ADU State Law
What can you build in Florida?
- –Florida does not have a statewide ADU mandate. There is no state-level requirement for cities or counties to allow ADUs.
- –ADUs in Florida are regulated entirely at the local level. Some jurisdictions allow ADUs broadly, others allow them with strict conditions, and some prohibit them altogether.
- –Florida Statute 163.31771 is optional. It allows local governments to adopt ADU ordinances for affordable housing, but it does not require any jurisdiction to allow ADUs, and local governments may adopt ADU rules outside of this statute.
- –County and city rules may differ. In unincorporated areas, county zoning controls whether ADUs are allowed; within city limits, municipal zoning codes apply.
