New Jersey to Michigan: journeyman plumber license reciprocity
New Jersey does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Michigan's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state journey plumber (all states; Michigan has no reciprocity)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Michigan does not reciprocate with any state, so a plumber licensed elsewhere must take and pass the Michigan Journey Plumber written exam and hands-on practical skills exam regardless of origin. The out-of-state license and experience serve only to establish eligibility to sit: LARA's Out-of-State License Verification instructions state that 'all applicants with out-of-state experience must be approved to sit for examination' and that applicants 'may receive credit for experience earned from other states,' which tracks MCL 339.6109 (experience 'or an equivalent of that experience requirement' shown by notarized employer statements). The applicant files Form BCC-329A with the $40 license fee, a copy of the current out-of-state license and the issuing state's licensing requirements, the Out-of-State License Verification form completed by the issuing board, and notarized letters from each employer documenting at least 6,000 hours over at least three years under licensed supervision. The State Plumbing Board reviews out-of-state applications at its quarterly meetings; once approved the applicant schedules the PSI written exam ($100, 75% to pass) and e-mails LARA to book a practical exam date (held roughly monthly, February through November), and must pass both within the one-year life of the application. There is no separate law or business exam for journey plumbers. The only exam waiver is for service members, veterans and their dependents who hold an active plumbing license in another state.
The 120-day timeline is an estimate reflecting quarterly board review of out-of-state applications plus the need to book a monthly practical exam date at least 30 days ahead. MCL 339.6115(1)(d)(i) and BCC-329A require the 6,000 hours to be gained 'as an apprentice plumber ... under the supervision of a master plumber', and the LARA page adds 'as an actively registered plumbing apprentice'; whether hours worked in another state without Michigan apprentice registration are accepted rests on the board's equivalence finding under MCL 339.6109, and no official page states how often such credit is granted. The Out-of-State License Verification form is generic to all BCC trades and its instructions were confirmed for plumbing; the LARA plumbing page itself contains no out-of-state language. No official Michigan page names any partner state for plumbing, so no agreements are authored. The former Michigan Plumbing Act (2002 PA 733, MCL 338.3511 et seq.) was repealed by 2016 PA 407; any reciprocity language attributed to MCL 338.3531 is no longer in force and was not found in Article 11.

How Michigan licenses journeyman plumbers
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.
Why New Jersey has nothing to transfer
New Jersey journeyman plumber · “Journeyman plumber (defined status under a licensed master; no statewide journeyman license)”
No individual license at this level
Issued by New Jersey State Board of Examiners of Master Plumbers (Division of Consumer Affairs)
New Jersey does not issue a statewide journeyman plumber license. The State Board of Examiners of Master Plumbers (N.J.S.A. 45:14C; N.J.A.C. 13:32) licenses the Master Plumber and requires plumbing contractors to have a licensed master as bona fide representative. N.J.A.C. 13:32-1.3 defines a 'journeyman plumber' as a person who works under a licensed master plumber or a supervisory journeyman plumber after completing a four-year U.S. DOL-approved apprenticeship (or a qualifying engineering bachelor's degree), and a 'supervisory journeyman plumber' as a journeyman with three additional years working with tools; those are experience statuses, not Board licenses. An out-of-state journeyman license therefore has nothing to transfer to in New Jersey: the arriving plumber works as a W-2 employee (or equivalent supervised worker) of a New Jersey licensed master / plumbing contractor, and the origin hours are useful mainly as documentation toward the master exam under N.J.A.C. 13:32-2.2.
How local licensing works in New Jersey
Not coded as Municipal because the state occupies the field with a statewide master license and a statewide definition of who may work as a journeyman under that master. If a municipality still issues a local journeyman or plumber card (historically some cities did so before or alongside the state master license), that card is not a New Jersey Board credential and is not verified here. Confirm locally before assuming a city exam or fee.
