Miami-Dade NOA Explained: What It Means for Your Windows

By the Bigfoot Windows & Roofing team — Florida State Certified General Contractor (CGC1531370), Certified Roofing Contractor (CCC1333168), Certified Residential Contractor (CRC1331693), and Specialty Structure Contractor (SCC131153098), installing and permitting HVHZ-rated windows and roofs across Miami-Dade and Broward.

Every South Florida homeowner who has bought impact windows has heard a salesperson say “Miami-Dade approved.” Few have been handed the document that proves it. That document is the Notice of Acceptance — the NOA — and in Miami-Dade and Broward it is the difference between a permit that gets issued and a job that stalls with your walls open. Understanding Miami-Dade NOA windows is the most useful homework you can do before signing a contract.

What Is a Miami-Dade NOA (Notice of Acceptance)?

A Notice of Acceptance is a product-specific approval issued by the Miami-Dade County Product Control Section — not a brand endorsement or a marketing badge. It is a controlled document naming one manufacturer, one product line, its configurations, maximum sizes, and design pressures, plus the exact installation instructions and anchor schedule the approval depends on.

Every NOA carries an issue date and an expiration date. It is a living approval that gets renewed, revised, or allowed to lapse — a product legitimately approved four years ago may have no current NOA today. A plans examiner checks whether the NOA is current on the date of submittal.

The same system governs roofing. Tile, shingles, TPO membrane, modified bitumen, and the drip edge and roof flashing details on a re-roof all trace back to product approvals and the Miami-Dade 25-7 HVHZ wind-load standard. Windows are just where homeowners meet the paperwork first.

Miami-Dade NOA vs. Florida Product Approval: What’s the Difference?

Two separate approval tracks — and confusing them is the most common mistake on homeowner-supplied paperwork.

• Miami-Dade NOA — issued by Miami-Dade County, tested to the county’s own TAS protocols, and accepted statewide.
• Florida Product Approval — issued through the Florida Building Commission with an “FL” number. It covers the whole state, but is only valid inside the High-Velocity Hurricane Zone if it was specifically evaluated for HVHZ use.

The practical rule: an FL number by itself does not prove HVHZ compliance. Some FL approvals include HVHZ; many do not. An NOA always does. On a Miami-Dade or Broward permit, a current NOA is the cleanest path through plan review — which is why the NOA vs. Florida Product Approval distinction matters more here than anywhere else.

What an NOA Actually Certifies: Impact, Wind Pressure & Water Testing (TAS 201-203)

An NOA is the summary of three punishing tests — three inspections a window must pass before it earns the paperwork.

1. TAS 201 — Large Missile Impact. Under the Florida Building Code’s HVHZ test protocol, a nominal 2×4 lumber missile weighing approximately 9 pounds (4.1 kg) is fired at the specimen at roughly 50 feet per second (see floridabuilding.org). The interlayer must hold; the assembly must not be breached.
2. TAS 202 — Uniform Static Air Pressure. The unit is loaded to its rated positive and negative design pressures and tested for air infiltration, water infiltration, and structural performance. This decides whether your window leaks in a sideways rain.
3. TAS 203 — Cyclic Wind Pressure Loading. The damaged unit is then cycled through thousands of pressure reversals simulating a storm’s duration. A window that survives impact but fails cycling is not approved.

Two things follow. Impact resistance and pressure rating are separate properties — a product can be impact-rated and still be wrong for a large opening on an exposed elevation. And the NOA governs installation, not just the unit: anchor type, embedment depth, spacing, and substrate are part of the approval. A good product installed outside its anchor schedule is non-compliant, and it gets caught at inspection.

Why HVHZ Rules Exist and Whether Your ZIP Code Is Covered

The High-Velocity Hurricane Zone entered Florida code after Hurricane Andrew, when investigators found most catastrophic residential losses started with a breached opening. Once the envelope is punctured, internal pressure spikes and the building comes apart from the inside — roof decks lift, flashing peels, and flat roofs with poorly terminated membrane fail first. FEMA’s post-Andrew building performance assessment reached the same conclusion: envelope breaches, not wind alone, drove much of the residential structural failure (fema.gov).

The answer homeowners want: the HVHZ covers all of Miami-Dade County and all of Broward County. Not the coastal strip. Not certain ZIP codes. Inland Miami-Dade, western Broward, and the barrier islands are held to the same standard. There is no inland exemption. The HVHZ is defined in the Florida Building Code (floridabuilding.org) as those counties.

Step-by-Step: How to Look Up a Miami-Dade NOA on the County’s Product Control Site

You can verify a product yourself in five minutes. No login, no fee, no contractor needed.

1. Open the Miami-Dade County Product Control Search from the county’s Regulatory and Economic Resources pages (miamidade.gov).
2. Search by NOA number if your quote lists one. NOA numbers use a date-based format — two-digit year, month and day, then a revision sequence. Type it exactly as written.
3. No number? Search by manufacturer and product category — “windows, single hung, aluminum” — and find your exact series.
4. Open the PDF and check four fields: expiration date, product description (does it match your contract?), maximum size table, and design pressure ratings.
5. Compare approved maximum width and height against your own openings. This is where mismatches hide — the series is approved, but not at the size someone measured for your living room.

A Miami-Dade County product approval search covers NOAs; the state’s Florida Product Approval database at floridabuilding.org covers FL numbers. Run whichever matches your number, and note whether HVHZ is listed as an approved use.

“Hurricane Rated” Isn’t the Same as “NOA Approved” — Here’s Why That Matters

“Hurricane rated,” “storm rated,” and “impact glass” are marketing phrases that never appear on a permit application. A product can be tested to some standard somewhere and still lack a current NOA or an HVHZ-qualified FL approval — meaning it cannot legally be installed here.

The fix is one non-confrontational question: “What is the NOA or FL number for the exact product on my quote?” A legitimate contractor answers in seconds, because that number lives on the submittal package they use every day. A vague “everything we sell is Miami-Dade approved” should slow you down.

What Happens When a Permit Gets Rejected for a Missing NOA

This rejection means the examiner could not match the product on your application to a current, applicable approval. Common causes: an expired NOA, an FL number without HVHZ coverage, a series name that does not match the approval document, oversized units, or the NOA pages simply not attached.

Timing decides the damage. At plan review it is a resubmittal and a delay. At inspection with product already installed it is far worse: a failed inspection, no certificate of completion, and a real chance that compliant units get ordered while the non-compliant ones come out. Openings sit in plywood through the new lead time.

Who’s Liable If Your Contractor Installs a Product Without a Current NOA

The licensed contractor who pulled the permit is responsible for code compliance — that is what the license means. But the exposure does not stop there, because the property is yours. Non-compliant openings surface at resale inspection, at a wind mitigation inspection when the insurance credit you were promised gets denied, and at any future permit on the address, when open or failed permits appear in county records. Chasing a contractor who has moved on is a legal problem measured in months.

How to Verify Your Contractor’s Paperwork Before You Sign a Contract

Run this list before any deposit changes hands:

• Ask for the license number and verify it is active and matched to the scope. Ours are CGC1531370, CCC1333168, CRC1331693, and SCC131153098.
• Require the NOA or FL number in writing on the proposal, tied to the specific series and configuration.
• Look up that number yourself and confirm the expiration date and the size and pressure tables.
• Confirm the contractor — not you — is pulling the permit. An “owner-builder” permit shifts code responsibility onto you.
• Ask which anchor schedule they will follow for your wall type.

How Bigfoot Windows & Roofing Handles NOA Compliance on Every Job

We do not quote a product we cannot permit. Before a proposal leaves our office, the series, configuration, and size are checked against a current NOA, and design pressures are matched to each opening’s exposure — a second-floor gable facing open water is not the same as a protected side window. On a recent Miami-Dade job we pulled a homeowner’s existing quote, ran the series number through the county’s Product Control search, and found the NOA had lapsed months earlier — we re-specified to a current approval before a single unit was ordered, which is exactly the mismatch that gets caught at plan review.

The same discipline carries into roofing: TPO membrane and modified bitumen on flat roofs, drip edge, and roof flashing are specified to current approvals and the Miami-Dade 25-7 HVHZ wind-load standard, because an approved window under a failed roof is still a flooded house. Every homeowner receives the NOA documents with their permit package, so the proof lives in your file — not just ours.
