Broward County sits in Florida's High-Velocity Hurricane Zone. Every window must meet strict design pressure and impact resistance standards. Here's what you need to know.
Key requirements for hurricane window installations in Broward County.
9-lb 2x4 lumber at 34 mph for large missile test. All glazing within 30 feet of grade must pass.
Varies by exposure category, building height, and window location. Corners require higher ratings.
All impact windows must have valid Notice of Acceptance from Miami-Dade Product Control.
Anchoring, flashing, and sealant must follow manufacturer's tested installation methods.
Ultimate design wind speed for Broward County per ASCE 7-22. 3-second gust at 33 feet.
Building permit required for all window replacements. Inspections verify NOA compliance.
Design pressures vary based on building characteristics and window placement.
| Building Type | Exposure | Field of Roof | Wall Zone 4 | Wall Zone 5 |
|---|---|---|---|---|
| Single-Family (1 Story) | C | +/-45 PSF | +/-55 PSF | +/-65 PSF |
| Single-Family (2 Story) | C | +/-50 PSF | +/-60 PSF | +/-70 PSF |
| Townhome/Condo (3 Story) | C | +/-55 PSF | +/-65 PSF | +/-75 PSF |
| Mid-Rise (4-6 Story) | C | +/-60 PSF | +/-70 PSF | +/-85 PSF |
| High-Rise (7+ Story) | D | +/-70 PSF | +/-85 PSF | +/-100 PSF |
Understanding your options for Broward County compliance.
Non-impact glass with protection
Laminated hurricane glass
Broward County requires minimum design pressures based on building location and height. Most residential windows need +/-45 to +/-65 PSF, while high-rise and coastal properties may require +/-75 PSF or higher. Corner zones always require higher ratings than field areas.
Yes, Broward County is within the High-Velocity Hurricane Zone (HVHZ). All exterior glazing must be impact-rated OR protected by approved hurricane shutters. If using impact windows, they must have a valid Notice of Acceptance (NOA).
A Notice of Acceptance (NOA) is a product approval document issued by Miami-Dade County that certifies a window meets HVHZ requirements including impact resistance and design pressure. Broward County accepts Miami-Dade NOAs for hurricane window installations.
No. Broward County requires licensed contractors for hurricane window installation. The permit process includes inspections to verify proper anchoring, flashing, and compliance with the NOA installation specifications. DIY installation will not pass inspection.
