Peoria County, one of Illinois’ most dynamic regions, was established in 1825 and named after the Peoria Native American tribe. The county seat and largest city is Peoria, a historic and cultural hub located on the Illinois River. The area has evolved from its industrial roots into a modern city with strong healthcare, education, and technology sectors. The county’s housing varies widely — from historic homes near the Peoria Heights bluff to modern suburban neighborhoods in Dunlap and Edwards. Median home prices are about $180,000–$260,000, with upscale or river-view homes reaching $400K+. Building new homes (including land) costs $300K–$450K, depending on location and finish. The city of Peoria provides urban amenities — hospitals, universities, museums, and dining — while outer towns like Brimfield and Kickapoo retain small-town comfort. Peoria County is ideal for professionals and families who seek urban living blended with Midwestern affordability and strong community culture.
