New York to Montana: journeyman plumber license reciprocity
New York does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Montana'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 application with experience credit, then the Montana journeyman examinations (all states except OR, ID, ND, SD)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A journeyman licensed anywhere other than Oregon, Idaho, North Dakota or South Dakota applies under the board's 'Out of State' method (ARM 24.180.604). The applicant submits copies of every plumbing license held plus a certified verification from the state or local licensing agency stating the date of licensure and the requirements for licensure; official verifications are also required from every jurisdiction where the applicant has ever held a professional license of any kind. If the origin state's qualifications are not equivalent to Montana's five-year standard, the applicant 'will receive credit for the years required by the original state' and documents the remaining years with Experience Verification Affidavits from employing masters or contractors (W-2s and pay records may supplement them). Applicants from states with no journeyman or master licensing instead provide notarized statements from qualified individuals with direct knowledge of five years of plumbing experience. The checklist states that applicants using the out-of-state method 'will be required to sit for all the required examinations': after board approval (about 30 days) the applicant schedules with IAPMO, pays IAPMO's fee, and passes both journeyman written examinations (100 code questions plus the diagram-based former practical, now also written) with 70% each. The application fee is $220 (fee schedule effective July 11, 2026) and an optional $100 temporary practice permit allows journeyman work for a Montana master plumber for 110 days while testing.
The Montana journeyman written exam covers the 2021 UPC together with Montana statutes, board rules and Building Codes amendments; there is no separate law exam, so examLawRequired is false. ARM 24.180.604 accepts verification from a 'state or local licensing agency', so a city-issued license is considered for experience credit. The 2023 checklist and packet still print a $400 out-of-state fee and $270 exam fee; ARM 24.180.401 as amended July 11, 2026 sets both at $220. IAPMO's exam fee amount is not published on any board page. Military members, spouses and relocating veterans are licensed under MCA 37-1-147 instead and may receive a temporary license while curing deficiencies.

How Montana licenses journeyman plumbers
Montana journeyman plumber · “Journeyman Plumber”
Statewide license
Issued by Montana Board of Plumbers (Department of Labor & Industry, Business Standards Division)
Montana issues a statewide Journeyman Plumber license through the Board of Plumbers in the Department of Labor & Industry; a journeyman may work only in the employment of a licensed master plumber. A new applicant qualifies under MCA 37-69-304 with five years and 7,500 hours of legally obtained plumbing experience verified by a licensed master or plumbing contractor, or a registered apprenticeship completion certificate (approved trade-school or engineering study counts for up to two of the five years), then passes the IAPMO-administered open-book exams on the 2021 Uniform Plumbing Code with 70% on each part. Since April 11, 2026 both the written and the former practical exam are given in written format. The application fee is $220 under the fee schedule effective July 11, 2026 (the 2023 packets still print $270); IAPMO's exam fee is paid separately; a $100 temporary practice permit lets an approved exam candidate work for a Montana master for 110 days. Licenses expire every September 1, renew for $160 and require 4 hours of code-related continuing education a year. Out-of-state journeymen from Oregon, Idaho, North Dakota or South Dakota are licensed by reciprocity without the Montana exam; everyone else receives credit for the years their origin state required but must pass the Montana exams.
Why New York has nothing to transfer
New York journeyman plumber · “Journeyman Plumber (municipal; NYC registration / Westchester Journey-Level)”
Licensed by cities and counties
Issued by New York cities and counties (no statewide plumber licence)
New York has no statewide plumber licence at any level: the Department of State's Division of Licensing Services regulates 35 occupations and none of them is plumber, plumbing contractor, journeyman plumber or master plumber. Journeyman-level plumbing credentials therefore exist only where a city or county ordinance creates them, and they are not interchangeable. New York City's Department of Buildings issues a Journeyman Plumber / Fire Suppression Piping Installer registration (employees work under a licensed Master Plumber; the registration is not an independent contracting licence). Westchester County issues a Journey-Level plumber licence (exam application $25, licence and renewal $75) that is required to work as a plumber anywhere in the county, including Yonkers. Rochester publishes a Plumbing Licensing programme on its Licensed Trades page but does not list class names or fees on that page. An out-of-state journeyman plumber licence has no state-level recognition in New York; the arriving worker must satisfy the city or county where the work will be done, and in New York City that typically means working under a licensed Master Plumber while holding (or obtaining) the city journeyman registration.
How local licensing works in New York
How local licensing works. No state agency licenses plumbers in New York. Each city or county that requires a licence runs its own examining board under its own ordinance, so titles, exams and fees differ, and a licence from one jurisdiction is not automatically valid in another. There is no defaultPath and no state-to-state agreement at this level.
New York City. DOB's licence-types list includes 'Plumbing and Fire Suppression (Master and Journeyman)'. The master-plumbers page links Obtain a Journeyman Plumber / Fire Suppression Piping Installer Registration (and a separate Gas Work Qualification). The registration is person-held and is the city's journeyman-level credential; independent plumbing contracting in the five boroughs requires the Master Plumber licence (see master level). New applications go through DOB NOW (since 7 September 2021). The master written (LIC41, $585) and practical (LIC42, $530) exam fees published on the master-plumbers page apply to the Master Plumber licence, not to the journeyman registration.
Westchester County (including Yonkers). 'Plumbers and Electricians must obtain a trade license from Westchester County in order to work in the county. The first step is to apply to take the licensing examination.' Journey-Level exam application $25.00; Journey-Level licence $75.00; Journey-Level renewal $75.00; vehicle decals $5.00 each. Exam and re-examination amounts are paid to the testing company and are not listed on the fee page. Yonkers does not appear to issue a separate city plumber licence; county law requires the Westchester trade licence to work in the county.
Rochester. The Licensed Trades page lists Plumbing Licensing alongside electrical and SE/RO and routes applications to the city's Infor portal (585-428-9339). Confirm the destination city or county before working; in NYC plan to work under a Master Plumber and obtain the city journeyman registration; in Westchester apply for the Journey-Level exam.
