Plumber License from California to Wisconsin: Does It Transfer? (2026)
Does Wisconsin accept a California plumbing license?
There is no California state license to carry to Wisconsin: California issues no statewide journeyman plumber license. Wisconsin does license this work, so ask the Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing whether it credits a local license or your documented experience; otherwise you qualify as a new applicant.

Verdict
No state license to transfer
The issue on this move is the starting point: California issues no statewide journeyman plumber license — plumbing there is regulated at the contractor level or by cities and counties — so there is no California state license for Wisconsin to verify or endorse. Wisconsin does license plumbers, through the Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing, and it reviews out-of-state plumbers for endorsement, but that route starts from a state license. Ask the board, in writing, whether it credits a local California license, a contractor-level credential or your documented hours; otherwise plan to qualify as a new journeyman applicant. 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.
What's different between California and Wisconsin
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Wisconsin. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
California to Wisconsin (this page): No state license to transfer.
Wisconsin to California (the reverse move): No state license to transfer.
California issues no statewide journeyman plumber license, so neither direction is a state-license transfer.
- Does coming from California matter?
Coming from California matters here: only 9 of 50 origins (the other 49 states and DC) get this result for a move into Wisconsin.
The others get: licensure by endorsement (41).
- Fee and processing
California issues no statewide journeyman plumber license, so there is no California state license application fee or processing time to compare with Wisconsin's.
- Exam rules on record
Wisconsin and California carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Wisconsin (this move): 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
- California (the reverse move): Not applicable at the journeyman level — California issues no state journeyman plumber license, so there is no state journeyman trade exam. Plumbing is licensed only at the contractor level by the Contractors State License Board (C-36 Plumbing). At that contractor tier, CSLB has a reciprocity agreement covering the C-36 classification with Arizona only: an Arizona C-37 or C-37R contractor who has held that license active and in good standing for the previous five years may have the C-36 trade exam waived (CSLB reserves the right to require it), but must still pass CSLB's Law and Business exam. CSLB's other reciprocity partners (Nevada, Louisiana, Mississippi, North Carolina) do not map to C-36 Plumbing.
What changes, California → Wisconsin
| California (current) | Wisconsin (destination) | |
|---|---|---|
| Application fee | No state journeyman plumber license exists, so there is no journeyman fee. For reference, the CSLB C-36 plumbing CONTRACTOR license (contractor tier, out of scope) is $450 original application + $200 initial license fee (sole owner) / $350 (non-sole owner), plus a bond and Live Scan fingerprint fee | $180 ($180 journeyman plumber credential fee (4-year term) per the DSPS Trades fee schedule; a nonrefundable application fee and a journeyman examination fee are also collected and are calculated within LicensE (not itemized on the fee schedule). Master plumber term fee is $500) |
| Processing time | Not applicable — no state journeyman plumber license is issued | DSPS does not publish a fixed processing time; the applicant is made exam-eligible after DSPS reviews the submitted application and documents |
| Licensing authority | California Contractors State License Board (CSLB) | Wisconsin Department of Safety and Professional Services (DSPS) — Division of Professional Credentialing |
The destination column is what you must satisfy — Wisconsin sets the rules for this move.

- Submit the application with fees listed above, and allow for the processing time shown there.

Frequently asked questions
What happens to my California credential after I'm licensed in Wisconsin?
Nothing changes it. California issues no statewide journeyman plumber license, so any local or contractor-level California credential you hold runs on its own authority's renewal rules, independently of your Wisconsin license.
