About the community
McCook is a village in Cook County, Illinois, and an industrial suburb of Chicago. As of the 2020 census its population was 249, the lowest of any municipality in the county. Despite that tiny population, McCook is home to a large amount of heavy industry, including portions of the Vulcan Materials McCook Quarry, the UOP complex, and the Electro-Motive Diesel locomotive plant, which gives the village an unusually large tax base. McCook is also the namesake and home of the McCook Reservoir, a centerpiece of the regional Tunnel and Reservoir Plan, the Deep Tunnel flood-control system. Historic Route 66, Joliet Road, runs straight through town, and commuters benefit from immediate access to I-55, IL-171, and Midway Airport a few miles east, plus nearby BNSF Metra service in La Grange.

McCook sits in southwestern Cook County along the Des Plaines River valley, roughly 12 miles southwest of downtown Chicago in the Lyons Township area.
McCook is, first and foremost, an industrial village. With a 2020 census population of just 249, it is the smallest municipality in Cook County by population, and its land is dominated by heavy industry: the Vulcan Materials limestone quarry, the UOP complex, and the sprawling Electro-Motive locomotive works. The residential community is correspondingly small and tight-knit, with about 105 households and an average household size above three. This is not a bedroom suburb of subdivisions and shopping centers, it is a working village where homes sit close to active industry.
What McCook lacks in size it makes up for in location and character. Historic Route 66, Joliet Road, runs straight through town, lined with surviving roadside landmarks like the Welcome to Fabulous McCook neon sign, a nod to the famous Las Vegas original, and the Steak N Egger diner in a 1926 Joliet-limestone building. Commuters benefit from immediate access to I-55, IL-171, and Midway Airport just a few miles east, plus nearby BNSF Metra service in La Grange. Resident workers reported an average commute of about 22 minutes, shorter than the national average.

How McCook got here
The area that became McCook began as a farming district on the road to Joliet, with wooded and marshy land along the Des Plaines River to the south. In the 1880s quarries opened and limestone was extracted and shipped out via the Illinois and Michigan Canal and by rail. The village was named for John J. McCook, a Civil War officer who later became a director of the Santa Fe Railroad, and a McCook station served the railroad in town. The village incorporated in 1926, the same year U.S. Highway 66 was created, and Route 66 was aligned through the village in 1928.
Despite the Great Depression, industry took root: the Electro-Motive Company, a General Motors subsidiary, built a locomotive plant here in 1935 and produced most of its locomotives there for decades. Known as the LaGrange plant for its mailing address because McCook has no post office of its own, the facility went on to build tens of thousands of diesel-electric locomotives sold worldwide. In 1995 the former Universal Oil Products Riverside Laboratory in McCook was designated a National Historic Chemical Landmark.

Your local agent
Most agents will list anything. I focus on the communities I actually know, and the details that determine resale value here aren't in the MLS write-up: which lots back to open space, which streets carry the most consistent demand, which floor plans buyers ask for by name, and what each HOA actually covers.
When you're ready to tour or list, you want someone who's walked the streets, talked to the residents, and read the last 50 closed comps in this market specifically. That's how I work. Text or call any time, and I'll give you a real take, not a brochure.
Thinking of selling?
Not a Zestimate. A real CMA from someone who's sold this neighborhood, knows the floor plan premiums, and can tell you which upgrades the buyer pool here actually pays for.
