San Mateo County Released Inmates
A release record answers a different question from a live jail roster. The roster asks whether a person is in custody right now. A San Mateo County release record asks what happened to the booking, sentence, transfer, court order, or custody term. For a person booked into Maguire Correctional Facility or Maple Street Correctional Center, the county's public locator is most useful before the release is complete. After the person leaves, local confirmation shifts to the San Mateo County Sheriff's Criminal Records Bureau, the court case, California VINE, probation or parole, and any receiving agency.
Release does not always mean a case is over. A person may leave the jail on bail, own-recognizance release, time served, dismissal, sentence completion, alternative custody, transfer to CDCR, transfer to another agency, or a court order. San Mateo County is especially release-adjacent because the Sheriff's Corrections Division also identifies work furlough, electronic monitoring, the Sheriff's Work Program, and transitional housing. A person can be out of a locked jail bed and still owe a court-ordered custody or supervision term.
San Mateo County Release Paths
The right place to verify San Mateo County released inmates depends on the path out of custody. Maguire is the main jail, Maple Street is both a jail and transitional center, and the Alternative Sentencing Bureau handles local custody alternatives. CDCR, BOP, ICE, and the court each become relevant only when that agency has the next part of the record.
| Release path | What it means | Where to check next |
|---|---|---|
| Bail or own recognizance | The person left county jail under changed court custody terms. | San Mateo Superior Court, jail records, VINE history. |
| Time served or sentence complete | The local jail term ended after credits and court orders were applied. | Sheriff's booking chronology, court minutes, probation if ordered. |
| Alternative sentencing | The person may serve through work program, work furlough, or electronic monitoring. | Alternative Sentencing Bureau, court order, booking chronology. |
| Transfer to CDCR | A San Mateo case became a state-prison commitment. | CDCR CIRIS, BPH, DAPO, court record. |
| Federal or immigration custody | The county booking ended, but another authority may hold the person. | BOP locator, ICE ODLS, sheriff detainer and warrant policy. |
Note: A missing jail-locator result can mean release, transfer, delay, name mismatch, sealed data, or search error.
San Mateo County Release Records
The San Mateo County Sheriff's Criminal Records Bureau is the key local office for a jail-release record after custody ends. The sheriff describes the bureau as the Custodian of Records, the repository for county criminal records, and the official criminal record keeper for the Sheriff's Office and the communities it serves. Its local term matters: a person with a Sheriff's Office criminal record may request a booking chronology showing time spent in the San Mateo County Jail and/or the Sheriff's Work Program. That phrase is often more useful than a generic request for an inmate release record.
| Field | What it may show |
|---|---|
| Name and birth date | Identity markers used to distinguish people with similar names. |
| Booking or case number | The local booking, agency, or court tie-back for the custody event. |
| Facility | Maguire, Maple Street, Sheriff's Work Program, or another listed custody point. |
| Booking and release dates | When jail custody started and when the county custody event ended. |
| Release reason | Bail, time served, court order, transfer, dismissal, program placement, or other disposition when public. |
| Supervision or transfer | Probation, PRCS, parole, CDCR, another county, BOP, ICE, or other follow-up channel. |
Not every field is public. California law can limit investigatory, juvenile, sealed, protected, victim, medical, or safety-sensitive information. A field that is missing online is not proof that no release occurred. It may only mean the detail is not displayed in the public view.
Get San Mateo County Release Records
The county records path begins with the Sheriff's Criminal Records Bureau. The bureau page directs report requests and booking chronology requests to sheriffs_recordsrequest@smcgov.org and lists 650-363-4525 for records questions. The sheriff's public records page also provides a Public Records Act webform, while its instructions distinguish a person's own records and attorney requests from general public-records requests.
- Identify the person by full name, date of birth if known, booking date, case number, or booking number.
- Ask for a booking chronology showing San Mateo County Jail or Sheriff's Work Program custody dates and release or disposition information.
- Use the release-of-information process when requesting your own record or when an attorney represents an involved party.
- Use the Public Records Act webform for a general public-record request, with a date range and a clear description.
- Cross-check the response against the San Mateo Superior Court case record if the release depends on a court order.

The San Mateo County release-record request should stay precise. "Booking chronology for [name] showing San Mateo County Jail or Sheriff's Work Program custody dates and release or disposition information" matches the local records term and gives the custodian a clear target.
California Release Record Rules
California's Public Records Act is now codified at Government Code section 7920.000 and following, and the official code portal is the California Legislature site. Jail and release records may be public in part, but law-enforcement agencies can withhold material that falls within investigatory, safety, juvenile, sealed, victim, or other protected categories. Arrest relief and clean-record rules can also change what is available after a case ends.
For San Mateo County released inmates, court relief matters because the jail booking, the court case, and later public access may not move at the same pace. Penal Code sections 851.91 and 851.92 address petition-based sealing for arrests not resulting in conviction, section 851.93 addresses automatic arrest relief, and sections 1203.4 and 1203.425 address conviction relief or Clean Slate relief. A sealed or restricted record may still exist at the originating office even when it is not displayed online.
Find Released San Mateo County Inmates
A clean San Mateo County released inmate search starts with custody type. The Sheriff's Corrections Division links to the public inmate locator for current county jail custody. The City of San Mateo also points users to the county jail locator for real-time name-based jail information. That locator is not described by the sheriff as a durable released-inmate archive, so a no-result after release should lead to records, court, VINE, and supervision checks.
- Search the San Mateo County Inmate Locator while the person may still be held.
- If the person is gone from the roster, check spelling, aliases, middle names, and date of birth.
- Look for the court case in MIDX or the court's Odyssey access pages.
- Check California VINE for custody-status changes and release notification history.
- Request the Sheriff's booking chronology when online sources do not give a final release answer.
- Use CDCR, BOP, or ICE only when the person's case moved to that custody system.
A released person usually drops off the current jail locator. Treat that as a clue, then confirm through a positive record.
The county's release-list intent is handled in more detail on the 24-Hour Release List, but San Mateo does not publish a rolling public release log in the research sources. For one named person, the home search path is stronger than a feed search because it follows the booking, case, custody, and supervision records together.
San Mateo County Search Channels
The sheriff's corrections page is the local starting point because it identifies the jail facilities and links to the county inmate locator. The screenshot below comes from the San Mateo County Sheriff's Corrections Division page, which is the controlling local source for Maguire, Maple Street, transitional housing, and the Alternative Sentencing Bureau.
Use that sheriff source for county jail custody, then move to records or court once the person has been released from the live roster.
For a person sentenced from San Mateo County to state prison, the county jail record is no longer the main public tracking system. The relevant state source is CDCR CIRIS, shown below in the captured search entry point.
CIRIS is for California state-prison custody and related public fields, not for a simple Maguire bond release.
CDCR Search for San Mateo Releases
CDCR matters when a San Mateo Superior Court case becomes a state-prison commitment or when a released state-prison person is supervised in the county. California's public locator is CIRIS, the California Incarcerated Records and Information Search. CA.gov describes public fields for people currently in CDCR custody, including name, CDCR number, age, current location, commitment counties, admission date, and Board of Parole Hearing dates and outcomes. CDCR public descriptions also mention parole eligible date by month and year where applicable.
| CIRIS field | How it helps a San Mateo release lookup |
|---|---|
| CDCR number | Confirms the person is in the state-prison system, not just county jail. |
| Current location | Shows whether CDCR custody is active at the time of search. |
| Commitment county | Can tie a state-prison record back to a San Mateo County case. |
| Admission date | Places the state-prison term after the county jail transfer. |
| Parole eligibility or BPH data | Points to parole-hearing or release-review channels for state cases. |
CIRIS is not a complete public archive of every released CDCR person. If the person has already discharged or moved to parole or PRCS, use DAPO, San Mateo County Probation, BPH results, court records, or CDCR records channels as the next step.
San Mateo Court Release Links
San Mateo Superior Court records often explain why a person left jail. The court's case-access guidance says MIDX lets users search non-confidential and non-sealed cases by case number, party name, or case filing date. It also says criminal cases filed before 1993 should be handled through the Criminal Court Clerk's Office at 650-261-5100 option 1. Older releases may need that clerk path rather than an online-only search.
The court's Odyssey portal information and Criminal Division pages are useful when the jail record gives only a booking clue. Court minutes can show bail changes, dismissal, sentence, probation, warrants, future hearings, and other orders that explain the release. A court result should still be paired with the sheriff's booking chronology when the question is the exact jail custody date.
San Mateo Release Supervision
Post-release supervision in San Mateo County can mean probation, mandatory supervision, PRCS, or state parole. San Mateo County Probation states that it supervises clients on supervised probation, mandatory supervision, and Post Release Community Supervision. CDCR's Division of Adult Parole Operations handles state parole, and the Board of Parole Hearings handles parole suitability for CDCR cases. A county jail release and a CDCR parole release are different records.
- Probation
- Court-ordered supervision often tied to a county criminal case.
- PRCS
- Post Release Community Supervision, a county supervision path after some CDCR releases.
- Parole
- State supervision through CDCR DAPO after a state-prison release.
- Discharge
- The end of a custody or supervision term when the agency closes the status.
San Mateo's local reentry landscape also matters. Research identified Service League of San Mateo County in-custody support and property-release help, while the Sheriff's Corrections Division describes services meant to support life during and after incarceration. These resources do not prove release, but they can explain why a person moves from custody to a support or supervision channel.
San Mateo VINE and Federal Releases
California VINE is the statewide custody-status and notification route, with 1-877-411-5588 listed for California VINE. It can be useful when a participating agency sends custody-change data. VINE does not replace the court judgment or the sheriff's booking chronology, but it can give a custody-status event or alert history that helps confirm a release.
Federal and immigration custody use separate systems. The BOP inmate locator covers federal inmates from 1982 forward, and BOP says a past release date with no facility location means the person is no longer in BOP custody. ICE ODLS is for current ICE detention. San Mateo County adds an important local layer: the sheriff's immigration detainers and warrants page says the County has an ordinance limiting cooperation and that the Sheriff's Office will not hold, detain, house, transfer, or facilitate an arrest unless there is a judicial warrant or another legal requirement.
San Mateo Released vs Custody
San Mateo County released inmates can appear in different systems at different times. Use the system that matches the custody event, not the one that is easiest to find.
| System | Best for | Limit |
|---|---|---|
| County jail locator | Current Maguire or Maple Street custody. | Not a public released-inmate archive. |
| Sheriff booking chronology | Local jail or Sheriff's Work Program custody dates. | Must be requested from records channels. |
| San Mateo Superior Court | Disposition, sentence, bail, warrants, dismissal, probation. | Some records are sealed or require clerk help. |
| CDCR CIRIS | State-prison commitments and public CDCR fields. | Not a county jail release tool. |
| BOP or ICE | Federal sentence or immigration detention. | Does not prove a local jail release unless the case moved there. |
San Mateo Detention Facilities
San Mateo County's release story is local and facility-specific. Maguire is the main jail. Maple Street includes jail housing and transitional housing. The Transitional Housing Unit and Alternative Sentencing Bureau can make a person look released from a traditional jail bed while a court-ordered custody program still exists. Use these facility pages to match the release path to the right office.
