Plumbing licensing
In Alaska, a plumbing business registers as a mechanical contractor with the state's professional licensing division and needs a licensed Mechanical Administrator. Journeyman plumbers hold certificates of fitness from the Department of Labor and Workforce Development.1, 2, 3
Heating and cooling licensing
Plumbing and mechanical codes
Your local building department can tell you which plumbing and mechanical codes apply where you live.
Permits to replace a water heater, furnace or AC
Alaska's state fire marshal reviews plans and issues permits for building work, but homes of three units or fewer are exempt, and some cities, including Anchorage, Fairbanks and Juneau, run their own programs. A permit for a home's equipment is a local matter.4
Backflow testing
If your home has a backflow preventer, your water utility can tell you whether it needs testing and who can test it.
