Window and Door Replacement Permits in Florida

Florida requires a permit for most window and door replacements — and there's a very good reason. The Florida Building Code has some of the strictest wind-load requirements in the country, and every window and door in your home plays a structural role during a hurricane. A window and door replacement permit ensures your new products meet the required wind-pressure ratings for your specific wind zone, are properly installed, and will hold up when a storm hits.

Do You Need a Permit to Replace Windows in Florida?

Yes, in nearly all cases. Whether you're replacing a single window or doing a whole-house window replacement, Florida requires a building permit. The permit covers:

• Wind-load compliance: Every window must meet the design pressure (DP) rating required for your home's wind zone and exposure category
• Florida Product Approval: Each window must have a valid Florida Product Approval (FPA) number or Miami-Dade NOA (for homes in the High-Velocity Hurricane Zone)
• Proper installation: The installation method must match the tested and approved installation instructions for that specific window product
• Energy code compliance: Replacement windows must meet Florida's energy efficiency requirements (U-factor and SHGC ratings)

The only exception in some counties is replacing a window with an identical product in the same opening with no structural changes — and even then, many counties still require a permit. When in doubt, check with your county building department in Hillsborough, Pinellas, or whichever county your property is in.

Do You Need a Permit to Replace Doors in Florida?

Yes — the same rules apply. Exterior doors (entry doors, sliding glass doors, French doors) must meet wind-load requirements and have Florida Product Approval. Interior doors generally don't require a permit unless you're changing the door size (which means modifying the structural header). Garage doors also require permits in Florida and must meet specific wind-load ratings for your wind zone.

How Much Does a Window/Door Replacement Permit Cost?

Window and door replacement permits in Florida typically cost $100 to $400, depending on the number of openings and the county:

• 1–5 windows/doors: $100–$200
• 6–15 windows/doors: $150–$300
• Whole-house replacement (15+): $250–$400

In Miami-Dade County and Broward County (the High-Velocity Hurricane Zone), fees and product requirements are stricter — expect higher fees and more documentation. Pasco County, Polk County, and Lee County are more typical. For a complete fee comparison, see our Florida building permit costs guide.

What Is Florida Product Approval and Why Does It Matter?

Florida Product Approval (FPA) is a state certification system that verifies building products meet the Florida Building Code. Every window, door, and impact-resistant product installed in Florida must have either:

• A Florida Product Approval number — listed in the state's online product approval database
• A Miami-Dade NOA (Notice of Acceptance) — required in the High-Velocity Hurricane Zone but accepted statewide
• A local product evaluation — some counties accept local evaluations for certain products

Your window contractor must include the FPA numbers on the permit application. If the products don't have valid Florida approval, the permit will be denied. This is a non-negotiable requirement — windows and doors without proper approval can fail catastrophically during a hurricane and void your insurance coverage. Related: make sure your roof also has proper product approvals if you're doing a comprehensive envelope upgrade.

What Inspections Are Required?

Window and door replacement permits in Florida typically require one or two inspections:

• Progress inspection (some counties): Verifies proper flashing and waterproofing before the exterior is finished
• Final inspection: Confirms all windows and doors are installed per the approved plans, with proper hardware, weatherstripping, and impact protection

The inspector verifies that the installed products match the FPA numbers on the permit, the installation follows the manufacturer's approved method, and the products are properly sealed against water intrusion. Florida's humid climate and driving rain make proper flashing and sealing critical.

Can You Replace Windows Yourself in Florida?

Homeowners can replace their own windows under an owner-builder permit on their primary residence. However, window installation in Florida is not a typical DIY project. The installation must follow the exact manufacturer-approved method for your product, including specific screw patterns, sealant types, and flashing details. If the installation doesn't match the approved method, the inspection will fail. Most homeowners hire a licensed window installer who handles the permit, installs the products correctly, and ensures the inspection passes.
