DeKalb County was formed in 1837 and named after Johann DeKalb, a Revolutionary War hero. Located west of Chicago and northwest of Kane County, its county seat is Sycamore, while DeKalb itself is the largest and most vibrant city—home to Northern Illinois University (NIU). The county enjoys a mix of suburban and rural living: DeKalb City and Sycamore offer urban amenities, shopping, and education, while outer areas remain agricultural. The housing stock is diverse, including university-area rentals, newer subdivisions, and older two-story homes. The average home price typically runs around $250,000–$330,000; suburban-style homes in Sycamore and Cortland are higher, while rural properties are lower. For those building new, the total (land + construction) often begins near $350K–$500K, especially near DeKalb’s expanding residential zones. Its proximity (~60 miles) to Chicago and Rockford gives it commuter appeal while retaining a small-town character.
