Alabama has no statewide building code, which means tiny house regulations vary significantly by county and municipality. At the state level, Alabama follows the 2021 International Residential Code (IRC), which includes Appendix AQ permitting tiny homes, but local adoption varies widely. Many Alabama counties have no dedicated building, planning, or zoning departments, effectively leaving tiny home decisions to municipalities or allowing them by default in unincorporated areas. In these areas, tiny homes are generally permitted as long as they comply with Alabama state building codes for safety. Several counties have explicitly adopted codes that support tiny homes. Baldwin County follows the 2018 IRC including Appendix Q. Jefferson County allows accessory dwelling units up to 200 square feet. Madison County has adopted the 2018 IRC with Appendix Q. Mobile County follows the 2018 International Building Codes including Appendix Q. For tiny houses on wheels (THOWs), many Alabama counties classify them as camping trailers or recreational vehicles, which cannot be used as permanent residences. Park model tiny homes face similar restrictions in some areas but may be permitted in designated RV parks or on properly zoned lots. Common requirements across Alabama include permanent foundations for primary residences, connections to water, power, and sewage, compliance with local zoning classifications, and building permits where departments exist.
