Selling a plumbing company in New York

If you work in New York City, the master plumber license is tied into who owns and runs your company. The NYC Department of Buildings says an applicant must be an officer, partner or sole proprietor of the business, and the business must have a place of business in the city. New York also has 7,089 plumbing and HVAC firms combined in the $1M to $10M band, and EPA now requires all lead service lines replaced within 10 years or less.

How many plumbing companies are in New York

The 2022 Economic Census counts 7,089 plumbing and HVAC firms combined in New York with $1M to $10M in revenue; Census does not separate the two trades. That is the fourth most among our launch states. With that many shops to compare, buyers can be picky about license structure, so yours needs to be clear before you start talking.

License and qualifier rules when you sell

In New York City, the DOB's master plumber license page says the applicant must be an officer, partner or sole proprietor of the business, and the business must have a place of business in New York City. That is one of the strictest setups in the country, because the licensee is part of the ownership or officer structure, not just an employee.

What it means in a sale: a buyer cannot simply hire a master and keep going. Someone licensed has to sit in the officer or partner seat of the business that holds the license. Expect a longer seller transition if you are that person, and expect buyers to want retention packages for any licensed employee who could step in. Our master license page covers the plans that work.

Outside the city, plumbing licensing in New York is local, and we have not checked each county or town. Ask your local building department and an attorney what follows the company and what follows you.

What moves value in New York

Lead lines are a long tail of work. EPA's final Lead and Copper Rule Improvements require drinking water systems to replace all lead service lines within 10 years or less. In our view, lead lines are concentrated in older Northeast cities, so a New York shop with excavation or trenchless capability has a story to tell a buyer.

Union labor narrows the field. In our view, union commercial shops in New York mostly sell to mechanical contractors or through an ESOP, because residential platforms rarely buy union shops.

Buyers active in New York

Salt Creek's 2026 list of plumbing deals, checked November 2026, names no New York deals. That does not mean no one is buying. Sila Services describes its footprint as the Northeast, Mid-Atlantic and Midwest. For most New York shops the likely buyers are a nearby competitor, a key employee who already holds the license, or an individual buyer with a licensed partner. See how each buyer type works on our plumbing buyers page. No buyer mentioned here pays us.
