Tennessee to District of Columbia: journeyman plumber license reciprocity

The District of Columbia issues a person-held Journeyman Plumber license (the Board also licenses journeyman gasfitters as a related specialty) through the Board of Industrial Trades in the Department of Licensing and Consumer Protection (DLCP), the same board that licenses electricians and refrigeration mechanics. Under D.C. Code § 47-2853.122 a journeyman plumber must have worked as an apprentice plumber or gasfitter at least 8,000 hours over at least 4 years (a mechanical-engineering degree plus 2 years of practical experience verified by a licensed master, or comparable experience the Board accepts, also qualifies) and then pass the PSI-administered exam, unless the applicant presents a national certifying organization's journeyman plumber certificate that waives both the exam and the subsection (b) experience path. Fees are a $65 application fee and a $110 license fee for a term of up to 2 years; plumber and gasfitter licenses expire March 31 of even-numbered years. The Board publishes a Maryland plumbing reciprocity bulletin; the Reciprocity section of the board page still describes only Maryland and Virginia electricians. No District-law exam applies to journeyman plumbers (§ 47-2853.12(c)(3)).

Tennessee has no statewide journeyman plumber license. The Board for Licensing Contractors licenses plumbing at two other levels only: the Limited Licensed Plumber (LLP), a personal license for projects under $25,000 in municipalities that use the Division of Fire Prevention for permits and inspections (T.C.A. § 62-6-403; photo ID, SSN, Prov LLP trade exam, $75 initial fee; general maintenance under $500 is exempt), and the contractor license with the CMC-A (plumbing) or CMC (full mechanical) classification, a business license required for plumbing work of $25,000 or more. The Board's LLP page tells applicants to check first whether the local government accepts the LLP or runs its own licensing. Journeyman plumber cards therefore exist only where a city or county examines plumbers itself. Metro Nashville's Mechanical, Plumbing, and Electrical Examiners and Appeals Board issues journeyman plumber (and apprentice plumber) certificates; Knoxville registers State Contractors, homeowners, or Unlicensed/State Limited License (LLE or LLP) holders to pull permits and does not publish a separate city journeyman plumber card on that page. An out-of-state journeyman plumber license has no state-level recognition in Tennessee: the Board's trade-exam-waiver form cannot be used for the LLP, and none of the city pages reviewed here publish a reciprocity or exam-waiver path for inbound journeymen.
