Florida Building Codes
 
 
If you are building a new structure or undertaking structural renovations to an existing structure, Florida Building Code requires that it be engineered to withstand high winds. Wind speed by itself, does not control design requirements for construction, windload does! Implementation of the Florida Building Code requires many design considerations to be taken into account to properly determine a structures windload design. These wind load requirements are not just for residences and buildings, they also apply to towers, signs, pavilions and covered walkways.

Wind load provisions of the Florida Building Code are based on the American Society of Civil Engineers Standard (ASCE) and use wind speed measurement system called "3-second peak gust". Unlike the "fastest mile wind" (highest sustained winds) commonly used by weather reports, the "3-second-peak-gust" wind speed is 20 mph higher than the "fastest-mile" wind speed.

All Wind Maps are in PDF format.
Counties Marked as "Map not available", need to make changes to their wind maps. Those Counties are Calhoun, Dixie, Flagler,Nassau. * = A current Wind map was not provided by the County, Please Contact the Local Government (Building Department) for wind speed information.

Applied Technology Council (ATC) has put together a website to determine Windspeed by Location. The purpose of the “Wind Speed Web Site” is to provide users with a site specific wind speed using the GPS coordinate system. The reason this utility is needed is that the spatial resolution of the wind speed maps that are displayed in ASCE 7 are not sufficient to determine a site specific wind speed. There are no reference city or town locations on the ASCE 7 maps and while county boundaries are shown, the resolution is affected when the maps are expanded large enough to distinguish the boundaries and approximate the city locations.

Users can retrieve wind speeds from ASCE 7-10, ASCE 7-05 and ASCE 7-93. Wind speeds are also provided for serviceability purposes for 10, 25, 50 and 100-year return periods.
