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

Permit required

Yes. In Florida, addition or structural alteration generally requires a permit, and Unincorporated Lee 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 Lee 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. Lee County's own permitting office is the Lee County Community Development Department - Building & Permitting Services, reachable on (239) 533-8329 at https://www.leegov.com/dcd. Its online permit portal is https://aca-prod.accela.com/LEECO/Cap/CapHome.aspx?module=Permitting. 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. Lee County requires a Residential Addition to Primary Structure permit, pulled by a state-licensed contractor registered with Lee County or an owner-builder. In the Special Flood Hazard Area, if a non-compliant building's improvement cost equals or exceeds 50 percent of its value, the whole structure must meet current flood rules (FEMA BFE plus 1 foot). The county uses the Property Appraiser's structure value and its own FEMA valuation table, $165 per square foot for living area additions. Under LDC Sec. 6-116, a permit is valid 180 days from issuance or from the last approved inspection, and one 90-day extension can be requested in writing at least seven days before it expires. Enclosing part of a house built under truss before January 1, 1994 needs construction drawings, but not signed and sealed plans.
