FAQ

Are ADUs allowed in Tampa, Florida?
Tampa permits ADUs in certain zoning districts under Chapter 27 of the City Code, typically through a Special Use approval. Florida has no statewide ADU mandate; the relevant state statute (Fla. Stat. §163.31771) is an enabling/encouraging provision, not a preemption. Confirm current eligibility with Tampa Development & Growth Management.
What are Tampa's flood zone considerations for ADUs?
Many Tampa parcels lie within FEMA Special Flood Hazard Areas; the Florida Building Code imposes elevation and floodproofing requirements in those zones. Verify flood-zone status on the FEMA Flood Map Service Center before designing an ADU.
