Florida Wind Zones at a Glance
The Florida Building Code 8th Edition (2023) divides the state into wind zones based on ASCE 7-22 design wind speeds (3-second gust, Risk Category II). The regulatory tier — High Velocity Hurricane Zone, Wind-Borne Debris Region, or Standard — determines what type of impact window certification a property needs.
| Zone | Counties | Wind Speed | Window Requirement |
|---|---|---|---|
| High Velocity Hurricane Zone (HVHZ) | Miami-Dade, Broward | 170–175 mph | Miami-Dade NOA required (TAS 201/202/203) |
| Wind-Borne Debris Region | Palm Beach, Monroe, Pinellas, Lee, Collier, Brevard, Hillsborough, Sarasota, Manatee, Pasco, Charlotte, Indian River, Martin, St. Lucie and other coastal counties | 130–170 mph | Florida Product Approval or Miami-Dade NOA |
| Standard | Interior North Florida counties | 105–130 mph | No impact certification required (recommended) |
What This Means for Your Windows
If your home is in the HVHZ, every window and door must carry a current Miami-Dade Notice of Acceptance (NOA). Products are tested by firing a 9 lb 2×4 at 34 mph, then cycling 9,000 pressure changes. The interlayer tear tolerance is just 5 inches × 1/16 inch — the tightest standard in the nation.
In the Wind-Borne Debris Region, impact-rated products or approved coverings are required on all new construction and major remodels. Florida Product Approval is the minimum; Miami-Dade NOA products are accepted everywhere in the state.
Even in Standard zones, impact windows are recommended for insurance savings, energy efficiency, noise reduction, and security.

Values are for general informational purposes only. Actual design pressures must be calculated by a licensed Professional Engineer using site-specific parameters (building height, exposure category, topography, opening location). Regulatory zones are based on Florida Building Code 8th Edition (2023) — verify with your local building department before purchasing products. Insurance ranges are estimates; actual savings depend on your insurer, coverage, and the results of a certified wind mitigation inspection (Form OIR-B1-1802).
How the Code Tiers Work
Florida is the only state in the nation that splits hurricane-prone areas into three regulatory tiers. Each tier prescribes the testing standard, certification, and exposure category that opening protections must meet.
- HVHZ — Miami-Dade County and Broward County. Products must carry a current Miami-Dade Notice of Acceptance, the strictest impact and pressure cycle test in the United States.
- Wind-Borne Debris Region — Areas where the design wind speed is at least 140 mph, or 130 mph within one mile of the coastal mean high-water line. Florida Product Approval is the minimum; Miami-Dade NOA products are accepted everywhere.
- Standard — Inland counties under 130 mph. No impact certification is required, though impact-rated products still qualify for insurance discounts and OIR-B1-1802 wind mitigation credits.
What the Numbers Represent
Design wind speeds are expressed as 3-second gust values from ASCE 7-22, the wind load standard adopted by the Florida Building Code 8th Edition. Risk Category II covers single- and multi-family homes (a 700-year mean recurrence interval); Risk Categories III and IV apply to schools, hospitals, and emergency facilities and use higher recurrence intervals.
The minimum DP rating for a window depends on building height, wall zone, and exposure category — the values shown are typical minimums for a single-story residential building in Exposure C. A licensed Professional Engineer must size design pressures for any permit.
