What this means

The licence is suspended because the workers' compensation policy lapsed with no replacement or exemption on file. A suspended licence cannot be used to contract for work until CSLB lifts the suspension.
Contractor's bond: $25,000 with American Contractors Indemnity 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.
Workers' comp: CSLB has no current workers' comp policy or exemption on file for this licence.
