How to Sell a Plumbing Business in California (2026)

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

• Anyone can own your shop. California requires no licensed ownership, where New York City requires 51%.
• Sell the shares and the license can stay. The state board lets a corporation keep its license number under new owners.
• California taxes your gain like wages. On a $1 million gain, a single filer owes the state about $103,135.

Is Now a Good Time to Sell?

Yes. Investor-backed groups are buying California plumbing shops, and the owners are keeping a stake.

• Family shops are selling. Modesto’s Tony’s Plumbing took an investment in November 2024, and the founder’s sons kept a minority stake.
• California buyers buy close to home. Burbank’s Repipe Specialists bought a Los Angeles plumbing company in January 2025.
• The work doesn’t wait for the economy. Pipes fail and drains back up in every market. Buyers pay for that.

What Plumbing Businesses Sell For in California

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.

No named source publishes plumbing prices for California alone, so these are national figures. Ask anyone quoting a California-only number where it came from.

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 you’re the only qualifier, buyers price in that risk.

Who Is Allowed to Own Your Shop

Anyone. California’s Contractors State License Board licenses the business itself, and no rule reserves any share of it for a licensed plumber.

What the license needs is a qualifier. Under Business and Professions Code 7068, a company qualifies through an officer or a full-time employee who meets the experience rules.

• Owner or employee. An employee qualifier must work 32 hours a week, or 80% of the hours the business is open, whichever is less.
• A stake only saves a bond. A qualifier who owns less than 10% files a $25,000 qualifier bond. Nothing else turns on ownership.
• Compare New York City. Licensed master plumbers must own 51% there. New Jersey asks for 10%. California, like Texas, asks for none.

One Qualifier, More Than One Company

One qualifier can cover up to three firms a year under section 7068.1. The firms need at least 20% common ownership, a 20% parent link, or mostly the same officers.

The 20% isn’t a stake anyone must hold to own your shop. It matters when you sell one company out of a group. If the common ownership ends, the board says the shared qualifier must come off.

The Day Your Qualifier Leaves

Under section 7068.2, the company notifies the board within 90 days and has 90 days to replace the qualifier. Miss it and the license is suspended automatically.

• One extension, narrowly. Another 90 days only for a disputed date, a death or an agency delay, with a replacement application already filed.
• If the qualifier is you, stay on until your buyer’s replacement is filed. Put that in the purchase agreement.
• A lapse costs more than the license. Under section 7031, a customer of an unlicensed contractor can sue to recover everything they paid.

Sell the Shares and the License Can Stay

No license transfers to another person or company, under section 7075.1. How your deal is built decides whether that matters.

• Share sale of a corporation. The board says the license can be used if the Secretary of State number stays the same. Officers and qualifier can change.
• Merger. A corporation’s license is canceled on merger, under section 7076. Clear the structure with the board first.
• Asset sale. The buyer’s company applies for its own license, posts new bonds and shows workers’ comp cover.
• Sole owner. The license number can’t be sold at all. The new owner gets their own license before contracting.
• LLC. The board treats LLC licenses much like corporate ones, but only names corporations here. Confirm before closing.

How Long a Qualifier Takes

A qualifier needs four years of journey-level experience in the last ten. A buyer without one hires one.

You can qualify your buyer’s new company without retesting. Under section 7065, anyone who qualified a license in the same class within five years skips the exam.

One State License, Every City

Your license comes from the state and works statewide. Cities add business tax and permits, and state law lets them refuse a permit until that tax is paid.

• Los Angeles requires a certificate. Every contractor needs a Business Tax Registration Certificate.
• Share sale: the city accounts stay with the company.
• Asset sale: the buyer’s company registers fresh in every city where it works.

The Tax Clearances Before Closing

California makes the buyer hold back money for two kinds of tax you owe. Each has its own certificate.

1. Sales tax. Under Tax Code 6811, the buyer withholds until you produce a certificate. The tax department says clearance can take 60 days or more.
2. Payroll tax. Either of you requests the Employment Development Department’s release on form DE 2220R. It has 30 days, or the buyer is released.

Only the buyer is protected. The tax department takes what you owe straight out of escrow, which cuts what you receive.

Sales Tax on Your Equipment

California has no exemption for selling a whole business. Under Regulation 1595, equipment sold with a business that needs a seller’s permit is taxed.

Plumbers usually need one. Regulation 1521 makes a contractor the retailer of plumbing fixtures it installs. Agree a written price for the equipment, or the state uses book value.

The Tax on Your Trucks

Vehicles get no exemption either. The buyer pays use tax at the DMV when re-registering each van, under Regulation 1610. Expect a fleet buyer to price that in.

What You Will Owe in Taxes

California taxes a gain as ordinary income, with no lower rate for selling a business. On the 2025 rate schedule, a single filer with a $1 million gain owes the state about $103,135.

• It isn’t a flat 13.3%. The top rates only apply to the slices above each bracket, and the extra 1% starts above $1 million of taxable income.
• Compare Texas and Pennsylvania. Texas takes nothing, and Pennsylvania’s flat 3.07% comes to $30,700.
• Federal tax still applies. 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 federal rate.
• An S corporation pays 1.5% first. California taxes its net income, including the gain on an asset sale, before it reaches you.

Who Buys California Plumbing Businesses

• Redwood Services invested in Tony’s Plumbing of Modesto in November 2024. The founder’s sons run it and kept a significant minority stake.
• Repipe Specialists bought A-1 Total Service Plumbing, a Los Angeles company, in January 2025. Its founder kept a significant stake.
• ResiXperts partnered with Handy Plumbing Man of San Carlos in September 2025.
• Individual buyers borrow. The SBA caps its main program at $5 million.

How to Get Your Shop Ready

• Name the next qualifier. If it’s you, agree who replaces you and when the application goes in.
• Check how your company is set up. A corporation can sell shares and keep its license. A sole owner can’t.
• Get three years of clean books with your personal spending separated out and documented.
• Push service agreements past 30% of revenue. That’s what moves you up a tier.
• Get out of the middle. Build a layer between you and the daily work, and write down how things are done.
• Clear your sales tax and payroll tax accounts before escrow asks for the certificates.

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.

Those numbers hold in California too. See every fee a broker charges, and what selling without a broker takes instead.

Selling a Plumbing Business in Los Angeles

Los Angeles has a California buyer on its doorstep, and one extra registration to move.

• A local buyer, a founder who stayed. Burbank's Repipe Specialists bought A-1, and A-1's founder kept a significant stake.
• Move the city certificate. An asset buyer needs its own Business Tax Registration Certificate before pulling permits.
• The license rules are statewide. No city changes who can own your shop.

Selling a Plumbing Business in Northern California and the Central Valley

Buyers are active well outside Los Angeles, from the Peninsula to the Central Valley.

• Modesto's deal kept the family in. Tony's Plumbing still carries the family name, and the sons kept a minority stake.
• The Peninsula trades too. ResiXperts bought into San Carlos to grow in Northern California.
• The tax is statewide. Where in California you live doesn't change what the state takes from your gain.
