An impact garage door in Miami-Dade needs a Notice of Acceptance (NOA) issued for that product, and the NOA has to match the door you are actually getting: model, size range and panel or glazing option. Most failures are not fake certificates, they are certificates for a different configuration.
What an NOA covers
The NOA is the county’s approval of a product against the High Velocity Hurricane Zone requirements: the tested design pressure, the sizes covered and the installation details. It is specific, not generic.
Three mismatches to watch for
- Size. A rating valid up to a certain width does not cover a wider door. Check the range in the document against your opening.
- Glazing or panel option. A door approved with solid panels is not automatically approved with windows, and vice versa.
- Installation method. The NOA specifies anchors and track. If the crew installs it a different way, the approval does not apply.
How to check it yourself
Ask for the NOA number before signing, look it up in the Miami-Dade product control database, and compare the product designation on the door label with the one in the document. If the installer cannot produce a number, there is no approval to check.
Why it matters beyond the inspection
An unapproved door can fail a final inspection, and it can give an insurer grounds to dispute a storm claim. The paperwork is part of the product.
