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

Registered plumbing apprenticeship in Maryland is a state-administered system.

Maryland is a State Apprenticeship Agency (SAA) state: the Office of Apprenticeship, inside the Maryland Department of Labor's Division of Workforce Development and Adult Learning, oversees Registered Apprenticeship on behalf of the U.S. Department of Labor.

That role was established under the RAISE Act of 2025, succeeding the Maryland Apprenticeship and Training Program (2016–2025), and some state pages still carry the older MATP name.

Registered programs run under sponsors, and a sponsor can be a union joint apprenticeship and training committee (JATC): the one our research confirmed is the UA Plumbers and Steamfitters Local 486 JATC, which trains with the Mechanical Contractors Association of Maryland and which the state lists as one of its oldest and largest Registered Apprenticeship sponsors, registered since 1962.

A registered apprenticeship also clears a federal floor: an apprenticeable occupation must require at least 2,000 hours of on-the-job learning under the industry standard, and programs are registered by a recognized State Apprenticeship Agency acting for the U.S. Department of Labor — in Maryland, the Office of Apprenticeship.

Both, and they are separate: the apprenticeship itself is registered with the Office of Apprenticeship, while the Maryland State Board of Plumbing licenses Apprentice, Journey and Master Plumber/Gas Fitters, an apprentice must be at least 16, and Maryland plumbing apprentices must hold the board's apprentice license — $18.50 as of July 1, 2025.

Two timing rules matter while you serve: every State Board of Plumbing license expires two years from its date of issue, and an apprentice license may be renewed for only two consecutive cycles before the holder must take the journey exam, so track renewals against your program's length.

Continuing education is not part of the burden while you serve: the board's 8-hours-a-year CE rule applies to plumbing inspectors, not plumbers.

Completing the registered program earns a certificate from the registration agency — here the Office of Apprenticeship.

Our research did not find a board rule that lets a plumbing applicant skip the journey exam, so plan on the exam and confirm with the board.

The confirmed program is the UA Plumbers and Steamfitters Local 486 JATC, which sponsors registered apprenticeship together with the Mechanical Contractors Association of Maryland.

It has been a registered Maryland apprenticeship sponsor since 1962, and the state lists it as one of Maryland's oldest and largest Registered Apprenticeship sponsors.

It trains apprentices at facilities in Rosedale, in Baltimore County, Hagerstown and Seaford, Delaware.

Local 486's own FAQ describes the apprentice experience: a $25 application processing fee, a training scholarship, books you buy yourself (about $525 in year one), class two evenings a week from September to June, and union dues of $31 a month once you are placed with a participating contractor.

Nationally, the UA says its apprenticeships are registered with the Department of Labor, typically last five years, and cover plumbing among the disciplines.

Our research did not confirm any other Maryland union plumbing program, so treat Local 486 as the verified starting point and ask the Office of Apprenticeship what else is registered.

On the non-union side, our research confirmed the national associations but no specific Maryland sponsor.

PHCC — the Plumbing-Heating-Cooling Contractors Association — offers apprenticeship content through an online learning academy.

Associated Builders and Contractors (ABC) describes itself as founded on the merit shop philosophy and reports more than 24,000 members.

What we could not confirm is the Maryland layer: which, if any, Maryland PHCC or ABC chapters, or which individual employers, sponsor registered plumbing apprenticeships.

If a Maryland contractor offers to train you, the test is registration: a program becomes a registered apprenticeship when a recognized State Apprenticeship Agency registers it for the U.S. Department of Labor, and in Maryland that agency is the Office of Apprenticeship.

Ask which agency registered the program, and confirm it with the Office of Apprenticeship before you commit.

The classroom side of a registered apprenticeship is related technical instruction.

Federally, the Department of Labor recommends — but does not require — a minimum of 144 hours of it per year of apprenticeship; each program's registered standards set what it actually asks of you.

In the confirmed Maryland example, Local 486's apprentices attend class two evenings a week from September to June.

One training total the license side fixes: the journey Plumber/Gas Fitter license requires 32 hours of backflow prevention device testing training alongside the 7,500 hours under a licensed master plumber.

Our research did not confirm which Maryland community colleges, trade schools or union training centers deliver plumbing-related instruction, or whether classroom hours transfer between programs, so ask each sponsor where its apprentices take class and how the hours are documented before you sign.

You need two things: the apprentice license and a sponsor's program, and our research does not establish which to start — ask the board and the sponsor.

The license comes from the Maryland State Board of Plumbing — at least 16 years old, $18.50 as of July 1, 2025, with renewal also $18.50 — and the program comes from the sponsor: Local 486 charges a $25 application processing fee, and its application dates change from year to year, so check the JATC's own site.

Once in, a registered program must pay a progressively increasing schedule of wages tied to the skill you acquire, and a probationary period cannot exceed 25 percent of the program length or 1 year, whichever is shorter.

The finish line is the journey license: holding the apprentice license at least 4 years, 7,500 hours under a licensed master plumber, the 32-hour backflow course and a written exam — PSI administers the board's exams, and candidates upload proof of hours, backflow certification and ID to PSI.

Above journey, the master license takes 2 years as a journey, 3,750 hours under a licensed master plumber and a comprehensive written exam.

Two dated items are worth knowing.

Under the RAISE Act of 2025, the Office of Apprenticeship in the Maryland Department of Labor's Division of Workforce Development and Adult Learning became Maryland's State Apprenticeship Agency, overseeing Registered Apprenticeship for the U.S. Department of Labor and succeeding the Maryland Apprenticeship and Training Program (2016–2025) — some older pages still say MATP.

The State Board of Plumbing's fee schedule, including the $18.50 apprentice license, is published as updated July 1, 2025, so treat those figures as current to that date and confirm fees when you apply.
