19.20.060 Accessory Uses, Buildings, or Structures.
A. All accessory uses, buildings, and structures must be customarily incidental and subordinate to the principal building or use of the lot upon which it is located.
B. Where there is a question regarding the inclusion or exclusion of a particular accessory use within any zone classification, the Zoning Administrator shall have the authority to make the final determination. The determination shall be based upon the general standards of this section and on an analysis of the compatibility of the use or structure with the predominant surrounding land use pattern and with the permitted principal uses of the zone classification.
C. The following structures are customarily incidental to residential uses:
1. Carports or garages for the sole use of occupants of premises and their guests, attached or detached, for storage of motor vehicles, boats, and/or recreational vehicles.
2. Greenhouses, private and non-commercial.
3. Storage buildings for yard maintenance equipment and household goods.
D. Accessory uses, buildings, and structures, other than fences and retaining walls, are prohibited from being located on a lot prior to a legal principal use.
E. Detached accessory buildings or structures are permitted in compliance with the use and bulk regulations and performance standards of this chapter, provided that:
1. The height of the accessory building or structure shall not exceed the maximum height listed in Table 2.
2. Detached accessory buildings or structures shall comply with the front and side yard setback requirements of this chapter.
3. There shall be no required rear yard setback except as required by the State Building Code. For the purposes of this section only, on a through lot, the Zoning Administrator may determine that one of the frontages of a through lot functions as a rear lot line and therefore does not require a rear yard setback for a detached accessory structure. In making such a determination, the Zoning Administrator shall consider the orientation of the primary structure on the lot and the development of other lots in the same area or neighborhood.
4. No detached accessory building or structure shall be constructed on or over right-of-way or on or over a public easement.
5. For structures accessory to residential uses in the R-1, R-2, and R-3 Zones, the total ground area of accessory structures may not exceed sixty percent (60%) of the total area of the primary dwelling unit, unless all of the following conditions are met:
a. The total area of all detached accessory structures does not exceed the size of the primary dwelling unit, or eight hundred and fifty (850) square feet, whichever is less.
b. No more than thirty-five percent (35%) of the lot may be covered by buildings.
c. The roof pitch of the accessory building(s) shall be at least three (3) vertical to twelve (12) horizontal, except for cargo containers which shall comply with Chapter 19.76.
6. The accessory building shall be at least five feet (5') from the primary building on the lot. Separation between accessory buildings shall be as regulated by the State Building Code. [Ord. 2023-08 § 5, December 2023.]
