If you are replacing windows or doors in Fort Lauderdale, Doral, Hialeah or anywhere in Broward or Miami-Dade, you are working under some of the strictest hurricane building rules in the country. Here is a plain-English look at what they require.
The High-Velocity Hurricane Zone
Florida's building code creates a High-Velocity Hurricane Zone (HVHZ) covering Miami-Dade and Broward counties. Products installed here must pass more demanding impact and pressure tests than most of the state, and installation details are held to a higher standard. Palm Beach County and the rest of Florida follow the main Florida Building Code and use Florida Product Approval instead.
Product approvals: NOA vs Florida Approved
Every impact window or door installed in the HVHZ needs a Miami-Dade Notice of Acceptance (NOA) that matches the exact product and size you are installing. This is the paperwork your building department checks. Outside the HVHZ you will see "Florida Approved" or a Florida Product Approval number. We explain the labels in "Florida Approved" vs. "Miami-Dade NOA".
Permits and inspections
- A permit is required to replace exterior windows and doors, and a licensed contractor pulls it from your city or county building department.
- Submittals usually include the product approvals, a site or opening list and installation details.
- Inspections verify the product and the anchoring. The permit closes only after the final inspection passes.
- Association approval may also be needed for condos and HOAs before the permit is submitted.
Skipping a permit can cause problems with insurance claims, a future sale and code enforcement, so it is worth doing right.
Who does what
A good installer takes care of everything on that list: confirming the approved product, preparing the permit package, scheduling inspections and cleaning up. At EZ Glazing, that is part of every job. You can read the full process in how impact windows are installed.

Why the tests are tougher here
Miami-Dade and Broward experienced some of the worst hurricane losses in U.S. history, so these counties adopted stricter standards than most places. The testing protocols require products to withstand large-missile impact and strong cyclic pressures, and installation details are reviewed more closely by building officials.
What a typical permit package looks like
- Product approvals for each window and door type and size.
- Installation details showing anchors and spacing.
- Opening schedules (sizes and locations).
- Contractor license and insurance.
City vs county rules
Many municipalities in the two counties have their own building departments, and procedures vary. Some use online portals, others require paper submittals. A contractor who regularly works in your city will know the process.
Inspections you may see
Depending on the municipality, you may have an inspection before the trim goes on and a final inspection at the end. Keep access clear and keep your paperwork nearby.
What homeowners should do
- Choose a licensed contractor experienced with your city.
- Ask which product approvals will be used.
- Keep copies of the permit and final inspection.

Frequently misunderstood points
- "Any impact window is fine." Not true. The exact product and size must match a valid approval for your county.
- "The glass is what is tested." The whole assembly is tested: glass, frame, anchors and hardware.
- "A permit is optional." Permits are required for window replacement in most municipalities.
- "My old windows are grandfathered forever." They may stay unless you replace them, but replacements must meet current rules.
An illustrative example: a Fort Lauderdale replacement
To make the process concrete, imagine a homeowner who replaces ten windows and a slider. Her contractor submits the permit with approvals for each product and size. The city reviews the package and issues the permit. After installation, the inspector verifies product labels, anchoring and sealant, then closes the permit. The homeowner keeps the documents and later uses them for a wind mitigation inspection and her insurance quote. The process is the same in Miami-Dade, with its own forms and local procedures.
How to prepare
- Ask for the product approval numbers on your quote.
- Keep the permit card visible during the work.
- Be available for inspection or give access.
- Save the final inspection record.
Frequently Asked Questions
Do I need a permit to replace windows in Broward or Miami-Dade?
Yes. Window and door replacement requires a permit and final inspection. A licensed contractor should pull it.
What is the High-Velocity Hurricane Zone?
The HVHZ covers Miami-Dade and Broward counties and has the strictest product testing and installation rules in Florida.
What is a Miami-Dade NOA?
A Notice of Acceptance is the product approval that shows a window or door has passed HVHZ testing. Installers should provide it for your permit.
Do the rules differ in Palm Beach County?
