All Illinois counties Facility information, not live custody records.

JAIL411 / LOCAL ORIENTATION ·

Use the adult jail at 2200 N. Seminary and keep contract populations, court, youth and outside systems separate.

Facility and guideStreet addressPhone
McHenry County Jail / Adult Correctional Facility →2200 N. Seminary Avenue, Woodstock, IL 60098815-338-9396

The February 2025 inspection records 650 adult beds and zero youth beds. Lake County detainees are a bounded contract population inside McHenry, not a second jail identity. The Sheriff roster excludes federal detainees and juveniles; call the jail for an excluded population. The courthouse shares 2200 N. Seminary but is not the correctional visit/mail entrance. Pace 807 serves the campus weekdays; MCRide requires an advance reservation.

Different custody systems.
Different places to start.

A Mchenry County arrest usually means the county jail. A state sentence, a federal case or an immigration hold means a different system with its own locator and rules.

Who holds someone arrested in Mchenry County?

Usually McHenry County Jail, (815) 338-9396. The arresting agency books the person and the jail holds them; ask the jail what holds are on the booking before you act on anything.

Does posting bond mean the person comes home?

Not always. A probation or parole hold, another county\'s warrant, or an immigration detainer can keep someone in custody after bond is posted. Ask the jail what holds are on the booking, and ask the bondsman what happens if there are, before you pay.

What should I confirm before visiting?

Confirm the person\'s current facility, the visiting schedule, approval requirements, accepted identification and arrival instructions. Check the facility guide before you travel.

What if I find something that needs correcting?

Send us the page and the detail that needs attention. Do not send private booking documents or other sensitive personal information.
