Cook County has 181 designated Qualified Opportunity Zones, by far the most of any Illinois county, spanning Chicago neighborhoods across the South Side, West Side, and select north side communities, as well as suburban Cook County municipalities. Chicago's OZ footprint covers neighborhoods including Englewood, Auburn Gresham, Austin, Humboldt Park, Woodlawn, South Shore, East Garfield Park, and North Lawndale, historically disinvested communities that are now attracting growing investor attention.
Cook County's OZ investment landscape is among the most diverse in the nation. Major investment themes include workforce and market-rate multifamily housing across Chicago's south and west sides; industrial redevelopment in the city's legacy manufacturing corridors; mixed-use projects in neighborhoods adjacent to the University of Chicago and Obama Presidential Center development in Woodlawn; and suburban Cook County logistics and light manufacturing. Chicago's extensive transit network, anchor institutions, and deep capital markets make it the most active OZ market in the Midwest.
What is an Opportunity Zone census tract?
Each Opportunity Zone is defined at the census tract level by the U.S. Census Bureau. Investors must deploy eligible capital gains into a Qualified Opportunity Fund (QOF) that invests in property or businesses within these designated tract boundaries. The tract GEOID numbers listed above identify each designated zone in Cook County.
How do I invest in Cook County Opportunity Zones?
Investments must be made through a Qualified Opportunity Fund (QOF). Capital gains must be reinvested within 180 days of the gain recognition event. Consult a qualified tax advisor to determine your eligibility and structure your investment. You can also visit our Find OZ Help page to connect with an OZ specialist.
