Washington Contractor License Lookup & Scraper: new WA contractor leads (businesses only)

Get a daily feed of new and renewed Washington State contractor licenses from the official WA Department of Labor & Industries (L&I) open data on data.wa.gov. It covers construction, electrical, plumbing and elevator contractors. Each result is a business entity (LLC, corporation, LLP, partnership or joint venture) with its license number, license type and status, effective and expiration dates, specialty (General, Specialty, Residential...), UBI number, city and ZIP, business address and phone, and a link to the L&I verification page.

No scraping, no browser, no proxies. The Actor reads the state's open-data API, so runs take seconds. The data refreshes daily.

Who uses this

• Suppliers, distributors and equipment-rental reps selling to newly licensed contractors.
• Insurance, bonding, payroll and accounting firms reaching new contracting businesses.
• General contractors recruiting licensed subs by trade and area.
• Compliance and KYB teams checking license status in bulk.

Privacy by design

• Sole proprietors (L&I type "Individual") and trusts are always excluded, because their names are personal names.
• Every kept business name must carry a legal-entity marker (LLC, Inc, Corp, LLP...).
• The principal/owner name column is never requested from the API.

FAQ

Is this legal to use? Yes. The source is the State of Washington's official open-data portal. The dataset "L&I Contractor License Data - General" is published under the Open Data Commons Public Domain Dedication and License (PDDL).

Does "effective date" mean a brand-new license? It means the start of the current license term, so the results include both new licenses and renewals. A UBI number you haven't seen before usually indicates a new business.
