Washington L&I contractor registrations (data.wa.gov)

Washington State Department of Labor & Industries (L&I) contractor registrations, from the register L&I publishes on data.wa.gov and reloads three times a day: about 162,000 construction, electrical, plumbing and elevator contractor registrations, current and past. Search by business or principal name, registration number, UBI, city, ZIP, licence type, specialty, status and effective, expiry or suspension date, newest first; read one registration joined with its principals, liability insurance and authorized permit signers. Open data (PDDL and Public Domain per dataset): every record carries its licence, attribution and L&I Verify link. Bonds are left out because their dataset carries no licence.
