CSLB Workers' Comp Exemption Mistakes That Suspend Your License
Updated October 29, 2026
Every California contractor license must show either a current workers' compensation policy or an exemption on file with CSLB. A lapse leads to suspension. In CSLB's own license file, thousands of licenses show a workers' comp suspension pending at any given time.
Mistake 1: claiming the exemption with employees
The exemption is only for businesses with no employees. Hiring anyone, even part time, means you need a policy before they start.
Mistake 2: using it in a classification that cannot be exempt
Roofing (C-39) has required workers' comp for years, and SB 216 added concrete (C-8), HVAC (C-20), asbestos abatement (C-22), and tree service (D-49). Licenses in those classifications must carry a policy even with no employees.
Mistake 3: letting the policy lapse at renewal
When a policy is cancelled or not renewed, the insurer reports it and CSLB moves toward suspension. Renew the policy, or file the exemption if you truly have no employees, before the old one ends.
Mistake 4: forgetting the class codes on renewal
Active licensees with a workers' comp policy certify their three highest-payroll classification codes on the renewal.
What changes in 2028
SB 216 originally required workers' comp for every licensee starting January 1, 2026. SB 1455 moved that date to January 1, 2028, and directed CSLB to set up a process to verify exemption eligibility. Plan now for the cost of a policy if your business relies on the exemption.
