Florida Building Code — Key Post-Hurricane Provisions
Florida has some of the nation's strictest building codes for hurricane exposure. This guide covers the key FBC provisions that affect HOA and COA hurricane repair decisions — and why they matter for your estimates.
Important
The Florida Building Code is updated every 3 years (every 6 years with the current cycle). Post-Hurricane Ian amendments significantly tightened requirements for roof replacement, impact-resistant openings, and structural connections. Your permits must comply with the code edition in effect at the time of permit application.
Florida Building Code Editions Relevant to Hurricane Repair
| Edition | Effective | Key Changes |
|---|---|---|
| 7th Edition (2020) | Dec 31, 2020 | Current base code. Includes updated wind load maps. |
| 8th Edition (2023) | Dec 31, 2023 | Post-Ian amendments. Major changes to roof, opening, and structural provisions. |
| 9th Edition (2026) | Expected Dec 2026 | In development. May include additional climate resilience provisions. |
The Florida Building Code is administered by the Florida Building Commission. Access the full code at floridabuilding.org.
Key Provisions for Hurricane Repair
Chapter 15 — Roof Assemblies
Post-Ian: Roof replacements must meet updated uplift ratings. The entire roof assembly (not just shingles) must be re-permitted. Recover vs. replacement rules have changed.
Section 1405 — Metal Wall Systems
Siding, stucco, and exterior finishes must be evaluated for wind-driven rain intrusion. Water intrusion damage behind walls must be addressed to code, not just cosmetic repair.
Section 107 — Permits
Most hurricane repairs over $5,000 require a building permit. This is non-negotiable. A contractor who says 'we don't need a permit' is a red flag.
Section 1609 — Wind Loads
Florida has region-specific wind speed maps. Coastal communities face higher design wind loads (150–200 mph in some zones). Verify your property's zone.
Section 110.7 — Window and Door Protection
Post-Ian: Impact-resistant openings are required in High Velocity Hurricane Zone (HVHZ) counties — Miami-Dade and Broward. Other counties may also require them depending on location.
Chapter 4 — Existing Buildings
Alterations and repairs must meet current code, not the code at the time of original construction — unless specifically exempted. This is a common source of estimate disputes.
Why FBC Compliance Matters for Estimates
If your contractor's estimate assumes pre-Ian building standards, the actual cost will exceed the estimate because the scope is incomplete. Code-compliant repairs typically cost more because:
- →Full roof replacement (vs. overlay) costs more but is now required in many cases
- →Impact-resistant windows are more expensive but mandatory in HVHZ
- →Enhanced structural connections add material and labor
- →Permit fees are higher for code-compliant work
- →Engineering inspections (4th inspection) may be required
Verify Permits Before Signing
Before signing any contract, ask the contractor: "What permits are required, and have you pulled them?" A legitimate contractor will pull the permit in their name (not yours). Check with your county building department to confirm.
Note: The HOA or COA (as the property owner) is ultimately responsible for ensuring permits are pulled — not the contractor. If the contractor doesn't pull permits, the board should require it in writing in the contract.
