Full Breakdown
1 of the Unified Development Ordinance carves accessory structures out of the county's standard 20-foot rear setback: a shed, detached garage, or similar building may be located no closer than 3 feet to the rear property line, or to an easement line where an easement crosses the lot. The Subdivision Regulations repeat the identical 3-foot allowance in their own Building Setback Lines section for lots platted after July 3, 1972, so the rule holds whether the parcel came from a subdivision plat or was developed individually.
6 layers on additional conditions: the structure cannot be used for human habitation, cannot be temperature-controlled, must be designed for low flood-damage potential, must be sited to offer minimum resistance to floodwater flow, must be firmly anchored, and must include flood openings below the Regulatory Flood Protection Elevation to equalize hydrostatic pressure. The ordinance then grants a size-based exemption from the elevation and floodproofing standards themselves: an accessory structure with a footprint under 150 square feet, or representing an investment of $3,000 or less, is not required to meet those requirements as long as it satisfies the anchoring and design criteria above.
Any larger or more valuable accessory building in a flood hazard area must be elevated or floodproofed and certified like a primary structure, and its placement still must respect the 3-foot rear setback that applies countywide.
Violations & Fines
An accessory structure built closer than 3 feet to the rear or easement line, or a shed in a flood hazard area that skips the required anchoring and elevation openings, violates the Unified Development Ordinance. The Planning Director allows 30 days under Section 4.3 to correct the problem before further enforcement. Uncorrected violations carry a $500 civil citation per Section 4.4, assessed per day the violation continues.
