Key Regulations

  • Florida SB 102 (Live Local Act) expanded ADU rights statewide — cities cannot impose owner-occupancy or parking minimums
  • Tampa calls larger ADUs 'Extended Family Residences' (EFR) — different permitting path
  • Max ADU size: 950 sf in most Tampa residential zones
  • Hurricane-rated construction mandatory: impact windows, tie-downs, wind-rated roof
  • Flood zone compliance critical — many Tampa lots require elevated construction
  • No owner-occupancy or parking requirements per state law

Climate & Construction Notes

Tampa's hurricane risk requires impact-rated windows and doors, wind-rated roofing, and structural tie-downs (adds $10K–$20K). Flood zone compliance may require elevated foundations. Year-round AC means energy efficiency is critical.
