Plumbing Apprenticeships in New Jersey: Programs, Requirements and How to Apply

Plumbing apprenticeships in New Jersey are registered federally.

New Jersey's HVACR and plumbing boards accept only apprenticeships approved by the U.S. Department of Labor Office of Apprenticeship (OA), and they point apprentices and sponsors to that federal office — the HVACR Board's FAQ directs sponsoring employers to email the OA representative servicing the county where the company is located.

Federally, a program is registered either by DOL's Office of Apprenticeship or by a recognized state apprenticeship agency acting for DOL; in New Jersey it is the federal office the boards point to.

The same FAQ, the only board FAQ our research found, sets the employer's role: your employer must agree to and register you with the OA, and enrolling in an HVACR school program does not automatically make you an apprentice — the registration runs through the employer, not the school.

The confirmed programs all belong to union locals — Local 9, Local 24 and Local 322, each covered below.

The United Association of New Jersey also lists locals 274 (Northern New Jersey) and 475, with an Air Conditioning & Refrigeration Division, among its members; our research did not verify those locals' apprenticeship pages, so contact them directly.

Apprentices are registered, not licensed, in New Jersey — the licence sits at the top of the ladder, not the bottom.

The state's rule is that plumbing may only be performed by a master plumber, an authorized plumbing contractor, or W-2 employees working under a master plumber's supervision, so an apprentice's legal position is that of a supervised employee.

The supervision must be constant and on-site, by a licensed master plumber or a supervisory journeyman — a journeyman who has completed the apprenticeship plus three additional years working with tools.

Two registrations are in play.

The apprenticeship itself is registered with the federal OA by your employer.

Separately, the Master Plumbers Board's fee schedule lists registration as an apprentice ($50, non-refundable) and registration as a journeyman plumber ($75, or $50 where the applicant holds prior registration).

There is no journeyman plumber licence exam — journeymen are registered with the board, and the master plumber licence is the one plumbing licence the board issues.

Our research did not confirm whether the board registrations are required of every worker or used toward the master route, so ask the board before you count on either.

Three UA locals have confirmed apprenticeship programs, each with a different status.

UA Plumbers & Pipefitters Local 9 in Englishtown runs five-year apprenticeships in three programs: plumbing, pipefitting and HVAC service.

Applications are generally accepted once a year, in person, and applicants must be 18 or older.

Pay starts at 35% of the journeyman worker's wage, with yearly increases after that.

UA Plumbers Local 24 in northern New Jersey runs an apprenticeship, but its 2026 apprentice application intake was posted as filled.

UA Local 322, whose jurisdiction covers Atlantic, Camden, Cape May, Cumberland, Gloucester, Salem and parts of Ocean and Burlington counties, was not accepting applications for its commercial/industrial apprenticeship as of September 29, 2026, and requires one year of residency in the jurisdiction.

The United Association of New Jersey also lists Locals 274 and 475 among its members; our research did not verify those locals' apprenticeship pages, so contact them directly.

Nationally, the UA says its apprenticeships are registered with DOL and typically last five years, covering plumbing, pipefitting, HVACR, welding and fire protection.

Our research verified no merit-shop apprenticeship in New Jersey by name: no PHCC or ABC chapter plumbing program appears in the sources we read, so this page cannot point you to one.

Nationally, ABC describes itself as founded on the merit shop philosophy and reports more than 24,000 members, and PHCC offers apprenticeship content through its online learning academy — but which chapters run registered plumbing programs is decided chapter by chapter and was not confirmed for New Jersey.

The door is not closed, though: employers can sponsor.

The boards accept only apprenticeships the federal OA approves, and it is the employer who agrees to sponsor and registers the apprentice — so if a contractor offers you training, the test is whether the program is registered with the OA.

Ask to see that registration before you commit.

Registered apprenticeship pairs on-the-job learning with related technical instruction.

Federally, DOL recommends a minimum of 144 hours of related technical instruction per year of apprenticeship — a recommendation, not a federal requirement — and our research did not establish whether New Jersey adds a mandate of its own, so read a program's registered standards.

Our research also did not name the New Jersey colleges or training centers that deliver classroom hours for plumbing apprenticeships, so confirm the classroom side with the program you apply to.

What a completed apprenticeship is worth is clear: the master plumber exam route takes applicants who are at least 21 and have completed a four-year USDOL-approved apprenticeship (with propane education) followed by one year and at least 1,200 hours of hands-on experience as a journeyman plumber in New Jersey.

The exam itself, its fees and licence renewal are the subject of our New Jersey plumbing licence page.

Each confirmed local opens its application window on its own calendar.

Local 9 generally accepts applications once a year, in person, from applicants 18 or older; Local 24's 2026 intake was posted as filled; and Local 322 was not accepting applications as of September 29, 2026.

Watch each local's site and apply when its window opens; expect a residency rule where one is stated — Local 322 requires one year of residency in its jurisdiction.

Once accepted, a program's probationary period, if it has one, may not exceed 25% of the program length or 1 year, whichever is shorter, and completion earns a certificate from the registration agency — a credential, not the plumbing licence, which remains the master plumber licence at the top of New Jersey's ladder.

The board's fee schedule also lists registration as an apprentice ($50, non-refundable); check with the board whether and when you need it.

On who registers you, the HVACR Board's apprenticeship FAQ — the only board FAQ our research found — says your employer must agree to and register you with the USDOL Office of Apprenticeship, and that registration does not transfer automatically if you change employers.

Its answer, verbatim:

Yes, after three years.

Installing or repairing medical gas piping in health-care, dental and veterinary facilities requires a separate State Board of Examiners of Master Plumbers certification, made under the board's medical gas piping rules, and eligible applicants include licensed masters, journeymen who completed a USDOL-approved apprenticeship, and apprentices with 3 or more years.

The certification runs on a three-year cycle: $150 for the initial certification in the first year of the cycle and $150 to renew.

For an apprentice, it is the one specialty credential the research confirms is open to you before you finish the program.
