A. Development Standards for All Accessory Structures. The development standards listed in Table 17.30.040-1 (Development Standards for Accessory Structures) are intended to supplement the requirements in the applicable zoning district for types of accessory structures as defined in Article VI (Glossary) of this title. Figure 17.30.040-1 shows minimum setback measurements for a typical detached accessory structure. In the event of a conflict between these requirements and the underlying zoning district regulations, the requirements of this Section shall apply. The following requirements shall apply to all accessory structures, both exempt and nonexempt under Section 17.20.030.
1. Setback measurement. Minimum setback distances for accessory structures from property lines and between all structures shall include all portions of the structure(s) (e.g., overhangs, projections, railings) for the purpose of compliance with minimum structural fire breaks. See Figure 17.30.040-1 (Setback Measurements for Accessory Structures).
2. Construction phasing. Accessory structures may be constructed in conjunction with or subsequent to (but not in advance of) construction of the primary building(s) on the site. Exceptions may be granted in agricultural and residential zoning districts where accessory structures may be constructed prior to the primary residential dwelling.
Accessory Structure (Type) | Minimum Setback Distance from Property Line or Other Structures | Maximum Cumulative Lot Coverage | Maximum Height | Maximum Number or Yard Area Ratio | ||||
Front | Rear | Side | Other Accessory Structures | Primary Building

Enclosed Solid Roof Building | Not permitted | 5 ft.(1) | 5 ft.(1), (2) | 6 ft. | 0 ft. (1),(3) | 50% required yard area | 15 ft. | 1 or 1 per 1200 sq. ft. yard area, whichever is greater |

(1) Accessory buildings not exceeding fifteen (15) feet in height at the highest point may be built within five (5) feet to the side and/or rear property line, provided that the accessory structure is not less than six (6) feet in distance from the primary building on the parcel.
(2) For reverse corner lots, the street side yard setback shall be the same as the front yard setback for the adjacent key lot. See Figure 17.42.030-1
(3) No minimum setback required for attached accessory buildings. Accessory buildings may be attached to and have a common wall with the main building or, when located as required by this chapter, may be connected to the main building by a breezeway.
(4) Measurement from water's edge. Related equipment shall be set back a minimum of three (3) feet from all side and rear property lines. (Ord. 2010-02 § 1 (part), 2010)
