Alaska building departments

How permitting works in Alaska

State plan review for larger buildings; local codes for homes. For a house of one to three units outside Anchorage, Fairbanks, Juneau, and other deferred cities, there is usually no state building permit. Commercial buildings and housing of four or more units need State Fire Marshal plan approval before work starts.

A county name is only a geographic starting point. Depending on the address, a city, town, borough, township, or county office may issue your permit. How to check who issues your permit.

Alaska building codes and licensing

Residential code

No statewide residential code for one- to three-family homes; they are exempt from the state code, and local governments such as Anchorage set their own

Commercial code

2021 IBC with Alaska amendments (13 AAC 50.020), administered by the State Fire Marshal; electrical and plumbing follow state-adopted codes

Adopted by

Alaska Department of Public Safety, Division of Fire and Life Safety (State Fire Marshal) (opens in a new tab)

Outside city limits

The State Fire Marshal's office is the state building official. Outside deferred jurisdictions such as Anchorage, Fairbanks, and Juneau, it reviews plans for commercial buildings and housing of four or more units. Homes of three units or fewer are exempt from state plan review.

Contractor licensing

Contractors must register with the state before bidding or working. A general contractor needs a residential contractor endorsement, which requires an exam, to build or substantially alter (over 25% of value) a privately owned home of one to four units.

What is different in Alaska

• Before construction, remodeling, an addition, or a change of occupancy, plans must be approved by the State Fire Marshal (or a deferred local jurisdiction). Starting work without approval adds a fee equal to the plan review fee.
• Owner-builders are exempt from contractor registration but are limited to building one home, duplex, triplex, four-plex, or commercial building every two years. An owner who sells within two years must file a notice with the state.
• The state review checks fire and life safety only. It does not cover structural design or general accessibility beyond fire and life safety requirements.
