Sheriff offices in Illinois are independently elected county agencies responsible for law enforcement, jail operations, and civil process service. Each county in Illinois elects its own sheriff, who serves as the chief law enforcement officer for that county's unincorporated areas.
Sheriff locations are available in 115 cities across Illinois. They are spread across 102 counties.
Cities with the highest concentration of sheriff office listings include Belvidere, Princeton, Paxton, reflecting the population centers where multiple sub-offices or specialty divisions may be located.
Illinois residents should note that sheriff offices handle civil law enforcement functions — such as serving eviction notices and foreclosure papers — in addition to criminal law enforcement, so the sheriff office is often the correct point of contact for civil legal matters at the county level.
