400 W Ontario St

An 18-story concrete residential condominium completed in 1999, this River North midrise mixes loft-scale interiors with full-service condominium conveniences. Units are primarily one- and two-bedroom floor plans that emphasize open sightlines and generous ceiling heights; many residences feature hardwood floors, large picture windows, private balconies, and in-unit laundry. Kitchens commonly include granite or quartz counters, 42" cabinetry, and stainless appliances; master suites frequently offer en-suite baths and walk-in closets. The property’s common areas are staffed 24 hours with a manned lobby and on-site management, and residents use a fitness room, bike storage, additional rentable storage lockers, and a roof deck and outdoor grilling area. Parking is offered as deeded heated garage spaces at an additional cost. Exterior details include a monitored entry system and furnished roof deck; pet policies are friendly as noted in listings. Located on the quieter west end of Ontario Street within walking distance of River North restaurants, galleries, the Chicago River, parks and transit, the building caters to buyers seeking downtown convenience paired with apartment-scale living rather than tower-scale verticality.
