Finding Someone in Custody in Madera County
A person kept in custody after an arrest in Madera County is held at the county jail, run by the Madera County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Madera County Sheriff's Office at inmatepublicview.maderacounty.com (page title: Inmate Inquiry | Search), which answered when SearchSystems opened it on September 23, 2026.
That page is the office's jail information page rather than a roster.

The FBI's agency list also places these agencies in Madera County: Union Pacific Railroad in Madera County (other agency); the Highway Patrol's Madera and Oakhurst Area Offices (state police).
The largest arrest counts reported to the FBI were Madera's 2,339 for 2025, the Madera County Sheriff's Office's 1,186 for 2025 and Chowchilla's 888 for 2025.

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.
