Tennessee to Utah: master plumber license reciprocity

Utah issues a statewide Master Plumber license through DOPL under Utah Code 58-55 and Rule R156-55c, alongside a Residential Master Plumber license limited to residential work. A new master needs 4,000 hours of licensed journeyman plumber experience as a supervisor (or an associate of applied science or similar CHEA-recognized degree plus 2,000 supervisory hours) and must pass the Prov-administered Utah Master Plumber Law and Rule Examination with at least 75%; the DOPL application fee is $116. Utah has no master-level reciprocity agreements. Out-of-state masters whose license is green on DOPL's Endorsement to Utah: Master Plumber map apply by endorsement under Utah Code 58-1-302 after holding the license at least one year, active and in good standing, but 'All applicants will be required to pass the Utah Master Plumber Law and Rule exam.' Several states issue only a plumbing contractor license (light blue on the map); DOPL may endorse the individual who qualified as that contractor's responsible person. Applicants without an equivalent license use verified out-of-state journeyman supervisory hours toward the standard route. Renewal requires 12 hours of approved CE per licensing cycle.

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.
