Window Replacement · Martin County, Florida
Permit required
In Florida, a Window Replacement requires a building permit.
Most of Martin County lies in Florida's Wind-Borne Debris Region (within a mile of the coast at 130+ mph, or anywhere at 140+ mph; here around 165-170 mph), so a permit is required to replace windows and the new windows must be impact-rated or protected by approved hurricane shutters, carrying a Florida Product Approval. Under the 25% rule, replacing more than 25% of your home's total glazed area within 12 months forces all new windows to meet current impact standards. This is one tier below the HVHZ in Miami-Dade and Broward, which require a Miami-Dade NOA. Plans are reviewed under the Martin County (FBC WBDR) code (IRC 2023 FBC); apply through Martin County Building Department before work begins.

Retrofit windows (inserting into existing frames) often do not require a permit, but new construction windows or altering the wall structure almost always requires an inspection.
With a population of around 162,176 residents, Martin County generally runs a more streamlined permitting process than major urban hubs.
Code Compliance & Inspections
Because Florida sits in a hurricane-prone zone, the Florida Building Code (FBC) requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
Concurrent Permits & HOAs
For Martin County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Window Replacement than the county itself.
Zoning & Cost Factors
Florida's building codes are some of the strictest in the nation regarding wind resistance and hurricane protection, overriding many local zoning leniencies. Fortunately, Florida maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What happens if I build a Window Replacement without a permit in Martin County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own Window Replacement permit in Florida?
Yes. Florida generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Florida Building Code (FBC).
