21 COTTAGE HOUSING
Cottage | |
|---|---|
Minimum Site Size1 | 0.5 acres |
Maximum Unit Size2 | 1,500 square feet3 |
Not to exceed 1,000 square feet on the main floor. Second floor square footage shall not exceed 75% of ground floor square footage | |
Density | Two (2) times the maximum number of detached dwelling units allowed in the underlying zone 4, 5, 6, 7 |
Minimum Lot Size | Beyond density restrictions, there is no required minimum lot size for lots created through the subdivision process. (The number of allowed units on the subject property is determined by the density provision of this chart.) |
Floor Area Ratio (FAR)8 | 0.35 |
Development Size | Minimum: 4 units |
Maximum: 18 units | |
Maximum cluster9: 12 units | |
Location | Developments containing cottage and/or two- and three-unit homes may not be located closer than the distance noted below to another development approved under the provisions of this chapter: |
1 to 9 Units: 500 feet | |
10 to 18 Units: 1,000 feet | |
Parking Requirements10 | Units 900 square feet or less: 1.5 spaces per unit |
Units over 900 square feet: 2 spaces per unit | |
Must be provided on the subject site | |
Minimum Required Yards (from exterior property lines of subject property)11 | Front: 20 feet |
Public Street: 15 feet | |
Interior and Rear: 10 feet | |
Lot Coverage (all impervious surfaces)12 | 50% |
Height | |
- Dwelling Units | 25 feet (where minimum roof slope of 6:12 for all parts of the roof above 18 feet is provided). Otherwise, 18 feet |
- Accessory Structures | One story, not to exceed 18 feet |
Tree Retention and Street Trees | Standards contained in Chapter 11.28 PMC and vegetation management standards shall apply to development approved under this chapter |
Open Space | 400 square feet of common open space required per unit. See PMC § 20.21.030(3) for further regulations |
300 square feet of private open space required per unit. See PMC § 20.21.030(4) for further regulations | |
Community Buildings | Community buildings are required. See PMC § 20.21.030(2) for further regulations |
Attached Covered Porches | Each unit must have a covered porch with a minimum area of 64 square feet per unit and a minimum dimension of 7 feet on all sides |
Development Options | Subdivision |
Condominium | |
Rental or ownership | |
Accessory Dwelling Units (ADUs) | Not permitted as part of a cottage development |
Notes: | |
|---|---|
1 Site shall include any parcel or combination of contiguous parcels which make up the entire project development site. | |
2 A covenant restricting any increases in unit size after initial construction shall be recorded against the property. Vaulted space may not be converted to habitable space. | |
3 Maximum size for a cottage is 1,500 square feet. Cottage areas that do not count toward the maximum size calculation are: | |
a. Unheated storage space located under the main floor of the cottage. | |
b. Architectural projections, such as bay windows, fireplaces or utility closets not greater than 18 inches in depth and six feet in width. | |
c. Attached roofed porches. | |
d. Garages. | |
e. Interior spaces with a ceiling height of six feet or less, as in a second floor area under the slope of the roof. | |
4 Existing detached dwelling units may remain on the subject property and will be counted as units. Any nonconforming aspects with respect to the standards of this chapter shall be permitted to remain; however, the extent of the nonconformities shall not be increased unless the proposed change is determined by the planning director to be consistent in character, scale and design with the cottage development. | |
5 When the conversion from detached dwelling units to equivalent units results in a fraction, the equivalent units shall be limited to the whole number less the fraction. | |
6 See PMC § 20.20.040(16) and § 20.25.040(18) for density calculation on a site that contains critical area buffers. | |
7 To determine equivalent units for a two- or three-unit home, the following formula will be used: Lot area/min. lot size per unit in underlying zone x 2 = maximum units (always round down to nearest whole number). Example: (RS-08 zone): 24,000/8,000 = 3 x 2 = 6 units. | |
8 FAR regulations: | |
b. All structures on site shall be included in the FAR calculation for the development. FAR for individual lots may vary. | |
9 Cluster size is intended to encourage a sense of community among residents. A development site may contain more than one cluster, with a clear separation between clusters. | |
10 If the subject site is within one-quarter mile of a transit station or park and ride facility and on-street parking is available on streets adjacent to the subject site, parking ratios may be reduced by 0.5 stalls per dwelling unit. | |
11 Setbacks shall be measured to any structure from all exterior property lines of the subject site. | |
12 Lot coverage is calculated using the entire development site, excluding critical areas and their buffers. Lot coverage for individual lots may vary. | |
