What this means

The licence is active: CSLB lists its status as clear. That means no suspension is on file; it does not rate the quality of the work.
Contractor's bond: $25,000 with Business Alliance Insurance Company. The bond is there to pay consumers and workers harmed by licence-law violations; it is not liability insurance and it does not guarantee the work. The surety has filed notice to cancel this bond effective Nov 25, 2026; unless a replacement bond is filed, the licence will be suspended on that date.
Workers' comp: exempt. The contractor has told CSLB it has no employees. If a crew shows up on your job, ask for a current workers' comp certificate; a contractor with employees must carry workers' comp.
