What is a Miami-Dade NOA, and why does my garage door need one?
Short answer
A Miami-Dade NOA (Notice of Acceptance) is the county's approval that a specific garage door model passed High Velocity Hurricane Zone tests for wind pressure and, if impact rated, flying debris. A replacement door in Miami-Dade or Broward needs a current NOA or a Florida Product Approval for HVHZ use. Every NOA has a number and an expiration date you can check online.
What does an NOA actually prove?
Miami-Dade County’s Product Control office reviews test reports for building products sold for use in the High Velocity Hurricane Zone (HVHZ), which covers Miami-Dade and Broward counties. When a garage door model passes, the county issues a Notice of Acceptance. For garage doors, the tests cover:
- Wind pressure: the door is loaded with uniform static air pressure, pushing in and pulling out, to its design pressure.
- Cyclic pressure: repeated pressure cycles, like the gusts of a hurricane.
- Large missile impact, for doors rated as impact resistant: a heavy projectile is fired at the door to simulate flying debris, followed by pressure cycling.
The NOA lists exactly which sizes, materials, glass, reinforcement and anchors are approved, and the design pressures each size is good for. An NOA covers the door as installed per its drawings, so installation matters as much as the door.
How do I look up an NOA number?
- Find the NOA number, written like 26-0313.16, on the quote, the label or the door paperwork.
- Go to Miami-Dade’s Product Control search (linked in sources below) and search by NOA number or manufacturer.
- Open the NOA PDF and check three things: the expiration date, that the size and model match your door, and the design pressure for that size.
For a Florida Product Approval, search the FL number on the Florida Building Commission site and confirm it says the product is approved for use in the HVHZ.
What’s design pressure, and how much do I need?
Design pressure (DP) is the wind load, in pounds per square foot (psf), the door is approved to resist. It is written as a pair, like +50/-60, for pressure pushing in and suction pulling out. The pressure your home needs depends on its location, exposure, height and the size of the opening, and the permit reviewer checks that the door’s DP meets or beats it. A wider door generally has a lower DP than a narrower one of the same model, which is why the size on the NOA must match.
Do Broward homes need a Miami-Dade NOA?
Broward is also in the HVHZ. Broward building departments accept Miami-Dade NOAs, and they also accept Florida Product Approvals that cover HVHZ use. Several Broward cities ask for a copy of the product approval with the permit application. See our garage door permit guide for Miami-Dade and Broward.
Wind-rated vs impact-rated: what’s the difference?
| Wind-load rated | Impact rated | |
|---|---|---|
| Tested for | Static and cyclic wind pressure | Wind pressure plus large missile impact |
| Holds up against | Wind pushing and pulling on the door | Wind plus debris hitting the door |
| Glass windows | Not impact glass | Impact glass, if it has windows |
| Insurance opening-protection credit | Generally doesn’t earn the credit on its own | Can count toward the credit when all openings qualify |
Ask any installer to put the NOA number, expiry date, design pressure and impact rating in writing. See garage doors and wind mitigation credits.
What should a good install quote show?
- The NOA or FL approval number and its expiration date
- Door model, size and design pressure
- Whether the door and any glass are impact rated
- Who pulls the permit, and that the permit is included
- Removal and haul-away of the old door
