Notes
California does not require a statewide individual ironworker license. The California Contractors State License Board (CSLB) licenses contractors (cslb.ca.gov) but not individual ironworkers. Workers typically enter the trade through union apprenticeships (Ironworkers District Council of the Pacific Northwest or local Joint Apprenticeship Training Committees). Cal/OSHA safety certifications may be required for specific tasks.
