Kendall County IL Jail basic information to help guide you through what you can do for your inmate while they are incarcerated. The facility's direct contact number: 630-553-7500

The Kendall County IL Jail is a medium-security detention center located at 1102 Cornell Ln Yorkville, IL which is operated locally by the Kendall County Sheriff's Office and holds inmates awaiting trial or sentencing or both. Most of the sentenced inmates are here for less than two years. Kendall County accepts inmates from surrounding towns, municipalities, the US Marshal's Service and the Yorkville Police Department who do not have their own long-term lock-up.

The Corrections Division of the Kendall County Sheriff’s Office is comprised of two special areas. The largest section is the County Jail, the other is Inmate Transportation. The Corrections Division currently has 42 Deputies assigned to the Division.

The Kendall County Jail provides for the custody of individuals awaiting trial, serving sentences up to one year, or sentenced to periodic imprisonment. The Kendall County Jail was opened in 1992 with a capacity of 60 beds. In 2000, the Jail was renovated and an additional 24 beds were added. In late 2005, a new wing was constructed and 119 beds were added to the jail creating a new jail capacity of 203 beds.

The Transportation Team is responsible for transporting Inmates to and from Court, other Jails, and Medical Facilities.
