A new door on a hurricane coast. The rating is not optional
The garage door is the biggest opening in the house. If it fails in a storm, the roof is next. Florida requires approved doors, and the permit will be refused without one.
What is probably happening
- Florida requires state product approval for exterior doors, including garage doors, under Florida Administrative Code 61G20-3. The rule covers products that comprise the building envelope for compliance with the Florida Building Code.
- The door must carry a design pressure rating, in pounds per square foot, that meets or exceeds the design pressure for your opening. DASMA's wind load guide sets those pressures by wind speed, exposure and door size, and says doors shall include a manufacturer's label certifying the load.
- Miami-Dade and Broward are the High Velocity Hurricane Zone. Clopay's Florida guidance: both counties require all garage doors to meet the large missile impact rating, with or without windows. A Miami-Dade Notice of Acceptance (NOA) is the usual proof.
- Other Gulf and Atlantic coast states use the same design pressure approach through the International Residential Code, but the approval paperwork varies by state and county. Your building department is the final word. DASMA: the local authority having jurisdiction is the sole and final determiner of design wind pressure.
Do this in the next five minutes
- Call your building department and ask two things: the design wind speed and exposure for your address, and whether you are in the HVHZ or a wind-borne debris region.
- Ask every bidder for the Florida Product Approval number (FL number) or Miami-Dade NOA for the exact door model, and check it on floridabuilding.org or the Miami-Dade product control search yourself.
- Ask for the door's design pressure rating in writing and compare it to what the building department told you.
- Confirm who pulls the permit. It should be the installer.
- Keep the approval label on the door after installation. Insurers and buyers ask for it.
Do not
- Do not buy a door without a product approval number on a Florida coast. The permit will fail and the insurer can decline a storm claim.
- Do not accept 'hurricane rated' as a phrase. Ask for the design pressure number and the approval number.
- Do not let anyone skip the permit to save money.
Who to call
A garage door company that works in your county regularly
Wind-rated installation has extra bracing, fasteners and inspection steps. A company that does it weekly knows the local building department's paperwork.

Ask this contractor, on the phone, before anyone comes out
Tap each one as you ask it.
- What is the Florida Product Approval number or Miami-Dade NOA for this exact model and size, and what is its design pressure rating?
- Does that rating meet the design pressure the building department gave me for my address?
- Who pulls the permit and schedules the inspection, and is that in the price?
- Are the reinforcement struts, jamb brackets and fasteners in the approval document the ones you are installing?
End the call if
- No approval number offered, or 'it is hurricane rated' with no paperwork.
- An offer to install without a permit.
- Full payment or a large cash deposit before the door is ordered.
