Bay County Arrest Records
Bay County arrest records are public documents that detail law enforcement contacts in this mid-Michigan county along Saginaw Bay. Bay City, the county seat, is one of the larger cities in the Saginaw Bay region. Arrest records here are maintained by the Bay County Sheriff's Office and are also accessible through Michigan's ICHAT criminal history system, the court case search portal, and FOIA requests to local and state agencies. This page explains how to find these records.
Bay County Overview
How to Search Bay County Arrest Records
Bay County is located on the western shore of Saginaw Bay in mid-Michigan. Bay City is the county seat and the most populous city. The county is bordered by Saginaw County to the west, Midland to the north, Arenac to the northeast, and Tuscola to the south. Bay County has more urban character than many mid-Michigan counties, with active law enforcement from the Bay County Sheriff, Bay City Police Department, and other local agencies.
Arrest records in Bay County are public under MCL 15.231. The main access options are the Bay County Sheriff at 989-895-4050 (website: baycounty-mi.gov), the ICHAT statewide background check at apps.michigan.gov, and the Michigan court case search at courts.michigan.gov. The sheriff and jail have the most local detail. ICHAT covers the full state criminal history. Court search gives you case-by-case filing and disposition data.
Bay County's higher population compared to many northern Michigan counties means more active arrest records and a higher volume of court filings. All are searchable through the tools listed here.
Bay County Sheriff's Office and Jail
The Bay County Sheriff's Office is located in Bay City and can be reached at 989-895-4050. The sheriff's website is at baycounty-mi.gov. The office operates the Bay County Jail, which holds people arrested in the county pending court or serving shorter sentences. The sheriff handles patrol in unincorporated Bay County and provides services to several townships through contracted arrangements.
Booking records from the Bay County Jail are public records under MCL 15.231. To get a copy, submit a written FOIA request identifying the person and arrest date. The office has five business days to respond. Standard arrest information is public. Some active investigation details or victim information may be withheld. If someone was booked into the Bay County Jail and released, the booking record still exists and is public even after release.
For current jail population, call the sheriff at 989-895-4050. Staff can confirm whether a specific person is currently in custody. This is faster than a formal records request if you just need to know custody status. The Bay County Jail typically holds a mix of pre-trial detainees and sentenced inmates serving short terms.
Bay City Police Department maintains separate records for arrests made by city officers. If the arrest happened in the city of Bay City, you would need to contact the city police department directly for city police records. The Bay City Police are reachable through the city's main contact page. FOIA requests to the city police follow the same MCL 15.231 rules as requests to the county sheriff.
ICHAT: Bay County Criminal History Search
ICHAT is the state's primary tool for public criminal background checks. It is run by the Michigan State Police under MCL 28.241, covers all 83 counties including Bay, and costs $10 per search. Access it at apps.michigan.gov by entering name and date of birth.
An ICHAT result covers a person's full Michigan criminal history. If someone has cases from Bay County, Saginaw County, and Midland County, all of that appears in one report. This is more thorough than a single-county search. Results include convictions and charged offenses that resulted in court filings. The report comes back quickly after payment.
ICHAT does not include arrests that did not lead to charges. Juvenile records are excluded. Records set aside under Clean Slate law are removed. These are important limits to understand. ICHAT gives you the formal conviction and charging history, not a log of every police contact.
The Michigan court case search tool above covers Bay County circuit and district court filings. It is free to use and updated as cases progress.
Michigan Court Case Search for Bay County
Bay County felony criminal cases go through the 18th Circuit Court in Bay City. Misdemeanors and civil infractions are handled by the Bay County District Court. Both court levels appear in the free Michigan public court case search at courts.michigan.gov/case-search/.
Search by name or case number. Results include case type, charges filed, court events, and final outcome. This tool is updated more frequently than ICHAT and is a good way to track active or recent cases. If someone was arrested in Bay County recently and charges were filed, the case will appear here within a short time of arraignment.
For civil cases, civil court records also appear in the same system. You can filter by case type to look only at criminal matters. The circuit court handles felonies. The district court handles misdemeanors, small claims, and traffic cases. All are publicly searchable unless a court order seals a specific file.
The Bay County courts are active given the urban population. Criminal filings in Bay County are more numerous than in rural northern Michigan counties. The court case search system handles the higher volume and is updated regularly by court staff.
FOIA Requests for Bay County Police Records
Michigan FOIA (MCL 15.231) lets the public request records from any public agency. Arrest records, police reports, jail logs, and incident reports from the Bay County Sheriff and local police departments are all subject to FOIA. Submit a written request that identifies the records as specifically as possible. Include name, date, and case number if available. The agency has five business days to respond.
For MSP records from the Bay City area post, use the MSP FOIA portal at michigan.gov/msp/services/foia. The MSP FOIA office phone is 517-241-1934. MSP patrols I-75 and other state routes through Bay County. Incidents on those roads produce MSP records, not county sheriff records.
Submit FOIA requests for MSP records from Bay County incidents through the portal shown above. The MSP responds within five business days.
OTIS: Michigan Department of Corrections Records
OTIS, the Michigan Department of Corrections' Offender Tracking Information System, is a free public database at mdocweb.state.mi.us/otis2/otis2.html. If someone arrested in Bay County was convicted of a felony and sentenced to state prison, their record appears in OTIS. Search by name to find photos, commitment offense, sentence length, facility, and parole status.
OTIS does not include county jail inmates. It only covers people in the Michigan state prison system under MDOC jurisdiction. Given Bay County's urban population, OTIS is more likely to show Bay County cases than a smaller rural county. The system is updated regularly and gives a clear picture of where someone stands in the state corrections system.
Sex Offender Registry in Bay County
Michigan's Sex Offender Registry (MCL 28.721) is managed by the MSP and is free to search at mspsor.com. Filter by Bay County to see all registered sex offenders in the area. The registry shows name, photo, current address, conviction offense, and registration tier. Registrants in Bay County must check in regularly with local law enforcement.
Bay County, as an urban county, has more registrants on the sex offender registry than many rural Michigan counties. The MSP site is the official and most up-to-date source. Use the official site when you need accurate information about a specific person or address. Third-party registry lookup sites pull from this data but may not be current.
OTIS above covers Bay County felony convictions that resulted in state prison sentences. It is free and updated by MDOC regularly.
Michigan Clean Slate Law and Expungement in Bay County
Michigan's Clean Slate law (MCL 780.621g) expanded expungement eligibility significantly in 2021. Many misdemeanors and some felonies can now be set aside. Some low-level convictions are automatically set aside after a waiting period without new offenses. When a conviction is set aside, it is removed from ICHAT and most public searches.
For Bay County residents, the expungement petition is filed with the 18th Circuit Court in Bay City. The clerk's office has forms. Bay City Legal Aid or other local legal services may help people who can't afford an attorney. The Michigan Legislature site at legislature.mi.gov has the Clean Slate statute in full so you can check eligibility before you file.
Not all offenses qualify. Serious violent felonies, certain sex offenses, and other categories are ineligible under current law. But for many people with older or lower-level convictions in Bay County, Clean Slate may offer a path to clearing their record and removing the public stigma of a past arrest or conviction.
More Ways to Find Bay County Records
The Michigan Legislature website at legislature.mi.gov has all relevant Michigan statutes for free, including the FOIA law, ICHAT law, sex offender registry statute, and Clean Slate provisions. Read these directly if you need to understand what the law says about records access and your rights.
Third-party aggregators like michigan.staterecords.org compile data from Michigan public sources. They can be a useful first look. But for important decisions, verify through official channels: ICHAT, the court case search, the sheriff, or the MSP FOIA portal. Official sources are always more reliable than aggregators for current and accurate data.
