Tennessee to Wisconsin: master plumber license reciprocity
Tennessee does not issue a statewide master plumber license, so there is nothing to transfer. Here is Wisconsin's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state master plumber (no reciprocity; exam required, journeyman experience credited toward eligibility)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
DSPS publishes no plumbing reciprocity partners and no exam-waiver route for out-of-state master plumbers, so a master licensed in another state applies through LicensE under Form 3129 like a first-time candidate and must pass the Wisconsin master plumber examination. Wisconsin's master qualification is a period of experience as a licensed journeyman plumber, documented on the Form 3129T experience table; an out-of-state applicant documents that journeyman-level experience and licence history to become eligible to sit the exam. Wisconsin has no separate law or business exam for individual plumbers. Fees are calculated in LicensE.
SPS 305.91 requires at least 1,000 hours of plumbing work per year for 3 years as a licensed journeyman plumber, or an approved engineering degree. Restricted master is a separate DSPS credential. Fee amounts are in SPS 305.02 Table 305.02 (PDF), not on the DSPS plumber pages: https://dsps.wi.gov/Pages/Professions/MasterPlumber/Default.aspx

How Wisconsin licenses master plumbers
Wisconsin master plumber · “Master Plumber”
Statewide license
Issued by Wisconsin Department of Safety and Professional Services (DSPS)
Wisconsin issues a statewide, person-held Master Plumber license through DSPS under Wis. Stat. ch. 145; no person may work at plumbing without a DSPS license (Wis. Stat. 145.06), and under SPS 305.91 a master plumber responsible for an installation must use appropriately credentialed persons to do the work. A new applicant files Form 3129 (with the Form 3129T experience table) in the LicensE portal, is made eligible to test, and must pass the DSPS master plumber examination, an open-book exam on Wis. Stat. ch. 145, SPS 305 and the SPS 381-387 plumbing code (the updated code applies to exams from October 1, 2026). DSPS's plumber pages name no reciprocity states.
Why Tennessee has nothing to transfer
Tennessee master plumber · “Master plumber (city or county card); state CMC-A plumbing contractor is a business license”
Licensed by cities and counties
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.
How local licensing works in Tennessee
State contractor route (CMC-A / CMC) — business license, not a personal master. Required statewide to bid or contract plumbing of $25,000 or more (subcontractor plumbing portion counted with materials, equipment and labor). Qualifying agent (owner, officer or full-time employee) takes the Tennessee Business and Law exam and the CMC-A or CMC trade exam after a $50 pre-approval request to [email protected]. Up to two people may take each exam; Business and Law and the trade exam need not be the same person. Application $250 at core.tn.gov. From 2026-07-01 a contractors' surety bond of at least 50% of the requested monetary limit may replace a CPA-reviewed or audited financial statement. General liability and workers' compensation (or exemption) are required on the contractor application. Trade exam waiver (not Reciprocity for a master plumber card): origin board completes the Request for Contractor License Verification in lieu of the Tennessee trade exam score. Plumbing rows: Ohio Plumbing -> CMC-A; South Carolina Plumbing -> CMC-A; Louisiana Mechanical -> CMC; Mississippi Mechanical -> CMC; West Virginia Mechanical -> CMC. Business and Law is never waived. Ineligible if discipline, open complaints or felony convictions. Cannot be used for LLP, LLE or home improvement. NASCLA accredited exams on the Board exam page are commercial building and electrical, not plumbing.
State LLP (personal, limited, not master). $75 initial, Prov LLP exam, under $25,000, Fire Prevention jurisdictions only, no exam waiver. A Tennessee CMC-A/CMC firm may still need Metro registration to pull permits; confirm with Codes (615-862-6500).
Knoxville. State Contractor registration (CMC-A/CMC) or Unlicensed/State Limited License (LLP) registration to pull permits.

- Knoxville (Plans Review & Inspections)
- Chattanooga (Land Development Office)
- Memphis / Shelby County (Office of Construction Code Enforcement)
