Do I need a permit for addition or structural alteration in Unincorporated Marion County?

Permit required

Yes. In Florida, addition or structural alteration generally requires a permit, and Unincorporated Marion County is no exception.

A building permit is required for any addition and for structural alterations such as removing or altering load-bearing walls, changing the footprint, or altering the roof structure. The Florida Building Code only exempts ordinary minor repairs that do not cut into walls or remove load-bearing supports, so structural work is never exempt. Additions usually trigger zoning review and, in flood areas, elevation requirements.

Florida and local notes for Unincorporated Marion County

Structural work is specifically excluded from the HB 803 $7,500 exemption. Signed and sealed engineered plans are commonly required. Additions often trigger setback, lot-coverage, and floodplain review. Marion County's own permitting office is the Marion County Building Safety office, reachable on (352) 438-2400 at https://www.marionfl.org/agencies-departments/departments-facilities-offices/building-safety. Its online permit portal is https://permits.marionfl.org. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Florida municipalities do not, this is the office that will handle the job. An addition means a full plan review, so confirm submittal requirements and current review times before you commission drawings. Unincorporated Marion County addresses are permitted by Marion County Building Safety (2710 E. Silver Springs Blvd., Ocala, 352-438-2400), and all permit documents are submitted electronically through the Civic Access portal. Marion County lists residential additions and alterations among the permits that require plan review, and approval by other county departments, including Zoning (352-438-2675), must be obtained before the permit is issued. Every new structure or addition needs an individual stormwater drainage plan at application, and residential sites are inspected for compliance with it alongside the structural inspections (Code Secs. 5.5-33 and 5.5-36). Marion County Code Sec. 5.5-36 adds a slab inspection and an insulation inspection to those listed in the Florida Building Code.
