Tenants are committing or recommitting to quality space, investors are acquiring assets at more compelling valuations and office-to-residential conversions are removing obsolete supply. Leasing activity pulled back in the first quarter of 2026, with approximately 1.6 million square feet of direct deals completed, according to Bradford Allen’s first-quarter downtown Chicago office market report. That is down from just over 2 million square feet in fourth-quarter 2025. Several notable transactions reflect a market increasingly defined by location and building quality. Global food brand Mars Snacking made the quarter’s most significant commitment, signing a new 169,816-square-foot headquarters lease at Fulton Labs, 400 N. Aberdeen St. in Fulton Market, while also absorbing the 37,672-square-foot former Kellanova space in River North as part of a broader expansion that will bring more than 600 new jobs and $100 million in investment to the city.

Gilbane Development Breaks Ground on Office-to-Residential Conversion Project in Arlington, Virginia
ARLINGTON, VA. — Gilbane Development has begun the conversion of a six-story, 121,200-square-foot vacant office building at 3601 Wilson Blvd. in Arlington’s Virginia Square neighborhood. Dubbed Renley, the redevelopment will deliver 94 multifamily units in one- through three-bedroom configurations. Situated adjacent to the Virginia Square-GMU Metro station, Renley is one of the first projects to leverage Arlington County’s updated adaptive reuse policy, which was adopted in November 2024. The policy was designed to streamline office-to-residential conversions and create incentives for developers to bring underutilized office buildings “back to life.” Renley is targeted for completion in April 2027. Gilbane Development originally acquired the property in March 2025. The redevelopment plan will preserve the building’s exterior, while updating the entire interior. Resident amenities will include a wellness center, coworking spaces, lounges, gathering areas and tenant storage on every floor. Renley will also offer 5,637 square feet of ground-floor retail space and 207 parking spaces located in an underground garage.
