Plumber License from California to Indiana: Does It Transfer? (2026)
Does Indiana accept a California plumbing license?
There is no California state license to carry to Indiana: California issues no statewide journeyman plumber license. Indiana does license this work, so ask the Indiana Professional Licensing Agency (PLA) — Indiana Plumbing Commission 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 Indiana to verify or endorse. Indiana does license plumbers, through the Indiana Professional Licensing Agency (PLA) — Indiana Plumbing Commission, 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. Indiana Code 25-28.5-1-19 (verified current as of 2026-01-01) provides that an out-of-state journeyman plumber 'shall without examination, be granted a license' by the Indiana Plumbing Commission IF the other jurisdiction's licensing requirements were substantially equal to Indiana's when the applicant was last licensed AND that jurisdiction grants Indiana licensees the same reciprocal privilege; the statute names no partner states and no official list of qualifying states was located, so an applicant must confirm eligibility with the Commission, and anyone who does not meet the substantial-equivalence/mutuality test must be approved by the Commission and pass the Indiana journeyman plumber examination.
What's different between California and Indiana
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Indiana. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
California to Indiana (this page): No state license to transfer.
Indiana 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 Indiana.
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 Indiana's.
- Exam rules on record
Indiana and California carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Indiana (this move): Indiana Code 25-28.5-1-19 (verified current as of 2026-01-01) provides that an out-of-state journeyman plumber 'shall without examination, be granted a license' by the Indiana Plumbing Commission IF the other jurisdiction's licensing requirements were substantially equal to Indiana's when the applicant was last licensed AND that jurisdiction grants Indiana licensees the same reciprocal privilege; the statute names no partner states and no official list of qualifying states was located, so an applicant must confirm eligibility with the Commission, and anyone who does not meet the substantial-equivalence/mutuality test must be approved by the Commission and pass the Indiana journeyman plumber examination
- 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 → Indiana
| California (current) | Indiana (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 | $15–$30 (Per 860 IAC 1-1-2.1: journeyman plumber initial license fee is $15 in odd-numbered years or $30 in even-numbered years (biennial cycle; renewal $30 due before Dec 1 of each odd-numbered year). A reciprocity applicant pays the license fee with no exam; a non-reciprocity applicant also pays a $30 Commission examination fee plus the separate exam-vendor (Prove/ICC) fee. All PLA fees are non-refundable) |
| Processing time | Not applicable — no state journeyman plumber license is issued | No board-stated processing time in weeks; a non-reciprocity application must be reviewed and approved for eligibility by the Indiana Plumbing Commission before the applicant may register for the exam. All in.gov hosts refused direct connections during research |
| Licensing authority | California Contractors State License Board (CSLB) | Indiana Professional Licensing Agency (PLA) — Indiana Plumbing Commission |
The destination column is what you must satisfy — Indiana sets the rules for this move.

What happens to my California credential after I'm licensed in Indiana?
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 Indiana license.
