How licensing works in Washington
Washington registers construction contractors with L&I rather than licensing general contractors by trade, and publishes a live status for each. Around a third of the register is expired or suspended at any time, so the status matters more here than the expiry date alone.
The Washington State Department of Labor & Industries publishes its licensee file as public record, and we reload it every day. A license belongs to a named individual or company and stops being valid when it lapses, is suspended, or is not renewed. The record usually stays in the published file after that, which is exactly why lapsed licenses are visible here rather than quietly disappearing.
