4240 N Keystone Ave

A low-rise, four-story condominium complex built in 1970, located in Chicago’s Old Irving Park neighborhood. The structure uses concrete and flexicore construction for solid sound separation and durability; many units feature balconies that overlook tree-lined streets. Common interior elements include a secure lobby with elevator access, first-floor bedroom configurations in some layouts, on-site storage rooms, and a shared party/meeting room in the basement. Unit footprints vary from compact one-bedrooms—some approaching 900 square feet with corner exposures—to larger two-bedroom end units with expansive living areas and private master suites. Kitchens are typically updated in listings with granite or solid-surface counters and stainless appliances; many homes include in-unit full-size laundry. Exterior provisions include assigned off-street parking with guest spaces and plowed lots accessed from an alley. The association handles heat, water, snow removal, landscaping, and common insurance in many cases, and maintains healthy reserve funds. Proximity to transit and highways is a defining locational trait: short walks to the Blue Line and Metra, and quick access to the 90/94 expressway, placing daily errands, restaurants, and parks within easy reach.
