The HVHZ is Miami-Dade and Broward, and nowhere else

Florida's High Velocity Hurricane Zone — the strictest residential wind standard in the country — is defined by the Florida Building Code (Residential, R202) as Broward and Miami-Dade counties, and nowhere else. It does not extend north into Palm Beach and it does not include Monroe County or the Keys, both of which are common assumptions. Inside it, products need either statewide Florida Product Approval or a Miami-Dade Notice of Acceptance, and NOA testing includes large-missile impact and cyclic pressure testing. It is the strictest residential wind standard in the United States, and it is why a Miami home built to current code is a fundamentally different risk from one that is not.

Impact protection is the biggest lever, and it is all or nothing

Opening protection is the credit most often lost by accident, because it is scored on the WEAKEST opening in the house. One unrated window, one skylight, or a garage door nobody ever rated, and the whole category scores as unprotected — the other twelve openings earn you nothing. Interior blinds, decorative shutters and window film do not qualify.

The wind mitigation form itself changed in 2026

Florida law requires every residential property insurer to give actuarially reasonable discounts for verified windstorm mitigation features (Fla. Stat. 627.0629) — they are not a courtesy. The credits come from a wind mitigation inspection recorded on form OIR-B1-1802, and a revised version of that form became mandatory for inspections performed on or after April 1, 2026. An inspection done on the older form is still accepted if it was performed within five years before that date and nothing structural has changed since.

Miami home insurance questions

What does Miami-Dade NOA mean on my windows?

A Notice of Acceptance is Miami-Dade's local product approval, and its testing includes large-missile impact and cyclic pressure cycles. Inside the High Velocity Hurricane Zone a product needs either an NOA or statewide Florida Product Approval to be permitted.

Is the whole of South Florida in the HVHZ?

No. The Florida Building Code defines it as Broward and Miami-Dade counties only. Palm Beach is outside it, and so is Monroe County and the Keys, which surprises people given the exposure down there.

Will impact windows lower my Miami premium?

Rated opening protection is one of the largest wind mitigation credits available, and the discount is required by Florida law once verified. It is scored on the weakest opening in the house, so leaving one opening unrated commonly removes the credit entirely.

This page explains how Florida coverage and rating rules work in Miami-Dade County. It is general information, not advice about a specific policy, and it does not quote a rate — premiums depend on the property, the coverage selected and the carrier’s own underwriting. Statutory references are to the Florida Statutes and the Florida Building Code as they stand in 2026.
