Butte County Inmate Release Date
A projected release date is a calculated or eligibility-based date. An actual release date is the date and time the custody event ended. Butte County research has one especially important local rule: the jail handbook says time computation is completed after a person is completely sentenced on all cases, a release-date notification is sent, and the computation can take one to four weeks depending on sentence type. That means a release date may not exist at booking, arraignment, or even after one case is sentenced if other cases remain unresolved.
Scheduled vs actual release. A jail sentence date, a court release order, a CDCR eligibility date, and a VINE release alert can describe related but different points in the release process.
For a Butte County Jail sentence, the release date is local sentence computation. For a CDCR sentence, California uses date fields such as EPRD, MEPD, NPED, YPED, and EPED. For a federal sentence, BOP is the public release-date source. For immigration custody, ICE ODLS is only relevant when the person entered ICE custody.
Find a Butte Release Date
Start by identifying where the person is held and why. A Butte County Jail booking for a local case is not the same as CDCR custody. A person may also leave the jail by transfer, not by release to the community. The correct lookup path changes when the record shows another county warrant, a parole hold, PRCS, a prison sentence, federal custody, or immigration custody.
- Use the BCSO weekly booking logs to identify the booking date, inmate number, arresting or holding agency, case type, bail, charges, and status language.
- Check Butte Superior Court for sentencing, bail, own-recognizance release, dismissal, warrant recall, probation, prison commitment, or another court order.
- For a sentenced Butte County Jail case, use the jail records or release-date computation process rather than CDCR CIRIS.
- For a CDCR case, search CIRIS and check BPH date fields or hearing results where applicable.
- For state parole or PRCS after release, use CDCR DAPO, the Chico parole unit, or Butte County Probation, depending on the supervision type.
- For a current custody-status change, register for California VINE through the VINELink Release Check.
- When online records do not show the date, request the booking/release record from the Sheriff's Records Office or a CDCR public record for state-prison releases.
For a broader named-person lookup across county, state, court, federal, and records-request channels, start with Butte County released inmates.
Butte Jail Computation Rules
Section 19's release-date computation angle should lead this page because it is more useful than a generic roster instruction. Butte's jail handbook says time computation occurs after complete sentencing on all cases. The handbook also tells incarcerated people not to request a release date unless they have not received notification within the one-to-four-week computation period. Multiple cases, pending sentencing, holds, warrants, or detainers can prevent a simple date from being final.
The handbook separately says scheduled releases normally occur between 8:00 a.m. and 10:00 a.m. on the final day of incarceration if the sentence is served and no holds remain. Court releases work differently. If release follows a court appearance, the jail must process release papers and confirm no holds; the handbook says that can take up to eight hours. A court record may therefore show release before the person has physically left Butte County Jail.
A Butte County Jail release date is computed locally from the sentence, credits, all cases, discipline, and holds.
Good-Time Credit in California
County jail credits and state prison credits use different California rules. Penal Code section 4019 covers many county jail and local custody settings, including pre-sentence custody, county jail sentences, probation-condition custody, contempt, parole or PRCS custodial sanctions, and Penal Code section 1170(h) local sentences. It is technical and has exceptions, so the practical Butte County explanation is careful: local jail sentences may be reduced by statutory credits, but the jail computes the actual date from the court sentence and the person's full custody record.
For state prison, Penal Code section 2933 covers worktime credits, and section 2933.05 covers approved rehabilitative programming credits. Penal Code section 2933.1 limits people convicted of violent felonies listed in section 667.5(c) to no more than 15 percent worktime credit, which is the common reason people ask about serving about 85 percent. Proposition 57 created nonviolent parole consideration after completion of the full term for the primary offense and authorized CDCR to award credits for good behavior and approved rehabilitative or educational achievement.
Those state-prison rules do not calculate a Butte County Jail release date. They matter when the person has been transferred to CDCR, is in a CDCR pre-release setting, or is being released to parole or PRCS after a state term.
CDCR Release Date Fields
California's public CDCR search entry point is CIRIS at ciris.mt.cdcr.ca.gov. CA.gov describes CIRIS results as including name, CDCR number, age, current location, commitment counties, admission date, and Board of Parole Hearing dates and outcomes for people currently in CDCR custody. That current-custody focus is important. CIRIS is useful for a current state prisoner, but it is not a complete released-inmate archive for every former California prisoner.
| California field | What it means |
|---|---|
| EPRD | Earliest Possible Release Date for a determinate sentence after applicable credits. |
| MEPD | Minimum Eligible Parole Date for an indeterminate or life sentence. |
| NPED | Nonviolent Parole Eligible Date under Proposition 57 nonviolent parole consideration. |
| YPED | Youth Parole Eligible Date for eligible youth offender parole review. |
| EPED | Elderly Parole Eligible Date for eligible elderly parole review. |
Why Butte Release Dates Change
A release date changes when the legal or custody facts change. Butte's weekly booking logs can show case type, bail, charges, holds, warrants, parole or PRCS clues, and status language, but the date calculation depends on later court and custody events. If a person is sentenced on one case and still held on another, the first case's end date does not decide release. If a release order exists but a detainer remains, the person may be transferred rather than released to the community.
| Change factor | How it affects the date |
|---|---|
| All cases not fully sentenced | The Butte jail computation may wait until every case is completely sentenced. |
| Holds, warrants, or detainers | The person may remain in custody or be transferred after the local case ends. |
| Jail credits and discipline | Local conduct or work credits can affect the computed release date, subject to law and jail calculation. |
| Court orders | Bail, own-recognizance release, dismissal, resentencing, or warrant recall can change the path. |
| CDCR credits or BPH action | State-prison release and parole eligibility may shift through CDCR credit rules or Board action. |
| Transfer to another system | BOP, ICE, another county, or CDCR may become the source for later release information. |
Pretrial Butte Release Timing
A pretrial detainee usually does not have a projected release date in the same sense as a sentenced inmate. Release may depend on bail, own-recognizance terms, a court order, prosecutor action, dismissal, warrant status, or a hold from another agency. The BCSO booking log may show bail and case type, but it is not a release-date calculator. Butte Superior Court is the stronger source for hearings and orders, and VINE is the stronger source for a custody-status change.
If a court orders release, do not treat that as immediate door release. Butte's handbook says court-release processing can take up to eight hours after papers are processed if no holds remain. If a hold exists, release from one case can still leave the person in custody. This is why the court portal, jail records, and VINE should be reconciled before telling someone that a person is out.
Parole and PRCS Date Paths
After a CDCR release, supervision can affect where the next record appears. State parole is handled by CDCR's Division of Adult Parole Operations, with the Chico parole unit serving the Butte County area. PRCS is handled locally by Butte County Probation because CDCR says PRCS is county supervision after release from CDCR and the person is discharged from CDCR jurisdiction. That difference matters when a family member sees a prison release date but still needs to know who supervises the person in Butte County.
BPH hearing results can also be mistaken for release dates. A grant means the person was found suitable and recommended for release to parole, but BPH decisions can be reviewed by the legal division, the full Board, and, for certain decisions, the Governor. Some grants may become final within 120 days, and some have an additional 30-day Governor review period. Use BPH results to understand the parole path, then confirm actual CDCR release and supervision separately.
Confirm Butte Release Dates
Use the most direct source for the custody type. For Butte County Jail, use the Sheriff's Records Office, jail release-date computation, VINE, and Butte Superior Court. The Sheriff's Records Office maintains bookings into the jail and can be the records-request path for release date, release time, and manner of release. For the court reason, use the Butte court portal or criminal division. For a CDCR prisoner, use CIRIS while current, BPH materials when relevant, DAPO parole, PRCS through Butte Probation, or CDCR public records.
Federal and immigration systems are separate. BOP records from 1982 onward can show federal release dates, and BOP explains that a past date with no facility location generally indicates release from BOP custody. ICE ODLS is relevant only if immigration custody is involved, and it may show current custody or a recent release within a limited window. None of those systems is a Butte County Jail release-date calculator, but each can explain why a person no longer appears in local custody.
