Tennessee to Connecticut: master plumber license reciprocity

Connecticut has no license titled 'master plumber'; the top-tier personal credential is the P-1 Unlimited Plumbing Contractor, issued by DCP to an individual and permitting all plumbing and piping work under CGS 20-330 (permits and contracting with the public). Limited contractor classes cover narrower scopes (J-1, J-3, P-7, P-9, PP-1, SP-1). A new P-1 applicant needs two years as an unlimited licensed journeyperson or equivalent experience and training; the out-of-state equivalency table is 12,000 OJT hours (8,000 plus two years / 4,000) and 576 classroom hours matching Exhibit A. CGS 20-334a(a)(1)(A) lets out-of-state journeyman service count if DCP finds it comparable, and still requires the contractor examination. CGS 20-333a would allow an exam waiver only if the origin state reciprocates, and DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction. Fees are a $150 application fee and a $150 initial/renewal license fee; licenses expire annually on October 31.

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.
