Where to Start for Ingham County Records
For adult jail custody, the public facility is the Ingham County Correctional Facility at 640 N. Cedar Street, Mason, MI 48854. General jail information is available through 517-676-2431 option 2, and the sheriff's main number is 517-676-2431. The sheriff's general office address is 630 N. Cedar Street, Mason, MI 48854. The sheriff corrections page lists jail lobby hours as Monday through Thursday, 7:00 a.m. to 10:00 p.m., and Friday, 7:00 a.m. to 7:00 p.m.; confirm holiday or special closures before traveling. Medical or medication questions for someone in the jail should go to the medical department at 517-676-8359.
Use these official routes when the topic is more specific:
- For a current adult jail lookup, start with the jail inmate records guide or the official Ingham County Inmate Locator.
- For booking photo access and limits, use jail roster mugshots and the Ingham County FOIA Center when a record is not posted online.
- For charges, hearings, or case filings after an arrest, use court records after a jail arrest or the official court-record system at courts.ingham.org. The sheriff FOIA page routes court records to the courts.
- For a facility-specific question, use the pages for the Ingham County Correctional Facility and the Ingham County Youth Center.
- For a sentenced state prisoner, search Michigan Department of Corrections OTIS rather than the county jail roster.
- For federal or immigration custody, use the official BOP inmate locator or ICE Online Detainee Locator System.
If the issue involves the Ingham County Prosecuting Attorney, the research source lists John Dewane as prosecutor and points to the prosecutor's office at pa.ingham.org for office contacts, hours, and victim/witness information.
