What Should You Expect During the Permitting Process for Impact Windows?
Permitting for impact window installation in Florida is not optional — it is a legal requirement tied to the Florida Building Code. The process typically involves submitting product approval documentation, signed and sealed engineering drawings, and a licensed contractor’s information to your local building department before a single window comes off the truck. Expect the permit review to take anywhere from a few days to several weeks depending on your municipality and the current volume of applications.
Why the Permit Process Is More Involved Than Most Homeowners Expect
A lot of people assume permitting is just paperwork. It is actually a series of checkpoints designed to confirm the windows you are buying meet the wind-load requirements for your specific location. South Florida sits in a high-velocity hurricane zone, which triggers stricter review standards than most other parts of the country.
What Gets Submitted to the Building Department
Your contractor files what is called a Notice of Commencement along with the product approval numbers for each window or door being installed. Those approval numbers come from the Florida Department of Business and Professional Regulation and confirm the product was independently tested to handle the wind speeds required for your area. If you are in Boca Raton, the city’s building department logs the application and assigns a permit number before any work begins. Skipping this step puts your homeowner’s insurance and your certificate of occupancy at risk.
The Inspection Side of the Process
Once installation is complete, a licensed building inspector visits the property to check the work. They look at the anchor spacing, the flashing around each frame, the condition of the buck or rough opening, and whether the installed product matches the approved permit. If everything checks out, the permit gets closed. If something is off, your contractor has to correct it before the permit closes. An open permit on a home can cause real problems when you go to sell or refinance, so closing it out matters.
This is one reason working with a licensed window contractor is worth paying attention to. Contractors who pull their own permits and coordinate inspections are protecting you, not just billing you for extra steps. You can learn more about how STS handles this process on The STS Way page.
How the Timeline Plays Out From Contract to Closed Permit
Before the Windows Are Ordered
After you sign a contract, your contractor measures each opening and places a custom order with the manufacturer. Lead times on impact-rated products currently run four to ten weeks depending on the brand and configuration. The permit application usually goes in around the same time the order is placed, so the review period overlaps with production time rather than adding to it.
After the Windows Arrive
Installation on a typical single-family home takes one to three days. The permit inspection is then scheduled, often within a week of the completed installation. For homeowners in Delray Beach and surrounding communities, the timeline is similar, though each city runs its own building department on its own schedule. You can see examples of completed projects in the STS project gallery to get a sense of the scope and scale of different jobs.

The Florida Building Commission publishes the product approval database where you can look up any approved impact-rated product by manufacturer and model number, which is a useful cross-check when comparing bids.
Related Questions
Can a homeowner pull their own permit for impact window installation in Florida?
Florida law does allow owner-builders to pull permits on their own primary residence, but impact window installation requires product-specific engineering documentation and must still pass inspection against the Florida Building Code. Most homeowners find that a licensed contractor handles this more efficiently, since contractors already have the product approval paperwork and established relationships with local inspectors.
Does a closed permit affect my home's resale value?
A properly closed permit is actually a selling point. It creates a documented record that the work was done correctly and inspected by a licensed official. Buyers and their agents routinely check for open permits, and unpermitted work can delay or derail a sale. Impact windows with a closed permit give buyers confidence in both the protection and the legal standing of the installation.
