Tennessee to Wisconsin: journeyman plumber license reciprocity

Wisconsin issues a statewide Journeyman Plumber license through the Department of Safety and Professional Services (DSPS); under Wis. Stat. 145.06 no person may engage in or work at plumbing in the state unless licensed by DSPS, and there is no municipal plumber licensing. Under SPS 305.93 a journeyman works under the general supervision of a Master Plumber, Master Plumber Restricted or Utility Contractor licensee, qualifies by completing a plumbing apprenticeship under Wis. Stat. ch. 106, and must complete 24 hours of approved continuing education to renew. A new applicant files Form 3126 (with the Form 3126T experience table) in the LicensE portal at license.wi.gov, is made eligible to test, and must pass the DSPS journeyman plumber examination, which is a two-part, open-book exam with a 70% passing score covering Wis. Stat. ch. 145, SPS 305, the SPS 381-387 plumbing code, NFPA 13D/24 and the POWTS component manuals (the updated plumbing code applies to exams from October 1, 2026). DSPS's plumber pages name no reciprocity states, and the electrical reciprocity statute (Wis. Stat. 101.874) does not extend to plumbers.

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.
