In Alaska, building codes are adopted at the local level, meaning there is no statewide mandatory code enforcement. However, the Alaska Housing Finance Corporation (AHFC), a state agency, has adopted the 2018 International Residential Code (IRC) for residential applications and the 2018 International Energy Conservation Code (IECC) for its Building Energy Efficiency Standard (BEES). Additionally, certain codes, including the International Building Code (IBC), International Fire Code (IFC), International Mechanical Code (IMC), and International Fuel Gas Code (IFGC), are adopted under the authority of the Alaska State Fire Marshal. Local jurisdictions may operate as Deferred Jurisdictions, allowing them to enforce building codes and adopt more recent editions as needed.
