Contractor Labor Cost in California

Workers’ compensation and payroll basics that change a California contractor’s true hourly labor cost, with official starting points.

California requires workers’ compensation for employees

In California, workers’ compensation is mandatory for employers with employees. Because premiums depend on classification, payroll, and your insurer, the cost added to each labor hour varies by business—so a statewide average is not a safe estimate.

What changes labor cost in California

  • Workers’ compensation classification and policy rate.
  • State unemployment (SUTA) rate assigned to the employer.
  • State and local minimum wage and overtime rules.
  • Paid sick leave and other state-mandated benefits.
