Vendors Not Allowed to Bid (Debarment)

Information about the vendor debarment process, including the contractors that are not allowed to bid on public works projects.

Vendor debarment

A business or individual vendor that commits an ethical breach or illegal action can be barred from bidding on or entering into a contract with the state for up to three years. The legal term for this is debarment. Debarment helps ensure a vibrant, open, and competitive procurement marketplace for bidders and the state of Washington.
