Tiny home rules in Tuscaloosa, AL — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Tuscaloosa's adopted Zoning Ordinance has no "tiny house" category; a tiny home is governed by ordinary dwelling and accessory-structure rules. A permanent-foundation tiny house must meet single-family dwelling standards and the Alabama building code, and a second small dwelling on a lot is limited by the ADU rule (RA-1/RA-2 only under Sec. 24-55(4)).
There is no current Tuscaloosa ordinance that specifically permits or defines a "tiny house"; the term appears only in the city's unadopted zoning-rewrite draft. Under the rules in force, a tiny home is treated like any other dwelling. If it is placed on an engineered permanent foundation and built to the Alabama building code, it is regulated as a single-family detached dwelling and must satisfy the lot size, setbacks, and other dimensional standards of its zoning district. A tiny home cannot lawfully be added as a second dwelling unit on a lot that already has a house unless the lot is in the RA-1 or RA-2 district, where accessory dwelling units are permitted under Sec. 24-55(4). Tiny homes on wheels (RVs/park models) are not permitted as permanent dwellings on a typical residential lot and would generally only be allowed in a licensed mobile-home or RV park under the city's mobile-home park provisions. There is no minimum-square-footage exemption that lets a movable tiny house sidestep zoning. The proposed zoning rewrite would define a tiny house (e.g., under 400-600 square feet) and apply single-family standards to foundation-built units, but that draft is not adopted. Anyone considering a tiny home should verify district rules and dwelling standards with the Office of Urban Development.
Placing a tiny home as an unauthorized second dwelling, or living in a tiny home on wheels outside a licensed park, is a zoning violation. Enforcement may include removal orders, the Chapter 24 penalty (Sec. 24-203), and the general penalty in Sec. 1-8 (up to $500 and/or six months under Ala. Code §§ 11-45-1, 11-45-9).
