Plumber License from California to Louisiana: Does It Transfer? (2026)
Does Louisiana accept a California plumbing license?
There is no California state license to carry to Louisiana: California issues no statewide journeyman plumber license. Louisiana does license this work, so ask the State Plumbing Board of Louisiana (SPBLA) 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 Louisiana to verify or endorse. Louisiana does license plumbers, through the State Plumbing Board of Louisiana (SPBLA), 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. Louisiana waives its journeyman plumber examination only for applicants licensed as journeyman plumbers in Arkansas or Texas under the State Plumbing Board's bilateral reciprocity agreements (license held in good standing and obtained by examination); every other out-of-state plumber must pass the Louisiana written and manual journeyman exam, though a valid out-of-state plumbing license may be submitted to qualify to sit for it.
What's different between California and Louisiana
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Louisiana. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
California to Louisiana (this page): No state license to transfer.
Louisiana 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 Louisiana.
The others get: licensure by endorsement (39) and reciprocity agreement (2).
- Reciprocity agreements
Louisiana's reciprocity agreement list names 2 states (Arkansas and Texas), not including California.
- 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 Louisiana's.
- Exam rules on record
Louisiana and California carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Louisiana (this move): Louisiana waives its journeyman plumber examination only for applicants licensed as journeyman plumbers in Arkansas or Texas under the State Plumbing Board's bilateral reciprocity agreements (license held in good standing and obtained by examination); every other out-of-state plumber must pass the Louisiana written and manual journeyman exam, though a valid out-of-state plumbing license may be submitted to qualify to sit for it
- 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 → Louisiana
| California (current) | Louisiana (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 | $40–$165 (Exam track: $125 examination fee plus $40 initial license fee (about $165 total) per La. Admin. Code tit. 46 Pt. LV §312. Reciprocal Arkansas/Texas applicants are exam-exempt and pay the board's reciprocal application fee (reported around $100 for the Arkansas journeyman-plumber/natural-gas-fitter application), which could not be confirmed on a reachable official page.) |
| Processing time | Not applicable — no state journeyman plumber license is issued | No board-stated processing time published in the LAC or reachable board pages |
| Licensing authority | California Contractors State License Board (CSLB) | State Plumbing Board of Louisiana (SPBLA) |
The destination column is what you must satisfy — Louisiana sets the rules for this move.
Step by step
- Review Louisiana's requirements on the State Plumbing Board of Louisiana (SPBLA) website (linked below) — rules change.
- Ask the State Plumbing Board of Louisiana (SPBLA) whether it credits a local California license or your documented experience: California issues no statewide journeyman plumber license, so there is no state license to verify.
- Otherwise apply as a new applicant: meet Louisiana's education/experience requirements and pass the exams it requires.
- 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 Louisiana?
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 Louisiana license.
