Alabama adopted 2021 ICC codes (IBC/IMC/IFC updated with 2024 amendments effective March 2025). The state does NOT adopt the IECC for residential — energy code compliance for residential is through ASHRAE 90.1-2013 for commercial only. Alabama is in "Dixie Alley" — the tornado corridor running through central Alabama. The April 27, 2011 Super Outbreak killed 253 people in Alabama, leading to enhanced storm shelter requirements (ICC/NSSA-500). Baldwin and Mobile counties on the Gulf Coast have enhanced hurricane requirements (Wind Zone II, 130 mph). The New Madrid Seismic Zone affects northern Alabama. Alabama Building Commission (ABC) oversees state-owned buildings; local jurisdictions handle private construction.
