EEO Certification Requirement

Multnomah County's PCRB Rule 60-0040 requires that all contractors furnishing goods and services to the County in excess of $75,000 must be certified as an Equal Opportunity Employer. (This dollar amount may vary for other government agencies).  Contracts in excess of $75,000 are subject to the County’s Equal Employment Opportunity (EEO) requirements and will include vendor certification as indicated in the Sample Multnomah County Contract.  The County will not execute a contract over $75,000 with any contractor who fails to become certified.

Supplier Preference

As indicated in the specifications contained in our solicitations, Multnomah County shall prefer, all else being equal, goods produced in the State of Oregon. For more information please refer to project specifications.  The State of Oregon has also enacted a "reciprocal preference law." The law requires that, when determining the lowest responsible bidder, Multnomah County must add a percent increase to each nonresident bidder's price equal to the percent of preference given to local bidders in the nonresident bidder's home state.  The following link gives more information on the law and provides access to the most current information of states with preference laws: Reciprocal Preference Laws by State.
