What Is Inmate Records In Marin County?

Inmate records in Marin County are official government documents maintained by the Marin County Sheriff's Office that contain comprehensive information about individuals who are currently or were previously incarcerated within the county's correctional facilities. Pursuant to California Government Code § 6254(f), these records document the custody status, charges, and other pertinent information regarding persons held in county detention facilities.

Inmate records are distinct from court records in several important aspects. While the Marin County Superior Court maintains case files documenting legal proceedings, charges, and court appearances, the Marin County Sheriff's Office maintains custody records that track an individual's status within the correctional system. Court records focus on the judicial process, whereas inmate records document the physical custody and management of incarcerated individuals.

The creation of inmate records follows a standardized process:

• Initial creation occurs during booking/intake when an individual is first taken into custody
• Records are continuously updated throughout the period of incarceration
• Documentation includes housing assignments, disciplinary actions, and program participation
• Records are finalized upon release but maintained according to California Penal Code § 832.5

The California Department of Corrections and Rehabilitation defines inmate records as "documents containing information about an individual in custody, including personal identification, criminal history, custody classification, and release information." These records serve multiple purposes, including ensuring proper identification, facilitating appropriate housing assignments, and maintaining public safety.

Marin County Prison System

The Marin County correctional system operates under the jurisdiction of the Marin County Sheriff's Office, which maintains responsibility for the detention and custody of individuals arrested within the county. The system primarily consists of the Marin County Jail, which houses both pre-trial detainees and individuals serving sentences of up to one year as prescribed by California law.

It is important to distinguish between the county jail system and the state prison system. The Marin County Jail houses individuals who:

• Are awaiting trial or court proceedings
• Have been sentenced to terms of one year or less
• Are being held temporarily while awaiting transfer to state facilities
• Have violated probation or parole conditions

In contrast, the California Department of Corrections and Rehabilitation operates state prisons that house individuals convicted of felonies and sentenced to terms exceeding one year. Individuals convicted in Marin County courts of serious felonies are typically transferred to state custody after sentencing.

The Marin County Sheriff's Office Custody Division oversees all jail operations, including intake, housing, transportation, and release of inmates. For information regarding individuals in custody, members of the public may contact:
