The quote arrives with a line on it that says the door is hurricane rated, and a number next to that line. Most people read the first part, feel reassured, and skip the number. The number is the useful part.
A product approval in Florida is not a marketing claim. It is a public document, anyone can look it up, and it says a great deal more than rated or not rated. Ten minutes with it before the door is ordered will tell you whether the thing on the quote is the thing your opening actually needs.
Two systems, and why Broward sees both
Florida has a statewide product approval system run through the Florida Building Commission. An approved product gets a Florida approval number, which starts with the letters FL, and the approvals can be searched on the Commission’s website.
Miami-Dade County runs its own approval process for products used in the high-velocity hurricane zone, which covers Miami-Dade and Broward. Its approval is called a Notice of Acceptance, usually shortened to NOA, and those can be searched on the county’s website.
In Broward you will see either or both referenced on a garage door. What matters is that the approval you are shown covers use in the high-velocity hurricane zone. A statewide approval is not automatically an approval for this part of the state, and the listing says whether it covers that use or not.
None of this replaces the building department. The permit application for a replacement door asks for the approval, and the reviewer checks it. Reading it yourself is a different job: making sure the door on the quote in your hand is one that will go through that check, before you have paid a deposit on it.
What the document actually tells you
It is a technical document and parts of it are dense, but four things in it are readable by anyone.
- The size range. An approval covers doors up to a maximum width and height. A sixteen-foot opening needs a door approved at sixteen feet, not the nine-foot version of the same model.
- The design pressures. The positive and negative pressures the door was tested to, usually listed against each size. Larger doors of the same model can carry lower numbers.
- Impact. Whether the door was tested for impact from wind-borne debris. Pressure and impact are separate tests, and a door can pass one without having been put through the other.
- The installation drawings. The part almost nobody reads and the part that matters most.
The drawings are the rating
An approval does not rate a door floating in space. It rates the door installed a specific way, and the drawings show that way: which track, which brackets, how many, what type of anchor, how far apart, and into what.
That last item is the one that catches people. The drawings generally distinguish between anchoring into concrete, into concrete block and into a wood buck around the opening, and they specify different fasteners and spacings for each. What is behind your jamb decides which drawing applies. An installer who has not looked at your jamb cannot know yet which one that is.
So a door with a perfectly good approval number can still be installed in a way the approval does not cover. The approval is the recipe. The installation has to follow it.
This is also where the old hardware question lives. The drawings name the tracks and brackets the door was tested with. Hanging the new door on the old track, however sound it looks, is installing it in a way the drawings do not show.
Is it current?
Approvals are not permanent. A Miami-Dade NOA carries an expiration date on its face, and products are re-approved or dropped as the code changes. When you look one up, check that it is current and that it matches the model on your quote exactly, including any suffix. A near match is a different product.
How to read yours in ten minutes
Ask for the approval number for the exact door on the quote. Search it on the state or county site. Then check four things in order: the size range includes your opening, the pressures meet what the permit calls for, impact is covered, which in Broward every garage door needs unless the opening is protected by approved shutters, and there is an installation drawing for your kind of jamb.
If you already own a rated door, the label on the inside of the end stile usually carries the manufacturer and model, and often the approval number. Keep the approval document with the house papers. It is what a buyer, an insurer or an inspector will eventually ask for.
The money question
No prices. What the approval tells you about cost is that the rating is only as good as the installation that follows the drawing, and the anchoring work is where quotes differ most.
A quote that is noticeably cheaper than the others often has the same door on it. What is usually missing is the anchoring the drawing calls for, the permit, or both. The approval number lets you ask about that directly.
It works in the other direction too. Now and then the approval shows that a lighter, less expensive model in the same range already meets the pressures your opening needs, and the door on the quote was simply the one the salesperson had in mind.
What not to buy
- Do not buy a rated door without its approval number on the quote. If nobody can produce the number, you cannot check any of the above.
- Do not buy a door approved for a smaller opening. Same model name, different product as far as the approval is concerned.
- Do not buy an installation that has not looked at your jamb. The drawing that applies depends on it.
- Do not buy pressure and assume impact. They are two tests, and the approval says which were done.
The short version
A Florida approval or a Miami-Dade NOA is public, searchable, and specific: size range, pressures, impact, and drawings for how the door must be anchored into your particular wall. The rating belongs to the door installed exactly that way.
Reading it takes ten minutes and occasionally talks people out of a more expensive door than they need. We would still rather be asked about the number than not.
