Adult Probation Services

Summary of Services



The Adult Division of the Probation Department is an integral partner in the County’s criminal justice system and contributes to the enhancement of public safety through Court services and investigations, and through supervision and treatment of adult offenders.  The Probation Department supervises approximately 2,000 adult offenders on court-ordered grants of probation, diversion programs such as Prop 36, Drug Court, Pre-Trial Diversion (formerly known as Deferred Entry of Judgment), and Post-Release Community Supervision (PRCS).

The Adult Division operates out of the department's main office located at 465 S. Washington Street in downtown Sonora. This division provides investigations, pre-trial services, adult probation supervision, as well as programs that serve as alternatives to detention, including work release, community service, and electronic monitoring.

The Probation department also operates an adult Day Reporting Center, located at 101 Hospital Road.  Services at the Day Reporting Center are provided by GEO Reentry Services (formerly known as Behavioral Interventions, Inc.). The company offers evidence based rehabilitative programs designed to facilitate the successful reintegration of adult offenders into the community, while maintaining public safety.

Annual Report on the Implementation of Community Corrections Partnership Plans


Since the passage of Assembly Bill 109 (AB 109) criminal justice officials and stakeholders in California’s fifty-eight counties have been engaged in innovative, productive and challenging conversations to set priorities that balance concerns over local public safety with alternatives to custody that stem cycles of crime. These counties’ Community Corrections Partnerships (CCPs) were also tasked with planning for the development and/or enhancement of programming and treatment for offenders with co-occurring mental health needs. Annual reports on the implementation of CCP plans are available on the California Board of State and Community Corrections (BSCC) Realignment webpage.
