Plumbing Apprenticeships in Alaska: Programs, Requirements and How to Apply

Founder, HVACHires
Last verified September 2026

Plumbing apprenticeships in Alaska start with two registrations, not one: the apprenticeship itself is registered with the U.S. Department of Labor's Office of Apprenticeship (Alaska has no state apprenticeship agency), and the apprentice holds an Alaska Plumber Trainee certificate of fitness from Mechanical Inspection.

Both come first β€” hours only count toward the 8,000-hour journeyman certificate once you are sponsored, federally registered and holding the trainee COF.

The UA locals are in Juneau, Anchorage and Fairbanks.

Licensing rules change by statute, board rule and local ordinance, and this page is career information, not legal advice. Confirm every requirement with the licensing board (or, where licensing is local, the city or county) before you apply, schedule an exam, count hours or bid a job. In Alaska, that is the Alaska Department of Labor & Workforce Development, Mechanical Inspection section.

At a glance

Apprenticeship agency

Alaska is a federal Office of Apprenticeship (OA) state: the U.S. Department of Labor's OA registers apprenticeship programs there, and Alaska has no state apprenticeship agency.

Apprentice registration

Yes β€” plumbing work requires a state certificate of fitness, and apprentices hold the Plumber Trainee COF, which needs a β€œDavis Bacon letter” proving indenture in a DOL-registered apprenticeship plus a $50 application fee and a $200 certificate fee.

Union programs

The UA's Alaska locals are Local 262 (Juneau), Local 367 (Anchorage) and Local 375 (Fairbanks); our research did not capture each local's program details, so ask the local for your area about its plumbing apprenticeship.

Merit-shop programs

No Alaska PHCC, ABC or ACCA chapter program is named in our sources.

Whichever program you join, hours only count once you are sponsored by an employer and registered in the federal Registered Apprenticeship program.

Hours toward a license

Plumber Journeyman COF: 8,000 hours of legally obtained plumbing installation work earned while holding an Alaska Trainee COF (up to 1,000 classroom hours count), then the open-book 2018 Uniform Plumbing Code exam with a 70% pass mark.

Where to start

Find an employer sponsor, get registered in the federal Registered Apprenticeship program, and apply to Mechanical Inspection for the Trainee COF β€” start with the UA local for your area or an employer running a registered program.

The Alaska plumbing license ladder

  1. Plumber TraineeEntry level

    The certificate of fitness an Alaska plumbing apprenticeship starts on: Mechanical Inspection issues it on proof of indenture in a DOL-registered apprenticeship (a β€œDavis Bacon letter”), with a $50 application fee and a $200 certificate fee.

  2. Plumber JourneymanJourneyman

    The rung an apprenticeship builds toward: 8,000 hours of legally obtained plumbing installation work earned while holding the Trainee COF, then the open-book 2018 Uniform Plumbing Code exam with a 70% pass mark.

  3. Plumber Gas (PG)Specialty

    A parallel COF class covering fuel and gas piping within property lines: 4,000 hours in the trade, at least 2,000 of them in fuel gas piping, earned while holding a Trainee COF.

Who offers plumbing apprenticeships in Alaska?

Countable plumbing apprenticeship hours in Alaska come from registered apprenticeships, and the registrar is federal: Alaska is listed under the U.S. Department of Labor's Office of Apprenticeship, not under any state apprenticeship agency, so a program becomes a registered apprenticeship when the OA registers it.

Registered programs pair on-the-job learning with related technical instruction, and an apprenticeable occupation must require at least 2,000 hours of on-the-job learning.

On the plumbing side, the sponsor is an employer by rule: Mechanical Inspection says a plumbing apprentice must be sponsored by an employer and registered in the federal Registered Apprenticeship program before any hours count.

The UA's locals in Alaska are Local 262 in Juneau, Local 367 in Anchorage and Local 375 in Fairbanks.

Our research did not compile a full roster of Alaska's registered plumbing programs; apprenticeship.gov and the OA's field offices are the places to check.

Do Alaska plumbing apprentices need to register or hold a license?

Two registrations come up in Alaska, and they are not the same thing.

The program is registered with the federal Office of Apprenticeship, because Alaska has no state apprenticeship agency.

The apprentice-level credential is the state's: Alaska requires a certificate of fitness from the Department of Labor & Workforce Development's Mechanical Inspection section to do plumbing work, and its classes are Plumber Journeyman, Plumber Gas (PG), Plumber Restricted Utility (PU) and trainee certificates.

A Plumber Trainee COF applicant must submit a β€œDavis Bacon letter” as documented proof of indenture in an apprentice plumber program accredited by the United States Department of Labor, Office of Apprenticeship, plus a $50 application fee and a $200 certificate fee.

The ordering matters: the 8,000 hours toward a journeyman COF must be legally obtained plumbing installation work earned while holding the Trainee COF, so hours logged before you hold it do not count, and maintenance hours never count.

Job sites are capped too β€” no more than two plumber trainees for every certified plumber journeyman.

Mechanical Inspection's jurisdiction covers communities of 2,500 population and above; the Municipality of Anchorage inspects under an agreement, but a state COF is still required.

β€œTo begin earning hours, you must be sponsored by an employer and registered with the federal Registered Apprenticeship Program.”

Which union programs and locals train plumbing apprentices in Alaska?

The union locals our research confirms in Alaska are the UA's three: Local 262 in Juneau, Local 367 in Anchorage and Local 375 in Fairbanks.

Nationally, the UA describes its apprenticeships as registered with the Department of Labor, typically five years long, and covering plumbing, pipefitting, HVACR, welding and fire protection β€” a national description, not a statement of what any Alaska local's program requires.

Our research did not capture the three Alaska locals' intake schedules, wages or application windows, so contact the local for your area about its plumbing program.

Whichever local you approach, the state's rule follows you in: you must be sponsored by an employer and registered with the federal Registered Apprenticeship Program to begin earning hours.

Are there merit-shop or employer plumbing programs in Alaska?

No PHCC, ABC or ACCA chapter program in Alaska is named in the sources we read β€” that is what our research shows, not proof that none exists.

Nationally, ABC describes itself as founded on the merit shop philosophy and reports more than 24,000 members, and PHCC offers apprenticeship content through an online learning academy; whether either association has an Alaska chapter program was not verified in our research.

An employer-sponsored route can still work here, but the state's rule sets the test: a plumbing apprentice must be sponsored by an employer and registered in the federal Registered Apprenticeship program before any hours count, so ask any employer who registered its program.

In Alaska the registrar is the federal Office of Apprenticeship, because the state has no apprenticeship agency.

Which schools and related-instruction providers train Alaska plumbing apprentices?

πŸ“œ 29 CFR 29.5(b)(4)

Related technical instruction is the classroom half of a registered apprenticeship, and federally, DOL recommends a minimum of 144 hours of it per year of apprenticeship β€” a recommendation, not a requirement.

Program structure varies: terms may be time-based (at least 2,000 hours of on-the-job learning), competency-based or a hybrid.

Our research did not name the Alaska schools, colleges or training centers that provide the classroom hours for the state's plumbing apprenticeship programs β€” ask each sponsor where its apprentices take class and how the hours are documented.

Alaska's own COF rules give classroom time a defined place: up to 1,000 classroom hours can count toward the 8,000-hour journeyman requirement, inside the hours that must be earned while holding a Trainee COF.

Confirm how a provider's hours map with Mechanical Inspection before you enroll.

How do you apply for a plumbing apprenticeship in Alaska?

Apply in the order the rules require.

First, find a sponsoring employer: ask the UA local for your area, or employers running registered programs.

Sponsorship unlocks the clock β€” you must be sponsored by an employer and registered with the federal Registered Apprenticeship Program to begin earning hours.

Second, apply to Mechanical Inspection for the Plumber Trainee COF with the Davis Bacon letter documenting your indenture and the $50 application and $200 certificate fees.

Third, work: only hours earned while holding the Trainee COF count toward the 8,000 the journeyman certificate requires, with no more than two trainees per certified journeyman on a site.

Federally, a registered apprentice must be at least 16 unless a higher minimum age is set by law, there is no federal maximum age, pay follows a progressively increasing schedule tied to skill with no federally set percentage steps, and probation cannot exceed 25% of the program length or 1 year, whichever is shorter.

Completion brings the registration agency's certificate β€” a credential, not the plumbing license.

Frequently Asked Questions

Do you need a license to be a plumbing apprentice in Alaska?

What you need is the Plumber Trainee certificate of fitness.

Alaska requires a state COF from Mechanical Inspection to do plumbing work, and trainee certificates are one of its classes.

The trainee COF requires a Davis Bacon letter proving you are indentured in a plumber apprenticeship accredited by the U.S. DOL Office of Apprenticeship, plus a $50 application fee and a $200 certificate fee.

Hours worked before you hold it do not count toward a journeyman COF.

How long is a plumbing apprenticeship in Alaska?

The UA describes its registered apprenticeships as typically five years, but each program's registered standards set the actual term, and our research did not capture the Alaska locals' program lengths.

Alaska's rules fix the license-side totals instead: the journeyman COF takes 8,000 hours of legally obtained plumbing installation work earned while holding a Trainee COF, and federally an apprenticeable occupation must require at least 2,000 hours of on-the-job learning.

How much do plumbing apprentices get paid in Alaska?

Our research did not confirm Alaska-specific apprentice wage figures.

Federal rules for registered programs require a progressively increasing wage schedule tied to the skill acquired, with the entry wage not below the FLSA minimum wage where applicable; the percentage steps are set by each program's standards, not by federal rule.

Ask each sponsor for its wage schedule β€” our plumbing apprentice pay guide explains how apprentice rates work.

How many plumbing apprentices can one journeyman supervise in Alaska?

On an Alaska job site there may be no more than two plumber trainees for every certified plumber journeyman.

The federal rule is separate: a program's standards must state a numeric apprentice-to-journeyworker ratio consistent with proper supervision, training, safety and continuity of employment, but the federal rule itself sets no specific number.

Alaska's two-trainee cap is the state's limit; a program's own standards may set a tighter ratio.

What happens after a plumbing apprenticeship in Alaska?

The next rung is the Plumber Journeyman COF: 8,000 hours of legally obtained plumbing installation work earned while holding a Trainee COF, then an open-book exam on the 2018 Uniform Plumbing Code with a 70% pass mark and a 30-day wait after a failed attempt.

Alaska has no state master plumber license; holding a Mechanical Administrator license alongside a trade COF functions like one.

Our Alaska plumbing license requirements page details the license rules.
