Florida Building Code 2023 Update:
What Homeowners Need to Know
Key changes affecting window and door installations across Florida — and what they mean for your upcoming project.
What Changed
Key 2023 Code Changes
Four major updates that directly affect window and door replacement projects in Florida.
Energy Code Tightening
Florida adopted the 2021 IECC energy provisions. New windows must meet a U-factor of 0.40 or lower and SHGC of 0.25 or lower in most Florida climate zones. This affects product selection for any permitted replacement.
Flood Zone Requirements
Homes in flood zones now face more stringent product testing requirements. Flood-rated impact products are now required in certain FEMA flood zones even for second-floor openings.
Installation Standards
The 2023 FBC references updated AAMA and ASTM installation standards. Fastener schedules and flashing requirements have been updated — contractors who don’t keep current risk failed inspections.
Wind Speed Maps Updated
ASCE 7-22 wind speed maps have been adopted. Some areas previously outside high-wind zones are now inside them. Check your specific address using the updated wind speed portal.
