Plumber License from California to Wisconsin: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing ↗
A plumbing license transfers from California to Wisconsin by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing, verify your California license, and meet Wisconsin's endorsement requirements. Wisconsin does NOT waive its journeyman plumber examination for any out-of-state applicant and has no reciprocity agreements; every applicant must pass the Wisconsin journeyman plumber exam. Out-of-state plumbers qualify to sit that exam by 'comity' — documenting an out-of-state 5-year apprenticeship (minimum 576 hours of related instruction), or having passed a journeyman exam in another state and practiced at least 5 years under a license the Department finds substantially similar to Wis. Stat. ch. 145 — so no fresh Wisconsin apprenticeship is required, but the Wisconsin exam is mandatory.

Licensure by endorsement
California is not among the states Wisconsin names for an automatic exam waiver, so this move runs on the Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing's individual endorsement or equivalency review rather than a guarantee. Wisconsin does NOT waive its journeyman plumber examination for any out-of-state applicant and has no reciprocity agreements; every applicant must pass the Wisconsin journeyman plumber exam. Out-of-state plumbers qualify to sit that exam by 'comity' — documenting an out-of-state 5-year apprenticeship (minimum 576 hours of related instruction), or having passed a journeyman exam in another state and practiced at least 5 years under a license the Department finds substantially similar to Wis. Stat. ch. 145 — so no fresh Wisconsin apprenticeship is required, but the Wisconsin exam is mandatory. Bring your California license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
