(a) 
These regulations set forth the required standards for cottage housing developments as permissible uses in the following zoning districts: R4, R6, R8-12 and MFR.
(b) 
Cottage housing allows for a higher density development than is normally allowed. This is made possible by smaller home sizes, clustered home sites, and parking and design standards.
(c) 
The intent of the cottage housing development regulations is to:
(1) 
Support the growth management goal of more efficient use of urban residential land;
(2) 
Support development of diverse housing in accordance with the Comprehensive Plan;
(3) 
Increase the variety of housing types available for smaller households;
(4) 
Provide opportunities for small, detached dwelling units within existing neighborhoods; and
(5) 
Provide opportunities for creative, diverse and high quality infill development that is compatible with existing neighborhoods.
(Ord. 798, Sec. 7 (Exh. 2), 2009; Ord. 1081, Sec. 4, 2020; Ord. 1179, Sec. 13, 2024)
An existing detached single-family dwelling that is incorporated into a cottage housing development as a residence and is nonconforming with respect to the standards of this chapter shall be permitted to remain on a site used for a cottage housing development and shall count as one of the allowed units. However, the extent of the noncompliance may not be increased unless the proposed change is determined by the Director to be consistent in character, scale and design with the cottage housing development. Repair, maintenance and reconstruction of an existing dwelling are regulated by Section 14.32.040. An existing dwelling may be replaced with cottage units consistent with this chapter.
(Ord. 798, Sec. 7 (Exh. 2), 2009)
The following density standards shall apply to cottage housing developments:
(a) 
Cottages may be built at up to two units per single-family home allowed in the underlying zone.
(b) 
Existing single-family dwellings will count towards total units.
(c) 
Minimum units per cluster: four.
(d) 
Maximum units per cluster: 12.
(e) 
Maximum units per cottage housing development: 24.
(f) 
Cottage housing developments are required to be a minimum of 500 feet from another cottage housing development.
(g) 
Carriage house units may be built on top of a common garage, when the garage is located adjacent to the common open area. No more than 25 percent of the total number of units may be located above a common garage.
(Ord. 798, Sec. 7 (Exh. 2), 2009)
(a) 
Common Open Area. The minimum common open area requirements set forth in this section are intended to provide a sense of openness, visual relief, and community in cottage housing developments. Common open areas shall provide a centrally located, focal area for the cottage housing development.
(1) 
At least 400 square feet of common open area per cottage is required for each cluster.
(2) 
Required common open area may be divided into no more than two separate areas per cluster.

To be considered as part of the minimum open space requirement, an area of common open area must have a minimum dimension of 35 feet on all sides.
(4) 
At least two sides of the common open area shall have cottages along the perimeter.
(5) 
Parking areas, yard setbacks, private open space, and driveways do not qualify as common open area. Community buildings can be counted towards the common open area calculations.

The intent of these access and parking standards is to minimize the visual impact of vehicles and parking areas for residents of the cottage housing development and adjacent properties and to provide for adequate off-street parking for cottage housing developments. It is the intent that shared detached garage structures be used for parking of vehicles used by the residents.
(a) 
Access. Access to a cottage housing development shall be consistent with Chapter 14.72 and Section 14.56.180.
(b) 
Minimum Number of Off-Street Parking Spaces.
(1) 
Minimum parking spaces requirement, including garage spaces and guest parking, shall be two per dwelling unit.
(2) 
Parking for a maximum of one vehicle per cottage shall be in a shared detached garage, provided the parking structure is adjacent to other parking spaces. Shared detached garage structures shall be reserved for the parking of vehicles owned by the residents of the development. Storage of items which preclude the use of the parking spaces for vehicles is prohibited.
(3) 
Guest parking may be clustered with resident parking and shall include clear signage identifying them as reserved for visitors.
(c) 
Parking Design. The intent of these parking design standards is to create unobtrusive parking, by screening and disguising parking structures and spaces from surrounding properties, including screening by architectural design and/or vegetation, and by minimizing the number of contiguous spaces.
(1) 
Parking areas or common garages shall be limited to no more than four contiguous spaces separated by a minimum of five feet of sidewalk, landscaping, or open space. The number of continuous parking garages or spaces shall be minimized.

(4) 
Parking shall be set back a minimum of 20 feet from a public street.
(5) 
The parking layout shall be designed to minimize walking distance to cottages.

(Ord. 798, Sec. 7 (Exh. 2), 2009)
(a) 
Cottage Size. The intent of setting a unit size is to ensure the overall size of cottages remains smaller and causes less visual impact than standard sized single-family dwellings, particularly given the increased density of cottage dwellings, and to provide variety in cottage housing developments through a mixture of building sizes and footprints.
(1) 
The total floor area of each cottage shall not exceed 1,500 square feet. No more than 25 percent of the total number of units shall be larger than 1,200 square feet.
(2) 
The footprint of each cottage shall not exceed 1,000 square feet. The total square foot area of a cottage dwelling unit may not be increased. A note shall be placed on the title to the property for the purpose of notifying future property owners that any increase in the total square footage of a cottage is prohibited for the life of the cottage or duration of City cottage housing development regulations.
(3) 
There shall be no minimum size requirements for the individual units, provided units meet the minimum livability standards as defined by Chapter 3 of the International Residential Code.
(4) 
The second floor area cannot exceed 75 percent of the first floor area.
(5) 
At least 25 percent of the cottages in each cluster shall have a gross floor area less than 1,000 square feet.

(i) 
Interior spaces with a ceiling height of six feet or less, such as in a second floor area under the slope of the roof;
(ii) 
Unheated storage space located under the main floor of the cottage;
(iii) 
Basements;

(g) 
Basements. Cottages may have basements.
(h) 
Fencing and Screening. The intent of internal decorative fencing and screening is to delineate private yards and screen parking structures, community assets and unit walls. A cottage housing development shall internally be an open community sharing common areas.
