Union Gap, Washington, in Yakima County, has about 6,600 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.

Booking: Where People Arrested in Union Gap Are Held
The county jail is where a person arrested in Union Gap 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.
