Michigan journeyman plumber · “Journey Plumber”
Statewide license
Michigan issues a statewide Journey Plumber license through LARA's Bureau of Construction Codes under Article 11 of the Skilled Trades Regulation Act (2016 PA 407, MCL 339.6101 et seq.), which replaced the Michigan Plumbing Act of 2002. Local licensing is preempted: MCL 339.6125(1) says a governmental subdivision 'may not engage in or require local licensing,' so there is no separate Detroit or other city plumber license. A new applicant must be at least 18, document at least 6,000 hours over at least three years as a registered apprentice plumber under a master plumber with notarized employer letters, pay the $40 license fee with Form BCC-329A, be approved by LARA, then pass both the PSI written exam (125 questions, 180 minutes, 75% to pass, open book on the 2021 Michigan Plumbing Code; $100 fee) and LARA's hands-on practical skills exam, both on a single one-year application. The license renews annually for $40, and renewal requires a board-approved code-update course within 12 months after each state construction code change. Michigan has no reciprocity with any state; out-of-state journeymen must pass the Michigan exams, but their out-of-state experience may be credited toward eligibility after State Plumbing Board review.

Getting licensed in Michigan from scratch
No license yet, or nothing that transfers? This is how Michigan issues a journeyman plumber license to a first-time applicant.
Journey Plumber license by examination
LARA's Bureau of Construction Codes issues the Journey Plumber license to an applicant who is at least 18 and has at least 6,000 hours of experience, gained over at least three years as a registered apprentice plumber installing plumbing under the supervision of a licensed plumber. Apprentices must register with LARA within 30 days of starting work and keep the registration renewed, because time without an active registration does not count. You apply on Form BCC-329A with the $40 license fee and a notarized experience affidavit from each employer; once LARA approves the application, you must pass two exams on that same application within one year: PSI's open-book written exam and LARA's hands-on practical skills exam. Michigan has no separate law or business exam for journey plumbers.
The PSI written exam has 125 questions in 180 minutes and covers drainage, venting, fixtures, water distribution, backflow prevention, special waste systems, testing and inspection, and reading an isometric drawing. It is taken in person at a PSI test center; online testing is not offered for this exam. Allowed references are the 2021 Michigan Plumbing Code (chapter tabs only), the State Construction Code Act (1972 PA 230) and the Skilled Trades Regulation Act (2016 PA 407), bound and unmarked. The practical exam is held about once a month from February to November in Lansing, Mason, Cadillac or St. Ignace; request a date by e-mailing your name and applicant ID to [email protected] at least 30 days ahead, as dates fill up. Passing scores do not carry over to a new application. Apprentice registration expires after five years unless the apprentice has applied for the journey exam, and on the job an apprentice must work under the direct, on-site supervision of a journey or master plumber, with no more than two apprentices per plumber. Service members, veterans and their dependents who already hold an active plumbing license in another state may ask LARA to waive the exam, and the license fee is waived for them with proof of service. Questions: LARA Licensing Section, 517-241-9316.
