Rancho Santa Margarita, California, in Orange County, has about 46,000 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 Superior Court of California, County of Orange. 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 Rancho Santa Margarita
The FBI lists Rancho Santa Margarita with an arrest reporting agency of its own, filed as Rancho Santa Margarita Police Department. It reported 404 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 Orange County Sheriff's Office is the county agency. It reported 1,884 arrests for 2025.
The FBI's agency list also places these agencies in Orange County: the University of California at Irvine, California State University at Fullerton and Irvine Valley College (campus police); Union Pacific Railroad in Orange County (other); California State Parks at Orange Coast (state agency); the Highway Patrol's Westminster, Santa Ana and Capistrano Area Offices (state police).

Booking: Where People Arrested in Rancho Santa Margarita Are Held
A person kept in custody after an arrest in Rancho Santa Margarita is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2025 the jail held about 3,930 people, down from about 5,650 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 5,093 beds, and it ran at 67 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Orange County Sheriff's Office at ocsheriff.gov/how-do-i/get-inmate-information (page title: Get Inmate Information... | Orange County California | Sheriff's Department), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A person sentenced to prison serves the sentence in a facility of the California Department of Corrections and Rehabilitation, whose inmate locator is at cdcr.ca.gov/search.
How to Find Out About an Arrest in Rancho Santa Margarita
Whether someone was arrested in Rancho Santa Margarita, and what came of it, shows up in three places: the custody page of the Orange County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Superior Court of California, County of Orange, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at occourts.org/online-services/case-access); the District Attorney, which decides whether an arrest becomes a charge (its page is at ocdistrictattorney.gov).
California does not let the public search another person's statewide criminal history. The record kept by the California Department of Justice goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
Getting a Copy of an Arrest Record in Rancho Santa Margarita
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 California Public Records Act the agency must answer within 10 days, with up to 14 more days in unusual circumstances, and it may charge the direct cost of copying only, not staff time.
