Legal Notice

King County has implemented Online Vendor Registration (OVR) to permit vendors, consultants and contractors to register their business with the County by creating a unique User ID, or to visit the website as a guest. The County’s ITBs, RFPs, & RFQs, with any attachments including addenda, are available for viewing by all users; but only registered firms can add themselves to plan holders lists and receive email notifications of addenda or other important information concerning the solicitation.

You must register & add yourself to the "Holders List" to be included on the official plan holders list for any specific ITB, RFP, or RFQ.
