California requirements for hvac & plumbing businesses
California plumbers hold a CSLB C-36 license and HVAC contractors a C-20, each requiring the $25,000 bond and an active workers' compensation filing. Refrigerant work also falls under EPA Section 608. Title 24 energy-compliance documentation on change-outs is a frequent source of disputes with homeowners.
Workers' compensation in California
California requires workers' compensation from the very first employee — there is no small-employer exemption, and officers of a corporation must formally exclude themselves in writing. Rates are developed through WCIRB (California's own rating bureau, not NCCI), and hvac & plumbing payroll typically rates at $3.50 to $10 per $100 of payroll for plumbing and HVAC class codes, with rooftop and new-construction work at the higher end. AB 5 pushes nearly every worker onto a W-2, so payroll you may have treated as 1099 belongs on the comp policy. Miscoded payroll is the single most common reason California employers overpay, and it surfaces at audit rather than at bind.
What California operators actually pay in 2026
The ranges below reflect what KTL clients in California pay today for a small-to-midsize operation, adjusted for California rating. Your actual premium turns on payroll, revenue, loss history, and — more than anything — whether the risk was classified correctly to begin with.
| Coverage | What it covers | Typical CA annual cost |
|---|---|---|
| General Liability | $1M/$2M, service and replacement work | $1,650 – $5,400 |
| Tools & Equipment | Recovery units, cameras, jetters | $650 – $2,250 |
| Commercial Auto | Per service van | $2,150 – $4,500 |
| Installation Floater | Rooftop units and materials on site | $550 – $2,250 |
| Umbrella | $1M–$5M excess | $1,200 – $3,750 |
The California angle most brokers miss
Water-damage claims in California multifamily buildings are the dominant plumbing loss, and many policies restrict damage to the work itself. We confirm the resulting-damage language before binding.
Exposures we underwrite for California accounts
Every submission we send out is built around the specific ways businesses in this class actually have claims. That is what separates a benchmarked program from a rate quote.
- •Water damage from a failed connection in an occupied building
- •Carbon monoxide and combustion-related liability claims
- •Rooftop falls and heavy-equipment rigging injuries
- •Refrigerant handling and EPA 608 compliance issues
- •Callbacks and completed-operations claims on installed systems
