🌴 Florida — State Guide
Florida Window Replacement Permit Requirements
Florida has more nuance around window permits than most states — not because permitting is more bureaucratic, but because of two intersecting factors unique to Florida: hurricane impact requirements and strict energy codes. A window that's legal in Georgia may not meet Florida's wind load standards, and the documentation requirements vary significantly by county.
The Florida Building Code Rule on Window Replacement
Florida Building Code (FBC) Section 105.2 lists work that does not require a permit. Included in that exemption: replacement of windows "in the same opening without structural change." This means if you are swapping an old window for a new one of the same size in the same rough opening, no permit is required in most Florida jurisdictions.
But "same opening without structural change" has important limits:
- The rough opening cannot be altered — even by an inch
- The replacement window must meet current Florida Product Approval standards (more on this below)
- If your home is in a High-Velocity Hurricane Zone (HVHZ) — Miami-Dade and Broward counties — stricter rules apply and a permit is required even for like-for-like replacement
- Some municipalities have adopted local amendments that require permits for all window replacements, regardless of the state exemption
Florida Product Approval: The Requirement Most Homeowners Miss
Even when no permit is required, Florida law requires that replacement windows carry a valid Florida Product Approval (FPA) number. Every window sold for installation in Florida must be tested and approved under the Florida Building Code's product approval system.
This matters because:
- A window that meets standard national specifications may not meet Florida's wind resistance requirements
- Installed windows without FPA numbers can create insurance issues and complicate home sales
- If a hurricane claim is filed and the windows don't have valid FPA approval, your insurer may deny wind damage claims for those openings
You can verify a window's Florida Product Approval at the Florida Building Commission Product Approval website (floridabuilding.org). Your window contractor should provide the FPA number before installation. If they cannot, that is a serious red flag.
High-Velocity Hurricane Zone (HVHZ): Miami-Dade and Broward
Miami-Dade and Broward counties sit within the High-Velocity Hurricane Zone — the most stringent wind-resistance classification in the country. In HVHZ:
- All window replacements require a permit, including like-for-like replacement
- Windows must carry Miami-Dade Notice of Acceptance (NOA) approval, which is stricter than standard FPA
- The permit process includes documentation review and a final inspection
- Contractors must be licensed by the county, not just state-licensed
Miami-Dade's permit portal (miamidade.gov/building) allows online permit applications. For standard residential window replacement in HVHZ, permit turnaround is typically 3–7 business days if submitted with complete documentation.
County-by-County Overview
| County | Like-for-Like Permit Required? | Special Requirements | Notes |
|---|---|---|---|
| Miami-Dade | Always Required | NOA approval + licensed contractor | HVHZ rules apply; online portal available |
| Broward | Always Required | NOA approval + licensed contractor | HVHZ rules apply |
| Palm Beach | Sometimes | FPA required; coastal areas stricter | Varies by municipality; check locally |
| Orange (Orlando) | Generally No | FPA required; energy compliance | FBC Section 105.2 exemption applies |
| Hillsborough (Tampa) | Generally No | FPA required; wind zone varies | Coastal areas may require permit |
| Pinellas (St. Pete) | Sometimes | FPA required; coastal flood zone | Many properties in Special Flood Hazard Area |
| Duval (Jacksonville) | Generally No | FPA required | FBC exemption applies for like-for-like |
| Lee (Fort Myers) | Varies | FPA + post-Ian flood zone reviews | Many areas designated high-wind after Ian |
| Sarasota | Generally No | FPA required | FBC exemption applies |
| Volusia (Daytona) | Generally No | FPA required; coastal areas check locally | Beachside municipalities may differ |
Florida Energy Code Requirements for Window Replacement
Florida uses the Florida Energy Conservation Code, which aligns with IECC standards. When a permit is required for window replacement, the new windows must meet minimum performance standards based on Florida's climate zones:
| Florida Climate Zone | Counties | Max U-Factor | Max SHGC |
|---|---|---|---|
| Zone 1 (Hottest) | Miami-Dade, Broward, Monroe | 0.50 | 0.25 |
| Zone 2 | Most of South/Central Florida | 0.50 | 0.25 |
| Zone 3 | North Florida (Duval, Leon, etc.) | 0.35 | 0.25 |
SHGC (Solar Heat Gain Coefficient) matters enormously in Florida. A window with high SHGC lets in more solar energy, driving up cooling costs. The 0.25 maximum is among the strictest in the country — it essentially requires Low-E coated glass in most Florida installations.
Impact-Resistant Windows: Required in Many Locations
Florida requires impact-resistant windows or hurricane shutters for all openings in buildings located in areas with design wind speeds of 130 mph or greater. This covers virtually all of South Florida and coastal areas statewide.
Impact-resistant windows are significantly more expensive than standard windows — typically $800–$1,500 per window installed versus $300–$700 for standard residential windows. However, they often qualify for Florida Citizens Insurance or private insurer discounts of 15–45% on the wind portion of your homeowners premium, which can provide substantial long-term savings.
The Wind Mitigation Inspection Connection
After installing impact-resistant windows, many Florida homeowners schedule a wind mitigation inspection. This inspection documents the wind-resistant features of your home and is submitted to your insurer for premium reduction. A qualified inspector will verify your window's impact rating, product approval number, and installation quality. The inspection typically costs $75–$150 and can save hundreds annually on insurance.
The Florida Permit Process When a Permit Is Required
- Contractor pulls the permit — In Florida, licensed contractors are typically required to pull permits; homeowners can pull their own permits but must certify they are doing the work themselves and cannot sell the home within one year
- Submit permit application with product approval numbers, window specifications, and property information
- Plans review — 1–5 business days for standard residential window work; longer in HVHZ
- Permit issued — posted at the job site
- Installation — windows installed per manufacturer's instructions and FPA requirements
- Final inspection — inspector verifies installation, product approval compliance, and flashing/waterproofing
- Certificate of completion issued and recorded
What Florida Inspectors Check
Florida window inspectors focus on:
- Florida Product Approval / NOA number matches the installed product
- Installation method matches the approval document (anchor spacing, fastener type and size)
- Flashing and waterproofing at the sill and jambs
- Proper head flashing and integration with the building's water-resistive barrier
- For impact windows: glazing intact, no chips or cracks that could compromise impact rating
- Sill pan and drainage path for water infiltration
Florida Window Permit FAQs
Yes, as an owner-builder, you can apply for a permit and do the work yourself. However, Florida law requires that you certify you will personally perform the work (not hire unlicensed help), and you cannot sell or rent the property within one year of the permit being closed. Additionally, when you eventually sell, you must disclose that owner-builder work was performed. Given the complexity of Florida's impact window installation requirements, most homeowners hire licensed contractors — especially in HVHZ where installation errors can void the product approval.
Potentially significantly. Replacing standard windows with impact-resistant windows and documenting them through a wind mitigation inspection can reduce your wind insurance premium substantially — sometimes 20–40%. Conversely, if unpermitted window work is discovered during a claim, your insurer may use it as grounds to reduce or deny the claim. Florida has had significant issues with unpermitted hurricane shutters and windows affecting claim payouts after major storms.
A Notice of Acceptance is Miami-Dade County's product approval document, which is required for all products installed in the High-Velocity Hurricane Zone. It is more stringent than the standard Florida Product Approval. You can search for NOA numbers at the Miami-Dade Building Department website. Your window manufacturer or supplier should provide the NOA number; if they cannot, the product has not been approved for HVHZ installation.
For like-for-like replacement without structural change in Hillsborough County, that is generally correct under FBC 105.2. However, verify directly with Hillsborough County Building Services before proceeding. Even without a permit, the windows must have valid Florida Product Approval numbers and meet energy code requirements. Keep documentation of the product approval numbers — you'll need them if you sell the home or file an insurance claim.
Yes, always. Adding a new window opening involves structural work (cutting through wall framing or masonry), which requires a permit in all Florida jurisdictions. The work will also require a structural review in most cases, and the new window must meet all current FBC requirements including impact resistance in applicable zones.
