Florida Building Code and Your Windows: What Homeowners Need to Know

After Hurricane Andrew devastated South Florida in 1992 — killing 65 people and causing over $27 billion in damage — the state took a hard look at why so many homes failed. The answer, in large part, was windows and doors. What followed was a sweeping rewrite of the Florida Building Code that continues to protect residents today.

Why Florida's Code Is Different

Florida operates under a statewide building code with two key wind zones:

• Wind-Borne Debris Region (WBDR) — Most of Florida within a certain distance of the coast. Any new or replacement window in this zone must be impact-rated or protected by an approved shutter system.
• High Velocity Hurricane Zone (HVHZ) — Miami-Dade and Broward counties, with the strictest requirements in the country. Products must pass a rigorous testing protocol that includes large missile impact and cyclic pressure testing.

Pinellas County (where we're based) falls within the WBDR. All windows and doors we install meet those requirements.

What "Impact Rated" Actually Means

An impact-rated window has been tested to withstand a 9-pound 2x4 fired at 50 feet per second (simulating windborne debris) without allowing penetration. After impact, it must also withstand 9,000 cycles of positive and negative pressure without failing.

This isn't marketing — these are third-party laboratory tests that every product we install has passed.

The Permit Process

Every window and door replacement in Florida requires a permit and inspection. We handle the entire process — application, scheduling, and coordination with the inspector. You don't have to do a thing except let us know your project is ready to begin.

A word of caution: if a contractor offers to skip the permit to save time or money, walk away. An unpermitted installation can void your homeowner's insurance and create serious problems when you sell your home.

What This Means for You

When we pull a permit and pass inspection, you have documentation that your windows and doors were installed to code by licensed contractors. That's your protection, your insurance company's protection, and your future buyer's protection.
