Grundy County, formed in 1841 and named after U.S. Senator Felix Grundy, sits in northeastern Illinois along the I-55 corridor. The county seat is Morris, a vibrant town with a charming historic downtown and growing residential suburbs. Other communities include Coal City, Minooka, and Gardner. The county benefits from its proximity to the Chicago metropolitan area (about 60 miles southwest), giving it a mix of suburban and rural appeal. Housing includes new subdivisions, small-town family homes, and rural estates. The average home price ranges from $290,000–$400,000, with luxury or newer builds exceeding $500,000. New construction costs with land typically run $400K–$600K, depending on finishes. The county’s industrial strength and access to Chicago make it ideal for commuters who want space and affordability without losing big-city access.
