Lake Oswego City Zoning Code

LOC 50.03

Use Regulations and Conditions

§ 50.03.001 Introduction to the Use Table.

Introduction to the Use Table.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012]
Tables 50.03.002-1, Residential Districts Use Table, and 50.03.002-2, Commercial, Mixed Use, Industrial, and Special Purpose Districts Use Table, list land uses and indicate whether they are allowed by right or with a conditional use permit, or prohibited in each base zone district. The use table also includes references to any additional regulations applicable to that use.

§ 50.03.002 Use Table.

How to Use.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2723, Amended, 10-18-2016]
Permitted Uses.
A "P" in a cell of a use table indicates that the land use is allowed by right in that base or overlay zone, subject to compliance with the use-specific standards referenced in the final column of the use table. Permitted uses are subject to all other applicable requirements of this Code, including those set forth in LOC § 50.06, Development Standards. Uses accessory to a permitted use are allowed regardless of whether they are listed separately in the use table.
Conditional Uses.
A "C" in a cell of a use table indicates that the land use is allowed in that base or overlay zone only upon approval of a conditional use permit as described in LOC § 50.07.005, Conditional Use Permits, including the specific conditions listed in LOC § 50.07.005.3, and compliance with any usespecific standards referenced in the use table. Uses subject to a conditional use permit are subject to all other applicable requirements of this Code, including those set forth in LOC § 50.06, Development Standards. Uses accessory to a conditional use are allowed regardless of whether they are listed separately in the use table.
Accessory Uses.
An "A" in a cell of a use table indicates that the land use is expressly allowed in that base or overlay zone as an accessory use to a permitted use or an approved conditional use. In addition to those expressly listed, all uses that are secondary and subordinate to a permitted or approved conditional use, and are frequently found in connection with that permitted or approved conditional use, are allowed as accessory uses. A use is "accessory," when the use is (i) generally accepted as accessory to a primary use based on state of the industry, (ii) the accessory use is secondary to the primary use, (iii) the impacts of the accessory use do not significantly alter the impacts of the primary use (e.g., traffic volume), and (iv) the accessory use is not the same size or scale as would be found for a primary use elsewhere.
Prohibited Uses.
A blank cell in a use table indicates that the land use is prohibited in that base or overlay zone district.
Overlay Districts Provisions Govern.
When a property is located within the boundaries of an overlay district, the use table provisions for that overlay district prevail over those in the base zone district. For example, if a use is prohibited in the base zone district where the property is located, but is a permitted use in an overlay district applicable to the same property, then the use is allowed on that property. On the other hand, if a use is listed as a permitted use in the base zone district but is listed as a conditional use in an overlay zone district applicable to the same property, then the use is a conditional use for that property. Where a property is located in more than one overlay district, then the most restrictive use provision in those overlay zone districts shall apply to the property.
Use-Specific Standards and Table Notes.
There may be additional standards that apply to specific permitted or conditional uses. Those additional standards are either identified in a note at the end of the table or cross-referenced under the “use specific standards” column in the use table. The cross-referenced standards appear in LOC § 50.03.003, Use-Specific Standards, immediately following the use table.
Authorization for Similar Uses.
The City Manager may authorize that a use not specifically named in the permitted, conditional or prohibited uses of a district be included among the allowed uses, if the use 1) is similar to and of the same general type as the uses specifically allowed; 2) is consistent with the Comprehensive Plan; and 3) has similar intensity, density, off-site impacts and impacts on community facilities as uses permitted in the zone. However, the City Manager may not authorize a use already specifically permitted in any other zoning district. A person disagreeing with the City Manager’s decision may appeal that decision to the Planning Commission pursuant to LOC § 50.07.003.7.b, Appeal of Minor Development Decision.

Attached, Residential Townhome Uses in West Lake Grove.
Subject to the following conditions, in addition to the other provisions of this Code:
The minimum net density area for attached townhome housing is 2,500 sq. ft./lot area per unit.
The minimum required lot width shall be 17 ft. The maximum lot coverage shall be 60%, excluding parking.
Each unit of attached townhome housing shall be constructed on a separate lot.
Within the WLG RMU zone:
Attached townhomes are allowed solely or in conjunction with office uses in the same building.
When a combination of office-commercial and attached townhome residential uses are proposed together on the same site and in separate buildings, the commercial structure(s) shall front on Boones Ferry Road. Residential buildings shall occupy the rear portion of the parcel which is most proximate to the surrounding residential zoning districts.
Within the WLG R-2.5 zone:
The use is "Attached for-sale residential townhomes."
When subdivisions are proposed in the WLG R-2.5 zone, a minimum density of 80% of the maximum allowed by the zone is required. For purposes of this subsection, the number of lots required shall be determined by dividing the net developable area by the minimum lot size per unit required in the underlying zone, and multiplying this number by 0.8. The result shall be rounded up for any product with a fraction of 0.5 or greater and rounded down for any product with a fraction of less than 0.5. The requirements of this subsection are subject to the exceptions contained in LOC § 50.04.003.10, Exceptions to the Minimum Density Requirement for All Zones.
Manufactured Homes.
General Provisions.
Manufactured Homes Permitted on Individual Lots and Parcels.
Manufactured homes are permitted on individual lots or parcels in all residential zones as permitted in Table 50.03.002-1: Residential Districts Use Table, in accordance with the placement standards below and all other provisions of this Code which apply to conventionally built dwellings.
Deed Covenants or Restrictions.
Nothing in these provisions shall be interpreted as superseding deed covenants or restrictions.
Manufactured Housing Construction and Safety Standards (HUD Code).
Title VI of the 1974 Housing and Community Development Act (42 USC 5401 et seq.) as amended and rules and regulations adopted thereunder; and including information supplied by the manufacturer which has been stamped and approved pursuant to HUD Rules by a "Design Approval Primary Inspection Authority"; and regulations and interpretations of the Act by the Oregon Department of Commerce; all of which became effective for mobile/manufactured home construction on June 15, 1976, shall be utilized as the minimum construction standard of the City of Lake Oswego to which all manufactured home placements shall comply except as provided otherwise by this section.
State Standards.
Where standards for manufactured home construction and placement are established by state law or Department of Commerce Administrative Rules, such requirements shall apply in addition to those of this section.
Terms and Definitions.
For purposes of this section only, the definitions of terms used herein and not defined in this Code shall be as defined in ORS Chapter 446 or OAR Chapter 918, Div. 500 as amended.
Manufactured Home Placement Standards (Individual Lots).
The manufactured home shall be multi-sectional and enclose a space of not less than 1,000 sq. ft.
Bear an insignia of compliance with the Manufactured Housing Construction and Safety Standards Code and be:
A new or not previously occupied unit; or
Be found upon inspection to be in excellent condition and free of structural, electrical, mechanical, and plumbing defects, any of which must be corrected prior to placement.
Transportation mechanisms including wheels, axles and hitch must be removed. The manufactured home shall be placed on an excavated and back-filled foundation and enclosed at the perimeter such that the finished floor elevation of the manufactured home is located not more than 12 in. above grade. The perimeter enclosure shall be a nonreflective material and give the outward appearance of a concrete, stone or masonry foundation. This material shall be of weather resistant, noncombustible or self extinguishing materials. The materials below grade and for a distance of six in. above finish grade shall be resistant to decay or oxidation.
All load bearing foundations, supports, and enclosures shall be installed in conformance with the Oregon Department of Commerce regulations (OAR, Chapter 814, Division 23) and with the manufacturer’s installation specifications.
Have utilities connected in accordance with City of Lake Oswego and Oregon Department of Commerce requirements and manufacturer’s specifications.
The manufactured home shall have a pitched roof at a minimum of three ft. in height for each 12 ft. in width. Eaves must extend at least one ft. from the intersection of the roof and the exterior walls.
The manufactured home shall have exterior siding and roofing which is similar to the exterior siding and roofing material commonly used in the community or which is comparable to the predominant materials used on surrounding dwellings (greater than 50%) within 300 ft. of the subject property.
The manufactured home shall have either an attached or detached garage constructed at the same time the manufactured home is placed on the site or prior to occupancy. The garage shall be constructed of like materials as the manufactured home. An attached carport shall be allowed if more than 50% of homes within 300 ft. of the subject do not have garages.
Garages and carports shall be constructed to the Oregon State Structural Specialty Code.
If new or previously unoccupied, the manufactured home shall be certified by the manufacturer to have an exterior thermal envelope meeting performance standards which reduce heat loss levels equivalent to the performance of single-family dwellings constructed under the State Building Code as defined by ORS 455.010.
Placement Permit.
Requirements.
Prior to the location, relocation, or establishment of any manufactured home, the homeowner or authorized representative shall secure from the Building Official a placement permit which states that the building and its location conform with these and other relevant standards of this Code. Each application for a placement permit shall be accompanied by:
A plot plan as required for all dwelling units and elevations or photographs of all sides of the home; drawings showing exterior dimensions; information illustrating the type of roofing and siding materials, foundation support system; and foundation enclosure method and materials.
A copy of the manufacturer’s approved instructions to be used for installation purposes.
An agreement signed by the homeowner or authorized representative pledging compliance with the terms set by the Building Official in the placement permit and other information as may be required for enforcement of these standards.
Issuance of Permit.
Following receipt of the required information, the placement permit shall be issued by the Building Official within ten days if all requirements have been met.
Denial and Revocation of Placement Permit.
The Building Official shall deny a placement permit which does not provide the proper information or which proposes to site a manufactured home not in conformance with the requirements of this Code.
The Building Official shall revoke a placement permit when such permit was issued on the basis of incorrect or misleading information. In this case the applicant shall cease work on the placement and/or occupancy of the unit and reapply for a placement permit and pay the required fees within five days of written notification of revocation by the Building Official.

Avoid damage to adjacent properties from tower failure and falling ice, through engineering and careful siting of tower structures;
Maximize use of any new transmission tower and any existing suitable structures to reduce the need for additional towers; and
Allow transmission towers in residential areas only when necessary to meet functional requirements of the telecommunications industry.
Applicability.
These standards shall apply to new telecommunication facilities and collocated telecommunication facilities and not pre-existing towers or pre-existing antennas.
Approval Criteria for Collocated Facilities.
Site Size.
No minimum lot size shall apply when a telecommunications facility is collocated on an existing building or structure.
Facilities for Collocation.
Priorities for Facilities.
Collocation shall occur in the following order of facilities:
Facilities where the collocated facility will project not more than ten ft. higher than the highest point of the existing facility:
Previously approved telecommunications tower;
Existing nonconforming telecommunications tower;
Existing buildings;
Utility (electric, cable, telephone, etc.) and light poles.
Facilities where the collocated facility will project more than ten ft. higher than the highest point of the existing facility:
Previously approved telecommunications tower;
Existing nonconforming telecommunications tower;
Utility (electric, cable, telephone, etc.) and light poles;
Existing buildings.
Suitability of Facility for Collocation.
To determine the suitability of the existing facility for the proposed collocation facility or structure, the applicant must show that:
There are no reasonably feasible telecommunication facilities in a higher classification under subsection 5.g.iii(2)(a) of this section that can meet the requirements of this subsection for a collocated facility and provide the necessary telecommunication service;
The addition of the antenna equipment will not interfere with the normal operation of utilities or existing transmission facilities and the collocated facility complies with the height limit in subsection 5.g.iii(3) of this section;
The collocation improvements must satisfy the standards for the underlying zone, except as provided by subsection 5.g.iii(3) of this section;
The existing structure, if structurally enhanced in order to permit collocation, does not result in a decrease of the setback of the reconstructed structure as described in subsection 5.g.iii(1) of this section and the height of the reconstructed facility complies with the height limit contained in subsection 5.g.iii(3) of this section as applied to the existing structure prior to replacement or reconstruction; and
The collocation may not involve the removal of any previously approved landscaping/buffering.
Height Limit.
Collocated facilities are exempt from the height limits of the underlying zone, but shall be no more than ten ft. taller than the existing structure in a residential zone, a mixed residential/commercial zone, or Public Functions zone, or no more than 20 ft. taller than the existing structure in a commercial, public use, or industrial zone.
Exceptions: A collocated facility shall be no taller than the existing facility where the height of the existing facility has previously been increased in excess of the height limit of the underlying zone as a result of approval of a prior collocation application pursuant to this section.
Visual Impact.
All ancillary facilities shall be screened, hidden or disguised.
Antennas shall be screened, hidden or disguised, or shall be painted or colored to blend into the structure or surroundings.
Processed as New Facility.
A proposed collocated facility that does not comply with the approval criteria for collocated facilities shall be processed as a new facility.
Approval Criteria for New Facilities.
Site Size.
A new facility shall be sited on a parcel of a size and shape that complies with the following criteria:
Setbacks – Tower.
The tower footprint shall be set back at least two-thirds the tower height from any property line. This setback may be reduced if the applicant can demonstrate that:
The shape or configuration of the parcel prevents compliance with the setback standard or that a reduction in setback is necessary to take advantage of screening opportunities (such as tall trees, tree groves, buildings, or other tall elements) not available within the required setback area;
The reduction in setback is the minimum required to best camouflage the facility;
Adequate clearance between the facility and property line can be provided to accommodate landscaping and fencing; and
The reduction in setback will not cause a greater visual impact to adjacent uses.
Setbacks – Ancillary Facilities.
Ancillary facilities shall be set back the same as required for primary structures of the zone, except that the side or rear yard setback may be reduced in a residential zone if the ancillary facilities meet the criteria in LOC § 50.03.004.2.b.
The tower pad shall be sited in a location that permits additional expansion to accommodate future collocated ancillary facilities. The tower shall be located centrally on this pad. This standard shall not apply to antennas attached to existing structures or towers located on rooftops.
A licensed structural engineer’s analysis shall be submitted to demonstrate that the potential impact of tower failure and ice falling from the tower will be accommodated on site.
Separation from Pre-Existing Towers.
New towers shall be separated from existing towers by at least the following distances, measured in a straight line from the base of the proposed new tower to the base of any pre-existing tower:

Collocation to Be Explored; Accommodated.
Before an application for a new transmission tower is accepted, applicants shall demonstrate that they have exhausted all practicable collocation options within the proposed service area pursuant to LOC §§ 50.07.004.12.a.i and 50.07.004.12.a.iv including placement of antennas on existing tall structures and placing multiple antennas or attachments on a single tower. To demonstrate that all practicable collocation options have been exhausted, the applicant shall demonstrate that:
No existing towers or support structures, or approved but not yet constructed towers or support structures, are located within the geographic area required to meet the applicant’s engineering requirements;
Existing towers or support structures are not of sufficient height to meet the applicant’s engineering requirements;
Existing towers or support structures do not have sufficient structural strength to support the applicant’s proposed antenna and related equipment;
The applicant’s proposed antenna would cause electromagnetic interference with the antenna on the existing tower or support structure, or the existing antenna would cause interference with the applicant’s proposed antenna; or
There are other limiting factors that render existing towers and support structures unsuitable.
Accommodation of Future Collocation.
New towers shall be constructed so as to accommodate future collocation, based on expected demand for transmission towers in the service area. Towers shall be designed so as to accommodate a minimum expansion of three two-way antennas for every 40 vertical ft. of tower.
Multiple Attachments on Utility Towers.
In conformance with the Telecommunication Act of 1996, Section 703, a utility shall provide any telecommunications carrier with nondiscriminatory access to any pole, duct, conduit, or right-of-way owned or controlled by it, unless there is insufficient capacity or access cannot be granted for reasons of safety, reliability, and generally applicable engineering purposes.
Ancillary facilities for collocated facilities shall be set back the same as required for primary structures of the zone, except that the side or rear yard setback may be reduced in a residential zone if the ancillary facilities meet the criteria in LOC § 50.03.004.2.b.
Height.
New telecommunication facilities shall not exceed the height limits of the underlying zone, unless the applicant demonstrates that:
There is a service area need for the proposed facility at the proposed location;
The increase in height above the maximum allowed height for the zone is the minimum increase necessary to eliminate service shadows;
That providing coverage with telecommunications facilities which comply with the height requirements of the zone would result in unacceptable proliferation of such facilities. For the purposes of this subsection, "unacceptable proliferation" means an increase in the number of transmission towers by a factor of four in order to achieve the same level of adequate service. An increase in the number of transmission towers shall not include facilities or towers that would qualify as collocated facilities;
The negative visual impacts on adjacent properties can be minimized by screening or disguising the facility.
The applicant may be required to pay for an independent radio frequency engineer or similar consultant to verify the need for this request.
Visual Impact.
The applicant shall demonstrate that telecommunications facilities will have the least practicable visual impact on the environment, considering technical, engineering, economic, and other pertinent factors.
The height and mass of the telecommunications facilities shall not exceed that essential for its intended use and public safety, as demonstrated in a report prepared by a licensed structural engineer.
Telecommunications facilities 200 ft. or less in height shall be camouflaged to ensure the facility is visually subordinate to surrounding objects and colors.
Towers more than 200 ft. in height shall be painted in accordance with the Oregon State Aeronautics Division and Federal Aviation Administration. Applicants shall attempt to seek a waiver from OSAD and FAA marking requirements. When a waiver has been granted, towers shall be painted and/or camouflaged in accordance with subsection 3.e.iv(4)(b) of this section.
Accessory Uses.
Accessory uses shall include only building facilities that are necessary for transmission function and associated satellite ground stations, and shall not include broadcast studios (except for emergency broadcast), offices, vehicle storage areas, nor other similar uses not necessary for the transmission or relay function. No unenclosed storage of materials is allowed.
Lighting.
No lighting shall be permitted on transmission towers except that required by the Oregon State Aeronautics Division or Federal Aviation Administration. This standard shall not prevent shared use or replacement of an existing light pole. For collocation on existing or replaced light poles, the transmission tower shall have no net increase to the spread, intensity, or direction of the existing light source.
Fences and Landscaping.
The tower(s) and ancillary facilities shall be enclosed by a six ft. fence meeting the requirements of LOC § 50.06.004.2.
Landscaping shall be placed outside of fences and shall consist of fast growing vegetation placed densely so as to form a solid hedge with a minimum planted height of six ft.
For new towers, landscaping and fencing shall be compatible with other nearby landscaping and fencing.
Where antennas or towers and ancillary facilities are to be located on existing buildings or structures and are secure from public access, landscaping and fencing requirements may be waived.
Signs.
One non-illuminated sign, not to exceed two sq. ft., shall be provided at the main entrance to the facility stating a contact name and phone number for emergency purposes. Signs shall not be placed on towers and antennas.
Abandoned Facilities.
A telecommunication facility that is unused for a period of six consecutive months or longer is hereby declared abandoned. Abandoned facilities shall be removed by the property owner no later than 90 days from date of abandonment. Failure to remove an abandoned facility is declared a public nuisance and is subject to the penalties established by LOC Article 34.04. Upon written application, prior to the expiration of the six-month period, the City Manager shall, in writing, grant a six-month extension for reuse of the facility. Additional extensions beyond the first six-month extension may be granted by the City Manager subject to any conditions required to bring the project or facility into compliance with current law(s) and make compatible with surrounding development.
Telecommunications Facilities in Residential or Mixed Residential/Commercial Zones.
In addition to compliance with the approval standards in LOC §§ 50.03.003.5.g.iv and 50.07.004.12, and the general conditional use criteria in LOC § 50.07.005, Conditional Use Permits, telecommunications facilities designated as a conditional use in residential or mixed residential/commercial zones shall comply with the following standards:
New telecommunications facilities shall not be located on a parcel containing an existing single-family dwelling or middle housing.
Antenna(s) must be located no closer than 35 ft. from any habitable structure. Tower guy anchors must meet the normal setbacks of the underlying zone.
If the proposed facility will exceed the 50 ft. height limitation of the Lake Oswego Charter in a residential zone, the applicant shall demonstrate that:
The facility could not feasibly be located outside of a residential zone;
There are no alternatives available to meet the required coverage area; and
The height is no taller than necessary to provide adequate transmission.
