Tampa, FL Accessory Structures: Tiny Homes (2026)

Tampa distinguishes between tiny homes on permanent foundations, which must meet the Florida Building Code and local minimum dwelling-size rules, and tiny homes on wheels (THOWs), which are treated as recreational vehicles. A tiny home on a permanent foundation can be built as an accessory dwelling unit subject to the ADU rules (up to 800 sq ft) in RS-50, RS-60, RS-75, and RS-100 districts, or as a primary dwelling if it meets the zoning district's minimum dwelling size — typically 400 square feet under recent code amendments. It must meet full residential code: egress, insulation, electrical, plumbing, and hurricane anchorage. THOWs certified as RVs (RVIA) can only be parked in licensed RV parks or on private property temporarily (typically 14 days per month) and cannot serve as permanent residences. THOWs certified to ANSI Z A119.5 Park Model standards may be allowed in manufactured-home parks but not on general residential lots. Tampa does not currently have a dedicated tiny-home zoning overlay, unlike some other Florida cities. Short-term rental of a tiny home follows Tampa's STR rules and state DBPR licensing. Composting toilets and greywater systems require Florida Department of Health approval and are generally not permitted inside city limits where sewer is available.
