Plumber License from New York to District of Columbia: Does It Transfer? (2026)
Does District of Columbia accept a New York plumbing license?
There is no New York state license to carry to District of Columbia: New York issues no statewide journeyman plumber license. District of Columbia does license this work, so ask the District of Columbia Board of Industrial Trades — Department of Licensing and Consumer Protection (DLCP), 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: New York issues no statewide journeyman plumber license — plumbing there is regulated at the contractor level or by cities and counties — so there is no New York state license for District of Columbia to verify or endorse. District of Columbia does license plumbers, through the District of Columbia Board of Industrial Trades — Department of Licensing and Consumer Protection (DLCP), 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 New York license, a contractor-level credential or your documented hours; otherwise plan to qualify as a new journeyman applicant. The District has no state-to-state plumber reciprocity — the Maryland/Virginia trade reciprocity DLCP publishes applies to electricians, not plumbers. DC waives its journeyman plumber examination only for applicants who prove completion of a nationally-certified apprenticeship program; all other applicants qualify by documenting experience (journeyman: 4 years / 8,000 work hours) and must pass the DC journeyman plumbing exam (open-book on the 2012 International Plumbing Code and 2012 International Fuel Gas Code). The master tier requires 8 years / 16,000 hours and its own exam.
What's different between New York and District of Columbia

- Route, each way
New York to District of Columbia (this page): No state license to transfer.

New York issues no statewide journeyman plumber license, so neither direction is a state-license transfer.

- Fee and processing
New York issues no statewide journeyman plumber license, so there is no New York state license application fee or processing time to compare with District of Columbia's.
- Exam rules on record
District of Columbia and New York carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- District of Columbia (this move): The District has no state-to-state plumber reciprocity — the Maryland/Virginia trade reciprocity DLCP publishes applies to electricians, not plumbers. DC waives its journeyman plumber examination only for applicants who prove completion of a nationally-certified apprenticeship program; all other applicants qualify by documenting experience (journeyman: 4 years / 8,000 work hours) and must pass the DC journeyman plumbing exam (open-book on the 2012 International Plumbing Code and 2012 International Fuel Gas Code). The master tier requires 8 years / 16,000 hours and its own exam
- New York (the reverse move): Not applicable at the state level — New York issues no statewide plumber license, so there is no state journeyman exam to waive or transfer. Each municipality (e.g., New York City) sets and administers its own plumber licensing and exams and generally does not recognize licenses issued by other jurisdictions.
What changes, New York → District of Columbia
| New York (current) | District of Columbia (destination) | |
|---|---|---|
| Application fee | Set locally and varies by municipality; e.g., New York City charges a $585 Master Plumber written-exam fee and a separate $530 practical-exam fee (both paid through DOB NOW; the practical is applied for only after passing the written exam), then a $500 background-investigation fee and a $200 license fee — other cities/counties differ | $175 (Journeyman: $65 application + $110 initial license (up to 2 years) = $175. Master: $65 + $120 = $185. Apprentice license $110. Renewals: journeyman $110, master $155) |
| Processing time | No statewide process; timelines are set by each municipal licensing authority | No board-stated processing time |
| Licensing authority | No New York State plumber licensing board — plumbing is licensed municipally (representative program: New York City Department of Buildings) | District of Columbia Board of Industrial Trades — Department of Licensing and Consumer Protection (DLCP), Occupational and Professional Licensing |
The destination column is what you must satisfy — District of Columbia sets the rules for this move.
