| IECC — International Energy Conservation Code | 2018 IECC — adopted by reference (with ASHRAE 62.2-2016 and Alaska-specific amendments) as the ALASKA BUILDING ENERGY EFFICIENCY STANDARD (BEES). IMPORTANT SCOPE LIMIT: this is NOT a statewide construction energy code. Alaska has no statewide mandatory energy code for private construction; BEES binds only where Alaska Housing Finance Corporation or other state financial assistance is used, and for state-funded public-building retrofits. Municipalities (e.g. Anchorage, Fairbanks, Juneau) may adopt and enforce their own energy codes locally. | 15 AAC 155.010 (Adoption of energy standard and amendments) — adopted by AHFC Resolution 18-31; effective 11/28/2018; filed with the Lieutenant Governor 1/22/2019; published Register 229 (April 2019).

| IRC — International Residential Code | NONE — ALASKA ADOPTS NO EDITION OF THE INTERNATIONAL RESIDENTIAL CODE. There is no statewide residential building code in Alaska. The State Fire Marshal's codes (13 AAC 50) adopt the 2021 IBC, IEBC, IMC, IFGC and IFC but (i) EXCEPT detached one-, two- and three-family dwellings and townhouses of three stories or fewer from the IBC entirely, and (ii) affirmatively DELETE every cross-reference to the International Residential Code from the adopted IBC, IEBC, IMC and IFGC. Residential construction of three units or fewer is governed only by municipal ordinance where a municipality has adopted and enforces one, and by nothing at all in the unorganized borough. The only statewide residential requirement of any kind is the Alaska Building Energy Efficiency Standard (BEES, 15 AAC 155.010, 2018 IECC base), and BEES binds only where AHFC or other state financial assistance is involved. | 13 AAC 50.020 through 13 AAC 50.025 (Register 244, eff. 10/28/2022; authority AS 18.70.080) — NO INTERNATIONAL RESIDENTIAL CODE ADOPTION EXISTS IN ALASKA; 13 AAC 50.020 excepts "Detached one-, two-, and three-family dwellings" and townhouses of three stories or fewer from the adopted 2021 IBC, and Chapter 1 of each adopted code is revised by deleting all references to the International Residential Code (IRC).
