Small purchases

Purchases of goods and services costing $3,000 or less for federal funding or $10,000 or less for non-federal funding require one quotation.

Informal solicitations

For most purchases estimated to be between $2,000 and $150,000 for construction, Purchasing staff will issue a request for verbal or written quotations to vendors. Verbal quotations may be given over the telephone or may be requested and replied to via fax. Written quotations will be received until the specified day and time indicated on the request.

Formal solicitations

An Invitation for Bids (IFB) or a Request for Proposals (RFP) is used for purchases of goods and services estimated more than $150,000. As a general rule, an IFB is used for construction projects estimated more than $150,000.

Anyone interested in obtaining an IFB or RFP should contact the appropriate Buyer/Contract Administrator in the Purchasing division. Sealed bids/proposals must be received and time stamped by the Purchasing division prior to the submittal deadline. All late bids/proposals are returned to the vendor/offeror without being opened. Public bid openings are held in Seattle Housing Authority's Central Office at the specific time and date stated in the IFB. During the bid opening, only the name of the vendor and total amount is read aloud. Vendors are welcome to attend the bid openings.


Seattle Housing Authority utilizes the Small Works Roster maintained by the Municipal Research Services Center (MRSC) for its small construction/maintenance contracts estimated at $300,000 or less and the Consultant Roster maintained by the Municipal Research Services Center (MRSC) and the City of Seattle for its small consultant/services contracts estimated at $150,000 or less.

Payment for goods and services

Seattle Housing Authority will generally issue payment for goods and services received within 30 days of receipt of an invoice or pursuant to the terms of the specific contract, if different from this general policy.

  • Seattle Housing Authority may cancel or withdraw a solicitation in whole or in part and reject any and all bids or proposals at any time prior to an award.

  • Seattle Housing Authority advertises its formal solicitations in the Daily Journal of Commerce.

  • Vendors may also check the local plan centers for information on current purchasing activities.

  • Address all shipments according to the Delivery Instructions on the purchase order.
