Finding Someone in Custody in Albany
A person kept in custody after an arrest in Albany is held at the county jail, run by the Alameda County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Alameda County Sheriff's Office at acgov.org/sheriff_app (page title: Inmate Locator), which answered when SearchSystems opened it on September 23, 2026.
Someone booked recently shows on that page; someone cited and released at the scene, or held a few hours at a city station, does not.
The Alameda County Jail by the Numbers
On an average day in 2025 the jail held about 1,450 people, down from about 2,530 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 3,485 beds, and it ran at 50 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
Alameda County has about 1.6 million residents (2024 Census Bureau estimate), so the jail holds about 9 people for every 10,000 residents.
Who Books People Into the Alameda County Jail
The Alameda County Sheriff's Office and the agency that reports for Albany (filed by the FBI as Albany Police Department) make the arrests that end in a booking in and around Albany.
The FBI's agency list also places six state police units, three other agencies, one state agency and three campus police departments in Alameda County (the arrest records guide names each one).
The largest arrest counts reported to the FBI were Oakland's 5,383 for 2023, the Alameda County Sheriff's Office's 2,610 for 2025 and Berkeley's 2,111 for 2025.
Together, the 13 agencies in Alameda County with all twelve months of 2025 on file reported 14,194 arrests to the FBI that year. Those kept in custody were booked into the county jail; a person cited and released at the scene was not.
The counts, agency by agency and year by year, are in Albany arrest records.
From the Jail to State Prison
A sentence of more than a year is served in state prison, not the jail; the California Department of Corrections and Rehabilitation lists its inmates at cdcr.ca.gov/search.
