A. Description. Cottage housing is a grouping of small compact, detached single-family dwelling units clustered around a common area and developed with a shared plan for access and parking, and a coordinated design for the buildings and site.
B. Site Requirements and Setbacks.
1. Cottages may be located on a separate (fee simple) lot or several units may be located on a common parcel.
2. The required setbacks are as shown in Figure 20.28.080(A), except garage and carport setbacks from an alley shall be as needed to provide a 20-foot parking backup distance (including alley width). Buildings shall be placed within the shaded areas shown in the figure.
C. Bulk and Massing.
1. The minimum is four dwelling units and the maximum is eight dwelling units in a single development.
2. No structure shall be larger than 1,000 square feet and no single floor area shall be larger than 600 square feet.
3. Maximum floor area ratio (FAR) is 0.4.
4. Common shared structures are allowed, limited to the same bulk and mass restrictions as dwelling units, and are exempt from FAR.
5. The height limit is 25 feet under BMC 20.08.020, definition No. 1 or 15 feet under definition No. 2.
D. Open Space.
1. Each dwelling unit shall have at least 100 square feet of private usable open space with no dimension less than five feet. Decks may be included.
2. Private usable open space must be directly accessible from the dwelling unit, and be separated from shared spaces or paths and other units.
3. Common usable open space equivalent to 500 square feet per dwelling unit shall be provided. No single dimension shall be less than 20 feet, exclusive of parking or lanes except for emergency access. All units shall have direct access to shared open space.
4. A minimum of 60 percent of the site area shall be in landscaping or permeable materials (may include permeable paving, landscape-based LID BMPs, and green roofs). Exceptions may be made in erosion hazard zones or areas with shallow bedrock as determined by the city.
1. The project shall include at least one on-site parking stall per unit. The planning director may reduce parking requirements based on applicant’s demonstration of site-specific factors that justify a lower standard. Parking stalls shall be at least nine feet by 18 feet, unless adjacent to landscaping, as specified in Figure 20.12.030(A).
2. Parking may not be located between structures or front directly upon a street.
3. If an alley exists, parking shall be accessed via the alley except when the planning director determines that alley access is impractical or environmentally constrained.
4. Parking shall be consolidated in areas not less than four spaces.
5. Parking accessed from the public street shall be limited to one driveway of 20-foot maximum width.
6. Parking shall be screened from the public street by landscape feature or fence.
F. Design Standards.
1. A front porch with a minimum of 60 square feet and no dimension less than five feet is required for each dwelling unit (in addition to private open space requirements).
2. Dwelling units that front a public street or lane shall have a porch that faces the street or lane. Units that face the shared open space shall have a porch that faces the open space. In some cases, units will require two front porches to satisfy this criteria.
3. All fences in the front and side street setbacks, or between the common areas and the dwelling units, are limited to 42 inches in height and may be no more than 60 percent opaque. Chain link or cyclone fencing is not allowed in the front or side street yard.
G. Design Guidelines. Cottage housing developments should architecturally blend into existing neighborhoods through careful attention to the design of the units, open spaces, parking and landscaping. Well proportioned cottage houses, with porches, small gardens, varied roof lines and dormers can fit comfortably into surrounding neighborhoods of older, detached homes.
a. Buildings should employ variety in orientation, design, and layout between cottages while maintaining a similar character to help distinguish units and support a neighborhood feel.
b. Cottages should reflect common neighborhood design features such as porches, dormers, gables, and architectural detailing.
c. Changes in materials, colors or textures and colors to add visual interest and character to the development are encouraged.
2. Site Design.
a. Provide small private open spaces in conjunction with a large shared open space.
b. Provide generous use of landscape structures such as trellises, gate houses, decks, patios, and raised beds to provide plenty of usable outdoor space with a variety of environments. Use planting materials and elements such as fencing to unify the overall site design.
c. Shared driveways are preferred.
