The city council shall find an application for not more than one accessory dwelling per existing primary single-family dwelling is consistent with this chapter if the applicant shows compliance with the following criteria and standards:
A. A maximum of one accessory dwelling is allowed per legal single-family dwelling. The unit may be a detached building, in a portion of a detached accessory building (e.g., above a garage or workshop), or a unit attached or interior to the primary dwelling (e.g., an addition or the conversion of an existing floor).
B. The exterior of the proposed accessory dwelling unit shall match the main residence in terms of finish materials, roof pitch, trim, and window proportion and orientation.
1. Exterior Finish Materials. Exterior finish materials must visually match, in type, size and placement, the exterior finish materials of the primary dwelling.
2. Windows. If the street-facing façade of the ADU is visible from the street, its windows must match, in proportion and orientation, the windows of the primary dwelling.
3. Eaves. If the primary dwelling has eaves, an attached ADU must have eaves that project the same distance from the building. If the primary dwelling does not have eaves, no eaves are required for the ADU.
4. Adjustments to these standards can be sought through an application for a variance.
C. The application is consistent with applicable building and fire safety codes. [Ord. 9-D § 1.]
