Alaska Building Permit Guides

Alaska has no statewide residential building code. The state building codes are adopted by the Division of Fire and Life Safety in the Department of Public Safety. They are the 2021 International Building, Fire, Existing Building and Mechanical Codes, with Alaska amendments, and they are mandatory for commercial, public, multi-family and state-owned buildings, but they exempt residential buildings of three units or fewer. So whether a home needs a permit depends entirely on the local government: some municipalities enforce residential codes, while many boroughs and the vast unorganized areas of the state enforce none.

Three things reach across Alaska regardless of local building enforcement. A contractor needs a State of Alaska contractor licence from the Division of Corporations, Business and Professional Licensing, and a general contractor who builds a privately owned home of one to four units, or alters one by more than 25 percent of its value, also needs the residential endorsement, which requires a passed exam and a cold-climate construction course: the Alaska Craftsman Home Program, a course in arctic engineering, or an approved equivalent. The State Fire Marshal reviews plans for commercial and public buildings, residential buildings of four or more units, and fuel tank installations, except where a deferred jurisdiction runs its own review. And septic systems and rural water systems go through the Department of Environmental Conservation.

Whether a local building code is enforced where you are building

Because the state exempts small residential buildings, residential code enforcement in Alaska exists only where a local government has created it. Anchorage and the City and Borough of Juneau run their own building departments as deferred jurisdictions, administering the adopted codes locally. The Matanuska-Susitna and Fairbanks North Star boroughs have no borough-wide building code; outside cities with their own codes, such as Palmer, Fairbanks and North Pole, a home there usually needs no building permit, though zoning, driveway, floodplain and other permits may still apply. And across the unorganized borough there is often no building department at all.

Alaska licenses contractors at the state level even where it does not enforce a building code. A general or specialty contractor licence from the Division of Corporations, Business and Professional Licensing is required under the state contractor statute, with a bond and insurance. A general contractor who builds a home of one to four units, or alters one by more than 25 percent of its value, also needs the residential endorsement, which requires an exam and a cold-climate construction course such as the Alaska Craftsman Home Program or a course in arctic engineering. Electrical and mechanical contractors must have a state-licensed electrical or mechanical administrator, and electricians and plumbers need a state certificate of fitness from the Department of Labor and Workforce Development. Local rules, as in Anchorage, add to these state credentials rather than replace them.

The State Fire Marshal review and the trades

The State Fire Marshal, in the Division of Fire and Life Safety, reviews plans for commercial and public buildings, residential buildings of four or more units, and fuel tank installations. In a deferred jurisdiction, such as Anchorage or the City and Borough of Juneau, the local department runs that review instead. Electricians and plumbers need state certificates of fitness, and they work to the 2020 National Electrical Code and the 2018 Uniform Plumbing Code.

Trade work is licensed by the state whether or not a local building code applies. The 2020 National Electrical Code applies everywhere in Alaska; the 2018 Uniform Plumbing Code applies in communities of 2,500 people or more.
