About County Jails in Illinois
Understanding county jails in the Illinois
Welcome to the most complete and up-to-date directory of county jails and correctional facilities in Illinois. This page lists every active county-level detention facility operating across Illinois, providing families, attorneys, bail bondsmen, social workers, and the general public with fast, reliable access to accurate information about county-level incarceration. County jails are often the first longer-term facility a person is sent to after initial arrest and police booking, making this directory essential for anyone trying to locate a recently arrested loved one.
What Are County Jails and How Do They Work?
County jails in Illinois are local correctional facilities operated by the county sheriff's office or county department of corrections. They serve as the primary point of longer-term detention for individuals awaiting trial, unable to make bail, or serving shorter sentences for misdemeanor offenses.
The county jail system is decentralized — each county operates its own facility tailored to its population size, court system, and law enforcement needs. This means county jails vary significantly in size, capacity, programming, and conditions.
How County Jails Differ From Other Facilities
- County Jails: Operated by sheriff's office. Hold pretrial detainees, those unable to make bail, misdemeanor sentences under one year.
- City/Municipal Jails: Operated by city police. Shorter holds immediately after arrest before county transfer.
- Police Lockups: Short-term holding (24-72 hours) during initial booking and processing.
- State Prisons: Operated by Illinois's DOC for felony sentences over one year.
- Federal Prisons: Operated by Federal Bureau of Prisons for federal crimes.
Types of County Correctional Facilities
- County Jail: Standard county detention facility serving the general pretrial and sentenced misdemeanor population.
- County Correctional Center: Larger facility with expanded programming, multiple housing units, and specialized services.
- County Detention Center: Often houses higher proportion of pretrial detainees or federal contract inmates.
- County Work Release Center: Minimum-security allowing day employment with evening return.
- County Medical/Mental Health Facility: Specialized units for inmates requiring ongoing medical or mental health care.
- County Honor Farm: Minimum-security where inmates perform outdoor work assignments.

You can also use our free US inmate locator tool to search across all county jails simultaneously.
Visitation
Policies vary considerably — some jails offer in-person contact visits, others have non-contact or video visitation only. Check visitation rules for the specific facility before planning a visit. Click any facility to view its complete visitation guidelines.
Calling an Inmate
Phone calls are outbound only from pre-approved numbers. Your number must be registered with the facility's phone provider and a prepaid account funded. Read our calling guide for complete setup instructions.
Getting Bail
Once bail is set at arraignment, pay it directly to the county jail or court, or work with a licensed bail bondsman who will post bail for a fee of 10-15% of the total amount.
Programs Available
Larger county jails typically offer GED and literacy programs, substance abuse counseling, religious services, and sometimes vocational training. Program availability varies significantly by facility size and resources.
Sheriff's Role
In most counties, the sheriff's office operates and manages the county jail. The sheriff is accountable for safe, humane, and legally compliant operation, including staffing, programming, medical services, and state/federal compliance.
Release & Reentry
Release can happen through bail, sentence completion, dismissal of charges, or court order. The transition back to daily life requires planning for employment, family reconnection, court-ordered supervision, and financial stability.
