How impact fees work in Florida

Florida impact fees are one-time charges on new development, governed by Section 163.31801, Florida Statutes (the Florida Impact Fee Act). The statute requires fees to be based on the most recent and localized data, spent on the infrastructure category they were collected for, and adopted by ordinance.

Since 2021, the law also limits how fast fees can rise: increases up to 25% phase in over two years, increases of 25–50% phase in over four years, and increases above 50% are allowed only with a demonstrated extraordinary-circumstances study and at least a two-thirds vote of the governing body.

Counties and cities can both levy impact fees. Inside an incorporated city, a project typically pays the county's countywide fees plus any municipal fees the city has adopted, which is why totals differ between a city and the unincorporated county around it.
