Coverage for California contractors (License #6002332)
License requirements for C-20 contractors
- License bond: CSLB requires a $25,000 contractor license bond for every active license.
- Workers' compensation: CSLB lists C-20 among the classes that must carry workers' compensation even with no employees. (Refrigeration-only work is a separate class, C-38.)
- LLC licensees: CSLB also requires liability insurance of at least $1 million aggregate (more with a larger personnel of record) and a $100,000 LLC employee/worker bond.
- 2028 change: starting January 1, 2028, CSLB will require workers' compensation for all active licensees, even without employees (SB 216, as delayed by SB 1455).
Key risks
- Fire, gas or carbon-monoxide claims tied to an installed system
- Water damage from condensate lines and leaks
- Injuries on rooftops, in attics and in crawl spaces
- Service vans and tools on the road every day
- Refrigerant handling and environmental exposures
Coverages to discuss
- General liability — third-party injury and property damage, including completed operations. Contracts often specify limits and additional-insured endorsements.
- Workers' compensation — medical care and lost wages for injured employees; required for this class even without employees.
- Commercial auto — trucks, vans and trailers used for the business.
- Inland marine / tools & equipment — gear on the jobsite and in transit.
- Umbrella / excess — added limits when a contract requires more than your GL policy.
- Surety bonds — license bond and, where needed, bid, performance and payment bonds.
Certificates of insurance
Most general contractors and owners ask for a certificate of insurance (COI) and sometimes additional-insured or waiver-of-subrogation endorsements. Request one through /coi-request.
FAQ
Does an HVAC contractor in California need workers' comp?
Yes. CSLB requires active C-20 licensees to carry workers' compensation even if they have no employees.
Do I need general liability insurance for a California contractor license?
CSLB does not require general liability for every license, but it does require it for LLC licensees (see below), and most project owners, general contractors and property managers will ask for a certificate of insurance before you start work.
What does an LLC licensee have to carry?
CSLB requires LLC licensees to carry liability insurance of at least $1 million aggregate, with higher minimums for larger personnel of record, plus a $100,000 LLC employee/worker bond. See our guide at /insights/cslb-llc-insurance-worker-bond.
Will workers' comp rules change in 2028?
Yes. Under current law (SB 216, as delayed by SB 1455), every active CSLB licensee must have workers' compensation on file starting January 1, 2028, even with no employees. CSLB has proposed an exemption-verification process that would need new legislation, so check cslb.ca.gov for updates. See /insights/cslb-workers-comp-requirement-2028.
