Full Breakdown
20, General Standards and Limitations, governs freestanding accessory buildings countywide in the unincorporated area, and subsection E, Standards for Freestanding Accessory Buildings/Structures, sets the numeric rules a shed or detached garage must meet. a(6): five feet on lots under 10,000 square feet, ten feet on lots between 10,000 square feet and one acre, and 25 feet on lots of an acre or more. No accessory structure may sit in a required front, side, or rear setback except a permitted fence, wall, or ornamental pond, and outside T1, T2R, and T2RL zones and waterfront lots, a shed cannot project past the principal structure's front building line.
Structures other than fences, walls, pools, hot tubs, and AC compressors must sit at least five feet from the principal structure or any other accessory structure, and none may sit in a platted easement or over a known utility line. 2 caps all freestanding accessory structures on a lot at a combined 30 percent of the principal structure's floor area, except in the T2R district, where they must simply stay incidental and subordinate to the house. Standard two-car garages under 600 square feet, accessory dwelling units, agricultural structures, and home-business accessory buildings are excluded from that 30 percent cap. 4.
Violations & Fines
A shed placed inside a required setback, closer than five feet to the house, or exceeding the 30 percent combined floor-area cap is a Community Development Code violation subject to the county's zoning enforcement process, and a shipping container or tractor trailer used as a shed is barred outright regardless of setback or size.
