There is no New York State plumbing license to get: New York licenses plumbers locally, and in Westchester County the license comes from the county itself.
Plumbers must obtain a trade license from Westchester County to work in the county, and the county's stated first step is to apply to take the licensing examination.
Here is what our research verified about the Westchester County plumbing license — and what to confirm with the county.
County vs. state licensing in New York
New York issues no statewide plumber license.
Plumbing licenses are issued locally, and state law frames it that way: General City Law Article 4, "Plumbing and Drainage," §40-a provides for examining boards of plumbers in cities.
The practical upshot: the license you hold comes from the city or county where you work, not from a state office.
In Westchester County, the issuer is the county.
Plumbers and electricians "must obtain a trade license from Westchester County in order to work in the county," and the county licenses them county-wide through its Department of Consumer Protection.
The plumbing license is earned by examination — the county's own licensing page makes applying for the licensing exam the first step — and the county maintains a Plumbing Board for the trade.
New York City runs its own local system for the trade, licensing plumbers through its Department of Buildings.
That regime is a different question from Westchester's county license, and our New York plumbing license guide owns it.
For the national picture — the apprentice, journeyman and master rungs, and how the states differ — our plumbing license requirements guide explains the ladder.
Westchester County plumbing license requirements and exam
The framework our research verified is straightforward: Westchester County requires plumbers to hold a county trade license obtained by examination.
The county's own page tells applicants that the first step is to apply to take the licensing examination, and the county maintains a Plumbing Board for the trade.
The county also publishes a list of plumbing continuing-education course providers; what continuing education it currently requires of license holders is a detail to confirm with the county.
Beyond that framework, our research pass did not capture the specifics you will actually file: the application fee, the exam's content or testing vendor, the experience or eligibility documentation the county expects, or the renewal cycle.
Those are not details to guess at.
Start from the county's plumbers-and-electricians page on consumer.westchestergov.com and confirm each one with the county.
- Confirm the current application, exam and license fees with the county
- Ask for the exam schedule, its content outline and any eligibility paperwork
- Ask what experience documentation the county wants with the application
- Confirm the renewal cycle and any continuing education the county requires
If you run a plumbing business rather than work as a plumber, note the county's second layer: "Westchester law requires that home improvement contractors have a county license," per the county's home improvement contractors page.
Whether your business needs that license alongside the plumbing trade license is a question to put to the Department of Consumer Protection before you take on work.

How to look up a Westchester County plumbing license
Westchester County keeps its own Trade Licenses Search for the licenses it issues, reached from the county's consumer-protection site at consumer.westchestergov.com.
If you are hiring a plumber, that is where to look up a county trade license; if you hold one, it is where to look up your own.
Our research notes the search by name rather than a direct address, so start from the county site and follow its trade-license links.
New York has no statewide plumbing license, so a license issued somewhere else sits with whoever issued it.
New York City licenses check through the Department of Buildings' Check License Status service — our NYC master plumber license guide covers that license — and beyond these two, our research did not verify who licenses plumbers, so start from the city, town or county where the work will happen.
For the official lookup portals in the other states, our plumbing license lookup directory walks through them.
Career information, not legal advice. Licensing requirements change; confirm current Westchester County plumbing licensing requirements with the county Department of Consumer Protection before you apply for or rely on a license.
