Moving to Wisconsin as a journeyman plumber: every state's rule

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 in the LicensE portal at license.wi.gov with proof of the completed apprenticeship, 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; the plumbing comity statute (Wis. Stat. 145.09) counts out-of-state apprenticeships and licenses toward eligibility for the exam but does not waive it.
