Check Marin County Juvenile Hall Custody

Marin Juvenile Hall Overview

Marin County Juvenile Hall is operated by Marin County Probation Department Juvenile Services. County pages describe Juvenile Hall as "not jail" and as a short-term place where children and youth may stay after getting into trouble. Police bring youth to Juvenile Hall, then Juvenile Probation staff take responsibility. Parents or guardians are contacted, and a counselor performs an initial screening and detention risk assessment.

The facility belongs in a Marin County detention map because it can hold youth, but it should not be described like Marin County Jail. It is not an adult inmate-search facility, does not use the adult booking log as a public roster, and should not be paired with adult mugshot language. The research found no public juvenile roster. Access to juvenile custody and case information should route through Probation, Juvenile Court, counsel, and a parent or guardian process rather than a public web list.

Marin Juvenile Hall Capacity

The 2024 Civil Grand Jury described Marin County Juvenile Hall as certified for 40 beds with a current daily average of about 8 youth. Current official Juvenile Hall pages inspected in the research file did not publish a bed count, so the Civil Grand Jury figure should be treated as a dated source rather than a current live capacity statement. Juvenile Hall population should also not be blended into adult jail population figures because the purpose, age group, records rules, and court process are different.

County materials state that children ages 12 to 18 may stay briefly after arrest. Most can go home soon after arrival. Some remain longer if the alleged conduct is serious, no safe alternative placement is available, the youth is not taking responsibility, or the youth presents a risk of harm or flight. If a child stays longer than 48 hours, the county page says they go to court.

Confirm Juvenile Custody

There is no public Marin County Juvenile Hall roster in the research file. A parent, guardian, attorney, or authorized party should use official juvenile channels rather than adult jail lookup tools. The Marin County Public Booking Log is for adult county jail custody and last-48-hours still-in-custody adult bookings. CDCR CIRIS is for sentenced state-prison custody. ICE ODLS does not search people under 18. Those systems should not be presented as juvenile roster substitutes.

1. Start with the parent or guardian notification process if Juvenile Probation has contacted the family.
2. Call Juvenile Hall or the Juvenile Division for general routing if the youth may have been taken there.
3. Work through counsel or the Public Defender when legal representation is involved.
4. Use Juvenile Court processes for hearing and case-record questions.
5. Do not rely on adult booking, mugshot, bail, or commissary pages as juvenile-record sources.

Marin Juvenile Hall Contact

County contact materials list Marin County Juvenile Hall at 4 Jeannette Prandi Way in San Rafael. The Public Defender juvenile-charges page also references 16 Jeannette Prandi Way for minors most likely taken to Juvenile Hall. Because the research contains both address references, arrival or mail details should be confirmed with the facility or Juvenile Division before travel. The phone numbers below come from the facility map and juvenile source notes.

Visit Juvenile Hall

Juvenile Hall visitation and contact should follow the official county Juvenile Hall visitation page. Adult jail rules should not be copied into this facility. The Marin County Jail schedule, GTL VisitMe process, Pigeonly mail address, adult commissary vendors, bail rules, and adult booking-log steps are not Juvenile Hall rules. Juvenile contact depends on the youth's status, family relationship, facility policy, and court or probation limits.

Parents and guardians should use the official visit your child in Juvenile Hall source for current rules. Because juvenile detention has privacy and safety limits, visiting information may be more controlled than adult jail information. Counsel and probation staff are the better route for case-specific access questions.

Juvenile Hall Contact Rules

The research file did not document adult-style commissary, money-deposit, phone-tablet, or Pigeonly mail procedures for Marin County Juvenile Hall. Those systems should not be imported from Marin County Jail. Juvenile Hall contact should be confirmed through the official county visitation/contact materials and Probation staff. Youth-detention rules are built around supervision, family involvement, court oversight, school, care, and safety rather than a public adult inmate account model.

Juvenile Intake Screening

Juvenile Hall intake is a probation screening process, not adult jail booking. County materials say police bring youth to Juvenile Hall, where Juvenile Probation staff take responsibility. Parents or guardians are contacted. A counselor conducts initial screening and creates a detention risk assessment. The key question is whether the youth can safely go home or needs to remain pending further court action. Most youth can go home soon after arrival.

A youth may stay longer when the alleged offense is serious, there is no safe alternative placement, the youth is not taking responsibility, or there is risk of harm or flight. If detention extends beyond 48 hours, the county source says the youth goes to court. Those timing and screening details should be treated as juvenile-probation facts, not adult bail or booking facts. Adult current-custody phone lines and adult exact-bail lines are not a substitute for juvenile probation routing.

Detention risk assessment

A juvenile probation screening tool used to decide whether a youth can go home or should remain detained.

Juvenile Court

The court process for youth matters, separate from adult criminal court records.

Parent or guardian notice

The family contact process described by county materials after youth arrival at Juvenile Hall.

No public roster

The research found no public Juvenile Hall list comparable to the adult booking log.

Juvenile Hall Caveats

Juvenile Hall should be read through the county's own caveat: it is "not jail." The facility is part of Marin County Probation Department Juvenile Services, while the adult county jail is operated by the Marin County Sheriff's Office Detention Services Bureau. That agency difference changes records access, lookup methods, family contact, terminology, and privacy limits. The adult jail can publish a Public Booking Log for current adult custody. Juvenile Hall does not have a public juvenile roster in the research file.

The 2024 Civil Grand Jury also discussed Juvenile Hall in broader justice-center context, describing it as a dated facility along with the adult jail. That does not change the immediate lookup rule. A youth custody question belongs with Probation, Juvenile Hall, counsel, parent or guardian channels, and Juvenile Court. The adult county jail, San Quentin, CDCR CIRIS, BOP, and ICE systems answer different custody questions.
