South Carolina to Montana: journeyman plumber license reciprocity
South Carolina 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 South Carolina has nothing to transfer
South Carolina journeyman plumber · “Journeyman plumber trade certification card (CAGC SC Trades Certification, formerly MASC) - not a state license”
Licensed by cities and counties
South Carolina has no state journeyman plumber license. The LLR Contractor's Licensing Board licenses mechanical contractors (entities qualified by an individual qualifying party) for mechanical contracting work over $10,000, including the Plumbing (PB) classification confirmed on the Board's Reciprocity/Waiver Agreements list, and the Residential Builders Commission licenses residential specialty contractors for residential work over $500; neither Chapter 11 nor Chapter 59 of Title 40 creates a journeyman or master plumber credential, so a plumber who is not a contractor works under one of those licensees with no state license. The journeyman-level credential that does exist is the trade certification card of the SC Mechanical Trades Certification Program, run since 1965 by the Municipal Association of South Carolina (the association of the state's cities) and, since January 1, 2026, by the Carolinas AGC Foundation; the program's own page says the card is not a license and must not be represented as one. Whether a card is needed depends on the city or county building department. No reciprocity or out-of-state acceptance is published for the journeyman card, so an arriving journeyman plumber should expect to apply to CAGC ($35 application, PROV exam) if a local jurisdiction or employer requires a card.
How local licensing works in South Carolina
How local licensing works. State law licenses contractors, not journeyman plumbers. S.C. Code § 40-11-30 requires a Contractor's Licensing Board license (Mechanical Contractor) for mechanical contracting work whose total cost exceeds $10,000. Chapter 59 requires a Residential Builders Commission license for residential specialty contracting work over $500. Employees of those licensees need no state plumber credential. The Contractor's Licensing Board home page lists no journeyman license.
The trades certification card. The SC Mechanical Trades Certification Program was created in 1965 by the Municipal Association of South Carolina to give municipalities a common examination and certification for the mechanical trades, including journeyman and master plumbers (as described on the electrical SC seed from the same official program pages). MASC handed the program to the Carolinas AGC Foundation on January 1, 2026; cards issued by MASC remain valid until the expiration printed on them. CAGC charges a $35 application fee ($35 to re-test), uses PROV as its exam provider, and states that the card should not be confused with the LLR mechanical contractor or residential specialty licenses and that a holder will not represent the card as evidence of a license. Journeyman plumber hours, exam outline and passing score are not published on the CAGC or MASC pages extracted. Do not assume a city-issued plumber card. Confirm with each building official whether a CAGC/MASC journeyman plumber card, a local registration, or only a licensed contractor is required to pull plumbing permits or to work as an employee. The 2026-09-15 electrical SC reading of Greenville County Building Safety and the City of Greenville Building & Permit Center did not state a journeyman card requirement for electricians; plumbing may differ.
Out-of-state journeymen. There is no state path, no defaultPath, and no agreements at this level. A city or employer that wants a CAGC card will typically require the PROV exam; out-of-state journeyman plumber licenses are not described as accepted on the official pages used here.
