Many people ask: are impact windows required in Florida? The answer depends on where you live and what work you are doing.
The basic rule
The Florida Building Code requires windborne debris protection for exterior openings in many parts of the state, including most of coastal South Florida. "Protection" can mean impact-rated windows and doors, or approved storm shutters. So the code does not say "you must have impact windows", it says openings must be protected, and impact glass is one way.
When it applies
- New construction and additions: openings must be protected.
- Window and door replacement: new products generally must meet current code, which in many areas means impact-rated product or approved protection.
- Existing, unchanged windows: usually not forced to upgrade, but you may face insurance or resale pressure.
Miami-Dade and Broward are stricter
These counties are the High-Velocity Hurricane Zone. Products need a Miami-Dade NOA, and permits and inspections are required. See impact window requirements in Broward and Miami-Dade.
Your options
Choose between impact windows and shutters. Either way, hire a licensed contractor who pulls the permit. Not sure what your openings need? Our team can review them. Ask your local building department for the final word on your address.
What "windborne debris region" means
The building code defines windborne debris regions based on design wind speeds and proximity to the coast. In these areas, glazed openings must be protected from flying debris, because broken glass during a hurricane leads to pressurization of the house. Most of coastal South Florida falls in these regions, and Miami-Dade and Broward are stricter still as the High-Velocity Hurricane Zone.
What counts as acceptable protection
- Impact-resistant glazing (impact windows and doors) with a valid product approval.
- Approved storm shutters, such as accordion, roll-down or panel systems.
- In some limited cases, approved plywood panels for certain older structures, depending on local rules.
Replacing windows triggers current code
If you remove windows and install new ones, the new installation generally has to meet current code, which in protected regions means impact-rated product or approved protection plus a permit. This is why many owners who start with "I just want new windows" end up with impact glass.
Insurance and lenders also care
Even where the code does not force an upgrade, insurers may price your policy based on your opening protection, and some lenders ask about it on older homes. A wind mitigation inspection documents what you have.
How to confirm for your address
- Call your city or county building department and ask what applies to your property.
- Ask your contractor which products are approved for your location.
- Check HOA or condo rules for appearance and approvals.
Rules change, so always confirm current requirements locally. See also requirements in Broward and Miami-Dade.
