Selling a plumbing company in California

California is the one big plumbing state where an employee can carry the license for you. A C-36 Plumbing license needs a qualifying individual, and a corporation can qualify through a Responsible Managing Officer or Responsible Managing Employee. If that person leaves, the CSLB gives 90 days to replace them. And Chemed's Roto-Rooter bought its largest independent California franchise, covering northern San Diego to Sacramento, for $60.6 million in September 2026.

How many plumbing companies are in California

The 2022 Economic Census counts 11,334 plumbing and HVAC firms combined in California with $1M to $10M in revenue, the most of any state. Census does not split plumbing from HVAC. For you, that number cuts both ways: buyers have plenty of California targets to choose from, so a clean, well documented company stands out, and a messy one gets passed over.

License and qualifier rules when you sell

The CSLB says every license classification, including C-36, needs a qualifying individual who may or may not be the owner. That is the big difference from Texas or New York City. A full time employee who qualifies as the RME can keep the company licensed after you leave, so a licensed employee on your payroll is something a buyer will pay for.

Two cautions from the CSLB's Change in Personnel page. The company has 90 days to replace a departing RMO or RME, with one extension possible, and a sole owner license cannot be sold. If you are a sole owner with the license in your own name, the buyer gets a new license, not yours. Read how buyers price this on our master license page, and confirm the current timing with the CSLB before you sign.

What moves value in California

Recurring work and metro location. Ad Astra describes a residential plumber with 30% or more recurring plans, three masters and a top 50 metro location earning 2 to 3 turns above an owner on the truck shop. If you work in Los Angeles, the Bay Area, San Diego or Sacramento, the question a buyer asks is how much of your work repeats and how many masters you have.

Drain and sewer work is on a large buyer's list here. Chemed told investors on its October 28, 2026 call that it spent $96 million to reacquire Roto-Rooter franchises, primarily in Texas and California.

Buyers active in California

Salt Creek Advisory's tracker (checked November 2026) names two recent California plumbing buyers: Roto-Rooter, owned by Chemed, and ResiXperts, backed by FoW Partners, which bought Handy Plumbing Man in San Carlos in September 2025. Beyond those, expect local competitors and individual buyers using SBA loans, especially for smaller shops. See every buyer type side by side on our plumbing buyers page. We are not paid by any buyer named here.
