La Salle County, established in 1831 and named after the French explorer René-Robert Cavelier, Sieur de La Salle, stretches across north-central Illinois. The county seat is Ottawa, while Peru, La Salle, Mendota and Streator serve as key population centers. This is a diverse county geographically and economically — it hosts parts of the Illinois River Valley, rich farmland, historic canal towns, and modern industry. Ottawa and Peru anchor small-city living with shopping, hospitals and schools; while outer towns such as Earlville, Sheridan, and Serena retain rural character. Housing varies accordingly: historic Victorian homes downtown, mid-century subdivisions near the river, and farmhouses along country roads. According to Zillow and Redfin data (2025), median home values hover around $210,000 – $270,000, with newer homes or river-view lots reaching $350K+. Building a home (including land and utilities) typically costs $300K – $450K, depending on location and finish. The county is mainly semi-rural but benefits from proximity to larger metros — Chicago lies about 90 minutes east, Peoria about 90 minutes southwest. La Salle County offers a balanced lifestyle of affordability, space, and heritage — a place where river bluffs and farmland meet comfortable Midwestern communities.
