  • Serving sentences of 1 year or less
  • Operated by county Sheriff's Department

AB 109 and California Criminal Justice Realignment

California's 2011 Public Safety Realignment Act (AB 109) fundamentally changed who goes to state prison and who stays in county jail. Understanding this is essential for locating someone in the system.

What AB 109 Changed

Before 2011, most felony convictions meant a sentence to CDCR state prison. AB 109 shifted responsibility for "non-non-non" offenders, non-violent, non-serious, non-sex offense felons, to county jails. These individuals now serve their sentences locally rather than in state prison.

This means someone convicted of certain drug offenses, property crimes, or lower-level felonies may be housed in a county jail for their entire sentence, even if that sentence is several years long. They are called "1170(h)" inmates after the relevant code section.

If you cannot find someone in the CDCR system, they may be serving a felony sentence in county jail under AB 109 rather than being transferred to state prison.

Who Still Goes to State Prison

CDCR receives individuals convicted of: serious felonies (listed in PC 1192.7), violent felonies (listed in PC 667.5), sex offenses requiring registration under PC 290, and anyone with a prior strike conviction. CDCR also receives people whose probation has been revoked from county supervision under Post-Release Community Supervision (PRCS).

Not finding someone in CDCR? Check if they are serving a county felony sentence under AB 109 by searching the county jail inmate roster where they were sentenced. Use our county jail directory to search all 58 counties.

Parole, Supervision, and Reentry Programs

Understanding what happens when someone is released from CDCR is important for families planning for a loved one's return.

📅

CDCR Parole

Most state prison inmates are released on parole, which means supervised release in the community. Parole in California typically lasts 3 years for most felonies, up to 5 years for violent offenses. Parolees are assigned to a parole agent in the county where they plan to live. Parole violations can result in return to prison without a new trial.

🏠

Reentry Housing

CDCR operates Reentry Hubs at various locations statewide and contracts with Residential Multiservice Centers (RMSCs) to provide transitional housing for parolees who have no other housing. Contact the CDCR Division of Adult Parole Operations (DAPO) at (916) 255-2758 to find reentry resources in a specific county.

📈

Projected Release Date

The CDCR inmate locator displays a Minimum Eligible Parole Date (MEPD) or Earliest Possible Release Date (EPRD) for most inmates. These dates can change based on good behavior credits, disciplinary actions, and changes in law. The displayed date is an estimate, confirm the actual release date by calling the facility directly at least 30 days in advance.

California State Prison: Frequently Asked Questions

Use the CDCR Inmate Locator at cdcr.ca.gov/ciris. Search by first name, last name, and CDCR number if you have it. The locator shows current facility, admission date, and projected release date. If the person was recently sentenced they may not appear for several days while in transit from county jail to a reception center.

County jails hold people awaiting trial or serving sentences under one year. State prisons hold people convicted of felonies with sentences over one year. A person stays in county jail until sentencing, then transfers to a CDCR reception center. If you cannot find someone in a county jail roster, it may mean they have already been transferred to state custody and should be searched in the CDCR system instead.

Reception centers are intake facilities where newly sentenced inmates are processed for 60 to 90 days. They receive medical and mental health evaluations, educational assessments, and security classification before being assigned to a permanent facility. California reception centers include CIM Chino for Southern California men, Deuel Vocational Institution for Northern California men, and CCWF Chowchilla for women.

Yes. Submit a Visitor Questionnaire (CDCR Form 106) to the inmate's facility. Approval takes 4 to 6 weeks. Bring valid photo ID to visits. Most CDCR facilities offer both in-person contact visits and video visits. Visiting privileges can be suspended for rule violations. Check cdcr.ca.gov for each facility's specific visiting schedule and rules.

CDCR inmates use the JPay system. Send funds at jpay.com, through the JPay app, or at MoneyGram locations. You need the inmate's CDCR number and full legal name. Processing takes 1 to 3 business days. Trust account funds are used for commissary, phone calls, and approved purchases.

CDCR classifies inmates Levels I through V based on offense severity, criminal history, and other factors. Level I is minimum security camps. Levels II and III are medium security. Level IV is high security. Level V covers the most serious cases. Classification is determined at the reception center after initial intake processing.
