Chicago’s 1.2 billion-square-foot industrial market has weathered the Great Recession and is now showing strong growth through expansion of the region’s traditional boundaries and by way of redevelopment in landlocked areas. At the center of this trend is O’Hare International Airport — sixth in the nation and 17th in the world in air cargo tonnage. All totaled, the O’Hare industrial submarket contains 103 million square foot of product. Since the vacancy rate peaked at approximately 13 percent in 2010, the O’Hare industrial submarket has rebounded in a big way. In fact, the submarket has recorded positive absorption every year since 2011. The vacancy rate fell to 7 percent in 2014 due to an improving economy and the aggressive deal making of the larger industrial owners such as Prologis, KTR and Hamilton Partners.
