Walgreens is handing downtown Chicago a rare, turnkey prize: a massive slice of the Old Post Office that’s suddenly up for sublease. It’s a big, move-in-ready chunk at a time when Loop landlords are sweating elevated vacancies. The company frames the shift as part of a consolidation push that steers more roles back to its suburban Deerfield headquarters.
As first reported by Crain's Chicago Business, Walgreens has listed roughly 200,000 square feet at the landmark property. Hoodline flagged the planned exit Old Post Office in October, and local outlets note the company will keep its headquarters in Deerfield and intends to vacate the Loop space by January 2026, per ABC7 Chicago.
How big is the block?
Back in 2018, Walgreens took down about 200,000 square feet at the Old Post Office, with plans to house up to 1,800 employees, according to Walgreens Boots Alliance. The interiors were built as part of the building’s splashy redevelopment, with contractor Skender delivering a full build-out — a setup that leaves much of the space essentially plug-and-play for a new tenant, per REBusinessOnline.
What this adds to a crowded market
Downtown office vacancy has been grinding higher for years, and another jumbo sublease only fattens the menu for tenants. CBRE data cited by Propmodo shows the central business district creeping into the high-20% vacancy range this year — leverage tenants can feel, as owners hustle to polish and pitch their top-tier space.
Why now
The shake-up follows a bigger corporate plot twist: Sycamore Partners closed its acquisition of Walgreens Boots Alliance in late August, according to Walgreens Boots Alliance. The company says it’s refocusing investment on stores and customer experience — and, as it told ABC7 Chicago, “we have made the decision to exit our office space at the Old Post Office.”
What's next for the building
It’s not yet clear whether Walgreens will run a straight sublease play or try for an early lease termination. The Real Deal reports the lease runs through 2032, and building owner 601W Companies isn’t commenting. Either way, a big, high-quality block like this will be front and center in downtown leasing chatter — and likely show up in a few lender memos, too.
For Loop brokers and corporate real estate teams, the listing is a live-fire test of demand for large floorplates downtown. Expect the tours, teasers, and pitch decks to ramp up fast as the space hits the market.
