Source: CSLB Public Data Portal, License Master file dated Oct 20, 2026. Status can change at any time, so confirm it with CSLB's Instant License Check before you sign. A CSLB record doesn't show general liability insurance, so ask for a certificate. The License Verified stamp means the license was active in that day's file with no CSLB flag on it. It isn't a rating, a recommendation, or a promise about workmanship.
