a footnote are allowed, subject to the footnote limitation. The footnote numbering always contains the same limitation whenever used throughout the tables, for example, “(1) Not allowed on properties directly facing Todos Santos Plaza or on the ground floor for properties not facing Todos Santos Plaza” is used whenever applicable to that specific requirement. The footnote (1) will not be used to reference any other provision. The footnotes listed at the end of each table are specific to the footnotes referenced within that table. Not all footnotes are applicable to every table. The standard footnotes are as follows:

1. All Allowed Uses and Permit Requirements (Tables 18.30.020, 18.35.020, 18.40.020, 18.45.020, and 18.50.020) Footnotes.

(10) Allowed with residential use only.

2. All Development Standards (Tables 18.30.030, 18.30.040, 18.35.030(B), 18.40.030, 18.45.030 and 18.50.030) Footnotes.

(1) Additional requirements may apply pursuant to Division IV (Development Standards) and Division V (Standards for Specific Uses) of this title.

(2) Unless otherwise approved through a planned unit development (PUD) use permit.

(3) Measured from property line or back of sidewalk (whichever is less) to the face of building or structure.

(4) In no case shall any structure be erected closer than 45 feet (50 feet in RR-40) from the centerline of any street; provided, that where four or more lots in a block on the same side of the street have been improved with buildings, the minimum requirement shall be the average of improved lots if less than 20 feet, or less than 25 feet in RR-20, or less than 30 feet in RR-40.

(5) Minimum for each side.

(6) Standard does not apply to small, independent parcels corresponding to individual dwellings within a larger multifamily residential, mixed-use, or townhome development.

(12) Corner lots adjacent to an R or NTS district, corner side yard shall be minimum 10 feet. Where side or rear lot line abuts a lot in an R or NTS district, the minimum side or rear yard shall be the same as required in abutting R or NTS district.

(13) Height shall comply with Contra Costa County airport land use plan. See Chapter 18.100 CDC, Airport Overlay (A).

E. New Tenants in Existing Buildings. New tenants in existing multi-tenant office buildings, multi-tenant buildings in business parks, multi-tenant shopping centers, and multi-tenant office buildings and commercial buildings in the WMX, DMX, and DP districts shall be allowed with a zoning clearance when replacing a use in the same or similar use classification as listed in Chapter 18.20 CDC, Article I (Use Classifications). Other requirements for design and site development review and property upgrades may apply, as required by the development code. [Ord. 13-5; Ord. 12-4. DC 2012 § 122-54].

As of the effective date of the ordinance codified in this title, no development shall be approved using the planned district (PD) zoning district. Existing residential development approved in the planned district zoning district shall retain the (PD) zoning designation until and unless the property is redeveloped. The purpose of the planned district was to provide for development and site design which better responded to unique environmental conditions in furtherance of the general plan by permitting varied setbacks, diverse lot sizes, and other variations to the residential development standards. The development standards were established with the approval of a preliminary development plan by the city council. However, many of the preliminary development plans for residential planned district development and/or their subsequent use permit approval did not provide a sufficient written record to document the development standards and guide the approval of changes to properties over time. Where no record of development standards exists for a specific residential planned district, Table 18.30.030, RR and RS Districts Development Standards, and Table 18.30.040, RL, RM, RH Districts Development Standards, shall be used to determine lot coverage, setbacks and building height by using the area of the subject lot to determine the equivalent zoning category. For those residential planned districts which do include a written record of development standards, those conditions of approval shall remain in effect. [Ord. 12-4. DC 2012 § 122-55].

The planning permit requirements of the development code do not apply to the uses, structures, and activities identified below. These are allowed in all districts, subject to compliance with this section.

This chapter lists the uses that may be permitted within the residential zoning districts, the type of permit or approval required for each use, and basic development standards for the site and building. The purpose of each district is as follows:

A. RR – Rural Residential. The RR district is applied to areas of the city appropriate for rural single-family residential development or clustered development at densities up to two and one-half units per net acre. Designators (RR-40, RR-20, and RR-15) are used to denote minimum lot sizes of 40,000 square feet, 20,000 square feet, and 15,000 square feet, respectively. The RR district is consistent with and implements the rural residential (RR) land use designation of the general plan.

B. RS – Residential Single-Family. The RS district is applied to areas of the city appropriate for single-family residential uses in neighborhoods at densities of two and one-half to 10 units per net acre, subject to appropriate standards. The RS zoning districts generally apply to the single-family residential districts with development existing at the time of the adoption of this development code. The specific allowable density for each parcel is shown on the zoning map by a numerical suffix residential density designator (RS-12, RS-10, RS-8, RS-7.5, RS-7, and RS-6) corresponding to the minimum lot size (12,000, 10,000, 8,000, 7,500, 7,000 and 6,000, respectively). The RS district is consistent with and implements the low density residential (LDR) land use designation of the general plan.

C. RL – Residential Low Density. The RL district is applied to areas of the city appropriate for low density residential uses in a neighborhood with predominately detached single-family dwellings, but allows a diversity of compatible housing types and lot sizes from larger lot single-family dwellings to cottages, cluster, courtyard, and patio homes, and duplexes, at densities of two and one-half to 10 units per net acre. The RL district is consistent with and implements the low density residential (LDR) land use designation of the general plan.

D. RM – Residential Medium Density. The RM district is applied to areas of the city appropriate for residential uses with attached and detached dwellings, including a variety of housing types such as small lot single-family dwellings, townhomes, row houses, and cluster housing, at densities of 11 to 33 units per net acre, with provisions for appropriately scaled and located live/work units. The RM district is consistent with and implements the medium density residential (MDR) land use designation of the general plan.

E. RH – Residential High Density. The RH district is applied to areas of the city appropriate for compact, high density, multifamily residential development including apartments, townhomes, and condominiums at densities ranging from 33 to 100 units per net acre, with limited provisions for appropriately scaled and located live/work units. The RH district is consistent with and implements the high density residential (HDR) land use designation of the general plan. [Ord. 17-11 § 3 (Exh. 10); Ord. 12-4. DC 2012 § 122-77].
