Plumber License from California to Rhode Island: Does It Transfer? (2026)
Does Rhode Island accept a California plumbing license?
There is no California state license to carry to Rhode Island: California issues no statewide journeyman plumber license. Rhode Island does license this work, so ask the Rhode Island Department of Labor and Training (DLT) — Division of Professional Regulation, State Board of Examiners of Plumbers 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 Rhode Island to verify or endorse. Rhode Island does license plumbers, through the Rhode Island Department of Labor and Training (DLT) — Division of Professional Regulation, State Board of Examiners of Plumbers, 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. Rhode Island waives its journeyperson plumber exam for an applicant duly licensed by examination in another state for the same classification, provided that state's requirements are the same as Rhode Island's; there is no fixed partner-state list, so eligibility is assessed case-by-case and any applicant who does not meet the equivalence test must pass the Rhode Island exam.
What's different between California and Rhode Island
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Rhode Island. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
California to Rhode Island (this page): No state license to transfer.
Rhode Island 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 Rhode Island.
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 Rhode Island's.
- Exam rules on record
Rhode Island and California carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Rhode Island (this move): Rhode Island waives its journeyperson plumber exam for an applicant duly licensed by examination in another state for the same classification, provided that state's requirements are the same as Rhode Island's; there is no fixed partner-state list, so eligibility is assessed case-by-case and any applicant who does not meet the equivalence test must pass the Rhode Island exam
- 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 → Rhode Island
| California (current) | Rhode Island (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 | $72 (Journeyperson plumber license fee $72.00 (plus a $6.00 processing fee) per the RI DLT licensing portal; master plumber is $240.00. A separate initial reciprocity application fee could not be confirmed on an official page because the DLT application PDF was inaccessible.) |
| Processing time | Not applicable — no state journeyman plumber license is issued | No board-stated processing time |
| Licensing authority | California Contractors State License Board (CSLB) | Rhode Island Department of Labor and Training (DLT) — Division of Professional Regulation, State Board of Examiners of Plumbers |
The destination column is what you must satisfy — Rhode Island 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 Rhode Island?
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 Rhode Island license.
