About the Jail

The current Lake County Sheriff’s Adult Corrections Facility opened March 10, 1989, replacing a 20-year old facility, and operates under the direction of the Lake County Sheriff and his correction’s management team.


In October 2016, the Lake County Jail successfully garnered its fourth consecutive accreditation from the American Correctional Association. Standards set by ACA reflect practical up-to-date policies and procedures and function as a management tool for agencies and facilities throughout the world. In addition, the Adult Corrections Facility earned the accreditation of the National Commission on Correctional Health Care for the provision of health services in December 2016.

The Accreditation Advantage

Advantages of being an accredited facility include improvement of staff training and development, establishing measurable criteria for upgrading operations, improving staff morale and professionalism, creating a safer environment for staff and offenders, providing performance-based benefits and reducing liability insurance costs. The Adult Corrections Facility also complies with the Federal Prison Rape and Elimination Act (PREA). Learn more about PREA and the Lake County Sheriff's Office commitment to PREA compliance.

On August 22, 2016, the Adult Corrections Facility was found in full compliance with the Illinois County Jail Standards. 

Sentencing Limit

According to Illinois law, an inmate may be sentenced to a county jail for no more than 364 days. The Adult Corrections Facility maintains the capacity to house 740 inmates.
