18.51.010 Intent.

It is the intent of this chapter to:

A.    Provide opportunities for small, detached single-family housing types, clustered around an open space.

B.    Provide traditional cottage amenities and proportions to ensure that cottage housing developments contribute to the overall community character.

C.    Provide centrally located and functional common open space that fosters a sense of community.

D.    Provide semi-private areas around the individual dwellings to enable diversity in landscape design and foster a sense of ownership.

E.    Ensure minimal visual impact from vehicular use and storage areas for residents of the cottage housing development, as well as adjacent properties, and maintain a single-family character along public streets.

F.    Take advantage of existing natural features on the site including topography and vegetation, where desirable.

G.    Provide the opportunity for more affordable housing units.

H.    Promote conservation of natural resources by clustering smaller dwelling units.

I.    Provide energy-efficient dwelling units.

J.    Provide more opportunity for infill development.

K.    Provide incentives for green building certification and support low-impact development.

18.51.030 Development standards.

A.    Conflicts. Both the requirements of this chapter and those in the Citywide Design Guidelines are to be used for cottage developments. In instances where requirements conflict, the Citywide Design Guidelines requirements shall prevail.

1.    Planned Unit Development (PUD). If the cottage housing development is processed as a PUD, the standards for open space, parking, setbacks, and minimum distance between structures as specified in the Citywide Design Guidelines shall apply.

B.    Density. The density of the underlying zone governs unless a density increase is granted as provided in this chapter. The requirement for transfer of development rights (TDR) shall not apply to cottage developments.

1.    Density Increases. The city may allow up to two cottage units for each regular dwelling unit allowed in the underlying zone district.

C.    Cottage Clusters. Developments shall contain a minimum of four and a maximum of twelve dwellings located in a cluster to encourage a sense of community among the residents. A development site may contain more than one cottage cluster. The density bonus for clustering found in the underlying zone districts shall not apply to cottage developments.

D.    Floor Area. The maximum allowed gross floor area is one thousand two hundred fifty square feet per dwelling. Floor area does not include covered porches, detached garages, areas accessible only by ladders (e.g., lofts (IRC 311.4)), or accessory structures. Maximum footprint shall not exceed one thousand square feet.

1.    Cottages in the single-family low density zone district may not be smaller than five hundred square feet in size.

2.    One accessory structure (excluding detached garages, carports, or structures related directly to the use of the common open space area) is allowed per dwelling unit. This accessory structure may not exceed one hundred twenty square feet in size.

3.    One garage or carport (either detached or attached), not to exceed two hundred fifty square feet, is allowed per dwelling unit. Attached garages and carports must meet the requirements contained in the Citywide Design Guidelines.

E.    Platting. A cottage development may be completed through a land division and a planned unit development.

1.    Covenants, conditions and restrictions (CC&Rs) shall be submitted at the same time and in the same manner as required of any land division. In addition, CC&Rs for cottage developments shall address ownership and maintenance responsibilities, including but not limited to the following: the common open space areas, common drainage facilities, parking areas, and private roads. They shall also reflect the regulatory requirements regarding the minimum spacing requirements between structures (both primary and accessory) in effect at the time of final approval of the land division.

F.    Design. Cottages are subject to the design criteria in the Citywide Design Guidelines, this chapter, and TMC Chapter 18.43. Where there are conflicts between the Citywide Design Guidelines, TMC Chapter 18.43, and the standards in this chapter, the standards of the Citywide Design Guidelines shall prevail.

G.    Parking Requirements. The minimum required number of parking spaces is one per dwelling.

1.    Mixed use developments shall provide no less than one parking space per dwelling. The nonresidential portion of the development shall provide parking in accordance with the off-street parking requirements of TMC Chapter 18.50.

H.    Utility Elements. Utility meters and heating/cooling/ventilation equipment shall be located/designed to minimize visual impacts from the street and common areas.

I.    Existing Nonconforming Structure.

1.    On a lot to be used for a cottage housing development, an existing detached single-family residential structure, which may be nonconforming with respect to the standards of this chapter, shall be permitted to remain, provided the house and any accessory structures are not enlarged and the development meets the standards herein. The existing dwelling shall be included in determining the allowable density for the site.

J.    Accessory Dwelling Units.

1.    There shall be no more than one accessory dwelling unit for every five primary dwelling units.

2.    An accessory dwelling unit may be attached to or detached from a new or existing primary single-family dwelling unit.

3.    The accessory dwelling unit will require one parking space, which is in addition to any off-street spaces required for the primary single-family dwelling unit.

4.    The primary entrance to an accessory dwelling unit shall not be visible from the yard on the same side of the lot on which the primary entrance to the primary single-family dwelling unit is located.

5.    To ensure that the accessory dwelling unit is clearly secondary to the primary dwelling unit, the floor area for the accessory dwelling unit in no case shall exceed five hundred square feet, and the accessory dwelling unit shall contain no more than two bedrooms.

6.    The number and location of accessory dwelling units for a cottage housing development shall be limited to those shown on the original approved site plan for the development.
