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

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

Most Florida homeowners don’t realize this: when a contractor installs a new window or exterior door on your home without pulling a permit, the legal violation sits with you, not them. Not the installer. Not the sales rep. You. It’s your name on the property record, your deed filed with Lee County, and your insurance policy that quietly has a clause about unpermitted modifications. If the unpermitted work surfaces during a home sale or a claim, the contractor is long gone and you’re holding a very expensive problem. This guide-along with our Complete Guide to Windows & Doors in Fort Myers-explains exactly how the Florida Building Code applies to window and door work here, what permits are actually required, what inspections are checking, and how you protect yourself from the start. You’ll learn the three stages of inspection, what a Notice of Commencement is and why it matters to your wallet, and how to verify a product is legally approved for your climate zone before it ever leaves the warehouse.

Quick Answer

In Florida, replacing windows or exterior doors requires a permit, and the work must comply with the Florida Building Code including wind-load, impact-ratings, and product approval requirements for your specific wind zone. In Fort Myers, that permit comes through Lee County or the city, and the work must pass three inspections: a rough-in, a product approval check, and a final. The single most important document besides the permit is the Notice of Commencement, which protects you from contractor liens if the installer fails to pay suppliers.

Florida Building Code and Window/Door Permits: Where the Requirement Actually Comes From

Florida adopted a statewide building code in 2002, consolidating what had been a patchwork of hundreds of local codes. The Florida Building Code (FBC) is updated every three years, and every edition strengthens the sections that matter most to window and door work: wind resistance, impact protection, water intrusion, and energy efficiency. The reason is not bureaucratic. Hurricane Andrew in 1992 obliterated more than 25,000 homes in Miami-Dade County, and the post-storm investigation found that a staggering portion of the damage was caused by window and door failures that allowed wind pressure inside the home. Once the building envelope is breached, internal pressurization lifts roofs off and collapses walls.

Current code requires that every replacement window and exterior door in Florida meet specific design pressure ratings based on your wind zone and exposure category. Fort Myers sits in a High Velocity Hurricane Zone. That means products must be tested and approved for the wind speeds we actually experience here, not what a factory in Ohio is comfortable selling. Impact-resistant products must pass a large-missile test. Non-impact products require shutters or other code-approved protection.

Permitting exists to verify all of this. The permit is not a tax. It’s a paper trail that forces the installer to prove the product is approved, the installation method is correct, and the finished work meets code. When we pull a permit on a window installation in Fort Myers, we are formally telling the county: inspect our work, check our products, and hold us accountable.

Lee County vs. Statewide Code: Where Local Amendments Add Requirements

The Florida Building Code establishes the baseline for every county and municipality in the state. But local jurisdictions can adopt technical amendments, and Lee County has. The county is served by the Lee County Department of Community Development, which administers permitting for unincorporated areas and, through interlocal agreements, many of our municipalities. Cape Coral, Fort Myers Beach, Sanibel, Bonita Springs, and the City of Fort Myers all have their own permitting offices, but the underlying process is similar because the code foundation is the same.

Where Lee County amendments matter for window and door work:

• Plan review requirements: Some window and door replacement projects in Fort Myers require a building plan be submitted along with the permit application, especially when the opening size changes or structural headers are being modified. A simple size-for-size replacement typically does not require full plans, but a new opening almost always does.
• Threshold requirements: Lee County enforces stricter threshold and garage floor elevation standards in some flood zones. Replacing a door in a flood-prone area may require additional documentation on the threshold height relative to base flood elevation.
• Fastener and flashing specs: Local amendments can specify minimum fastener types and lengths for wood-framed, block, and masonry installations. Inspectors in Lee County are specifically trained to look for galvanic corrosion protection on fasteners in coastal environments.
• Impact protection on all openings: Lee County is fully inside the Wind-Borne Debris Region, which means every exterior opening in a residential structure needs impact-resistant glazing, shutters, or another approved protection method. There is no partial compliance.

What does this mean for you practically? A contractor installing windows and doors here must know both the state code and Lee County’s local amendments. National chains that fly crews in for a “one week sale” often don’t. When we handle a window replacement in Fort Myers, our permit package is built for Lee County’s specific amendments because that’s the only county we work in.

What a Notice of Commencement Is and Why It Protects You

A Notice of Commencement (NOC) is a legal document filed with the Lee County Clerk of Court before construction work begins. It establishes the official start date of the project and creates a lien timeline that protects the homeowner. Here’s why it matters: if you pay a contractor and that contractor fails to pay the supplier who provided the windows, the supplier can file a lien against your house. The NOC ensures that any lien on your property is tied to work performed and documented, preventing suppliers or subcontractors from filing inflated or duplicate liens.

Under Florida law, an NOC is required for any project with a direct contract price over $7,500, including materials. Here’s what homeowners need to know:

1. File it before work starts. We file the NOC as part of the permit process. If a contractor is doing work over $7,500 and has not mentioned an NOC, that’s a red flag.
2. The NOC expires after one year, or when the work is complete. If the job runs long, the NOC may need to be extended.
3. It’s your protection against “surprise liens.” Without an NOC, a window supplier you never met could file a lien for materials you already paid for.
4. You can request copies of lien releases. When a contractor pays a supplier from your job funds, the supplier can issue a lien release. Ask for these at the end of the project.

In our experience, most Fort Myers homeowners have never heard of a Notice of Commencement until we explain it. That’s a failure of the industry, not the homeowner. Any contractor doing five-figure window or door work in Lee County should be walking you through this on day one. Ed Winslow’s name is on the business, and every permit application we file in Fort Myers includes the required NOC paperwork. It’s part of doing the job correctly.

The Three Stages of Inspection: Rough-In, Product, and Final

Once a window or door permit is issued, the county inspector will visit your property. Most homeowners are surprised that there are three inspection stages, not one. Here’s what’s actually happening at each:

Stage 1: Rough-In Inspection

This happens before the new window or door is installed in its final position, or after it is set but before trim and sealants are applied. The inspector is verifying that the rough opening is structurally sound, properly sized, and that any structural modifications, such as new headers or lintels, meet code. For impact window installations, the inspector is also checking that the fasteners match the approved installation method for that specific product.

• What they check: Opening dimensions, header size, structural condition of surrounding wall, strapping and connection points.
• What you might notice: The inspector will often arrive before the old window is fully removed or when the new unit is sitting in the opening but not fully sealed.

Stage 2: Product Approval Verification

Florida is unusual in that the product itself must carry an approval number registered with the Florida Department of Business and Professional Regulation. At the product inspection, the inspector confirms that the window or door model on your permit matches the actual product being installed. They’ll check the Florida Product Approval label, the design pressure rating, and whether the product is approved for your exact wind load requirements.

• What they check: Product approval number matches the permit application, label is present and legible, product is rated for the required design pressure.
• What you might notice: The inspector will photograph the product labels. If a label is missing or obscured, the inspection fails.

Stage 3: Final Inspection

The final inspection happens after all work is complete, including interior and exterior trim, sealants, and painting if required. The inspector is confirming that the installation matches the approved plans, all previous inspection notes have been addressed, and the home is watertight. They’ll check visible caulking and sealant joints, the operation of the window or door, and that egress requirements are met if the product is in a bedroom.

• What they check: Sealant continuity, operational function, egress compliance where applicable, final grading and threshold heights where relevant.
• What you might notice: This is the inspection where the permit gets signed off as complete if everything is done right. Minor cosmetic items are not part of this inspection, but water intrusion risk items absolutely are.

A contractor who tries to rush you through these stages, or who claims inspections are “just a formality,” is not your ally. The inspector is the one who walks away with no financial stake in your project. We welcome these inspections at Winslow Windows & Doors. When our impact window installations in Fort Myers pass, it’s a third-party confirmation of the work we stand behind. Our 36500-Day Done Right Promise is backed by the fact that every job we do has been inspected by the county, not just by us.

Florida Product Approval Numbers: Why Every Window Needs One on File

Florida is one of the only states in the country that requires every window, door, skylight, and exterior opening product to be independently tested, reviewed, and listed with a state approval number before it can be legally installed. This is called a Florida Product Approval, and it is the single most important piece of documentation for any window or door you put in your home.

The approval number is issued by the Florida Department of Business and Professional Regulation after a product passes rigorous testing, including wind-load ratings, water infiltration resistance, air leakage, and for impact products, large-missile impact testing. If a product does not have a current Florida Product Approval number, it cannot be legally installed anywhere in the state, no matter what the manufacturer or installer claims.

What to look for:

1. Ask for the FL# on any quote. Reputable products like PGT, CGI, and Therma-Tru have extensive Florida Product Approval listings. Every product we install, including Mr-Glass and our other authorized brands, carries a valid Florida Product Approval number.
2. Verify the number at floridabuilding.org. You can search the database yourself. The product’s approval must list your specific model and the design pressures required for your location.
3. Check that the product’s approval matches the permit. This is what the product inspection stage verifies. If the installer swaps in a cheaper product with a different approval number, the inspection should fail.

Why this matters in Fort Myers specifically: our region sits in a High Velocity Hurricane Zone with design wind speeds exceeding 150 mph in some exposure categories. A window approved for use in inland Orlando may be completely inadequate in Lee County. The Florida Product Approval system exists precisely because a window that fails in a hurricane is not just a broken window. It’s the opening that lets the storm inside your house.

What Happens When Unpermitted Window or Door Work Is Discovered

Unpermitted work gets discovered in three common ways: during a home sale inspection, during an insurance claim, or when a building department audits a property after a complaint or a neighboring permit application pulls your property record. Here’s what happens in each of those cases, and it is not pretty.

During a home sale

When a buyer’s inspection or a title search reveals unpermitted work, the seller has a problem. Most purchase agreements in Florida require the seller to disclose all work done on the property and to bring any unpermitted modifications into compliance. That can mean paying for a “Permit Search and Verification” from the county, scheduling a code compliance inspection, and fixing any issues the inspector finds. If the work was done decades ago and doesn’t meet current code, the repairs can be extensive. Sellers in this situation routinely pay thousands of dollars out of pocket at closing, because the alternative is losing the sale.

During an insurance claim

If an unpermitted window fails in a storm and allows water intrusion, the insurance company is within its rights to deny the claim based on a material change to the structure that was made without a permit. This is not a hypothetical. Insurers in Florida have become far more aggressive about inspecting properties after claims, and unpermitted window work is one of the first things they look for. The homeowner is then left covering the damage, the repairs, and the cost of bringing the work into compliance.

How to remediate unpermitted work

• Step 1: Stop assuming the work was done correctly. It may be fine, but you need proof, not assumption.
• Step 2: Contact the Lee County Department of Community Development or your local municipal building department and explain the situation. Ask about a “Permit Search” or “Residential Property Review.”
• Step 3: Schedule a code compliance inspection. An inspector will come out and assess the work against current code. You will receive a list of any deficiencies.
• Step 4: Repair any deficiencies, and obtain any required permits retroactively. The inspector will then sign off on the work and you’ll have a legal record of compliance.

We’ve been called in on these situations before. The best-case scenario is an afternoon inspection that verifies the work is fine. The worst case is a full re-installation because the original product never had a Florida Product Approval number. The cost of that rarely compares favorably to what a proper permit would have cost on day one.

Common Mistakes to Avoid

• Assuming a “licensed contractor” means a “permitted job.” Holding a contractor’s license and pulling a permit are not the same thing. A contractor can be properly licensed and still skip the permit to save time or hide product substitutions. Always ask to see the permit application before work starts.
• Believing “the contractor handles all the paperwork” without verifying it. Yes, the contractor is supposed to handle permits and the Notice of Commencement. But if they don’t, it’s the homeowner who faces the lien or the unpermitted-work discovery. Ask for a copy of the submitted permit and the filed NOC.
• Paying the full project cost before the final inspection is complete. A contractor who demands 100% payment before final inspection passes has no leverage to finish the job correctly. Retain at least 10% until you have a final inspection sign-off in hand.
• Accepting a quote without Florida Product Approval numbers listed. If the quote doesn’t specify which products are being installed and their approval numbers, you don’t actually know what you’re buying. We list product approval numbers on every impact window quote in Fort Myers.
• Replacing a window with “just whatever fits” to save money. A window that meets code in one wind zone may be non-compliant in Lee County. The design pressure requirements for coastal Fort Myers are not optional. A non-compliant window is as bad as no window in a hurricane.
• Ignoring the Notice of Commencement requirement for large projects. Any project over $7,500 requires an NOC. If your contractor does not file one, you lose critical lien protection. It’s a legal failing, not a paperwork nicety.
• Assuming old windows are “grandfathered” and don’t need attention. Existing windows are indeed grandfathered. But the moment they are replaced, the new product must meet current code. Grandfathering does not apply to new work.

When to Call a Professional

If your contractor is evasive about permits, tells you “we don’t need one for this job,” or says they’ll “handle it later,” you are looking at a contractor who is either uninformed about Florida law or actively avoiding inspection. Neither is acceptable. You should also call a professional if you’ve discovered unpermitted work during a home sale, or if your insurance company has flagged your property.

Frequently Asked Questions

The Bottom Line

Windows and doors in Florida are not a commodity. They’re a structural and life-safety component that is regulated by one of the strictest building codes in the country, with local amendments in Lee County that add meaningful requirements for impact protection and installation standards. The permit process is not a bureaucratic hurdle. It’s the system that makes sure the product you paid for is the product that gets installed, and that it’s installed correctly. A Notice of Commencement protects you from liens. Three inspections verify the work. Florida Product Approval numbers verify the product.
