Zoning & Permits
Alabama requires residential building permits through local jurisdictions. The state has adopted 2021 International Residential Code for residential construction. The Alabama Division of Construction Management oversees building codes for state buildings and certain facilities. Residential and most commercial construction is regulated at the local level. Always verify requirements with your local building department.
Off-Grid & Rural Builds
For rural builds not connected to municipal sewer, onsite sewage systems are regulated by the Alabama Department of Public Health's Onsite Sewage Division. Permits require soil testing by registered professionals, system design approval, and licensed installers. Contact your local county health department for permits, soil evaluations, and system inspections.
Energy Code & Efficiency
Alabama enforces the 2015 Alabama Residential Energy Code (based on 2015 IECC with state amendments) statewide, adopted by the Alabama Energy and Residential Codes Board. The Department of Energy provides information on Alabama's energy code adoption. Requirements address insulation, HVAC efficiency, and building envelope standards for Alabama's humid subtropical climate zones.
Local Zoning Tools
Zoning in Alabama is administered locally by municipalities and counties. The UpCodes Alabama Building Codes resource provides an overview of state building codes and agencies. Contact your local planning commission or county zoning office for site-specific dimensional requirements, setback distances, and use regulations for your property.
Tip
If you're unsure about your parcel's status—whether it requires ADPH onsite sewage permit approval, falls under specific zoning restrictions, or needs soil testing—contact your local building department or county health department directly. In Alabama, counties like Jefferson, Madison, Mobile, and Baldwin all enforce different local requirements. The resources above are a great place to start.
