Windows & Doors Permits, Codes & Inspections in FL: What You Need to Know

Windows & Doors Permits, Codes & Inspections in FL: What You Need to Know

Florida law holds the property owner, not the contractor, ultimately responsible for making sure a permitted window or door installation passes its final inspection. If the contractor walks off the job before the inspector signs off, the permit stays open. Five years later, when you sell the house, the title company runs a lien and permit search, finds that open permit, and the sale stalls until you pay a contractor to finish the work and close it out. We’ve watched this unfold in Miami more times than we can count. This guide walks you through the permits, codes, product approvals, and inspection stages so you can verify your project is done right, not just done, and our more guides & resources cover related topics in depth.

Quick Answer

In Florida, most window and door replacements require a building permit, and in Miami-Dade County the job must also meet the High Velocity Hurricane Zone (HVHZ) requirements of the Florida Building Code. Products need a Florida Product Approval or a Miami-Dade Notice of Acceptance (NOA), the installer must be a licensed contractor, and the job isn’t legally complete until the building department issues a final approved inspection. Expect permit fees to run $150 to $600 on a typical single-opening replacement, with the whole permit-to-final-inspection cycle taking anywhere from two days to three weeks depending on the municipality and inspection backlog.

Who Is Legally Responsible for the Permit

Here’s the answer most homeowners never hear: you are. Florida Statute 489 makes the property owner the party ultimately responsible for ensuring the permit is pulled, the work is done to code, and the inspection closes out. A licensed contractor typically pulls the permit as part of the job, but if that contractor abandons the project or never schedules the final inspection, the county looks to you, not them. The open permit becomes a lien on the property.

We tell every Miami homeowner we work with the same thing: never pay the final invoice until you can see the final approved inspection in the county’s system. Not a paper copy handed to you by the crew. Not a text message saying “all done.” The actual status in the Miami-Dade permit portal reading “final approved.” That’s the only record that closes the permit and releases you from future liability.

Open permits follow the property, not the person. They don’t expire. A window permit left open in 2011 is still open in 2026, waiting to ambush a closing attorney. In our experience the most common way homeowners discover an old open window permit is during a refinance or sale, when the title company runs the search and finds it. Fixing it at that point costs more than the original job, because you’re paying a contractor to pull a new permit, re-inspect, and sometimes tear out work that was never verified.

The Florida Building Code and the HVHZ Layer

Florida runs on a single statewide building code, the Florida Building Code (FBC), currently in its 8th Edition as of 2023 with updates enforced on a rolling basis. The code is organized by discipline: the Building volume covers windows and doors, including structural loads, wind resistance, impact protection, and installation requirements. Every city and county in Florida enforces the same FBC.

Then Miami-Dade and Broward add a layer. The High Velocity Hurricane Zone (HVHZ) is a set of stricter wind and impact requirements written specifically for the two counties that catch the worst of Atlantic hurricane landfalls. Within the HVHZ, windows and doors must resist higher wind pressures, pass more rigorous missile impact testing, and carry product approvals issued under the HVHZ’s own approval system. A window that’s perfectly legal in Orlando may not be legal in Miami. Same product line, different approval documentation, different installation requirements. For a full breakdown, see The Complete Guide to Windows & Doors in Miami.

This matters when you’re comparing quotes. A contractor working in Tampa might quote you a window that carries a Florida Product Approval but no Miami-Dade NOA. It’s a fine window. It just can’t be installed in Miami-Dade County. We carry PGT and CGI product lines specifically because both manufacturers maintain current HVHZ approvals and NOAs for the South Florida market, along with CWS and ES Windows for specific architectural applications.

Miami-Dade NOA vs. Florida Product Approval: Why Both Matter

A Notice of Acceptance (NOA) is Miami-Dade County’s own product certification. Before a window or door can be legally installed in the county, the manufacturer must submit engineering calculations, test reports, and installation specifications to the Miami-Dade Product Control Division. If the product passes, the county issues an NOA number that’s tied to that specific product, that specific size range, and that specific installation method.

A Florida Product Approval (often labeled FL number) is a statewide certification issued under Florida Statute 553.842. It works the same way: the manufacturer proves through testing and engineering that the product meets the FBC’s wind and water requirements. The FL approval covers the product for use anywhere in Florida, including the HVHZ, as long as the approval specifically notes HVHZ compliance.

Here’s the part competitor pages skip. Both documents are useless if the contractor installs the product differently than the approval specifies. Every NOA and every FL Product Approval includes installation instructions: anchoring requirements, screw schedules, mullion reinforcement, sealant specifications. If the contractor installs the window with the wrong anchors or skips the mullion reinforcement, the approval is void, the inspection fails, and the warranty is dead. We’ve seen Miami homeowners pay for impact-rated windows and get units installed with non-compliant anchors because the crew didn’t read the NOA’s installation detail-exactly the kind of issue covered in our Windows & Doors Warning Signs: A Miami Homeowner’s Reference Guide. The window looks fine from the street. It isn’t fine.

Before installation day, ask your contractor for the NOA number or FL approval number for the exact product being installed. Then go to the Miami-Dade Product Control search portal or the Florida Building Code product approval database and look it up yourself. Confirm the size you’re buying falls within the approved range. It takes five minutes and catches mistakes that cost thousands to fix later.

Contractor Credentials and Manufacturer Training

In Miami-Dade County, the contractor pulling a window or door permit must hold a valid license from the Florida Department of Business and Professional Regulation (DBPR): a certified or registered general contractor, building contractor, or residential contractor, or a specialty structure contractor whose scope covers window and door work. You can verify any Florida contractor’s license at myfloridalicense.com in under a minute. The license number will tell you the license type, issue date, and whether any disciplinary actions are on file.

The HVHZ adds something most homeowners never think to ask about: manufacturer-specific installation training. Under the FBC in the HVHZ, impact windows and doors must be installed by a contractor or technician who has completed the manufacturer’s certified installer training for that product. This isn’t a courtesy. It’s a code requirement tied to the product approval. PGT, CGI, CWS, and ES Windows each run their own training programs, and they each track which contractors have completed them.

When you’re vetting a contractor in Miami, ask two questions: “Which of your technicians completed manufacturer training for the brand we’re buying?” and “Can you show me the certificate?” A legitimate contractor answers immediately. A contractor who hedges or says training doesn’t matter is telling you they don’t understand the code they’re working under. We pull the training records for every technician on a job before that technician walks through the door, because a miss here voids the product warranty and fails the inspection.

How to Use the Miami-Dade Permit Portal

The Miami-Dade County Building Department runs its permitting through a public online portal. Every homeowner should know how to use it, because it’s the only independent verification that your job was actually permitted and actually closed. Here’s the step-by-step:

1. Go to the Miami-Dade County Building Department website and open the permit search page. You’ll find it under “Permits” or “Online Services.” The direct search tool lets you query by address, folio number, or permit number.
2. Enter your street address exactly as it appears on your property tax bill. The search will return every permit on file for that property, open or closed, going back decades.
3. Find your window or door permit in the list. Look for the description field. Window and door permits are typically described as “window replacement,” “door replacement,” “impact windows,” or similar. If you don’t see a permit for your job, your contractor never pulled one.
4. Open the permit record and look at the status field. You want to see “final approved” or “closed” with a final inspection date. If the status says “inspection pending,” “issued,” or shows inspection after inspection marked as scheduled but not passed, the job is legally incomplete.
5. Check the inspection history. The record will list every inspection requested and its result: approved, failed, or partial. A failed inspection that was never reinspected is a red flag.
6. Save or print the final approved screen. Keep it with your closing documents. This is your proof, years later, that the permit was properly closed.

In our experience running Window Replacement in Miami projects, the homeowners who use this portal catch problems that would have cost them real money. A “final approved” status is the only status that matters. “Inspection scheduled” is not close. “Inspection pending” is not close. “Contractor says it passed” is not close.

What Triggers a Mandatory Window Upgrade During a Renovation

Florida’s building code has a threshold that surprises a lot of Miami homeowners mid-renovation. Here’s the rule in plain language: if you renovate more than 50% of the home’s assessed value within a 12-month period, the entire home must be brought into compliance with current code. That includes windows and doors. Your old single-pane, non-impact windows that were perfectly legal before the renovation become a code violation the moment the renovation crosses that line.

The threshold is based on the assessed value of the structure, not the market value, and not the land. A home assessed at $200,000 that undergoes $120,000 in permitted renovations just triggered the rule. Now every window in the house must meet current impact or shutter requirements for the HVHZ, and the renovation permit will not close until the windows are addressed.

This is why the order of operations matters. If you’re planning a large renovation and you know you’re approaching that 50% threshold, the smart move is to budget for window replacement as part of the project, not discover it as a surprise stop-work order. The alternative path is installing code-approved shutters over non-impact windows, which satisfies the protection requirement in many cases and costs less than full replacement. A licensed contractor or a building department plan reviewer can tell you which path applies to your specific home.

We see this most often in Miami neighborhoods like Shenandoah and the Roads, where older homes get substantial additions and renovations. The owner’s architect flags it early, or the building department flags it at plan review. Either way, it’s better to know before the drywall goes up.

The Three Inspection Stages for Window Replacement

A typical window replacement project in Miami-Dade involves three inspection stages. Each one checks something specific, and skipping any one of them leaves the permit open. Here’s what an inspector is actually looking for at each stage:

1. Rough Opening Inspection. The old window or door is out, the new unit is in the opening but not yet sealed, anchored, or trimmed. The inspector verifies the rough opening dimensions, checks the condition of the framing behind the old window, confirms any rotten or damaged framing was repaired or replaced, and verifies the opening is ready to receive the new unit per the product approval’s installation method. In Miami’s older housing stock we regularly find wood rot concealed behind the old window that has to be remediated before this inspection can pass.
2. Installation Inspection. The new window or door is fully installed: anchored, flashed, sealed, and integrated with the weather barrier. The inspector checks the anchoring pattern against the NOA or FL approval, verifies the flashing was installed in the correct shingle pattern, confirms the sealant joints are proper, and checks that the unit operates correctly. For impact products, the inspector verifies the installation matches the approved method detail for detail. If the contractor used the wrong anchors or skipped a mullion reinforcement, this is where it gets caught.
3. Final Inspection. This is the close-out inspection. The inspector verifies the work is complete, the site is clean, the old windows or doors were disposed of properly, and all prior inspection items were addressed. Once this inspection passes and is recorded, the permit status flips to “final approved” and the permit is closed. On a straightforward single-opening replacement, the final inspection often happens the same day as the installation inspection or within a day or two.

Not every municipality runs all three stages separately. Some combine the rough opening and installation inspections into one visit. But the final inspection is universal, and it’s the one that closes the permit. If your contractor tells you the job is done but the final inspection hasn’t been scheduled, the job isn’t done.

Common Mistakes to Avoid

• Paying the final invoice before the final inspection passes. The moment the contractor has your money, your leverage disappears. Hold back the final payment until the Miami-Dade portal shows “final approved.” This is the single most important rule in this entire guide.
• Buying windows without a Miami-Dade NOA or Florida Product Approval. Some online retailers sell impact-rated windows that aren’t approved for the HVHZ. They’re legal elsewhere in Florida, but Miami-Dade will fail the inspection and you’ll be stuck with non-compliant units you can’t return.
• Assuming the contractor pulled the permit. Never assume. Look it up. If no permit exists for your job, the work was done illegally, and you now own the liability. You also can’t verify the installation ever passed an inspection.
• Ignoring the 50% renovation rule during a remodel. Crossing that threshold without addressing windows and doors will stop your renovation cold. The building department cannot close your renovation permit until the entire structure meets current code.
• Skipping the manufacturer training check. In the HVHZ, impact products installed by untrained technicians are non-compliant installations, full stop. The inspection can fail on this basis, and the product warranty is void.
• Treating a failed inspection as a minor note. A failed inspection that’s never reinspected leaves your permit open. The failure itself isn’t the problem. The failure to fix the issue and reinspect is the problem. Track every inspection result through the portal until the final one reads approved.

When to Call a Professional

If you’re replacing more than one window at a time, installing impact windows or doors in the HVHZ, or renovating near the 50% compliance threshold, this is not a job to take lightly. The product approval system, the manufacturer training requirements, and the inspection protocol exist because a non-compliant opening in a hurricane is a hole in your home’s envelope. A trained professional handles the product selection against the approval database, pulls the permit, schedules every inspection, and keeps the job moving until the portal reads final approved.

The Bottom Line

Florida’s window and door code is layered: the statewide FBC, then the Miami-Dade HVHZ on top, then product-specific approval documents with installation details that carry the force of law. The property owner, not the contractor, bears final responsibility for the permitted work and its final inspection. Verify the product approval, verify the contractor’s license and manufacturer training, watch the permit portal to final approved, and never pay in full until the county says the job is closed. The west light through a properly installed window is bright and warm and worth doing right, and the paper trail proves it. Keep the records, check the portal, and you’ll never sit across from a title company explaining an open permit you didn’t know existed.
