Most of the land around O’Hare International Airport comes in parcels too small to hold a big-box warehouse. That single constraint, more than any interest-rate move or shift in the cycle, explains why the O’Hare industrial submarket continues to defy a national slowdown that has left vacant space piling up across many of the country’s outer logistics corridors.
While big-box submarkets on the metro’s edges have softened, O’Hare has stayed full. Vacancy across the broader Chicago suburban industrial market has drifted toward 8.5% to 9%, according to Dustin Albers, Senior Vice President at Lee & Associates of Illinois. In the O’Hare submarket, he said, it sits closer to 5.4% to 5.5% and the gap has held even as demand for the metro’s largest blocks has thinned.
What makes the submarket central also makes it nearly impossible to overbuild. Most lots near the airport sit under five acres, capping what any developer can deliver and keeping new supply from catching up to demand. Air freight users, pharmaceutical shippers, time-sensitive logistics operators and last-mile distributors all compete for the same narrow footprint, said Al Caruana, Executive Managing Director at Cushman & Wakefield. The result is a market that turns over in small pieces.
The geography that puts O’Hare at the center of the map is the same thing that keeps it scarce.
“It’s mostly mid- and small bay-industrial product that goes quick around O’Hare, the 10,000-to-40,000-square-foot spaces are hot right now,” Caruana said. “We’ll never have a million square footer at O’Hare.”
Albers put hard numbers to that pattern. Roughly 85% of O’Hare transactions fall in the 10,000- to 50,000-square-foot range, where leasing velocity is concentrated, he said. Mid-bay space between 75,000 and 150,000 square feet has been slower to move over the past six months and the largest blocks have been the hardest for landlords to fill. The deals getting done reflect the appetite for functional infill: STG Logistics recently signed for about 260,338 square feet, one of the year’s largest leases in the submarket, while an airline-related user Star Lux took a 91,000-square-foot sublease. On the ownership side, Sonic International bought a 40,000-square-foot building at 1951 Lively Blvd. in Elk Grove Village for $5.17 million, a rare purchase in a market where Albers estimates buildings for sale make up about 2% of available inventory.
“Many buildings lack the modern loading, clear heights, and trailer parking today’s logistics and transportation users need, which pushes larger, more sophisticated requirements to newer product in outer corridors while keeping smaller infill space in O’Hare highly competitive,” Albers said.
That migration has fueled development along the I-88 and I-55 corridors, where land is plentiful and modern bulk space can rise. In Aurora, Core Industrial Realty holds an exclusive on a 147,000-square-foot speculative building breaking ground this month for High Street Logistics Properties with 32-foot clear heights and 16 exterior docks. It’s set to deliver at the end of 2026.
Even there, Managing Broker Noel Liston said, the squeeze on smaller space persists, because manufacturers that depend on a semi-skilled labor force remain geographically limited and keep pressure on a tight infill supply of buildings under 100,000 square feet. Liston cautioned that elevated commodity prices, lingering tariffs and an inflation rate outrunning wage growth could temper warehouse demand through the back half of the year.
For the tenants making these moves, the math has shifted from operations to finance, said Rusty Parris, Managing Director of Operations Improvement at TriVista.
“Beyond just an operating decision, facility location has become a direct financial lever,” Parris said.
“Chicago serves as the center of the national industrial market, all the major railroads converge here and O’Hare is the busiest airport,” said Eric Fischer, Vice Chair at Cushman & Wakefield. “In many ways, the O’Hare submarket is the epicenter of it all, it’s just the easiest spot to get to for everybody.”
Parris said industrial manufacturers, food and beverage operators and building-products companies are increasingly treating a location near the airport as a strategic asset, one that trims safety stock, improves inventory turns and shortens lead times on both the supply and customer-facing sides.
None of the brokers expect the squeeze to ease soon. A drought of new speculative deliveries near the airport over the past 18 months has driven rents higher and Albers said annual rent growth, while moderating from about 5% to 4%, looks durable given persistent demand and a shortage of developable land. Caruana is blunter about the trajectory.
“I think the rates will never go down,” Caruana said.
Where new supply does emerge, location and tax treatment increasingly set the winners apart. Caruana and a Cushman colleague are marketing 701 Devon, a 183,000-square-foot speculative warehouse due to deliver in the fourth quarter with an Elk Grove Village address but DuPage County taxes, sparing tenants the chase for a Cook County tax incentive. Fischer said second-generation buildings move quickly too, and values on those older properties are climbing alongside the new.
Two major infrastructure projects could make an already constrained market even tighter. O’Hare’s $8.5 billion terminal overhaul is expected to generate years of activity around the airport, while the long-awaited I-490 western bypass will connect I-90, I-294 and I-390, improving access to cargo facilities and industrial properties on the airport’s south side.
“A game changer for the O’Hare submarket that’s about two years away is the opening of I-490,” Fischer said. “It’s a highway that will go around the west side of the airport and connect to I-90 on the north, I-294 on the south and I-390 just west, essentially making the interstate system around the airport contiguous.”
Caruana said the new road will hand tenants south and southeast of the airport direct access to the south cargo entrance, erasing a long detour they make today around York or Mannheim roads.
For a market defined by access and constrained by land, brokers say those improvements are likely to reinforce the same dynamic that has kept O’Hare among Chicago’s tightest industrial submarkets: plenty of demand and very little room to build.
