Why Broward Is an HVHZ Jurisdiction
Broward County sits in the High-Velocity Hurricane Zone, a designation established under the Florida Building Code that mandates 175+ mph design wind speeds for all glazing assemblies. The HVHZ requirement is codified in FBC Chapter 16 and is enforced identically to Miami-Dade County's standards. In practice, that means every impact window installed in Broward — from a beachfront condo in Hollywood to a gated community home in Weston — must be tested to TAS 201 (impact resistance), TAS 202 (uniform static air pressure), and TAS 203 (cyclic wind-pressure loading). No product passes HVHZ review without documented compliance on all 3 protocols.
The HVHZ designation also determines which product approvals count. The Miami-Dade Notice of Acceptance database is the de-facto HVHZ standard, and Broward plan reviewers routinely accept Miami-Dade NOAs as proof of compliance. The NOA lists the exact test conditions — glass thickness, frame material, design pressure ratings — and any field configuration that deviates from those parameters triggers an immediate rejection. Contractors and homeowners should pull the current NOA before finalizing a window order, not after, because product lines change and an expired or superseded NOA is one of the top 4 rejection drivers reviewers cite.
