Full Breakdown
A carport is an accessory structure in unincorporated Clay County and needs a building permit from the Building Division, including for prefabricated metal carport kits. It must meet the side and rear setbacks for its zoning district, stay within the 15-foot accessory-structure height limit, and be anchored to withstand the county's adopted 90-mph wind load. Attached carports are reviewed with the house, and freestanding ones as separate accessory structures. As a first-classification county, Clay County is statutorily empowered to require the permit and inspection. Deed restrictions in subdivisions may further limit or prohibit carports.
Violations & Fines
Erecting a carport without a permit brings a stop-work order and retroactive permitting, often at an increased fee. A carport inside a setback or under-anchored must be corrected or removed.
