18.04.020 Purposes

A.    The general purposes of the residential districts contained in this chapter are as follows:

1.    To provide a sustainable residential development pattern for future generations.

2.    To encourage development of attractive residential areas that provide a sense of community and contain a variety of housing types to accommodate different lifestyles and household sizes.

3.    To maintain or improve the character, appearance, and livability of established neighborhoods by protecting them from incompatible uses, excessive noise, illumination, glare, odor, and similar significant nuisances.

4.    To establish a compact growth pattern to efficiently use the remaining developable land; enable cost effective extension and maintenance of utilities, streets and mass transit; and enable development of affordable housing.

5.    To enable community residents to reside and work within walking or bicycling distance of mass transit, employment centers, and businesses offering needed goods and services in order to reduce traffic congestion, energy consumption, and air pollution.

6.    To provide for development of neighborhoods with attractive, well connected streets, sidewalks, and trails that enable convenient, direct access to neighborhood centers, parks, and transit stops.

7.    To ensure adequate light, air, and readily accessible open space for each dwelling unit in order to maintain public health, safety, and welfare.

8.    To ensure the compatibility of dissimilar adjoining land uses.

9.    To protect or enhance the character of historic structures and areas.

10.    To provide residential areas of sufficient size and density to accommodate the city’s projected population growth, consistent with Section 36.70A.110, RCW.

11.    To preserve or enhance environmental quality and protect ground water used as a public water source from contamination.

12.    To minimize the potential for significant flooding and allow recharge of ground water.

13.    To allow innovative approaches for providing housing, consistent with the policies of the Comprehensive Plan.

14.    To ensure that development without municipal utilities is at a density and in a configuration that enables cost effective urban density development when municipal utilities become available.

B.    The additional purposes of each individual residential district are as follows:

1.    Residential - 1 Unit Per 5 Acres. This designation provides for low-density residential development in designated sensitive drainage basins in a manner that protects aquatic habitat from degradation.

2.    Residential Low Impact (RLI). To accommodate some residential development within sensitive drainage basis at densities averaging from two (2) to four (4) units per acre, provided that the development configuration avoids stormwater and aquatic habitat impacts.

3.    Residential - 4 Units per Acre (R-4 and R-4CB). To accommodate residential development in areas sensitive to stormwater runoff in a manner and at a density (up to four (4) units per acre) that avoids stormwater related problems (e.g., flooding and degradation of environmentally Critical Areas).

4.    Residential 4-8 Units per Acre (R 4-8). To accommodate residential development at densities ranging from a minimum of four (4) units per acre to a maximum of eight (8) units per acre; to allow sufficient residential density to facilitate effective mass transit service; and to help maintain the character of established neighborhoods.

5.    Residential 6-12 Units per Acre (R 6-12). To accommodate residential development, at densities between six (6) and twelve (12) units per acre, in locations with frequent mass transit service (existing or planned). This includes areas along or near (e.g., within one-fourth (¼) mile) arterial and major collector streets. Parcels located in the High Density Corridor Transition Area are allowed fourplex housing types.

6.    Mixed Residential 7-13 Units per Acre (MR 7-13). To accommodate a compatible mixture of houses, duplexes, townhouses, and apartments in integrated developments with densities averaging between seven (7) and thirteen (13) units per acre; to provide a broad range of housing opportunities; to provide a variety of housing types and styles; and to provide for development with a density and configuration that facilitates effective and efficient mass transit service. This district generally consists of parcels along arterial or collector streets of sufficient size to enable development of a variety of housing types.

7.    Mixed Residential 10-18 Units per Acre (MR 10-18). To accommodate a compatible mixture of single-family and multifamily dwellings in integrated developments close to major shopping and/or employment areas (at densities averaging between ten (10) and eighteen (18) units per acre); to provide a variety of housing types and styles; to provide for development with a density and configuration that facilitates effective and efficient mass transit service; to provide opportunities for people to live close to work and shopping in order to reduce the number and length of automobile trips; and to enable provision of affordable housing.

8.    Residential Multifamily - 18 Units per Acre (RM-18). To accommodate predominantly multifamily housing, at an average maximum density of eighteen (18) units per acre, along or near (e.g., one-fourth (¼) mile) arterial or major collector streets where such development can be arranged and designed to be compatible with adjoining uses; to provide for development with a density and configuration that facilitates effective and efficient mass transit service; and to enable provision of affordable housing.

9.    Residential Multifamily - 24 Units per Acre (RM-24). To accommodate predominantly multifamily housing, at an average maximum density of twenty-four (24) units per acre, in locations close (e.g., one-fourth (¼) mile) to major employment and/or shopping areas; to provide for development with a density and configuration that facilities effective and efficient mass transit service; and to enable provision of affordable housing.

10.    Residential Multifamily - High Rise (RMH). To accommodate multifamily housing in multistory structures near the State Capitol Campus; to provide opportunities for people to live close to work, shopping, services and a major mass transit hub; to create a desirable living environment for residents of the district; and to ensure that new high rise buildings incorporate features which reduce their perceived scale and allow sunlight to reach street level.

11.    Residential Mixed Use (RMU). To accommodate attractive, high-density housing, pedestrian oriented commercial and mixed-use development which reinforces downtown’s historic character; to provide for coordinated pedestrian amenities; to preserve viable downtown housing; to enable businesses to locate within walking distance of residences and offices; to provide a transition between commercial and residential districts; and to require new high rise buildings to incorporate features which reduce their perceived scale and allow sunlight to reach street level.

A.    ACCESSORY DWELLING UNITS (ADU).

Accessory dwelling units (ADU) are permitted in all residential districts subject to the following requirements:

1.    Number. One (1) ADU shall be allowed per residential lot in conjunction with any detached single-family structure. (See OMC 18.04.080(A)(3) regarding ADUs in new subdivisions.)

2.    Location. The ADU shall be permitted as a second dwelling unit added to, created within, or detached from the original dwelling. The ADU shall be oriented in a way that maintains, to the extent practical, the privacy of residents in adjoining dwellings. (See chapter 18.100 OMC, Design Review, and chapter 18.175 OMC, Infill and Other Residential.)

3.    Size. The ADU shall have a gross floor area of no more than 850 square feet. Covered porches or patios (or similar covered spaces) do not count toward the gross floor area of the ADU but are limited to a total of 120 square feet in size for each ADU and may not be enclosed.

4.    Accessory Dwelling Units may be attached to accessory structures such as a garage or shop building. In such circumstances, the ADU may be up to 850 square feet in size and the accessory structure may be up to 800 square feet in size (or larger if the underlying zoning district allows or a conditional use permit for a large garage has been approved).

5.    Occupancy. No more than one family (as defined in chapter 18.02 OMC, Definitions) shall be allowed to occupy an ADU.

6.    Existing ADUs. Accessory dwellings created prior to the enactment of these regulations, June 19, 1995, may be approved subject to applicable requirements. If the owner of an existing unauthorized ADU applies to make the unit legal, but cannot meet all of the standards, the owner will be allowed a "grace period" of six months from date of application to comply with applicable standards. However, where health and safety are an issue, the Building Official will determine when the necessary modifications must be made. If the owner cannot meet the standards, the unauthorized accessory unit must be removed or its use as a dwelling must be suspended.

7.    Deviation From Requirements. The Director or the Director’s designee may allow deviation from the requirements of this section (OMC 18.04.060(A)) as follows:

a.    To allow use of the entirety of a single floor in a dwelling constructed two or more years prior to the date of application in order to efficiently use all floor area; and

b.    To enable ADUs to be established in structures constructed prior to June 19, 1995, which are located in rear or side setbacks, provided that Building Code requirements and the Development Standards contained in OMC 18.04.080 are met. [NOTE: See chapter 18.100 OMC, Design Review, and chapter 18.175 OMC, Infill and Other Residential for applicable design guidelines.]

B.    ACCESSORY STRUCTURES.

Accessory structures are detached structures and are permitted in all residential districts subject to the following requirements:

1.    Time of Establishment. Accessory structures shall not be built prior to commencing construction of the main building on the lot. However, lots may be created which contain an accessory structure (without an associated primary use) constructed prior to submission of the subdivision application.

2.    Subordinance to Primary Use. Accessory structures shall be clearly incidental and subordinate to the use of the lot (e.g., structures used for storage of personal property or the pursuit of hobbies) or used for agricultural purposes. In residential districts with a maximum density of twelve units or less per acre each accessory structure shall not exceed 800 square feet in size, except for:

ii.    A roof type or pitch similar to the primary use;

c.    Detached garages or carports exceeding 1,200 square feet per dwelling unit may be permitted as conditional uses in the districts specified in Table 4.01 provided that they will not be adverse to the public interest and are compatible with the surrounding neighborhood. The criteria for garages/carports outlined above in OMC 18.04.060(B)(3) and OMC 18.175.060 must be met. The approval authority shall establish a maximum size for garages receiving conditional use approval. See OMC 18.04.080.

4.    See OMC 18.04.060(P)(4) regarding accessory structures in mobile home/manufactured home parks.

C.    ANIMALS/PETS.

Pets and other animals are allowed in all residential districts subject to the following requirements:

1.    Traditional Pets. No more than a total of three traditional pets, such as dogs and cats, as well as potbelly pigs, four months of age or older, shall be permitted per dwelling unit. Song birds or other traditional pet birds (e.g., parrots) are permitted. The keeping of racing and performing pigeons is permitted as a conditional use. (Traditional pets are defined as a species of animals which can be housebroken, or walked on a leash, or are frequently, but not necessarily, housed within a residence and are neither obnoxious nor a public safety or health threat.)

2.    Fowl.

a.    Lots one acre or less are allowed up to five ducks or female chickens. Lots greater than one acre are allowed one additional duck or female chicken for every additional one thousand square feet of lot area beyond one acre, up to ten ducks or female chickens.

2.    Accessory Use. A child day care center shall be considered an accessory use if it is sited on the premises of a community service use, such as a private or public school, grange, place of worship, community center, library, or similar adult gathering place and it is associated with that activity. Child care facilities for the exclusive use of employees of a business or public facility shall also be allowed as an accessory use of the business or facility. Prior to initiating operation of a child day care center, the operator must register with the City as specified in Subsection 1.

3.    Conditional Use. Child day care centers are allowed as a conditional use in the R-4, R 4-8, R 6-12 and MR 7-13 districts, subject to the requirements contained in Subsection A, and the following standard:

No structural or decorative alteration is permitted which would alter the residential character of an existing residential structure used as a child day care center.

At least one (1) common structure shall contain a dining room and kitchen large enough to serve at least fifty percent (50%) of the development’s residents at a time based upon occupancy of one (1) person per bedroom, and at least one (1) of the following: a children’s day care center, mail boxes for a majority of the residents, recreational facilities (such as pool tables or exercise equipment), laundry facilities, or a meeting room available for the use of all residents.

b.    Location. Common structures may be located in all developable portions of the site (e.g., excluding critical areas and their associated buffers and required building setback areas). However, within forty (40) feet of the site’s perimeter or a public street extending through the site, no more than two (2) common or accessory structures may be contiguous to one another (i.e., uninterrupted by a dwelling or a landscaped open space with no dimension less than forty (40) feet). This requirement does not apply to structures which would not be visible from the site’s perimeter or through streets (e.g., due to topography or vegetation) or which adjoin undevelopable property (e.g., critical areas) which will separate proposed structures by at least forty (40) feet from existing and potential dwelling sites. In no case shall more than fifty percent (50%) of any street frontage be occupied by common and/or accessory structures.

2.    Business Uses. Co-housing developments may contain business uses allowed as home occupations (see Section 18.04.060.L) in structures other than residential dwellings, subject to the conditions below:

a.    The total building square footage devoted to business uses in the entire development shall not exceed the rate of five hundred (500) square feet per dwelling unit.

d.    Each business located in a co-housing development may employ a maximum of two (2) people who do not reside in the development. This limitation does not apply to seasonal agricultural employees.

e.    Business uses shall not emit noise, pollutants, waste products, or create impacts which would pose a nuisance or health risk for the occupants of abutting properties.

3.    Dwelling Units. Dwelling units in co-housing developments shall only be required to contain minimal kitchen facilities (e.g., a sink and stove or hot plate), consistent with the Uniform Building Code, provided that a common structure provides a fully equipped kitchen (e.g., containing a stove, refrigerator, and sink) and dining area available to all residents of the development.

4.    Approval Process. Applications for co-housing projects shall be processed pursuant to OMC 18.56.

5.    Common Areas. A note shall be added to the plat or site plan, as applicable, which establishes common areas and precludes their conversion to another use. (See OMC 18.100, Design Review, for applicable design guidelines.)

Dwellings on individual lots are subject to the applicable setback standards specified in Table 4.04 or 6.01.

(See OMC 18.100, Design Review, for applicable design guidelines.)

G.    COMMERCIAL GREENHOUSES, NURSERIES AND BULB FARMS.

As a condition of approval, applicants for commercial greenhouses, nurseries or bulb farms shall demonstrate to the satisfaction of the Hearing Examiner that said development will not pose a significant nuisance for residents of the surrounding neighborhood.

Crisis intervention services do not require a public hearing by the Hearing Examiner due to the need for location confidentiality. Applications for such facilities will be reviewed administratively and are allowed subject to the provisions of OMC 18.70.180, Conditional Uses, upon licensing of the proposed facility by the State.

J.    EXISTING USES.

Duplexes, parking lots (which are the primary use of the property), and drive-in and drive-through businesses which were legally established prior to June 19, 1995 are allowed as permitted uses in the districts specified in Table 4.01. Existing mineral extraction operations, veterinary clinics, and stables which were legally established prior to June 19, 1995 are allowed as conditional uses in the districts specified in Table 4.01. Such uses shall be treated the same as other allowed uses, consistent with applicable regulations and conditional use requirements. Other existing uses made nonconforming by this code are subject to the requirements of Chapter 18.37, Nonconforming Buildings and Uses.

K.    GROUP HOMES. Group homes are subject to the following requirements.

1.    License. Authorization for group homes is subject to the issuance of a license and/or certification by all appropriate local, state, and/or federal agencies.

L.    HOME OCCUPATIONS.

The purpose of the home occupation provisions is to allow for the use of a residential structure for a non-residential use which is clearly an accessory use to the residential use and does not change the residential character of the neighborhood. Home occupations meeting the below requirements are allowed in any district in which residential uses are permitted.

1.    Review. Prior to both initial occupancy and issuance of any business license, the business operator or the operator’s agent shall certify that the home occupation will conform with the applicable requirements.

2.    General Standards. The following are the general requirements for home occupations. Also see specific standards for family child care homes, adult day care homes, bed and breakfast houses, and counseling.

a.    Home occupations must be conducted within the principal residence of the permit holder, or within an accessory structure on the same property. Permit holders shall provide evidence thereof through such means as voter registration, driver’s license, tax statement, or other evidence of residency and sign a notarized affidavit attesting to their principal residence at the site.

b.    Home occupations are subject to inspections by City staff insofar as permitted by law. Permit holders shall execute a notarized affidavit agreeing to allow appropriate City staff the ability to conduct an inspection of the residence, after reasonable notice is given, to determine compliance with the home occupation permit.

The home occupation permit shall list the names of each resident who is employed by the business. Furthermore, the residence shall not be used as a place of congregation for work that occurs off the premises. This limitation shall not apply to short-term rental – homestays or properties abutting the west side of the 300 and 400 blocks of West Bay Drive Northwest.

d.    Home occupations shall occupy not more than twenty-five (25) percent of the total floor area of the dwelling or five hundred (500) square feet per dwelling unit, whichever is less; provided, however, that properties abutting the west side of the 300 and 400 blocks of West Bay Drive Northwest shall occupy not more than fifty percent (50%) of the total floor area of the dwelling or one thousand five hundred (1,500) square feet per dwelling unit, whichever is less. This limitation does not apply to family child care homes, adult day care homes, elder care homes, short-term rental – homestays, or bed and breakfast houses.

e.    The residential character of the lot and dwelling shall be maintained. The occupation shall be conducted entirely within a dwelling and/or accessory building by the occupant of the dwelling. A carport shall not be used for home occupations, except for parking. There shall be no structural alteration nor any exterior modification of the structure in order to accommodate the occupation.

f.    The occupation shall be conducted in such a manner as to give minimal outward appearance of a business, in the ordinary meaning of the term, that would infringe upon the right of the neighboring residents to enjoy peaceful occupancy of their homes.

g.    Except for adult daycare, child daycare, and bed and breakfast businesses, and short-term rental – homestays, the hours of operation, as related to customer or client visitations, shall be limited to no earlier than 7:00 a.m. and no later than 9:00 p.m.

j.    Home occupations shall emit no noise, vibration, smoke, dust, odor, heat, glare, fumes, electrical interference, pollutants or waste products detrimental to the environment, public safety or neighborhood, beyond those normally emanating from residential uses.

k.    Home occupations shall comply with all applicable local, state or federal regulations. Requirements or permission granted or implied by this section shall not be construed as an exemption from such regulations.

l.    A home occupation permit issued to one (1) person residing in the dwelling shall not be transferable to any other person, nor shall a home occupation permit be valid at any address other than the one appearing on the permit.

m.    Any person engaging in a home occupation shall register as a business under Chapter 5.04 of the Olympia Municipal Code, and shall be subject to the Business and Occupation Tax levied by the Olympia Municipal Code.

n.    The applicant shall demonstrate compliance with all City and State licensing requirements, including those pertaining to building, fire safety, and health codes.

o.    Parking of customer, employee, or client vehicles shall not create a hazard or unusual congestion. No more than two (2) off-street parking stalls shall be provided in addition to any required for the residence. A driveway may be used as off-street parking. Except for commercial type postal carriers, traffic generated by the home occupation shall not exceed two (2) commercial vehicles per week.

2.    The applicant shall submit proof of compliance with applicable state requirements (e.g., a license) as a condition of approval.

N.    LARGE MULTIFAMILY HOUSING PROJECTS.

To ensure that large multifamily housing projects provide a transition to adjoining lower density development, multifamily projects shall be subject to the following requirements:

1.    Mix of Dwelling Types.

a.    In the RM-18 and RMU districts, no more than seventy (70) percent of the total housing units on sites of five (5) or more acres shall be of a single dwelling type (e.g., detached single-family units, duplexes, triplexes, multi-story apartment buildings, or townhouses).

b.    Multifamily housing projects in the RM-18 or RMU districts on sites of five (5) or more acres, which abut an existing or approved multifamily development of five (5) or more acres, shall contain a mix of dwelling types such that no more than eighty (80) percent of the total units in both projects (combined) are of one (1) dwelling type. The Director (or Hearing Examiner if applicable) shall grant an exception to this requirement if the Director determines that topography, permanent buffers, or other site features will sufficiently distinguish the developments.

2.    Transitional Housing Types. In the RM-18, MR 7-13 and MR 10-18 districts detached single-family houses or duplexes shall be located along the perimeter (i.e., to the depth of one (1) lot) of multifamily housing projects over five (5) acres in size which are directly across the street and visible from existing detached single-family houses. Townhouses, duplexes, or detached houses shall be located along the boundary of multifamily housing sites over five (5) acres in size which adjoin, but do not directly face, existing detached single-family housing (e.g., back to back or side to side). The Director (or Hearing Examiner) may allow exceptions to these requirements where existing or proposed landscaping, screening, or buffers provide an effective transition between the uses. (See Chapters 18.170 Multi-Family Residential Design Guidelines and 18.36.140 Residential Landscape requirements.)

O.    MANUFACTURED HOMES.

A manufactured home is allowed in all zoning districts that allow single family residences, if the home is a new, designated manufactured home (See OMC 18.02.180.D, Definitions), and meets the following criteria:

18.04.080 Residential districts development standards Revised 11/23

Table 4.04 identifies the basic standards for development in each residential district contained in this chapter. The sections referenced in Table 4.04 refer to the list of additional regulations below.

A.    Maximum Housing Densities.

1.    Calculation of Maximum Density.

a.    The maximum housing densities specified in Table 4.04 are based on the total area of the entire site, including associated and/or previously dedicated right-of-way, but not including streams, wetlands, landslide hazard areas, "important habitat areas," and "important riparian areas" and land to be dedicated or sold for public parks, schools, or similar non-residential uses.

b.    Convalescent homes. Convalescent homes and nursing homes containing dwelling units which rely on shared cooking/dining facilities count as one dwelling unit for purposes of the maximum density calculation. Independent dwelling units (i.e., containing a bed, bathroom and a kitchen with a sink, stove, and refrigerator) in convalescent/nursing homes, however, are counted as individual dwelling units in the density calculation. The density for a site or parcel containing a convalescent/nursing home which is part of a larger project is calculated separately from other portions of the site under development (i.e., density may not be transferred from a site occupied by a nursing home to another portion of the development).

2.    Mixed Residential and Multifamily Districts. The maximum housing densities shown in Table 4.04 refer to the maximum density of each project. Projects within multiple districts must conform with the density for the portion in each district.

3.    Accessory Dwelling Units. Accessory dwelling units built on infill lots are not subject to the maximum density limits specified in Table 4.04. In addition, accessory units built on a maximum of 20 percent of a subdivision’s lots prior to the time the primary unit on the lot is initially sold are not subject to the maximum density limitations.

4.    Density Bonuses. The maximum housing densities identified in Table 4.04 may be increased and authorized by the Director or by the hearing examiner as noted below, provided, however, that in the R 4-8 District, TDRs must be obtained (see OMC 18.04.080(A)(5)):

a.    Restoration of Critical Areas. At the request of the applicant, the Hearing Examiner may grant a density bonus of up to 20 percent for sites on which damaged or degraded wetlands or stream corridors (e.g., streams and stream banks within the outer limits of any required buffer) will be restored and maintained according to specifications approved by the City. A Request for this density bonus must accompany the land use application and is a Type III application pursuant to OMC 18.70.040, except as provided in OMC 18.04.080(A)(4)(b-d). Prior to taking action on a request for this density bonus, the Hearing Examiner shall consider the public’s comments, the expected public benefit that would be derived from such restoration, the probable net effect of the restoration, and the increased density on the site, the relative cost of the restoration and the value of the increased density, and the potential impact of increased density on surrounding land uses, traffic, infrastructure, schools, and parks. The City may require the applicant to provide an estimate of the cost of the proposed restoration and other information as necessary to make this determination. This bonus does not apply to site features which were damaged in the course of a current project (e.g., under an active permit) or as a result of an illegal or intentional action by the current property owner or their representative.

b.    Cottage housing. Cottage housing projects receive a 20 percent density bonus.

c.    Townhouses. Townhouses receive a 15 percent density bonus in the R 4-8 and R 6-12 districts.

d.    Low income housing. A density bonus is granted for low income housing (see Section 18.02.180, Definitions) at the rate of one additional housing unit allowed for each unit of low income housing provided, up to a maximum of a 20 percent bonus.

The applicant shall submit to the Department a document approved by the City Attorney stating that the low income housing which is the basis for the density bonus will remain for a period of at least 20 years from the date the final inspection is conducted by the Building Official. This document must be recorded, at the applicant’s expense, at the Thurston County Auditor’s Office as part of the chain of title of the affected parcels.

5.    Transfer of Development Rights. Development Rights must be obtained from an eligible property owner in a Thurston County Transfer of Developments Rights (TDR) Sending Zone in order to develop above eight units per acre in an R 4-8 District. However, this requirement does not apply to density bonuses granted in accordance with OMC 18.04.080(4). With one TDR credit, a density of nine units per acre can be achieved in the Residential 4-8 District.

6.    City staff will review residential permitting in areas designated as Low Density Neighborhood in the adopted Comprehensive Plan Future Land Use Map on an annual basis to review the achieved density. If achieved density approaches or exceeds the density anticipated in the comprehensive plan, the City will make revisions as needed to maintain consistency between the Comprehensive Plan and development regulations.

B.    Minimum Housing Densities

1.    Calculation of Minimum Density.

a.    (Note: Table 5.05 in Section 18.05.) The total area of the entire site shall be included in the minimum density calculation except streams, wetlands, landslide hazard areas, floodplains, "important habitat areas," and "important riparian areas" and their associated buffers; tracts accommodating stormwater facilities required in compliance with the Drainage Manual tracts provided for trees pursuant to the Tree Protection and Replacement Ordinance; existing, opened street rights-of-way; and land to be sold or dedicated to the public in fee (e.g., school sites and public parks, but not street rights-of-way to be dedicated as part of the proposed development).

b.    All dwelling units in convalescent homes/nursing homes and accessory dwelling units count toward the minimum density required for the site by Table 4.04.

2.    Average Density. A housing project may contain a variety of housing densities (consistent with Table 4.04) provided that the average density for the entire development (e.g., all of the property subject to a single subdivision, site plan, or PRD approval) is neither less than the minimum density nor more than the maximum average density established for the applicable district in Table 4.04.

3.    Allowance for Site Constraints. At the request of the applicant, the Director may reduce the minimum density required in Table 4.04, to the extent the Director deems warranted, to accommodate site constraints which make development at the required minimum density impractical or inconsistent with the purposes of this Article. Factors which may warrant a density reduction include poor soil drainage, the presence of springs, topography exceeding twenty (20) percent slope, rock outcrops, sensitive aquifers used as a public water source or wellhead protection areas). As a condition of granting a density reduction, the applicant must demonstrate that the minimum density cannot be achieved by clustering the housing on the buildable portions of the site (see Section 18.04.080(F)). The Director may also authorize a reduction in the minimum density requirements, if necessary, to enable development of small (i.e., less than six (6) acres in size), oddly shaped, or partially developed parcels if the site’s configuration or constraints (e.g., existing structures) preclude development at the minimum density specific in Table 4.04. Also see Subsection (E), Developments without Sewer Service, below.

4.    Allowance for Transitional Housing and Mixed Residential Projects. The Director may reduce the minimum densities required by Table 4.04 to enable provision of lower density housing along the perimeter of multifamily housing projects, as required by Section 18.04.060(14) or as necessary to accommodate the mix of housing types required by Section 18.04.060(Q)(1).

C.    Minimum Lot Size.

1.    Nonresidential Uses. The minimum lot size for non-residential uses (e.g., places of worship and schools) is larger than the minimum lot size identified in Table 4.04. Refer to Table 4.01 and Section 18.04.060 for regulations pertaining to non-residential uses. Also see Section 18.04.060(K) for the lot size requirements for group homes.

2.    Undersized Lots. Undersized lots shall qualify as a building site if such lots were recorded prior to June 19, 1995 or they were approved as part of a Planned Residential Development, Master Planned Development (See Chapter 18.56) or clustered housing development, consistent with Section 18.04.080(F); provided, however, that any lot of record which does not comply with the width requirements of this code shall not be constructed upon unless (1) it is legally combined with undeveloped contiguous land in the same ownership which in combination create a lot of the size specified in Table 4.04 (or as modified by other provisions of this Article); or (2) it is approved by Design Review Board Staff, who shall perform an architectural review of the proposal for compliance with the criteria specified in Chapter 18.100, Design Review.

3.    Clustered Lots. Lot sizes may be reduced by up to twenty (20) percent consistent with Section 18.04.080(F), Clustered Housing.

4.    That portion of any lot which is less than thirty (30) feet in width shall not be considered part of the minimum lot area required in Table 4.04, unless such area conforms with the minimum lot width, e.g., townhouse lot.

D.    Transitional Lots.

1.    Lot Size. The square footage and width of lots in developments larger than five (5) acres located in the MR 7-13, MR 10-18, or RM-18 districts, which immediately abut an R-4, R 4-8 or R 6-12 district, shall be no less than eighty-five (85) percent of the minimum lot size and width required in the adjoining lower density district.

2.    Setbacks. The minimum rear yard building setback for lots in the MR 7-13, MR 10-18, and RM-18 districts which share a rear property line with a parcel in an R4, R 4-8, or R 6-12 district shall be no less than the setback required for the adjoining lower density district.

E.    Developments without Sewer Service. Residential developments which rely on on-site sewage disposal or water systems are subject to the following requirements:

1.    Subdivisions.

a.    Subdivisions, planned residential developments (PRD) and Master Planned Developments (see Chapter 18.56) which rely on on-site sewage disposal shall cluster the lots on a portion of the site and create a reserve tract which will not be available for subdivision or other development until municipal sewer and water are available.

The development shall be of a design and density (consistent with Environmental Health and other applicable regulations) so that the initial clustered lots and the subsequently subdivided reserve tract ultimately attain at least the minimum density specified for the district in Table 4.04. (Unless the Director determines that fewer lots are required, consistent with Section 18.04.080(B), Minimum Housing Densities.)

b.    Approval of clustered subdivisions, short subdivisions, binding site plans, or PRDs relying on on-site sewage disposal shall be contingent upon approval of a future development plan which demonstrates that the reserve tract can be subdivided to create sufficient lots to comply with Subsection (1) above. Such plans shall depict a schematic lot layout, the approximate location of utility easements, and potential street access, consistent with the transportation policies and Map 6-3 contained in Chapter 6 of the Comprehensive Plan for Olympia and the Olympia Growth Area, 1994 (and as hereafter amended). Future development plans shall not be required to be stamped by an engineer or surveyor. (The purpose of the plan is to show that the undeveloped portion of the site can be ultimately developed at urban density, not to limit future development to a specific development scheme. However, the initial subdivision or site development must be consistent with the future development plan.)

2.    Individual Lots.

a.    Issuance of building permits for dwellings proposed for parcels five (5) or more acres in size without sewer service shall be contingent upon approval of a future development plan for the parcel. Such plans shall demonstrate, consistent with 1.b. above, how the parcel can be potentially developed at the minimum density established for the district (see Table 4.04) when public sewer and water are available. While this plan will not bind future development, the initial development, including the septic system location, must be consistent with it.

b.    Issuance of building permits for dwellings without sewer service on parcels between one (1) and five (5) acres in size shall be contingent upon approval of a building site plan or future development plan which demonstrates that the parcel can potentially accommodate one (1) or more additional houses in the future. While future development will not be bound by this plan, the initial development shall be consistent with it. Developers of such lots shall locate individual or community sewage disposal systems, to the extent possible, where they can be efficiently converted to a public sewage collection system in the future.

F.    Clustered Housing.

1.    Mandatory Clustering. The Director or Hearing Examiner may require that the housing units allowed for a site be clustered on a portion of the site in order to protect ground water used as a public water source (e.g., wellhead protection areas), to enable retention of windfirm trees (which are appropriate to the site and designated for retention, consistent with Chapter 16.60, Tree Protection and Replacement, OMC), to accommodate urban trails identified on Map 7-1 of the Comprehensive Plan, to preserve scenic vistas pursuant to Sections 18.20.070, View Preservation and 18.50.100, Scenic Vistas, or to enable creation of buffers between incompatible uses (also see Chapter 18.36, Landscaping and Screening).

The Director or Hearing Examiner may allow up to a twenty (20) percent reduction in lot dimensions, sizes and setback requirements, consistent with the Uniform Building Code, to facilitate the clustering of the permitted number of dwelling units on the site. The required clustering shall not result in fewer lots than would otherwise be permitted on the site (at the minimum density specified in Table 4.04), without written authorization by the applicant.

2.    Optional Clustering. Applicants for housing projects may request up to twenty (20) percent reduction in lot sizes, dimensions, and building setback requirements in order to cluster housing and retain land serving the purposes listed in a. above; or to avoid development on slopes steeper than twenty (20) percent; or to preserve natural site features such as rock outcrops; or otherwise enable land to be made available for public or private open space. Applicants proposing to place sixty-five (65) percent or more of a development site within a tree or vegetation protection or critical areas tract or tracts (see OMC chapter 16.60 and section 18.32.140) and not exceed 10% overall impervious coverage may request approval of housing forms not otherwise permitted in the zoning district so long as the number of resulting residential units does not exceed the standard maximum by more than twenty (20) percent. Such alternative housing forms may exceed height and story limits otherwise applicable in the district, except for height and story limits specifically intended to soften transitions between zoning districts. For example, three-story multi-family housing may be approved in a two-story single-family housing district. The Director or Hearing Examiner, as applicable, may grant such requests only if the Director or Hearing Examiner determines that the development would not have a significant adverse impact on public facilities and surrounding land uses.

G.    Lot Width.

1.    Measurement. The minimum lot width required by Table 4.04 shall be measured between the side lot lines at the point of intersection with the minimum front setback line.

H.    Setbacks.

1.    Measurement. The required setback area shall be measured from the outermost edge of the building foundation to the closest point on the applicable lot line.

2.    Reduced Front Yard Setbacks. Front yard setbacks in the R-4, R 4-8, R 6-12, MR 7-13 and MR 10-18 districts may be reduced to a minimum of ten (10) feet under the following conditions:

a.    When garage or parking lot access is from the rear of the lot;

b.    When the garage is located at least ten (10) feet behind the front facade of the primary structure on the lot; or

c.    When the driveway will be aligned to provide at least a twenty (20) foot long parking space between the sidewalk edge (closest to lot) and the garage. (See OMC 18.100 Design Review and OMC 18.175 Infill and Other Residential.)

FIGURE 4-3

3.    Rear Yard Setbacks. See OMC 18.04.080(H)(5), Encroachments into Setbacks, Section 18.04.080(D)(2), Transitional Lots, and Table 4.04.

4.    Side Yard Setbacks.

a.    Reduced side yard setbacks. A side yard building setback is not required for a lot, provided it meets the following conditions:

i.    Provision for reduced or zero setbacks shall specifically appear upon the face of a final short or long plat. Such plat shall provide that the minimum distance between residences will be six (6) feet. If the distance between a proposed dwelling and a property line is less than three (3) feet, the applicant shall provide evidence of a maintenance easement, at least three (3) feet in width, which provides sufficient access for the owner of the dwelling to maintain the applicable exterior wall and roof of the dwelling. (Except as expressly provided, any reduced side yard provision appearing on a final plat shall withstand later amendments of this Title and shall be considered conforming.)

ii.    Side yard setbacks shall not be less than five (5) feet along a property line adjoining a lot which is not developed or approved for reduced setbacks (e.g., a conventional lot with two (2) five (5) foot wide side yard setbacks). Side yard setbacks shall not be less than ten (10) feet along property lines which abut a public rights-of-way.

b.    The minimum side yard setback from bikepaths and walkways shall comply with the side yard setback from the lot line as specified for the district in Table 4.04.

5.    Encroachment Into Setbacks. The buildings and projections listed below shall be allowed outside of utility, access or other easements. See OMC 18.04.080(H)(5) for additional exceptions.

a.    Except for Accessory Dwelling Units, any accessory structures may be located in a required rear yard and/or in the rear twenty (20) feet of a required interior side yard; however, if a garage entrance faces a rear or side property line, it shall be setback at least ten (10) feet from that property line. Accessory dwelling units may not encroach into required side yard setbacks. Accessory dwelling units may encroach into rear yards however, if the rear yard does not abut an alley, the accessory unit must be set back ten (10) feet from the rear property line. Further, any garage attached to any accessory dwelling unit shall conform with this Section.

b.    Up to fifty percent (50%) of a rear yards width may be occupied by a dwelling (primary residence or ADU) provided that the structure (foundation) is located at least ten (10) feet from the rear property line. For purposes of this section the rear yards width shall be measured in a straight line between the side property lines at the point of intersection with the rear property line.

Figure 4-4a

c.    Townhouse garages may share a common rear property line provided that access for interior lots is from a single common driveway to not more than one public street entrance.

6.    Front yard setbacks for through lots. A through lot has two (2) front lot lines parallel or approximately parallel to each other. The front yard setback shall apply to each front lot line, except the Director may designate one (1) of the front lot lines as a rear lot line, provided the following criteria are met:

a.    Orientation of the lot or structure shall be considered; and

b.    At least sixty percent (60%) of the lots or structures within the neighborhood block, or area being considered, are oriented in a similar direction away from the lot line being designated as a rear lot line.

I.    Height.

1.    Roof Projections. The following structures may exceed the height limits specified for the district in Table 4.04 by 18 feet, provided that such structures do not contain floor space: roof structures housing elevators, stairways, tanks, ventilating fans or similar equipment required to operate and maintain the building; fire or parapet walls; skylights; towers; flagpoles; chimneys; smoke stacks; wireless masts; television antennas; steeples; and similar structures. Use of this provision must be kept to the minimum amount of space needed to accommodate the allowed roof projection. For the UR zoning district, see view protection provisions in OMC 18.04.080(I)(3) below for additional parameters.

FIGURE 4

2.    RMU District Height Regulations.

a.    Base building heights. The base building heights allowed in the RMU District are specified in Figure 4-5.

b.    Sculptured building tops. The following sculptured building top regulations apply only where the permitted building height is 60 feet.

Buildings with sculptured tops may exceed the permitted height (60 feet) by two building stories if they meet the following conditions:

i.    The gross floor area of all of sculptured stories is at least one-third less than the gross floor area of the first floor of the building; and

ii.    The roof form is sculptured (e.g., pitched roof, hip roof, dome, chateau roof, tower, turret, pediment, dormers, or other similar form); and

iii.    The added two stories are setback from the street wall at least eight feet; and

iv.    The roof structure is designed to hide all mechanical and communications equipment located there.

3.    UR District Height Regulations. The building heights allowed in the UR District are specified in Figure 4-5 and 45-A. Also see 18.10.060, Capitol Height District.

a.    Roof Projection Allowances: If the City determines that the proposed development is located on a site in the UR zone where use of the roof projection allowance is proposed and that it may impact a protected landmark view (as listed in Appendix B of the Land Use and Urban Design chapter of the Comprehensive Plan), a view analysis must be submitted that demonstrates, as determined by the city, that the proposed roof projection will not block or substantially impact the protected view from its designated observation point in order to make use of the roof projection allowances of OMC 18.04.080(I).

4.    R4-8 District Height Regulations. Existing State Community College Education Facilities. A maximum 60’ building height is allowed with a 100’ setback from adjacent residentially zoned property.

5.    Places of Worship. Places of worship may exceed the height limits specified in Table 4.04, except in the State Capitol Group Height District, provided that the side yard width equals at least fifty (50) percent of the building’s proposed height (including spires and towers).

6.    Radio, Television and other Communication Towers. The height of radio, television, and other communication towers may exceed the maximum building height allowed in the district, subject to approval of the Decision Authority consistent with OMC 18.04.060(W) and 18.04.060 (X) and processed as a type II application.

7.    Tall Buildings in the MR Districts. Buildings between 35 and 45 feet in height are permitted in the MR 7-13 and MR 10-18 districts, subject to compliance with the following requirements:

FIGURE 4-5

FIGURE 4-5A

a.    The proposed building will not be located within 100 feet of the boundary of the property under development (this may include several parcels under a single development proposal). Exceptions to this requirement will be granted where topography, stands of trees (deemed appropriate for retention by the City, consistent with chapter 16.60 OMC, Tree Protection and Replacement), or other site features block the visibility of the section of the building above 35 feet in height from existing or potential residential areas (zoned and available for residential use) adjoining the site; and

b.    Existing evergreen trees, which the City deems are appropriate to the site (e.g., which do not pose significant risks for proposed site improvements or public safety, consistent with chapter 16.60 OMC, Tree Protection and Replacement) are retained where possible to help screen the building from the view of residents of dwellings abutting the property.

8.    Water Towers. Water towers may exceed the height limits specified in Table 4.04.

[NOTE: Refer to Article III, Height Overlay Districts, for additional restrictions.]

J.    Private and Common Open Space.

1.    Development of Open Space. Open space (e.g., private yard areas and common open space) required by Table 4.04 shall be devoted to undisturbed native vegetation, landscaping (consistent with Chapter 18.36, Landscaping and Screening), and/or outdoor recreational facilities. Driveways, loading areas, maneuvering space and parking lots shall not be considered open space. Required open space shall not be covered with impervious surfaces, except for stoops, porches, or balconies, walkways, tennis courts, swimming pools, or similar uses which require an impervious surface. Up to a five percent (5%) increase in impervious surface coverage may be allowed to accommodate such hard surfaced facilities. Also see Chapter 16.60 Tree, Soil and Native Vegetation Protection and Replacement.

2.    Cottage Housing Developments. Cottage housing developments shall provide open space as follows:

a.    A minimum of two hundred (200) square feet of private, contiguous, usable, open space shall be provided adjacent to each dwelling unit. No dimension of this open space area shall be less than ten (10) feet provided that at least fifty percent (50%) of such open space may be combined with soil and vegetation protection area standards.

b.    A minimum of fifteen hundred (1,500) square feet or two hundred (200) square feet per unit, whichever is more, shall be provided in common open space (i.e., available for the use of all residents of the development). This open space shall be contained in a contiguous area with no dimension less than thirty (30) feet. A substantial portion of such open space shall be sufficiently level (e.g., less than five percent (5%) slope) and well drained to enable active use in summer.

3.    Mixed Density Districts. Parcels or sites accommodating multifamily housing (e.g., triplexes, fourplexes, and larger apartment buildings) in a MR 7-13 or MR 10-18 district shall contain at least thirty percent (30%) open space. At least fifty percent (50%) of such open space must be available for the common use of the residents of the multifamily housing. Such open space shall be developed consistent with Section 18.04.080(J)(1) above. This open space requirement shall be reduced to twenty percent (20%) if the multifamily housing adjoins a park, school or open space site of at least ten thousand (10,000) square feet in size. Impervious surface coverage limits specified in Table 4.04 shall be adjusted accordingly.

4.    Manufactured or Mobile Home Parks. At least five hundred (500) square feet of common open space shall be provided per dwelling unit (see Section 18.04.060(P)(8)). At least fifty percent (50%) of such open space shall comply with soil and vegetation protection area standards.

5.    Residential - 4 Chambers Basin District. Required open space for stormwater dispersion may be provided in a common area or within each individual private lot of a development. All required drainage dispersal areas shall be protected from filling and grading and all other activities which would decrease the ability of such areas to disperse and infiltrate stormwater. Side yard setback areas shall be designed to disperse roof runoff to the maximum extent practical. To qualify as a "drainage dispersal tract" (required to create lots of less than one acre) such area shall be held in common or deeded to homeowners association and otherwise conform with the requirements of stormwater tracts as set forth in the Olympia Stormwater Drainage Manual.

K.    Surface Coverage Limits:

1.    Increased Surface Coverage Limits: Non-residential uses such, as schools, parks, and places of worship, located in residential zones may increase the total amount of impervious or hard surfaces above the established maximum by up to ten percent (10%) for impervious surfaces, and twenty percent (20%) for hard surfaces, provided all of the following criteria are met:

a)    The project site is greater than one (1) acre in size.

b)    The increase is not caused by a desire for additional surface parking areas in excess of the range established in table 38.01 of OMC 18.38.100.

c)    Low impact development requirements in the Drainage Design and Erosion Control Manual are determined feasible and are implemented.

2.    Existing Surfaces: An existing lot, which was legally built under regulations applicable at the time of its building, but which exceeds current impervious or hard surface coverage limits, may be replaced within the existing lot footprint, but cannot be expanded in a way that would increase the nonconformity. Replacement of such surfaces must comply with the Drainage Design and Erosion Control Manual, including, providing stormwater control measures.

3.    Calculation Exclusions: The following are excluded from the impervious and hard surface coverage limit calculations. Note: these exclusions do not apply to calculations or requirements related to the Drainage Design and Erosion Control Manual.

a)    Ingress/egress easements serving a neighboring property;

b)    Areas excluded from the minimum lot area calculations (OMC 18.04.080(c)(4)), such as the panhandle of a flag lot;

c)    Portions of the driveway that extend beyond the required setback area when the additional length is caused by compliance with municipal code requirements, such as critical area and buffer protections.
