Plumber License from California to Maryland: Does It Transfer? (2026)
Does Maryland accept a California plumbing license?
There is no California state license to carry to Maryland: California issues no statewide journeyman plumber license. Maryland does license this work, so ask the Maryland State Board of Plumbing (Maryland Department of Labor, Division of Occupational and Professional Licensing) 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 Maryland to verify or endorse. Maryland does license plumbers, through the Maryland State Board of Plumbing (Maryland Department of Labor, Division of Occupational and Professional Licensing), 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. Maryland waives its journey plumber examination only for applicants already licensed by examination as a journey plumber/gas fitter in Washington, D.C. (and, at the master level only, in Delaware), plus its own intrastate jurisdictions of Baltimore County and the Washington Suburban Sanitary Commission (WSSC); reciprocity is granted only where that jurisdiction reciprocally waives its exam for Maryland licensees. Every other out-of-state plumber must pass the Maryland journey plumber/gas fitter examination as a new applicant.
What's different between California and Maryland
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Maryland. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
California to Maryland (this page): No state license to transfer.
Maryland 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 Maryland.
The others get: licensure by endorsement (40) and reciprocity agreement (1).
- Reciprocity agreements
Maryland's reciprocity agreement list names 1 state (District of Columbia), 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 Maryland's.
- Exam rules on record
Maryland and California carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Maryland (this move): Maryland waives its journey plumber examination only for applicants already licensed by examination as a journey plumber/gas fitter in Washington, D.C. (and, at the master level only, in Delaware), plus its own intrastate jurisdictions of Baltimore County and the Washington Suburban Sanitary Commission (WSSC); reciprocity is granted only where that jurisdiction reciprocally waives its exam for Maryland licensees. Every other out-of-state plumber must pass the Maryland journey plumber/gas fitter examination as a new applicant.
- 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 → Maryland
| California (current) | Maryland (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 | $43.50 (Journey Plumber/Gas Fitter original license fee is $43.50; the board publishes no separate reciprocity application fee, so reciprocal applicants pay the license fee. No fingerprint/background surcharge is listed.) |
| Processing time | Not applicable — no state journeyman plumber license is issued | ~2 weeks (Board FAQ states a license is mailed within about two weeks of applying; this is stated for original licenses and reciprocal processing time is not separately specified.) |
| Licensing authority | California Contractors State License Board (CSLB) | Maryland State Board of Plumbing (Maryland Department of Labor, Division of Occupational and Professional Licensing) |
The destination column is what you must satisfy — Maryland sets the rules for this move.
Step by step
- Review Maryland's requirements on the Maryland State Board of Plumbing (Maryland Department of Labor, Division of Occupational and Professional Licensing) website (linked below) — rules change.
- Ask the Maryland State Board of Plumbing (Maryland Department of Labor, Division of Occupational and Professional Licensing) 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 Maryland'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 Maryland?
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 Maryland license.
