A series of four programs adopted by the city of Chicago (state of Illinois) in 2011-2012 provide for local price preferences in the city's procurement practices. They are as follows:
- Small Business. Initiative. Established October 2011, designed to encourage small businesses to participate in City-funded construction projects, under $3 million in total cost. This is a program allowing small local businesses to be exclusive bidders on certain construction projects.
- In August 2013, in response to the vendor community, a second tier, SBI II, was developed, for construction projects valued at $2 million or less, open to local firms that are one-half the size standards of the Federal government's Small Business Administration.
- Local Manufacturing Ordinance. Adopted in February 2012, it provides bid incentive to bidders providing goods made or assembled in the City of Chicago.
- Local Business Preference Ordinance. Adopted in February 2012, expanded local business preference to all City funded contracts over $100,000.
