C-15 flooring licenses in California: who is insured today
CSLB lists 6,317 active C-15 licenses (CSLB license file, September 2026). 51% show a workers' comp policy on file, and 48% (3,003) have filed a workers' comp exemption, which means no employees. 51% are sole owners. The most licenses are in Los Angeles (1,106), San Diego (672), Orange (582).
If your license is one of the exempt ones, the rule changes on January 1, 2028: SB 216, as delayed by SB 1455, requires every active California contractor license to carry workers' comp, except joint ventures with no employees. A one-person shop will need a policy to keep the license active, even with no employees. Ask us early so the policy is in place before CSLB checks it.
| CSLB workers' comp status | Licenses | Share |

| Workers' comp policy on file | 3,197 | 51% |
| Exempt (no employees) | 3,003 | 48% |
