18.04.010 Purpose. Revised 3/21

The specific purposes of the residential districts are to:

A.    Preserve, protect, and enhance the character of the City’s different residential neighborhoods.

B.    Ensure adequate light, air, and open space for each dwelling.

C.    Ensure that the scale and design of new development and alterations to existing structures are compatible with surrounding homes and appropriate to the physical characteristics of the site and the area where the project is proposed.

D.    Provide sites for public and semi-public land uses, such as parks and public safety facilities, that will serve City residents and will complement surrounding residential development.

Additional purposes of each residential district which follow implement General Plan classifications of “Single-Family, Low Density,” “Single-Family,” “Multiple-Family, Low Density,” and “Multiple-Family, Medium Density.”

E.    RS-3 Single-Family, Low Density. This district is intended for residential densities up to three (3) units per net acre. Dwelling types may include detached single-unit housing and accessory dwelling units. In addition to single-unit homes, this district provides for uses such as small and large family child care, park and recreation facilities, and community gardens that may be appropriate in a single-family residential neighborhood.

F.    RS-6 Single-Family. This district is intended for residential densities up to six (6) units per net acre. Dwelling types may include detached single-unit housing, small lot single-unit development, duplexes, townhomes, and accessory dwelling units. This district also allows for uses such as small and large family child care, park and recreation facilities, and civic and institutional uses such as schools and places for community assembly that may be appropriate in a single-family residential neighborhood.

G.    RM-20 Multiple-Family, Low Density. This district is intended for residential densities of up to twenty (20) units per net acre developed at a scale and form that is appropriate to its neighborhood context and adjacent uses. Dwelling types include small lot single-unit development, bungalow courts, front or rear loaded townhomes, multi-unit buildings, and accessory dwelling units. This district also allows for limited uses such as small and large family day care, park and recreation facilities, and civic and institutional uses such as schools and places for community assembly that are appropriate in a low density multifamily residential environment.

H.    RM-59 Multiple-Family, Medium Density. This district is intended for residential development at densities up to fifty-nine (59) units per net acre. This density range accommodates townhomes and multi-unit buildings developed at a scale and form that is appropriate to its neighborhood context and adjacent single-family residential uses and forms. Small lot single-unit and bungalow court development is allowed where site conditions exist rendering the development type equal to or better than multi-unit or townhome development. Accessory dwelling units are also permitted in this district. In addition to residential uses, this district allows for a limited number of public and semi-public uses such as day care centers, public safety facilities, and residential care facilities that are appropriate in a medium density multifamily residential environment. (Ord. 1568 § 1 (Exh. A), 2021; Ord. 1566 (Exh. B (part)), 2020: Ord. 1537 (Exh. B (part)), 2018: Ord. 1480 (Exh. B (part)), 2015: Ord. 1438 § 4 (Exh. A (part)), 2011)

18.04.020 Land use regulations. Revised 3/21

Table 18.04.020 prescribes the land use regulations for residential districts. The regulations for each district are established by letter designations as follows:

“P” designates permitted uses.

“M” designates use classifications that are permitted after review and approval of a minor use permit by the Zoning Administrator.

“C” designates use classifications that are permitted after review and approval of a conditional use permit by the Planning Commission.

“(#)” numbers in parentheses refer to specific limitations listed at the end of the table.

“-” designates uses that are not permitted.

Use classifications are defined in Chapter 18.40, Use Classifications. In cases where a specific land use or activity is not defined, the Director shall assign the land use or activity to a classification that is substantially similar in character. Use classifications and subclassifications not listed in the table or not found to be substantially similar to the uses below are prohibited. The table also notes additional use regulations that apply to various uses. Section numbers in the right-hand column refer to other sections of this title.

FIGURE 18.04.040-I: ALLEY ACCESS

J.    Small Lot Subdivisions.

1.    Purpose. The purpose of this subsection is to provide opportunities to increase the supply of smaller dwelling units and rental housing units by allowing the creation of subdivisions with smaller lots and dwellings. It also is intended to establish design and development standards for these projects to ensure that they are compatible with the surrounding neighborhood, where the General Plan anticipates no change to existing neighborhood character.

2.    Location. A small lot subdivision may be proposed and approved on any site within the RS district where such development would be compatible with adjacent uses and the character of the area. A small lot subdivision shall not be allowed where the review authority determines that public utilities and services are inadequate or the landform is inappropriate for such development because of grading or impacts on views from adjacent lots.

3.    Development Types. Small lot subdivisions may be proposed and approved for small lot single-unit, bungalow court, and townhouse development developed according to Section 18.04.070, Residential development types.

4.    Lot Standards. The lot standards listed in Table 18.04.040-J, Small Lot Subdivision Lot Standards, apply to small lot subdivisions.

(Ord. 1537 (Exh. B (part)), 2018: Ord. 1480 (Exh. B (part)), 2015; Ord. 1438 § 4 (Exh. A (part)), 2011)

18.04.060 Supplemental regulations—RM districts.

A.    Building Entrances.

1.    Orientation. All units located along public rights-of-way must have the primary entrance facing this right-of-way. Exceptions to this requirement may be approved for projects where multiple-family housing is located on four-lane streets carrying high traffic volumes and/or streets that do not allow on-street parking. In such cases, the project may be oriented around courtyards.

2.    Projection or Recess. Building entrances must have a roofed projection (such as a porch) or recess with a minimum depth of at least five feet and a minimum horizontal area of fifty square feet. Alternative designs that create a welcoming entry feature facing the street, such as trellis or landscaped courtyard entry, may be approved by the Director.

3.    Dwelling Unit Access. Exterior entrances to units shall be in a form of individual or shared entrances at the ground floor of the building. Unit entrances above the ground floor are also permitted; however, no exterior access corridor located above the ground floor may provide access to five or more units.

B.    Building Design. Buildings shall include adequate design features to create visual variety and avoid a large-scale and bulky appearance.

1.    Building Length. The maximum dimension of any single building shall not exceed one hundred twenty-five feet.

2.    Roof Line. The roof line at each elevation shall demonstrate an offset of at least eighteen inches for each one to three units exposed on that elevation. Large, continuous roof planes are prohibited.

3.    Window Trim or Recess. Trim at least one inch in depth must be provided around all windows, or window must be recessed at least two inches from the plane of the surrounding exterior wall. For double-hung and horizontal sliding windows, at least one sash shall achieve a two-inch recess. Exceptions may be granted through the design review process to accommodate alternative window design complementary to the architectural style of the structure.

4.    Windows. Snap-in vinyl mullions between double pane glass are prohibited. If a divided light appearance is desired, mullions must be made of dimensional material projecting in front of the panes on both the inside and outside of the window.

5.    Facade Articulation. All street-facing facades shall have at least one horizontal or vertical projection or recess at least four feet in depth, or two projections or recesses at least two and one-half feet in depth, for every twenty-five horizontal feet of wall. If located on a building with two or more stories, the articulated elements must be greater than one story in height, and may be grouped rather than evenly spaced in twenty-five-foot modules. Building entrances and front porches and projections into required yards such as stoops, bays, overhangs, fireplaces, and trellises may count towards meeting this requirement.

6.    Facade Detailing and Materials. All visible building facades shall incorporate details, such as window and door trim, window recesses, cornices, changes in materials or other design elements, in an integrated composition. Each side of a building that is visible from a public right-of-way shall be designed with a complementary level of detailing and quality of materials.

7.    Building Colors. Every building shall have at least two complementary colors which demonstrate a harmonious relationship.

8.    Building Materials. All materials shall be high quality to allow for long-term durability and appearance. The exterior use of foam for trim and plywood, vinyl or aluminum as siding materials is prohibited.

9.    Transition Areas. Where new multifamily developments are built adjacent to existing lower-scaled residential development, the facade facing the existing lower-scaled residential development shall be designed to provide architectural relief and interest, while also respecting the scale of adjacent neighbors.

a.    Height. Full-height recesses, a minimum of ten feet deep, shall be provided along the facade to break the building into smaller discrete masses.

FIGURE 18.04.060-B(8)(a): MINIMUM RECESS

b.    Window and Balcony Placement. Offset windows to avoid direct sight lines into and from neighboring properties. Position balconies and other private open space so they minimize views into neighboring properties.

10.    Exceptions. Exceptions to the building design standards may be granted with approval of a conditional use permit based on the finding that adequate design features have been incorporated to create visual variety and avoid a large-scale, bulky, or monolithic appearance.

C.    Private Storage Space. Each unit shall have at least two hundred cubic feet of enclosed, weather-proofed, and lockable private storage space with a minimum horizontal dimension of four feet.

D.    Paving. Differentiated paving materials shall be used for garage aprons, entries, and pedestrian walkways. This may include, but not be limited to, textures or colors, concrete pavers, brick, or stamped concrete. The use of permeable materials to reduce runoff is strongly encouraged.

E.    Pedestrian Access. On-site pedestrian circulation and access must be provided according to the following standards:

1.    Internal Connections. A system of pedestrian walkways shall connect all buildings on a site to each other, to on-site automobile and bicycle parking areas, and to any on-site open space areas or pedestrian amenities.
