Miami-Dade NOA vs. Florida Product Approval: what's the difference?
A plain-English explanation of the Miami-Dade NOA and the statewide Florida Product Approval — what each one is, how they differ, and which one your contractor needs to pull a permit on your home.
What is a Miami-Dade NOA?
A Miami-Dade NOA (Notice of Acceptance) is a document issued by the Miami-Dade County Product Control Section certifying that a specific building product — a window, shutter, door, roof system, or fastener — has been tested to the High-Velocity Hurricane Zone (HVHZ) standards and is approved for installation in HVHZ jurisdictions. The HVHZ covers Miami-Dade and Broward Counties. NOA testing is stricter than statewide testing: higher design pressures, more cyclic pressure cycles, and a large missile impact test using a heavier projectile.
What is a Florida Product Approval?
A Florida Product Approval (often shortened to FL # or FL Approval) is the statewide equivalent, administered by the Florida Building Commission. It certifies that a product meets the Florida Building Code's structural and impact requirements for use anywhere in Florida outside the HVHZ. A product can carry only an FL Approval, or it can carry both an FL Approval and a Miami-Dade NOA — many manufacturers pursue both so their product can be sold statewide and in HVHZ.
What's the actual difference?
Two things. First, geographic scope: NOA is HVHZ (Miami-Dade and Broward); FL Approval is everywhere else in Florida. Second, test stringency: NOA testing is more aggressive on missile impact and pressure cycling. A product with an FL Approval is not automatically NOA-approved — many statewide-approved products were never submitted for NOA testing. A product with an NOA is generally also FL-approved (or easily can be), because clearing the NOA bar clears the FL bar.
Which one do I need?
It depends on the county the home is in. If you're in Miami-Dade or Broward, the building department will require an NOA on every product going into the building envelope — windows, doors, shutters, roofing, fasteners. If you're anywhere else in Florida (Palm Beach is outside HVHZ despite being adjacent, plus the entire west coast, Central Florida, and the Panhandle), an FL Product Approval is what your contractor needs. Asking for an NOA in Central Florida isn't wrong — it just isn't required, and limiting yourself to NOA-only products in a non-HVHZ market unnecessarily narrows your choices and raises your price.
How do I find the NOA or FL number for a quoted product?
Every legitimate quote should reference the specific product line, model, and either the NOA number or the FL Approval number. You can verify both online — Miami-Dade publishes its NOA database, and the Florida Building Commission publishes the FL Approval database. Look for the expiration date (NOAs and FLs are time-limited and have to be renewed) and the specific configuration that was approved (size limits, glass thickness, frame material). A 'NOA on file' that doesn't match your opening size or configuration is useless when the inspector comes out.
Why does this matter at the permit?
The product approval is what lets the permit get pulled and closed. An installer who can't produce a current NOA (in HVHZ) or a current FL Approval (statewide) for the exact product being installed can't legally close the permit — and an open permit follows the property at sale. This is one of the most common reasons we tell homeowners to ask for permit closeout paperwork at the end of the job, not just the pulled permit at the start. See our contractor screening guide for the full ask-list.
