Full Breakdown
Sec. 9 of the UDO governs accessory structures countywide, and the rules scale with lot size. Sec. 3 sets a flat setback for every accessory structure regardless of acreage: at least 5 feet from the principal structure and 10 feet from any rear or side yard line. For the smallest tier, lots under two acres, Sec. 1 adds a height ceiling of 20 feet, bars any accessory structure from the front yard, caps the combined square footage of all accessory structures on the parcel at 4% of the lot's acreage, limits each individual structure's footprint to no more than the primary house's under-roof footprint per current tax records, and allows no more than two accessory structures plus a garage or carport on the lot.
Larger lots get more room: two-to-four acre parcels can go to 45 feet in height and 5% lot coverage with three structures, and lots four acres and up reach 6% coverage with four structures. Sheds also fall under Sec. 7).
Violations & Fines
An oversized, misplaced, or unpermitted shed draws a notice of violation from the Zoning Administrator with a deadline to correct it, whether that means relocating the structure, reducing its footprint, or obtaining the missing permit. If the deadline passes without correction, the county can impose a civil penalty of $100 per day under UDO Chapter 18 until the shed is brought into compliance.
