Do You Need a Permit to Replace Windows in Florida?

If you're planning to replace windows in your Florida home, the short answer for most projects is yes — a building permit is required. Under the Florida Building Code, any exterior window replacement triggers permit requirements because the new window must be verified for wind-load compliance via a Florida Product Approval number. This rule applies statewide, from Hillsborough County to Miami-Dade County, though there are important exceptions — especially after Florida's HB 803 law took effect on July 1, 2026.

Do All Window Replacements in Florida Require a Permit?

Florida's permit requirement for window replacement turns on exactly what you're replacing:

• Replacing the entire window unit (frame and sash) in an existing opening: A window permit is required in most Florida counties. Even a like-for-like swap requires the building department to verify that the new window carries a valid Florida Product Approval number for your wind zone.
• Replacing only a broken glass pane without disturbing the frame: This is generally not a permit-required activity. Multiple Florida jurisdictions confirm that replacing a single broken pane — not the entire window unit — does not trigger a permit.
• Enlarging or shrinking a window opening: Any change to the rough opening size affects the wall structure and always requires a building permit, regardless of cost.
• Adding a window where none existed before: Also requires a permit because it modifies the building envelope.

If you're upgrading to impact-resistant windows, a permit is always required — see our full impact window permit guide for details on High Velocity Hurricane Zone rules, Miami-Dade Notice of Acceptance requirements, and more.

Does Florida's HB 803 Exemption Apply to Window Replacement?

Florida HB 803, signed by Governor DeSantis in May 2026 and effective July 1, 2026, created a permit exemption for non-structural single-family residential improvements valued under $7,500. Some window replacement projects may qualify — but it's not automatic.

A like-for-like window replacement in the same opening, with no structural changes, could fall under the $7,500 threshold exemption if the total project cost is below that limit. However, the Florida Building Code still applies even without a permit. That means replacement windows must carry a valid Florida Product Approval number, be installed per manufacturer specifications, and meet sleeping room egress requirements. Pinellas County has noted that failure to maintain exemption documentation on-site can result in a Stop Work Order.

In practice, most full-home window replacement projects exceed $7,500, making the exemption inapplicable. And even for smaller projects, many contractors prefer to pull the permit to protect themselves and the homeowner. For the full breakdown of what HB 803 covers, see our HB 803 permit exemption guide.

What Florida Product Approval Documents Do You Need?

Florida Product Approval (FPA) is the state's system for certifying that construction products — including windows and doors — meet the structural performance requirements of the Florida Building Code for the wind zone where they'll be installed. A standard window replacement permit application requires:

• Florida Product Approval number: Found on the manufacturer's documentation or searchable at floridabuilding.org. Verify it covers the correct wind-pressure rating for your county and specific location.
• Manufacturer's installation specifications: Must match the FPA and be submitted with the application so the inspector can verify the windows are installed correctly.
• Contractor information: The licensed window contractor's state license number and certificate of insurance.
• Notice of Commencement: Required for projects above your county's threshold (often $2,500); must be recorded with the county clerk before work begins.

In Miami-Dade County and Broward County — the High Velocity Hurricane Zone — windows must also carry a Miami-Dade Notice of Acceptance (NOA). Standard non-impact windows are not permitted in the HVHZ; every opening requires impact-rated glazing or an approved storm protection system.

How Much Does a Window Replacement Permit Cost in Florida?

Window replacement permits are among the more affordable permit categories in Florida. Most counties charge between $100 and $300 for a residential window replacement permit. Some counties charge a flat fee per project, while others apply a small percentage of the total project value or a per-window rate.

Your licensed window contractor typically includes the permit fee in the project quote and handles the application. For a broader look at costs across project types, see our Florida building permit costs guide. In Pinellas County, Hillsborough County, and Orange County, permit applications can be submitted through online portals, which speeds up approval.

What Are the Egress Rules for Bedroom Window Replacements?

Florida follows the International Residential Code for sleeping room egress, and when you replace a bedroom window, the new window must maintain compliant egress dimensions. The Florida Building Code requires sleeping room windows to provide:

• A minimum net clear opening of 5.7 square feet
• A minimum clear opening height of 24 inches
• A minimum clear opening width of 20 inches
• A maximum sill height of 44 inches above the finished floor

If your existing bedroom windows don't meet these dimensions and you're doing a full replacement, the permit process is your chance to bring them into compliance. Installing a non-egress window in a sleeping room is a code violation that creates liability at resale and can be flagged on a four-point inspection.

How Long Does a Window Permit Take to Get in Florida?

Window and door replacement permits are among the fastest in Florida. Most counties approve a residential window permit within 1 to 5 business days for complete applications, and many online portals offer same-day or next-day approvals. The most common delay is missing or incorrect Product Approval documentation.

Under HB 803, projects on existing single-family homes valued under $15,000 qualify for a mandatory 5-business-day initial review response from the building department. Miami-Dade County window permits typically take 3 to 5 business days due to additional HVHZ review requirements.

What Happens If You Replace Windows Without a Permit?

Skipping a required window permit in Florida creates problems that can outlast the windows themselves:

• Insurance claims denied: If your windows fail in a storm and the replacement was unpermitted, your homeowner's insurance carrier may deny the claim.
• Four-point inspection flags: Florida insurers routinely require a four-point inspection on older homes, and unpermitted windows will be flagged — potentially making the home uninsurable or raising your premiums.
• Resale complications: A title search or buyer's inspection will reveal the unpermitted work, requiring a costly after-the-fact permit or price reduction to close the deal.
• Stop Work Orders and mandatory removal: Code enforcement can require the windows to be removed and reinstalled at your expense after proper permitting.
