(30 ILCS 500/45-10)

Sec. 45-10. Resident bidders and offerors.

(a) Amount of preference. When a contract is to be awarded to the lowest responsible bidder or offeror, a resident bidder or offeror shall be allowed a preference as against a non-resident bidder or offeror from any state that gives or requires a preference to bidders or offerors from that state. The preference shall be equal to the preference given or required by the state of the non-resident bidder or offeror. Further, if only non-resident bidders or offerors are bidding, the purchasing agency is within its right to specify that Illinois labor and manufacturing locations be used as a part of the manufacturing process, if applicable. This specification may be negotiated as part of the solicitation process.

(b) Residency. A resident bidder or offeror is a person authorized to transact business in this State and having a bona fide establishment for transacting business within this State where it was actually transacting business on the date when any bid for a public contract is first advertised or announced. A resident bidder or offeror includes a foreign corporation duly authorized to transact business in this State that has a bona fide establishment for transacting business within this State where it was actually transacting business on the date when any bid for a public contract is first advertised or announced.

(c) Federal funds. This Section does not apply to any contract for any project as to which federal funds are available for expenditure when its provisions may be in conflict with federal law or federal regulation.
