Cook County and City of Chicago Certification Reciprocity

Cook County Board President Toni Preckwinkle and City of Chicago Mayor Rahm Emanuel have launched a reciprocal Minority and Women Business Enterprise initiative.   This initiative will allow your business to be certified by either the County or City and have either certification apply to both agencies.  This combined effort for the County and City will lessen the financial burden and streamline the certification process by providing a “one stop shop” for MBE/WBEs interested in participating in County and City procurement opportunities.  Provided that the agency’s requirements are met, you will no longer be required to submit your annual No Change Affidavit or ReCertification Affidavit to both agencies, just one.

For bids or proposals, professional services or non-construction firms certified with the City of Chicago, a MWBE Reciprocal Certification Affidavit must be submitted with the City’s letter of certification.  This form ensures that the certified MBE/WBE firms participating in Cook County contracts for credit are within the parameters of the Cook County Procurement Ordinance.

Please note that if you are currently certified with the City of Chicago in a non-construction area i.e., professional services or goods, the County Code requires: 1) the firm’s average annual gross receipts over the five most recent years does not exceed the U.S. Small Business Administration’s Size Standards and, 2) the personal net  worth of the qualifiying (51%) individual(s) does not exceed the County’s personal net worth limitations of approximately $2.2M.

Please contact our office at 312-603-5502 for questions regarding the County and City’s reciprocal Minority and Women Business Enterprise initiative and Cook County’s certification processes.
