Before Choosing a Plan

Start with the broader Florida ADU framework and the statewide rules that may apply.
02
Research the Locality
Check the city or county rules that may add requirements, limits, or approvals.
03
Verify the Property
Review zoning, setbacks, utilities, septic, access, and other property-specific conditions.
04
Choose the Plan
Use what you learned to narrow down the ADU plans that make sense for the site.
