What is a Miami-Dade NOA?

A Miami-Dade NOA is a Notice of Acceptance issued by Miami-Dade County's product control division. It certifies that a specific building product, such as a window, door, skylight, or shutter, has passed the county's testing for the High-Velocity Hurricane Zone (HVHZ), the area covering Miami-Dade and Broward counties where the building code is stricter than the rest of Florida.

The NOA is more than a test report. It lists the exact product, its approved sizes and configurations, the glazing and framing details, and the design pressures the product can handle. Testing typically involves large-missile impact, where a projectile is fired at the product to simulate wind-borne debris, followed by cyclic pressure cycling that mimics the push and pull of hurricane winds. A product only receives an NOA if it survives both stages.

Because the HVHZ rules apply in South Florida, a Miami-Dade NOA is the document local permit offices look for when a product is installed in that zone. For skylights, the NOA defines what can legally go in a given roof opening and under what conditions. Products carrying an NOA are generally identified by their approval number, and inspectors check that the installed unit matches the approved listing.

Many other parts of Florida, including Citrus County, follow the Florida Building Code's wind-zone requirements rather than HVHZ rules. A Miami-Dade NOA is still a recognized mark of tested performance, but it is not always the document required for a project outside the HVHZ. Anyone comparing products should confirm which approval their local building department accepts.

For homeowners and contractors, the NOA is the practical proof that a product was tested to a defined standard, not just marketed as hurricane resistant. You can find providers who list storm and hurricane rated work in the storm and hurricane rated category of this directory.
