The purpose of this chapter is to regulate and establish standards
for accessory structures within R-0, R-1, R-1.5, R-1.7/PD, R-2 residential
zoning districts, and DSP Blocks 8 through 12 and Block 17. Accessory
structures in other zon-ing districts are subject to development and
permitting requirements for those zoning districts.
(Ord. 2907-09 § 7)
(a) Measurement of Area. The area (square footage) of an accessory structure
is determined by measuring the floor area exclusive of eaves, overhangs
or other projections.
(b) Calculation of Height. The height of an accessory structure shall
be determined by measuring the vertical distance from the average
finished grade within five feet of the accessory structure, or within
five feet of the main building, whichever is less, to the highest
point of the accessory building.
(c) Appearance. All accessory structures greater than one hundred twenty
square feet shall be compatible in exterior appearance with the principal
structure on the premises. Permanent accessory structures are not
permitted to be constructed of temporary materials such as tarps,
plastic, or aluminum poles. The director of community development
is authorized to require modifications to the exterior of such an
accessory structure as necessary to achieve a compatible appearance.
(d) Total Lot Coverage and Required Rear Yard Coverage. Detached habitable spaces, detached required parking, and utility buildings are counted toward permitted lot coverage and rear yard coverage (as required in Sections
19.32.020 and
19.48.050). These structures shall not cause lot coverage or rear yard coverage to be exceeded unless otherwise approved by a use permit.
(e) Maximum Height. No accessory structure may exceed fifteen feet in
height unless otherwise approved with a use permit.
(f) Maximum Allowable Square Footage. Any single accessory structure or the total area of all accessory structures on a property shall not exceed four hundred fifty square feet unless otherwise approved by a use permit. In no event shall the total area of all accessory structures exceed eight hundred square feet. Legal accessory units as regulated in Chapter
19.68 shall be exempt from the maximum allowable square footage for accessory structures.
(Ord. 2907-09 § 7; Ord. 3105-16 § 7; Ord. 3154-20 § 5)
Accessory structures greater than four hundred fifty square
feet are subject to approval of a use permit. Permit requirements
for accessory structures four hundred fifty square feet or less are
described in Table 19.40.030.
