Sunnyside, Washington, in Yakima County, has about 16,000 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 Prosecuting Attorney files charges, a case in the Yakima County Superior 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 Sunnyside
The FBI lists Sunnyside with an arrest reporting agency of its own, filed as Sunnyside Police Department. It reported 580 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 Yakima County Sheriff's Office is the county agency. It reported 567 arrests for 2025.
How Many Arrests Sunnyside Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them 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.
- Sunnyside: 580 for 2025, 793 for 2024, 745 for 2023, 862 for 2022, 848 for 2021 and 758 for 2020.
Sunnyside's 580 arrests in 2025 were down 27 percent from 793 in 2024.
Across Yakima County, the ten agencies with all twelve months of 2025 on file reported 9,323 arrests between them.
Booking: Where People Arrested in Sunnyside Are Held
The county jail is where a person arrested in Sunnyside 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 2024 the jail held about 580 people, down from about 1,080 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 1,069 beds, and it ran at 60 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
