Flood panel and flood barrier permits in Southwest Florida (2026)
Florida's HB 803, effective July 1, 2026, exempts some temporary flood barriers on single-family homes, duplexes and townhouses from building permits, but the exemption does not apply to property in a flood hazard area. Most coastal Southwest Florida homes are in one, so attached flood panels there still need a permit, usually with an engineer's evaluation.
The 2026 exemption (HB 803)
HB 803 (Chapter 2026-63) created a permit exemption for temporary, non-habitable, non-load-bearing flood or storm-surge barriers on single-family homes, duplexes and townhouses. To qualify, the barrier must be installed by a contractor licensed under Part I of Chapter 489, meet zoning, drainage, easement and setback rules, and the owner or contractor must send a written request with the contract to the building department. It does not apply to property "partially or entirely located in a flood hazard area" (Florida Senate; City of Naples explainer).
What a permit package includes
Florida's Division of Emergency Management lets communities permit the brackets and anchors attached barriers need. Applications typically include (FDEM guidance, January 2026):
- a signed engineering evaluation of the walls the barrier attaches to
- floor plans showing every opening
- product details and installation, deployment and maintenance instructions
- an estimate of how long deployment takes
- a notarized owner acknowledgment of the risks
Local requirements
| Place | What applies |
|---|---|
| Collier County and City of Naples | Permits for panels on existing homes; engineer's review, shop drawings and elevation certificate are typical (Gulfshore Business) |
| Fort Myers Beach | Attached panels are structural alterations; no residential dry floodproofing in V and Coastal A zones; keep one emergency exit clear (Town of Fort Myers Beach). In June 2026 the town said residential panels are "not permittable" (Pine Island Eagle) |
| Unincorporated Lee County | 50% substantial improvement rule in A and V zones (Lee County). County officials said in June 2026 that unincorporated residential applicants are not eligible for panel permits (Pine Island Eagle) |
| Cape Coral | 50% substantial improvement rule (City of Cape Coral) |
Flood vents cut openings into exterior walls; treat them as permit-required and confirm with your building department.
Where barriers are not allowed
Barriers "MUST NOT be approved" on buildings in V zones built after the community joined the NFIP, on residential buildings in Coastal A zones built after December 31, 2017, or when the barrier work plus other work adds up to a substantial improvement (FDEM guidance).
