The West Cook submarket draws companies from the City of Chicago looking for more functional buildings and additional amenities compared to the aging–often obsolete–inventory in Chicago. Companies also migrate to the area from the neighboring O’Hare submarket where interstate and airport access is comparable, but rental rates tend to be higher. West Cook benefits from convenient access to the City of Chicago, close proximity to area interstates & rail providers, and relatively low rental rates. It is primarily an owner/user market, but leasing opportunities have increased as institutional and private owners have entered into the submarket.
