What changes on January 1, 2028
SB 216 (2021) originally required every active CSLB license to carry workers' compensation starting January 1, 2026, whether or not the contractor has employees. SB 1455 (2024) moved that date to January 1, 2028. After that date, the no-employee exemption ends for all classifications; joint-venture licenses are the only exception. C-8 concrete, C-20 HVAC, C-22 asbestos abatement, C-39 roofing and C-61/D-49 tree service contractors already cannot file the exemption.A license without required workers' comp on file is suspended, and a suspended license cannot legally contract.

What a currently-exempt contractor should do
Confirm your license's current workers' comp status on CSLB's Instant License Check.
If you have no employees, ask about a workers' comp policy for owners with no payroll — pricing depends on classification and carrier.
Line up the policy before your renewal or before January 1, 2028, so CSLB receives the certificate in time.
If you hire anyone before then, your exemption is no longer valid — you need a policy immediately.
Methodology
Asena Capital Insurance Services analyzed CSLB's public Master License file (downloaded from the CSLB Public Data Portal; last update 2026-09-24). We counted licenses with an expiration date on or after that date and a California address — 226,463 licenses. Workers' comp status is CSLB's recorded coverage type for each license ('Exempt', 'Workers' Compensation Insurance', leasing firm, self-insured, or no current coverage). Classification counts include every license holding that class, so a multi-class license is counted in each of its classes. County is the county of the license's business address. Figures will change as CSLB updates its file.

Frequently asked questions
How many California contractors need workers' comp by 2028?
113,190 active licenses were on file as exempt as of 2026-09-24; each will need a policy by January 1, 2028 unless it is a joint-venture license.
Can a California contractor with no employees still be exempt from workers' comp?
Until January 1, 2028, yes — except C-8, C-20, C-22, C-39 and C-61/D-49 licenses, and licenses qualified by an RME. From January 1, 2028, only joint-venture licenses can be exempt.
What happens if a contractor doesn't have workers' comp on file?
CSLB suspends the license, and contracting on a suspended license is illegal.
