Alternative Custody Status
The Sheriff Custody Services page lists custody alternative alongside the county's detention facilities. The research also cites a 2019 Sheriff fact sheet saying the Custody Services Bureau manages a Custody Alternative Facility supervising an average of 425 clients through electronic home detention, work alternative, county parole, alcohol monitoring, and pretrial release. That makes this page different from Martinez, West County, and Marsh Creek. The person may already be outside a jail cell, but the official status may still be custody, monitoring, or supervision.
For a released-inmates site, this distinction is critical. Many people use the word "released" to mean "not currently in a jail bed." The official record may be more precise: released to electronic monitoring, placed on pretrial release, assigned to work alternative, supervised under county parole, ordered to alcohol monitoring, or discharged from the program entirely. Each status has a different records path. A normal public jail roster may not show the person because the person is not housed in a jail unit, but that absence does not prove the person is free of conditions.
Alternative custody is often tied to a court order, Sheriff program placement, probation or pretrial supervision, or a later discharge. It can follow a Martinez booking, a West County or Marsh Creek custody period, or a court decision. The release record may be scattered across court minutes, custody program records, probation records, and VINE status if the custody change is in the participating agency feed. This page therefore focuses on the confirmation chain rather than a facility address or ordinary jail release list.
Confirm Alternative Custody
Do not start by looking for a separate public "Custody Alternative Facility release roster." The research did not identify a normal release feed for this program. Start by deciding what question you need answered: is the person in a jail bed, out of jail under conditions, transferred, or fully discharged? That question determines whether the right source is the Sheriff locator, the court, a program contact, probation, VINE, or Records & ID.
- Search the Sheriff In-Custody Locator to see whether the person still appears in county jail custody.
- If no current custody result appears, check California VINE for custody-status changes if the person was in a participating custody feed.
- Review Contra Costa Superior Court records for release-to-program language, pretrial conditions, work alternative orders, county parole, monitoring requirements, sentence changes, or discharge orders.
- Use Sheriff custody contacts or Records & ID when the question is a formal custody or alternative-custody record.
- Check Contra Costa Probation when the status is probation, PRCS, mandatory supervision, pretrial supervision, or local community supervision.
- Do not call the person fully discharged unless a court record, Sheriff record, probation source, or supervising program confirms discharge.
The broader county workflow on Home separates current jail custody, release records, court disposition, CDCR state-prison records, federal custody, and immigration records. Alternative custody belongs in that middle area: the person is often outside jail but still connected to a court or supervision framework.
Custody Alternative Records
The research source lists Custody Alternative through the Sheriff's Custody Services Bureau rather than as a standard public jail facility with a facility page, street address, and ordinary release desk. For public-record routing, use the Sheriff custody services path and Records & ID, then use the court or probation when the record belongs there. Program-specific conditions may not be public, and health, monitoring, juvenile, sealed, or confidential supervision details may be restricted.

The court side may be just as important. Contra Costa Superior Court records can show the order that placed the person in a program, modified custody, set pretrial release terms, imposed probation, or terminated supervision. The court page states that minutes, case documents, and orders are not available online, so copies require the court records process.
About Custody Alternative
Custody alternative programs are designed for cases where the person does not need to occupy a standard jail bed or where the court and custody system authorize a monitored community placement. The Sheriff fact sheet names electronic home detention, work alternative, county parole, alcohol monitoring, and pretrial release. Those categories are not interchangeable. Electronic home detention is not the same as probation. Work alternative is not the same as a dismissed case. County parole is not the same as CDCR state parole. Pretrial release is not the same as post-sentence discharge.
Because the categories differ, the page avoids saying that every person in a custody alternative program is a "released inmate" in the same way. The better phrasing is "out of a jail bed under alternative custody or supervision." That wording fits the source material and protects readers from assuming a person has no remaining court date, check-in, device requirement, alcohol monitoring requirement, work obligation, or supervision condition.
Program Status Differences
| Status | What it can mean | Where to verify |
|---|---|---|
| Electronic home detention | Out of jail but monitored under program rules. | Court order, Sheriff custody alternative, Records & ID. |
| Work alternative | Sentence or custody obligation performed through approved work terms. | Court sentence, program record, Sheriff contact. |
| County parole | Local custody-related supervision, distinct from CDCR parole. | Court, Sheriff, probation or local supervision source. |
| Alcohol monitoring | Release or supervision condition involving monitoring. | Court order and supervising program. |
| Pretrial release | Released while charges continue, subject to court conditions. | Court portal, court records, pretrial or probation source. |
Records Boundaries
Alternative-custody records may be less visible than jail custody records. The public locator may stop showing a person when the person is outside a jail bed. VINE may show a custody change but not the full legal reason or program terms. Court records may identify an order but not every operational detail. Sheriff Records & ID may process records requests, but exemptions, privacy rules, sealed records, and law-enforcement limits can apply. If the person is a juvenile, the adult alternative-custody path is not the right model; use probation, juvenile court, family, or attorney channels instead.
