Access Washtenaw County Police Blotter

Washtenaw County police blotter records cover law enforcement activity across this major southeast Michigan county, including University of Michigan-related calls in Ann Arbor, township incidents throughout the county, and cases handled by the Washtenaw County Sheriff's Office at its Hogback Road headquarters. Michigan's Freedom of Information Act gives any person the right to request these public records, and this page covers how the system works, what records are available, and where to search online before filing a formal request.

Washtenaw County Sheriff's Office

Washtenaw County is one of Michigan's larger and more populous counties, anchored by Ann Arbor and the University of Michigan. The Sheriff's Office serves the townships and unincorporated areas of the county, while the Ann Arbor Police Department operates separately within the city. If an incident happened inside Ann Arbor city limits, AAPD holds those records. The Sheriff covers the surrounding townships, county roads, and smaller communities like Ypsilanti Township and the townships surrounding it.

One important distinction in Washtenaw County: the city of Ypsilanti has its own police department, as do Saline, Milan, Chelsea, and other communities. For incidents in those cities, contact the relevant city department. The Sheriff's records cover what happens outside those city jurisdictions. Knowing which agency responded saves time when you are preparing a FOIA request.

The Sheriff's Office provides an online inmate lookup on the county website, letting you check current jail status and charges without a formal request. The county's extensive online resources also include court information and other public databases that can help before you go the FOIA route.

Washtenaw County also benefits from the proximity of the University of Michigan campus, which has its own Division of Public Safety. UMPD records are separate from both the Sheriff and the Ann Arbor Police Department. If an incident happened on campus, UMPD is the right contact.

Filing a FOIA Request with Washtenaw County

To request Washtenaw County Sheriff's Office police blotter records, submit a written FOIA request to 2201 Hogback Road, Ann Arbor, MI 48105, or use the county's preferred submission method, which you can confirm by calling (734) 971-3911 or checking the Sheriff's website. The request must be in writing under Michigan law.

Describe your request clearly. Include the incident date or date range, names of parties involved, case numbers if available, and the type of record you are requesting. Washtenaw County handles a large volume of requests given its size, so being specific helps the records staff locate the right material without a back-and-forth clarification process.

Michigan's FOIA, starting at MCL 15.231, gives any person the right to inspect or receive copies of public records held by public bodies. You do not need to be a Michigan or Washtenaw County resident. You do not need to explain why you want the records. The law does not require any justification.

The office must respond within five business days under MCL 15.235. For complex or high-volume requests, they may extend by up to ten additional business days with written notice. The response will grant access, partially grant it with redactions and explanations, or deny the request citing the applicable exemption under MCL 15.243.

Fees are set by MCL 15.234. The agency charges actual labor costs using the rate of the lowest-paid employee who can fulfill the request, plus copying or media costs. If the estimate exceeds $50, a deposit of up to 50% may be required. Indigent individuals can request a waiver on the first $20 of fees.

What Washtenaw County Police Blotter Records Include

The police blotter is a daily log of law enforcement calls and responses. In Washtenaw County, this covers everything the Sheriff's deputies handle: traffic crashes, property crimes, domestic calls, drug arrests, assaults, and the wide range of incidents that come with a county of nearly 370,000 people adjacent to a major university.

Arrest records include the person's name, date of birth, arrest date and time, charges filed, and booking information. Mugshots may be available. Bond amounts, charges entered into the court system, and current jail status often appear in the record. Home addresses are frequently redacted under privacy provisions, particularly for domestic cases.

Full incident reports are more detailed and require a formal FOIA request. They include officer narratives, witness information, and scene descriptions. If a case is active, portions may be withheld. Juvenile records are not public in Michigan. Any incidents involving minors will have that information removed before the agency releases the record.

Records from Ann Arbor PD, Ypsilanti PD, Saline PD, and other city departments in Washtenaw County are held separately by those agencies. The Sheriff covers unincorporated townships and county roads. Large-volume records users often find it helpful to call (734) 971-3911 first to confirm which agency has what they are looking for.

Michigan FOIA Law and Denial Appeals

The Michigan Freedom of Information Act, beginning at MCL 15.231, presumes public records are open unless a specific exemption applies. The Washtenaw County Sheriff's Office must justify any denial. Common exemptions relevant to blotter requests are in MCL 15.243 and include active investigation materials, victim personal information, and law enforcement techniques whose disclosure could harm public safety.

If your request is denied, the agency must explain which exemption applies and why. You have 180 days to appeal to the agency head. If that internal appeal fails, you can seek review in Washtenaw County Circuit Court under MCL 15.240. Courts can order disclosure and award attorney fees if the agency improperly withheld records.
