DeKalb County Jail Facility
The DeKalb County Jail is at 150 North Main Street in Sycamore, IL 60178. It shares the building with the sheriff's administrative offices. The jail originally had just 89 beds. That was not enough. In 2018, the county completed an expansion that brought capacity to 140 beds. The average daily population sits around 136, so the DeKalb County inmate population stays close to capacity on a regular basis.
The expansion was a big deal for a county this size. Before 2018, overcrowding forced DeKalb County to board inmates out to other facilities, which cost taxpayers more money. Now the jail can handle most of its own population. Sheriff Sullivan manages day-to-day jail operations along with patrol, civil process, and court security duties across the county.
Note: The DeKalb County Jail is a pre-trial detention facility and does not hold state-sentenced inmates long term.
