RequiredAlaska CBPL — Mechanical Administrators P…
A mechanical contractor — one whose work involves plumbing, pipe fitting, heating, or other systems under the Uniform Plumbing, Mechanical, Solar, or Swimming Pool codes (AS 08.18.171(13)) — may be registered only if it is, or employs, a mechanical administrator licensed under AS 08.40 (AS 08.18.028), and may bid only work its administrator's category covers (12 AAC 21.600). Plumbing categories include Unlimited Commercial and Industrial Plumbing (four of the last six years as a journeyman plumber, or listed alternatives) and Residential Plumbing and Hydronic Heating (two of the last four years; 1–2 family dwellings up to three stories). The mechanical administrator license renews biennially for $200 (renewal form for Jan. 1, 2026–Dec. 31, 2027) with at least one 8-hour code workshop.
Individual plumbers need a Department of Labor certificate of fitness (AS 18.62.070(2)). A plumber journeyman certificate takes 8,000 hours under a trainee certificate plus an exam (70 percent); restricted certificates cover gas piping (Plumber Gas) and water/sewer service lines (Plumber Utility). Each costs $50 plus $200 and runs two years; journeyman renewal needs 16 hours of CE. The state plumbing code — and so the certificate requirement — does not apply in a municipality or unorganized village under 2,500 population (AS 18.60.735), and the administrator law excludes mechanical work on a 1–2 family residence not intended for sale (AS 08.40.390(b)(3)).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
The state plumbing code (AS 18.60.705) is a minimum: AS 18.60.735 preserves municipal codes no less stringent and exempts organized municipalities and unorganized villages under 2,500 population. The Mechanical Inspection Section has plumbing jurisdiction in communities of 2,500 and above and defers inspection to the Municipality of Anchorage by agreement. Administrator licensing and contractor registration are state-only; AS 08.18.061 bars local bond requirements for registered contractors.
The local offices section below names the exact permit desk for every Alaska county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
The state plumbing code and its certificate requirement do not apply in municipalities or unorganized villages under 2,500 people (AS 18.60.735).
Residential or small-commercial mechanical work of $50,000 or less in communities under 5,000 people, or more than 50 miles from a licensed administrator, is outside the administrator law (AS 08.40.390(b)(2)).
Water and sewer lines more than five feet from a building are specialty 'water and sewer' work; within five feet they are mechanical (12 AAC 21.540; AS 08.40.390(b)(4)).

Pending verification: AS 08.18 and 12 AAC 21 text was read from CBPL's compilation 'Statutes and Regulations — Construction Contractors' (rev. 09/21/2023) because akleg.gov and CBPL's web pages blocked automated fetches on 2026-10-23; amendments after September 2023 were not checked against the official code (a search found no 2025–2026 bill changing the $10,000 handyman limit or the bond amounts, and CBPL's Sept. 2025 forms match the compiled amounts) · AS 08.40 and 12 AAC 32/39 text was read from CBPL compilations dated April 2023; later amendments not checked against akleg.gov (blocked) · Mechanical contractor bond conflict: page 1 of CBPL form 08-4817 (Rev. 09/03/2025) says $5,000, while Part VII of the same form, surety bond form 08-4971, and AS 08.18.071(b)(3) say $10,000 — this record uses the statutory $10,000 · Mechanical administrator license-by-examination fees — only the by-credentials form (08-4904: $150 application + $200 license) and the 2026–2027 renewal form ($200 biennial) were retrieved; PSI exam fees not retrieved
