City of Tallahassee simplified its rules in March 2024 to allow ADUs in ALL residential zones citywide, 2-story allowed. Long-term (30+ day) rentals OK; short-term needs a separate license and is often restricted. Unincorporated Leon County rules may differ — verify jurisdiction.

Before You Build
ADU rules are set by each county and city — Florida law (Fla. Stat. 163.31771) lets local governments allow ADUs but doesn't require it — and they can change, so always confirm the current rule with Leon County before you build.
