What this means

The licence is suspended because the required liability insurance lapsed. 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: Workers' Compensation Insurance with National Liability And Fire Insurance Company, policy through Apr 15, 2027.
