Do I need a permit for addition or structural alteration in Fernandina Beach?

Permit required

Yes. In Florida, addition or structural alteration generally requires a permit, and Fernandina Beach 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.

Local detail for Fernandina Beach: City of Fernandina Beach Building Department (Community Development) issues its own permits; online permitting available.

Florida and local notes for Fernandina Beach

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. Nassau County's own permitting office is the Nassau County Building Department, reachable on (904) 530-6250 at https://www.nassaucountyfl.com/136/Building-Department. Its online permit portal is https://nassaucitizens.munisselfservice.com/citizens/default.aspx. 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. Under Code section 22-250, no building permit for an addition or alteration is issued until a construction site management plan is submitted and approved by the Building Official. Fernandina Beach uses a 30 percent threshold for substantial improvement in a Special Flood Hazard Area. If the work costs 30 percent or more of the structure's value (by default the Nassau County Property Appraiser's assessed value), the whole building must be brought into compliance, including elevation. For flood review, the city requires a detailed cost estimate signed by a licensed contractor, an affidavit that it covers all improvements, and a signed contract with the permit application. In a historic district or the CRA, additions need a Certificate of Approval under LDC 8.03.03. The matrix separates additions not visible from the street and 20 percent or less of the existing square footage from all other additions.
