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

Permit required

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

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. Collier County's own permitting office is the Collier County Building Plan Review and Inspection Division, reachable on 239-252-2400 at https://www.collier.gov/Business-Resources/Building-Permits-Construction. Its online permit portal is https://cvportal.collier.gov/cityviewweb. 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. Naples' addition checklist says no inspections can be scheduled after the slab is placed until the Building Department approves an Elevation Certificate and the Planning Department approves a spot survey. The spot survey is due within 10 days of the pour, or a stop work order issues. The city notes that the Florida Building Code requires a one- and two-family lowest floor at Base Flood Elevation plus 1 foot in all flood hazard areas, and additions always require a Final Elevation Certificate. Additions require a Notification and Offer Form with letters mailed to adjacent owners, and projects in the Coastal Building Zone need plans digitally signed and sealed by a design professional. Generators, fences, pools, screen enclosures, and shutters tied to the project must each be permitted separately.
