This bill amends section 553.73 of the Florida Statutes to enhance building requirements for certain structures in relation to impact resistance and wind resilience. It mandates that, starting with the 9th edition of the Florida Building Code, the entire building envelope—including exterior walls, roofs, doors, skylights, glazing, and glass blocks—of specific structures must meet the impact resistance standards set forth in the Florida Building Code. The structures affected include R-1 and R-2 multistory residential occupancies with sleeping units, new residences within five miles of the coastal mean high-water line, new residences in high-velocity hurricane zones, buildings designated as hurricane shelters, and rebuilt structures deemed uninhabitable or destroyed by severe weather or fire.

The bill emphasizes the use of wind-resistant materials capable of withstanding wind speeds of up to 160 miles per hour for the specified structures. This legislative change aims to improve safety and resilience against extreme weather events, particularly in hurricane-prone areas of Florida. The act is set to take effect on July 1, 2026.
