Grafton, Wisconsin, in Ozaukee County, has about 13,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Ozaukee County Circuit Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Grafton
The FBI lists Grafton with an arrest reporting agency of its own, filed as Grafton Police Department. It reported 176 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Ozaukee County Sheriff's Office is the county agency. It reported 572 arrests for 2025.
How Many Arrests Grafton Reports
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Grafton: 176 for 2025, 182 for 2024, 192 for 2023, 244 for 2022, 241 for 2021 and 419 for 2020.
Grafton's 176 arrests in 2025 were down 3.3 percent from 182 in 2024.
Through April 2026, Grafton reported 63 arrests, against 63 in the same months of 2025.
Across Ozaukee County, the seven agencies with all twelve months of 2025 on file reported 1,634 arrests between them.
Booking: Where People Arrested in Grafton Are Held
The county jail is where a person arrested in Grafton and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2025 the jail held about 210 people, up from about 200 in 2019. Its rated capacity in 2025 was 262 beds, and it ran at 79 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Grafton
An arrest in Grafton can be traced in two places, depending on where the case stands: the case index of the Ozaukee County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at ozaukeecounty.gov/190/Access-Court-Records); the District Attorney, which decides whether an arrest becomes a charge (its page is at ozaukeecounty.gov/137/District-Attorney, phone 262-284-8380).
Statewide, Wisconsin Circuit Court Access is the free statewide case search of every circuit court.
Wisconsin is one of the states that lets anyone look up another person's statewide criminal history: the Wisconsin Online Record Check System lets anyone run a name-based check, through the Wisconsin Department of Justice. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Grafton
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Wisconsin Public Records Law the agency must answer as soon as practicable and without delay; the law sets no number of days, and it may charge the actual cost of copying and locating, with no charge for the first $50 of locating.
