Plenty of Palm Coast homeowners want a straight answer on code: do you need impact glass in every opening, or can code-approved shutters check the box instead?

The phrase to search for in the code is wind-borne debris region, often shortened to WBDR.

How the Florida Building Code Applies in Flagler County

Flagler County is coastal, and significant portions of Palm Coast and Flagler Beach fall inside the wind-borne debris region as defined by the Florida Building Code and ASCE 7.

On the ground, plenty of properties near the Intracoastal and eastward land squarely in the WBDR, which you will confirm during the permit process.

On new builds, every exterior opening must be protected with tested and approved systems rated for the site’s pressures and exposure.

When replacing existing windows, the Florida Existing Building Code requires that replacements comply with current wind and impact provisions for your location.

You can comply with impact glass, or you can use non-impact glazing and install listed hurricane shutters, which you must be able to close before a storm.

Impact Windows Vs. Shutters: What You Need to Know
