New 2021 Florida Wind & Wind-Borne Debris
Building Code Requirements
Florida’s residential wind and wind-borne debris regions change frequently. The 2021 requirements are essentially the same as those made in 2012 which significantly enlarged and upgraded wind zone areas and the specification for engineering and fenestrations (windows & doors). Many other coastal states and Caribbean countries who follow Florida’s lead on building codes have also implemented similar changes.
The map at right shows the current wind and windborne-debris regions. The dark areas are those requiring high impact missile-resistant glass. Most noteworthy of the changes is that the previous maximum windload requirement in Florida was 150 mph in The Keys. The current code raises that to 180 mph and increases wind loads for many counties below mid-state from 100 mph to 140 mph and up. Additionally, areas requiring much more expensive high impact, missile resistant windows have nearly doubled and are no longer primarily in coastal areas.
