California law requires WC insurance for all contractors with employees. Operating without it can result in fines up to $10,000+ per day.
Employee Protection
WC covers 100% of medical costs for work injuries, plus 66.7% of lost wages. Protects your team and your business.
Business Protection
WC is your only defense against employee lawsuits. Without it, you're personally liable for all injury costs.
Frequently Asked Questions
What is workers' compensation insurance in California?
Workers' compensation (WC) is mandatory insurance in California that covers medical expenses, rehabilitation, and lost wages for employees injured on the job. It's required by law if you have any employees, even part-time.
How much does workers' comp insurance cost for contractors?
WC costs depend on your trade classification, payroll, and claims history. Rates range from $2.50–$12.00 per $100 of payroll. For example, a roofing contractor with 5 employees earning $50,000 each could pay $10,000–$30,000/year.
Do I need workers' comp if I'm a sole proprietor?
Sole proprietors are typically exempt from WC requirements in California, but you can voluntarily purchase coverage. If you hire even one employee, WC becomes mandatory.
What does workers' comp cover?
WC covers medical treatment, hospitalization, surgery, rehabilitation, prosthetics, vocational retraining, and partial wage replacement (66.7% of average weekly wage, capped at state max). It also covers death benefits for dependents if an employee is fatally injured.
Can I lower my workers' comp rates?
Yes. Implement safety programs, maintain a clean claims history, use proper job classifications, and work with a broker who shops multiple carriers. Asena Capital Insurance Services can help you find the lowest rates.
What is a WCIRB class code?
WCIRB (Workers' Compensation Insurance Rating Bureau) class codes categorize jobs by injury risk. Each trade has specific codes (e.g., roofers = 5403). Your code determines your WC rate per $100 of payroll.

Yes. Asena Capital Insurance Services can bind WC policies and issue certificates of insurance within 24 hours, often the same day. Call (858) 925-9555 for immediate coverage.
