401 E Ontario St

A 48-story residential high-rise completed in 1990, this full-service condominium sits in Chicago’s Streeterville neighborhood and offers one- and two-bedroom residence types. The tower presents a traditional concrete-and-glass profile typical of late-20th-century urban developments, with large bay and corner windows that emphasize views. Interiors commonly feature hardwood floors, high ceilings or cathedral ceilings in select units, built-ins and bookcases, granite or quartz counters, and walk-in closets; many listings note opportunities for renovation or contemporary upgrades. Shared spaces are extensive and include a staffed lobby with 24-hour door/security service, an exercise room, sauna, indoor pool and hot tub, two sun decks/roof deck, party room, and laundry facilities; some units allow in-unit washer/dryer installation. Building services extend to monitored entry/TV door systems, on-site management and available garage parking (typically deeded or sold with units). Exterior amenities and maintenance include lighting, cable access, storage lockers and storm/screen protections. The property is pet-friendly and positioned within walking distance of Ohio Street Beach, Navy Pier, the Magnificent Mile, Riverwalk and multiple transit routes, supporting an active urban lifestyle with immediate access to restaurants, shopping, cultural venues and Northwestern medical and campus destinations.
