Plumber Insurance in California
California requires Workers' Compensation for plumbers. See the checklist below for the full breakdown and costs.
California handles plumber insurance through the private market, with workers' comp mandatory the moment you take on staff.
The detail that sets California apart for anyone handling other people's animals is liability: the state follows a strict liability standard when a dog bites, which is exactly why the coverage priorities below look a little different here than they would a state over.
How California regulates plumbers
Workers' comp · Private market
California requires workers' compensation for any business with one or more employees (Labor Code § 3700), and enforcement is strict — operating uninsured is a criminal misdemeanor with heavy penalties. Solo pet sitters and walkers with no staff are exempt until they hire, at which point comp is mandatory from the very first employee.
Statutory disability · State Disability Insurance (SDI) + Paid Family Leave
California mandates State Disability Insurance and Paid Family Leave, funded by employee payroll deductions the employer withholds and remits to the EDD. It's a payroll/administrative obligation once you run payroll — not, by default, a policy you purchase from an insurer (though the state does let employers substitute an approved Voluntary Plan).
Dog-bite liability · Strict liability (statutory)
Cal. Civ. Code § 3342California is a strict-liability state: a dog's owner is liable for bite injuries in a public place, or when the victim is lawfully on private property, even absent any prior history. While the statute names the owner, a pet-care business in control of the animal still faces clear negligence exposure — and California juries award generously — so higher general-liability limits are worth carrying here.
Licensing & permits
California has no statewide sitter/walker license, but a local business license is nearly universal, and some cities and parks cap how many dogs one walker may handle at once — San Francisco allows up to eight, with lower limits in some counties and open-space districts. Commercial kennels and boarding facilities need local permits, and breeders who sell animals face additional local and state rules.

Plumber insurance in California — FAQ
Do plumbers need workers' comp in California?+
Yes — California requires workers' comp from your first employee. Solo plumbers with no staff are generally exempt until they hire.
If a dog in my care bites someone in California, am I liable?+
California is a strict-liability state: a dog's owner is liable for bite injuries in a public place, or when the victim is lawfully on private property, even absent any prior history. While the statute names the owner, a pet-care business in control of the animal still faces clear negligence exposure — and California juries award generously — so higher general-liability limits are worth carrying here. That's why general-liability and animal-bailee coverage are worth prioritizing for plumbers working in California.
Do plumbers need insurance?+
Yes. Plumbers face frequent water-damage and property claims. General liability, workers' comp, and commercial auto are the core policies, and most plumbing licenses require proof of liability coverage.
How much is general liability for a plumber?+
Typically $400–$850 per year for a small operation. Larger crews, commercial work, and gas-line work push premiums higher.
Is workers' comp required for plumbers?+
Yes in nearly every state once you have employees. Even solo plumbers often carry it because lifting and slip injuries are common. Texas is the only state where it's optional.
Does general liability cover water damage I cause?+
Yes — if you accidentally cause water damage to a customer's property during a job, general liability covers the resulting claim. It does not cover damage to your own property or workmanship guarantees.
