Plumber License from California to Connecticut: Does It Transfer? (2026)
Does Connecticut accept a California plumbing license?
There is no California state license to carry to Connecticut: California issues no statewide journeyman plumber license. Connecticut does license this work, so ask the Connecticut Department of Consumer Protection — Plumbing and Piping Work Examining Board 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 Connecticut to verify or endorse. Connecticut does license plumbers, through the Connecticut Department of Consumer Protection — Plumbing and Piping Work Examining Board, 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. Connecticut has no reciprocity agreements and does not waive its plumbing examination; every applicant, including one qualifying through an equivalent out-of-state license, must pass the Connecticut P-2 journeyperson examination. An equivalent out-of-state license only substitutes for a Connecticut-registered apprenticeship in meeting the 576 classroom-hour + 8,000 on-the-job-training-hour requirement.
What's different between California and Connecticut
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Connecticut. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
California to Connecticut (this page): No state license to transfer.
Connecticut 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 Connecticut.
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 Connecticut's.
- Exam rules on record
Connecticut and California carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Connecticut (this move): Connecticut has no reciprocity agreements and does not waive its plumbing examination; every applicant, including one qualifying through an equivalent out-of-state license, must pass the Connecticut P-2 journeyperson examination. An equivalent out-of-state license only substitutes for a Connecticut-registered apprenticeship in meeting the 576 classroom-hour + 8,000 on-the-job-training-hour requirement
- 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 → Connecticut
| California (current) | Connecticut (destination) | |
|---|---|---|
| Training hours | — | 576 |
| 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 | $90 ($90 non-refundable journeyperson application fee; license renews annually (all plumbing/pipefitting licenses expire October 31) with a $120 journeyperson renewal fee; a separate examination fee is paid to the exam vendor at registration. The contractor (P-1) application fee is $150) |
| Processing time | Not applicable — no state journeyman plumber license is issued | No board-stated processing time |
| Licensing authority | California Contractors State License Board (CSLB) | Connecticut Department of Consumer Protection — Plumbing and Piping Work Examining Board |
The destination column is what you must satisfy — Connecticut sets the rules for this move.

What happens to my California credential after I'm licensed in Connecticut?
