Tampa ADU — Frequently Asked Questions
Can I build an ADU in Tampa?
Only if your property is in one of Tampa's 8 designated eligible neighborhoods under RS-50, SH-RS, or RS-60 zoning. Check the official eligibility map at tampa.gov/ADU — this is your required first step. ADUs are NOT permitted citywide in Tampa. If you are outside the eligible neighborhoods, you cannot build an ADU under current Tampa rules.
What is the maximum ADU size in Tampa?
950 sq ft maximum. The maximum height is 22 ft and minimum setbacks are 3 ft on both side and rear property lines. All ADUs in eligible neighborhoods must receive Special Use permit approval before a building permit can be issued.
Do I need to live on the property to build or rent an ADU in Tampa?
Yes. Tampa requires owner-occupancy — you must live in either the primary home or the ADU. This requirement is verified at the Special Use permit stage and confirmed at each annual renewal.
Can I use my Tampa ADU as an Airbnb?
No. Tampa prohibits short-term rentals under 7 days for ADUs. The minimum occupancy period is 7 days. Long-term rentals (7+ days) are permitted in eligible neighborhoods, but the annual Special Use permit renewal is required each year to maintain rental authorization.
How long does the Tampa ADU permit process take?
8–16 months total. Two mandatory stages: (1) Special Use permit approval: 4–12 weeks — building permit cannot be submitted until this is approved; (2) Building permit review: 4–8 weeks. Annual renewal required every year after that. Confirm neighborhood eligibility at tampa.gov/ADU, then contact Tampa Zoning at TampaZoning@tampagov.net or (813) 274-3100 to begin the Special Use permit application.
