ACCESSORY STRUCTURES
Sections:
17.46.020 Permit Requirements And Exceptions
17.46.030 Development Standards
17.46.010 Purpose:
The purpose of this chapter is to identify and regulate detached accessory structures to ensure that such structures do not create public safety or nuisance issues, do not create an adverse aesthetic from street right of ways, and do not create a negative impact (light, air, drainage, or aesthetic) on surrounding properties. (Ord. 473 §3, 2007)
17.46.020 Permit Requirements And Exceptions:
Accessory structures governed by this chapter shall go through a simple plan check (zoning clearance) at the time a building permit is issued to ensure compliance with applicable regulations. However, in accordance with division II, "Administration And Permit Procedures", of this title, some larger, enclosed accessory structures may require a design review approval to ensure compliance with all applicable provisions of this title. Accessory structures may be subject to building permit requirements. The following structures shall be exempt from the requirements of this chapter as specified below and are subject to compliance with all other provisions of this title:
A. Accessory Structures: Enclosed and/or solid roofed accessory structures that are one hundred twenty (120) square feet or smaller in size with no portion of the structure equal to or greater than eight feet (B’) in height. Structures shall not be located in a required front yard. In order to maintain necessary fire breaks, all combustible accessory structures shall be set back a minimum of three feet (3') from side and rear property lines with a minimum six foot (6') separation between structures.
B. Landscape Features: Landscape features that are one hundred twenty (120) square feet or smaller in size with no portion of the structure equal to or greater than eight feet (B’) in height. In order to maintain necessary fire breaks, combustible landscape features shall be set back a minimum of three feet (3') from all interior property lines with a minimum six foot (6') separation between structures.
C. Play Equipment: Structures and surfaces used for recreational purposes including play structures, jungle gyms, and sports courts such as tennis and basketball courts, excluding associated fencing.
D. Deck/Patio: A porch or platform that is generally constructed with wood, concrete, or stone that is above the natural grade or located over a basement or story below.
E. Pool/Spa: Any structure intended for swimming or recreational bathing that contains water over eighteen inches (18") deep. Swimming pool includes inground and aboveground structures and includes, but is not limited to, hot tubs, spas, portable spas and nonportable wading pools. (Ord. 473 §3, 2007)
17.46.030 Development Standards:
A. Supplemental Structures: The development standards in this section are intended to supplement the standards in the underlying zoning district for accessory structures. If similar accessory structures are attached to the main building, the governing regulations shall be as listed in this chapter. In the event of conflict between these standards and the underlying zoning district regulations, the provisions of this section shall apply.
1. Setback Measurement: Minimum setback distances for accessory structures from property lines and between accessory structures includes all portions of the structure(s) (e.g., overhangs, projections, railings) for the purpose of compliance with minimum structural fire breaks.
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 the residential estate zoning district where accessory structures may be constructed prior to the primary residential dwelling.
B. Development Standards By Type Of Accessory Structure: Table 17.46-1 of this section establishes development standards based on the type of accessory structure as defined in section 17.46.020, "Permit Requirements And Exceptions", of this chapter. In no event shall the accessory structure(s) collectively exceed a maximum thirty percent (30%) coverage of the actual rear yard area. In the residential estate zoning district, the maximum rear yard coverage is twenty five percent (25%).
