Every one of Michigan's 83 counties elects its own sheriff, and that fact shapes law enforcement from Detroit to the Keweenaw Peninsula. This page covers sheriff's offices and county jails across the state, from the Wayne County Sheriff's Office on Saint Antoine Street in Detroit to the Baraga County Sheriff's Office in L'Anse. Some are large agencies with specialized units. Others are small teams covering thousands of acres of forest and lakeshore. Knowing which kind of office serves your address helps you reach the right people quickly, whether you need a records copy, a fingerprint card, or news about someone in jail.

How a Sheriff's Office Is Organized in Michigan

The sheriff is a constitutional county officer in Michigan. The state constitution of 1963 creates the office, and voters in each county elect a sheriff to a four-year term. The county board of commissioners sets the budget, but the sheriff decides how deputies are deployed and how the jail is run. That split explains why two neighboring counties can offer quite different services.

Duties differ by county, but most Michigan sheriff's offices handle the same core work:

The Michigan State Police is a separate state agency. Troopers work out of posts around the state, and the department maintains the Michigan Public Sex Offender Registry, the statewide criminal history system, and a forensic science division. State police do not supervise sheriffs. They assist on major cases and patrol alongside deputies, especially in sparsely populated counties. The Michigan Commission on Law Enforcement Standards, known as MCOLES, sets the training and licensing standards that road patrol deputies must meet. The Michigan Sheriffs' Association, a statewide professional group, supports elected sheriffs with training and policy work.

Many rural counties also rely on state Secondary Road Patrol grants, created by Public Act 416 of 1978. The money helps pay for deputies who patrol county roads and respond to traffic crashes, which matters in counties with small tax bases.

Sheriff Services in Michigan's Metro Counties and Rural North

In southeast Michigan the sheriff's offices are large and specialized. The Wayne County Sheriff's Office at 1231 Saint Antoine in Detroit (313-224-2222) works in a county where Detroit has its own police department, so its work centers on the jail, court-related duties, and county-level services rather than routine neighborhood patrol. In Pontiac, the Oakland County Sheriff's Office and Oakland County Jail at 1201 Telegraph Road (248-858-4950) serve a county where many cities and townships contract with the sheriff for local policing. If you live in one of those communities, the deputy who answers your call may wear a sheriff's patch even though city hall handles everything else.

Washtenaw County has more listings in our database than any other county. The main sheriff's office and jail are at 2201 Hogback Road in Ann Arbor (734-971-8400). A second station at 7200 South Huron River Drive in Ypsilanti (734-484-6740) serves the eastern side of the county. You can browse the full set on our Washtenaw County page, and compare it with the offices on the Wayne County page.

Go north and the picture changes. The Kalkaska County sheriff's department and jail share an address at 605 North Birch Street in Kalkaska (231-258-8686); see the Kalkaska County listings for details. In the Upper Peninsula, the Iron County Sheriff's Office in Crystal Falls (906-875-0650) and the Baraga County Sheriff's Office in L'Anse (906-524-6177) cover large, forested counties with small populations. Deputies there may drive long distances between calls, and winter weather affects response times. Snowmobile, off-road vehicle, and boating complaints make up a bigger share of the work than they do in the cities. Along Lake Michigan, offices such as the Muskegon County Sheriff's Office at 25 West Walton Avenue (231-724-6351) are more likely to handle marine and beach-related calls.

Between those extremes sit mid-sized counties. In Monroe County, the sheriff's inmate dormitory facility is at 7000 East Dunbar Road (734-240-8001). In Lenawee County, the sheriff's office is at 405 North Winter Street in Adrian (517-263-0524).

Everyday Reasons to Contact a Michigan Sheriff's Office

Jail questions. County jails hold people awaiting trial and people serving short sentences, generally up to a year. State prisons are different. The Michigan Department of Corrections runs them. To find someone in a county jail, call the jail's number or check the county's online roster if it has one. Visiting hours, deposit rules, and mail policies are set by each jail, so ask before you go. For someone in state prison, use the department's Offender Tracking Information System, known as OTIS.

Concealed pistol licenses. In Michigan the county clerk accepts and issues concealed pistol licenses, not the sheriff. You still need fingerprints, and many sheriff's offices and police departments take them. Call first to confirm they offer the service, whether you need an appointment, and what they charge.

Sex offender registration. Michigan's Sex Offenders Registration Act requires registrants to report in person to a local law enforcement agency, the sheriff's office, or a state police post in the area where they live. Confirm the hours and procedure by phone before you go.

Reports and public records. Michigan's Freedom of Information Act lets anyone request public records in writing. A public body generally must respond within five business days and may extend that once by up to ten business days. Send your request to the sheriff's FOIA coordinator and include dates, locations, and any case number. Records tied to an open investigation or a person's privacy may be withheld or redacted.

Civil papers. Deputies serve summonses, subpoenas, and some court orders. If a deputy hands you papers, read the deadlines right away and contact the court that issued them. The sheriff's office cannot give legal advice.

Finding the Right Michigan Sheriff Before You Visit

Jurisdiction follows county lines, and your mailing city may not match your county. Ypsilanti and Ann Arbor are both in Washtenaw County. Pontiac is the seat of Oakland County, and Cassopolis is the seat of Cass County. Most sheriff's offices and jails sit in the county seat, such as Allegan, Alpena, Bad Axe in Huron County, Big Rapids in Mecosta County, and Cadillac in Wexford County.

Read each listing carefully. The Newaygo County entry in White Cloud shows PO Box 845, which is a mailing address, so call 231-689-6623 before heading there. The Calhoun County Sheriff's Office entry at 161 East Michigan Avenue in Battle Creek has no phone number in our database, so check the county's official website before you travel.

If you live inside a city with its own police department, call that department for most incidents. The sheriff still runs the county jail and court security. In townships without a police force, the sheriff is usually the first responder, backed by Michigan State Police troopers. Call 911 for emergencies and use the office's listed non-emergency line for everything else.

When you go in person, bring a government photo ID, any case or citation number, and the names, dates, and addresses relevant to your request. Call ahead for hours, since records counters and fingerprint services often run on different schedules than the jail lobby.

Sheriff offices in Michigan are independently elected county agencies responsible for law enforcement, jail operations, and civil process service. Each county in Michigan elects its own sheriff, who serves as the chief law enforcement officer for that county's unincorporated areas.

Sheriff locations are available in 94 cities across Michigan. They are spread across 83 counties.

Cities with the highest concentration of sheriff office listings include Kalkaska, Pontiac, White Cloud, reflecting the population centers where multiple sub-offices or specialty divisions may be located.

Michigan residents should note that sheriff offices handle civil law enforcement functions — such as serving eviction notices and foreclosure papers — in addition to criminal law enforcement, so the sheriff office is often the correct point of contact for civil legal matters at the county level.

Where Michigan's Sheriff Offices Are Found, Region by Region

Michigan's sheriff offices follow the map of the state's 83 counties, so it helps to think in regions. In the Upper Peninsula, the Iron County Sheriff's Office in Crystal Falls (906-875-0650), the Baraga County Sheriff's Office in L'Anse (906-524-6177), and the Gogebic County Sheriff's Department at 100 West Iron Street in Bessemer (906-667-0203) each serve wide, lightly populated areas.

In the northern Lower Peninsula, the main contacts include the Alpena County Sheriff's Department at 320 Johnson Street (989-354-9836), the Montmorency County Sheriff's Office in Atlanta (989-785-4238), the Antrim County office in Bellaire (231-533-8627), and the Benzie County office in Beulah (231-882-4484). Central and west-central listings include Mecosta County in Big Rapids (231-592-0150), Wexford County in Cadillac (231-779-9211), and Lake County in Baldwin (231-745-2712).

In the southwest, the Cass County Sheriff's Office at 321 Michigan 62 in Cassopolis (269-445-1201) and the Berrien County Sheriff's Department at 2100 East Empire Avenue in Benton Harbor (269-983-7141) serve the area near the Indiana line. Several listings cover both an office and a jail under one name, so ask which entrance to use. Phone numbers and hours can change, so confirm before you travel.

Sheriff Questions Michigan Residents Ask

Michigan sheriffs are elected by the voters of their county to four-year terms, and the office is established by the state constitution. Candidates appear on the November ballot after a primary. Once in office, the sheriff appoints an undersheriff and hires deputies and jail staff. The county board of commissioners approves the budget but does not direct daily operations. If you have a complaint about a deputy, start with the sheriff's office itself, and remember that the sheriff answers to voters at the next election.

A county jail is run by the sheriff and holds people arrested and awaiting court dates, plus people serving shorter sentences, generally up to a year. State prisons are run by the Michigan Department of Corrections and house people serving longer felony sentences. The rules also differ. Each sheriff sets visiting, mail, and commissary policies for the jail, so what works in Kalkaska may not work in Wayne County. For a state prisoner, search the department's OTIS database. For a county inmate, call the jail directly.

Apply through your county clerk's office, not the sheriff. Applicants must be at least 21, complete an approved pistol safety training course that includes range time, and submit fingerprints. Many sheriff's offices and local police departments can take the fingerprints, though not all do, and some require appointments. Call the office on your listing before you go and ask about the cost and accepted payment methods. The Michigan State Police processes the background check, so allow time for it to finish before expecting your license.

For an emergency, call 911 and let the dispatcher decide who responds. For non-emergencies, start local. If you live inside a city with its own police department, call that department. If you live in a township or unincorporated area, call the county sheriff. State police troopers patrol highways and assist sheriffs, but they are not your first call for neighborhood issues like noise, theft, or a civil matter. The state police do run the Michigan Public Sex Offender Registry and handle statewide records, so contact them for those.

Send a written request under the Michigan Freedom of Information Act to the office's FOIA coordinator. Give the date, location, people involved, and a case number if you have one. The office generally must respond within five business days and may extend once by up to ten more business days. Some offices accept requests by email or online form, while others want mail or an in-person visit, so call the number on your listing. Reports tied to open cases or private details may be partly withheld.

Larger counties often run more than one facility. Washtenaw County lists its main office and jail on Hogback Road in Ann Arbor and a separate station on South Huron River Drive in Ypsilanti. Monroe County lists an inmate dormitory facility on East Dunbar Road in addition to its sheriff's office. Kalkaska County has three listings. Check the address and phone number on each entry before you visit, because the records counter, the jail, and a substation may be in different buildings with different hours.
