If you’re planning to work as a plumber—or even do minor plumbing work—in New York, you’ve probably asked yourself: “Does the state of New York require a plumbing license?” It’s a smart question. Working without proper credentials can result in fines, legal trouble, or even voided insurance claims. In this guide, we’ll clear up the confusion and give you the exact steps you need to stay compliant in 2026.
Does New York State Require a Plumbing License?
Short answer: No—but your city or county almost certainly does.
Unlike many states, New York does not issue a statewide plumbing license. Instead, plumbing licensing is handled at the local level—primarily by New York City, but also by counties like Suffolk, Nassau, Westchester, and others.
This means two plumbers doing identical work in different parts of New York may face completely different rules. That’s why understanding your specific jurisdiction is critical.
💡 Pro Tip: Always check with your local building department before starting any plumbing project—even if it’s just replacing a faucet.

What About Other Parts of New York State?
Outside NYC, licensing varies:
| Location | License Required? | Governing Body | Notes |
|---|---|---|---|
| Long Island (Suffolk/Nassau) | ✅ Yes | County Building Departments | Journeyman & Master licenses required |
| Westchester County | ✅ Yes (in most towns) | Local municipalities | Yonkers, White Plains require exams |

Common Misconceptions About Plumbing Licenses in NY
Let’s clear up three big myths:
- “If it’s not state-regulated, I don’t need a license.”
→ False. Local laws still apply—and local inspectors have full enforcement power. - “I can get a ‘state plumbing certificate’ online.”
→ Scam alert. New York does not offer a state plumbing license. Any website selling one is not legitimate. - “Handyman work doesn’t count as plumbing.”
→ Not true. Installing a water heater, sewer line, or even a new sink often requires licensed plumbing oversight in most NY jurisdictions.
