SB 1455 moved the date on which every licensed contractor must carry workers' comp, employees or not, to January 1, 2028; until then the exemption stands, but it becomes invalid on the first hire and CSLB must receive proof of coverage within 90 days. 16 county licenses currently show a workers' comp suspension pending.
