How to Sell a Plumbing Business in New York (2026)

Owner-run plumbing shops in New York sell for 2 to 4 times what the business pays the owner each year. Bigger companies sell for 5 to 11 times profit.

• In New York City, licensed plumbers have to own most of your company. The rule is 51%, so a buyer without a license cannot take the majority.
• There is no grace period. The day you step out, the company can lose its right to do plumbing work.
• New York taxes the sale like a paycheck. About 6.85%, and the city adds 3.876% on top of that.

Is Now a Good Time to Sell?

Yes, if your ownership question is answered. The investor-backed groups rolling up HVAC want plumbing too, often in one deal.

• The work does not wait for the economy. Pipes fail and drains back up in every market. Buyers pay for that.
• New York has old pipe. Prewar buildings, brownstones and aging supply lines keep repipe and sewer work coming.
• The risk is waiting. The licensing problem below takes years to solve, not months.

What Plumbing Businesses Sell For in New York

Under about $500K a year to you, buyers multiply what the business pays you. Above that, they multiply profit with a manager’s pay taken out.

Run your own shop’s numbers and value a plumbing business.

What Moves Your Number

• Repeat revenue. Get 30% of your work under service agreements and you clear 6 times. All-transactional shops sit lower.
• Commercial mix. Worth roughly one to one and a half turns over residential-only work. The contracts are bigger.
• Whether the shop needs you. If you hold the relationships and the only license, buyers price in that risk.

The 51% Rule, and Why It Decides Who Can Buy You

This is the most important part of this page, and it has no equal in Pennsylvania or New Jersey.

The rule lives in section 28-408.6 of the New York City Administrative Code. Licensed master plumbers must own “no less than 51 percent of the control and voting capital stock” of the company.

• An investor group cannot take the majority. Not unless it brings its own licensed master plumber to hold the stock.
• Your buyer pool narrows before price is even discussed. The most likely buyer is another licensed plumber.
• New Jersey asks for 10% and Pennsylvania handles it locally. New York City is far tighter than both.

There Is No Grace Period

Section 28-408.6.3 is the sentence that should change how you plan your exit. If the licensed master plumber withdraws, the company’s right to do plumbing work lapses.

Not after a warning. Not after a transition window. New Jersey gives an electrical business at least six months when its qualifier dies. New York City gives you nothing.

So your buyer’s licensed plumber has to be in place at closing, not after it.

One Plumber Can Only Cover Two Companies

A master plumber whose stake makes up part of that 51% may hold a qualifying interest in only one other business. Two companies total, and no more.

That is a real ceiling on anyone buying up city shops. A group needs a fresh licensed partner for every third company it takes on.

The Exception Worth Checking

A business doing plumbing work before 25 January 1990 can be exempt from the 51% rule. It had to apply to the department by July 1990 and prove it employed ten or more journeymen.

If that is your company, an investor-backed buyer can own it outright when the shop down the road cannot be bought that way. Confirm your own status with the department before you rely on it.

The Fix, and It Takes Years

A New York City master plumber needs seven years of experience in the ten years before applying, two of them as a registered journeyman.

• You cannot create a successor quickly. Compare that to five years for a New Jersey electrical qualifier.
• Applications moved online in February 2026. Everything now runs through DOB NOW: Licensing.
• Outside the city, check locally. New York City sets this rule, and other places handle licensing their own way.

The Tax Form Your Buyer Has to File

New York makes the buyer handle the back-tax paperwork, the same way New Jersey does. Pennsylvania puts it on the seller.

Here is how New York’s bulk sale notification works.

1. The buyer files Form AU-196.10 at least 10 days before paying you or taking over, whichever comes first.
2. Within 5 business days the Tax Department says whether it has a claim against you.
3. If it does, the buyer puts the full purchase price into escrow.
4. The state then has up to 90 days to report what you owe.

Read step three again. New Jersey escrows the tax at issue. New York escrows everything, so one open sales tax matter can freeze your entire price for three months.

Buyers always file, because skipping it makes them liable for your unpaid sales tax. Clear any exposure a year out, not at closing.

What You Will Owe in Taxes

New York gives you no break for selling a business you spent thirty years building. The gain is taxed on the ordinary income schedule, like wages.

Most sellers land at 6.85%. New York City residents add another 3.876% on top, for about 10.7% in total.

• Compare that to Pennsylvania’s flat 3.07%. On a $1 million gain it is roughly $107,000 in the city against $30,700, a gap near $76,000.
• Ignore the 10.9% headline. That bracket starts above $25 million and applies to almost nobody.
• Federal tax comes on top. Expect 15% to 20% on the gain, plus a 3.8% investment income tax.
• Your trucks are different. Anything you already wrote off is taxed again at your regular rate.

Who Buys New York Plumbing Businesses

• New York buyers are already doing New York deals. Northwinds Services Group, based in Rochester, bought Phoenix Mechanical of Westchester and Putnam in January 2026.
• The national platforms work here too. Apex Service Partners, Wrench Group and Sila Services buy plumbing alongside HVAC.
• In the city, every one of them needs a licensed partner. Ask any buyer who that person is before you go far.
• Individual buyers borrow. The SBA caps its main program at $5 million, and lenders want the license question settled first.

For the tradeoffs, see investor-backed versus strategic buyers for plumbing sellers.

An investor group’s offer arrives in parts. What gets held back, and the stake you keep.

How Long It Takes

How to Get Your Shop Ready

• Answer the ownership question first. Know who will hold the 51%, and get it in writing before you go to market.
• Check whether you are grandfathered. A pre-1990 exemption widens your buyer pool enormously.
• Get three years of clean books with your personal spending separated out and documented.
• Push service agreements past 30% of revenue. That is what moves you up a tier.
• Add commercial work to capture the premium over a residential-only book.
• Get out of the middle. Build a layer between you and the daily work, and write down how things are done.
• Clear any sales tax exposure before your buyer files, so your whole price does not sit in escrow.

Should You Use a Broker, a Marketplace, or Sell Direct?

A buyer who knows you have no alternative has no reason to open with their best number.

Selling a Plumbing Business in New York City

The five boroughs are the densest plumbing market in the country, and the hardest one to sell in.

• The 51% rule shapes every conversation. Buyers arrive knowing it, and the ones who do not are wasting your time.
• The work is excellent. Prewar buildings, high-rise residential and constant repipe jobs push your average ticket up.
• City tax stacks on the state rate. A city resident pays roughly 10.7% before federal tax.

Selling a Plumbing Business Outside the City

Long Island, Westchester, the Hudson Valley and upstate all run on different local rules, so check your own municipality.

• Your buyer pool is usually wider. Without the city's ownership rule, an investor group can buy you outright.
• The 3.876% city tax does not apply if you do not live in the city, which is worth real money on a large deal.
• Buyers are active here. The Westchester deal above is one example, and Long Island shops draw the same interest.
