Tennessee to Vermont: master plumber license reciprocity

Vermont issues a statewide Master Plumber license (ledger code PM) through the Plumber's Examining Board in the Division of Fire Safety. A master, as a business, installs plumbing systems, hires people to do plumbing work, or supervises journey and apprentice plumbers. A new applicant must document having held a valid Vermont journeyman plumber's license for at least 12 months, or equivalent training and experience in or outside Vermont acceptable to the Board, then pass the master examination; the two-year license fee is $120 (26 V.S.A. ss. 2191, 2193(c)). Out-of-state masters use the same no-exam statutes as journeymen: uniform endorsement after three years licensed in good standing in another U.S. jurisdiction (s. 2194(a)(2)), or reciprocity without examination if the origin state or municipality had equivalent standards and grants Vermont licensees a like exemption (s. 2194(a)(1)). DFS plumbing pages name no partner states. Masters and journeymen are exempt from specialist license fees. Licenses last two years with eight hours of Board-approved CE per cycle plus the Energy Goals module. Work on installations subject to Board rules also requires a validated work notice and inspection fees, which are separate from the license.

Tennessee does not issue a master plumber license. The state-level plumbing credentials are (1) the Limited Licensed Plumber (LLP), a personal license for work under $25,000 where the Division of Fire Prevention inspects, which the Board does not treat as a master equivalent and for which it has no exam-waiver agreements, and (2) a contractor license with the CMC-A (plumbing) or CMC (full mechanical: plumbing and HVAC) classification, issued to a business that names a qualifying agent and required for plumbing projects of $25,000 or more. CMC-A and CMC candidates need Board pre-approval ($50) before the plumbing or full-mechanical trade exam; every contractor also takes the Tennessee Business and Law exam (Prov from 2026-07-01; scores typically valid two years). Initial contractor application fee $250. The Board's trade-exam-waiver form lets a contractor whose origin board verifies a comparable plumbing or mechanical exam skip the Tennessee trade exam but not Business and Law, and it cannot be used for the LLP: Ohio plumbing maps to CMC-A, South Carolina plumbing to CMC-A, and Louisiana, Mississippi and West Virginia mechanical licenses to CMC. That waiver is contractor-to-contractor only (Ohio's OCILB listing of Tennessee as a plumbing-contractor partner is the same relationship from Ohio's side). Master plumber licenses proper exist only locally; Nashville's MPE Board issues a master plumber certificate. An out-of-state master plumber has no statewide personal recognition: to contract for $25,000 or more they need the CMC-A or CMC contractor license; to pull small-job permits they need the LLP where it is accepted, or the local master card where it is not.
