Sec. 49.17. - Application and processing requirements.

Colusa County Zoning Code · 2026-06 edition · updated 2026-09-09 · Colusa County

(a)

Step One—Submittal. The application for a junior accessory dwelling unit permit shall be submitted to the department concurrent with an application for a building permit. In addition to the standard submittal requirements for a building permit, an application for a junior accessory dwelling unit permit shall include all the following:

a.

Plot plan. If any expansion of the foundation is required for a junior accessory dwelling unit, a plot plan, drawn to scale, showing the dimensions of the perimeter of the parcel proposed for the junior accessory dwelling unit; the location and dimensioned setbacks of all existing and proposed structures on the site and structures located within fifty feet of the site; all easements, building envelopes, and special requirements of the subdivision as shown on the final map and improvement plans, if any; and average slope calculations for the site.

b.

Floor plan. A floor plan, drawn to scale, showing the dimensions of each room, the area devoted to the junior accessory dwelling unit, and the resulting floor areas of the junior accessory dwelling unit and of the primary residence. The use of each room shall be identified, and the size and location of all windows and doors shall be clearly shown. The plan shall identify whether separate or shared sanitation facilities are proposed.

c.

Deed restrictions. Deed restrictions completed, signed and ready for recordation in compliance with subsection G.

(b)

Step Two—Decision. The department shall approve or deny an application for a junior accessory dwelling unit permit within sixty days of submittal of a complete application. A junior accessory dwelling unit permit shall be issued only if the proposed junior accessory dwelling unit complies with all applicable standards in this section. A permit for a junior accessory dwelling unit shall not be denied due to the correction of nonconforming zoning conditions, building code violations, or unpermitted structures that do not present a threat to public health and safety and are not affected by the construction of the junior accessory dwelling unit.
