ADU rules in Riverview, FL — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Hillsborough County allows accessory dwelling units as Guest Houses and Accessory Living Quarters in most residential districts subject to size, occupancy, and family-member limits under the Land Development Code. Agricultural districts permit farm worker housing. Full independent ADU rentals are restricted.
Hillsborough County Land Development Code Part 6.01.02 permits accessory living quarters on single-family lots meeting minimum lot size, typically 800 square feet or 40 percent of primary structure, with a limit of one ADU per parcel. Occupancy is generally restricted to family members or household staff, and renting the ADU separately is prohibited in most residential zoning districts. Agricultural districts AR and AS allow farm labor housing with separate rules. Building permits, hurricane-rated construction, and septic or sewer connection are required.
Unpermitted ADU: stop-work, after-the-fact permit at double fees, potential removal. Illegal rental: code enforcement citation up to 500 dollars per violation.
