Some RestrictionsGarage Conversions
Tuscaloosa does not have a stand-alone garage-conversion ordinance. Converting a garage into living space is treated as a change to the dwelling and, if it adds a separate unit, runs into the ADU limits of Chapter 24 (allowed only in RA-1/RA-2 under Sec. 24-55(4)). A building permit is required, and lost parking must still meet district standards.
