Shed permit rules in Dunnellon, FL — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
In unincorporated Marion County, FL, prefab sheds 160 sq ft or smaller (e.g., 10×16) generally do not require a building permit, provided setback and zoning requirements are met. Anything over 160 sq ft requires a building permit. Accessory structure setbacks are 25 ft front, 8 ft side, 8 ft rear with a 20 ft max height.
Marion County adopted the Florida Building Code (then-current 2017 edition) via Ordinance 20-21, with an automatic-update provision that pulls in subsequent FBC supplements 60 days after their adoption. Land Development Code Sec. 4.3.27 governs accessory structures: they must be located in the rear or side yard, and on lots one acre or smaller the rear and side yard setbacks are a minimum of 8 feet. Detached sheds and carports not exceeding 12×12 may be exempted from side or rear setbacks if both adjacent property owners sign a notarized agreement filed with Growth Services before placement. Marion County Building Safety: 352-438-2400.
Building a shed over 160 sq ft without a permit, or violating setback rules, can trigger code-enforcement fines, stop-work orders, and orders to remove the structure. Penalties continue until the violation is cured or a permit is issued and inspections passed.
