The short version
A Miami-Dade Notice of Acceptance is not a single number. It is a certification document with defined sections, and a plans examiner reads them in a specific order. The parts that get a submittal rejected are the expiration date, the design-pressure tables, and the anchorage details — not the NOA number itself.
The number gets you in the door. Everything after it is where the review actually happens. This post walks you through each field, top to bottom, so you can read an NOA the way a reviewer does.
What an NOA actually is
An NOA is issued by the Miami-Dade County Department of Regulatory and Economic Resources, Product Control Section. It certifies that a manufacturer’s system — typically a window, door, or other building-envelope product — has been tested to the Florida Building Code requirements for the High Velocity Hurricane Zone and is accepted for use in Miami-Dade and Broward.
It is not a building permit and it is not a product’s marketing sheet. It is the approval document that carries the tested performance, and the submittal package has to show that the installed condition matches what the NOA covers.
We’ve covered the difference between an NOA and a statewide Florida Product Approval — this post is about reading the NOA itself.
The NOA number
The number follows the format YY-MMDD.NN. The YY is the year the number was assigned, MMDD is the month and day, and NN is a sequence count for that day. An NOA like 21-1108.05 was the fifth NOA issued on November 8, 2021.
Two things matter here beyond recognizing the format:
- The number alone proves nothing current. A number you recognize from last year can be a version that has since been revised or renewed.
- The issuing version matters. Miami-Dade NOAs get revised and renewed, and each revision supersedes the last. An NOA number on a two-year-old submittal PDF is not automatically the current approval.
Issue and expiration dates
The NOA states an issue date and an expiration date, typically on a five-year cycle. This is the first thing a reviewer checks, and it is the most common reason a submittal is kicked back.
- Current NOA: the expiration date has not passed.
- Expired NOA: the acceptance is no longer valid. Installing a product against a lapsed approval means the product was not approved for that installation at the time of inspection.
Renewal is not automatic. The manufacturer files a renewal application, and the Product Control Section confirms the product has not changed and is not affected by code changes since the last approval. Until that renewal is issued, an NOA terminates at its expiration date.
The description and approval document
The NOA names the manufacturer and describes the specific system — for example, a “Series DH-5560 PVC Double Hung Window.” It also references an approval document: the signed and sealed drawings the engineer of record prepared for that system.
This matters more than it looks like it does. The approval document defines exactly what was tested. If the frame profile, glass make-up, or installation method on your project does not match what the approval document covers, the NOA does not apply to your condition.
Missile impact rating
The NOA states the impact rating — large and/or small missile impact resistant. This is the pass/fail outcome of the impact testing the system went through, and it has to align with where the project sits and what the code requires for that building.
Design-pressure tables
This is the section that most directly governs whether a specific window works at a specific opening. The NOA lists allowable design pressures — positive and negative, in pounds per square foot — typically organized by frame size and by glazing option.
Reading it correctly means three checks:
- Find your opening’s required design pressure on the structural drawings, not the product sheet.
- Find your window’s rated design pressure in the NOA table for that exact size and glazing make-up.
- Confirm the rating equals or exceeds the requirement.
The table gives you both signs — positive and negative — and you need both. On corner openings the negative number is usually the higher one, and it is the one that gets missed. See positive vs. negative design pressure for the full breakdown of that trap. To check whether a specific product’s NOA table clears an opening’s required pressure, run it through our free wind-load calculator.
The NOA also tells you what the pressures are based on — typically allowable stress design, with the negative loads based on structural and cyclic testing and the glass sized per ASTM E1300.
Glass make-up
The NOA specifies the exact glass that was tested — for example, a laminated make-up with a specific interlayer. If your submittal calls for a different glass than the NOA covers, the design-pressure rating on the table does not apply.
The reviewer cross-checks the glass make-up on the shop drawing against the NOA. A mismatch here does not always get caught at plan review — sometimes it surfaces at inspection, which is the expensive place for it to show up.
Anchorage details
The NOA specifies the anchorage: fastener type, spacing, edge distance, and the substrates it was tested against. This is where a system approved for a concrete opening may not be approved for the wood-framed condition on your drawings.
The approval typically lists allowable anchor groups by substrate and installation type. Your anchorage has to match one of them, and the fastener quantities have to meet the tables for the design pressure at your opening.
Frame size limits
Every NOA is tested within an envelope of sizes. A unit larger than the maximum tested width or height is outside the approval. Installations larger than the tested envelope are not covered by the NOA, regardless of how the tables read.
The labeling requirement
The NOA requires each unit to carry a permanent label stating the manufacturer, model or series, and the “Miami-Dade County Product Control Approved” statement. The label is part of the compliance chain — it is how field verification ties an installed unit back to the approval.
Conditions and restrictions
The tail of the NOA lists installation requirements, approved accessory products, and any restrictions on use. Read them. A condition that your installation violates makes the approval inapplicable to your project, even if every number above it lines up.
What a reviewer actually checks
Working top to bottom, the review is:
- Is the NOA number the current version?
- Is it still valid (expiration date)?
- Does the installed condition match the description and approval document?
- Does the design pressure rating cover the opening, with both signs?
- Does the glass make-up and anchorage match?
- Is the size within the tested envelope?
Miss any of those and the submittal comes back. The NOA is the document that makes the product eligible; the matching of the installed condition to the approval is what actually passes.
If you are running this out of a folder of PDFs and institutional memory, this is exactly the kind of review that benefits from being systematized. It is the same seam where most envelope submittals get rejected — and it is the work we do for general contractors and building-envelope subs across Miami-Dade and Broward.
