Call Marin County Juvenile Hall directly at 415-499-6705 - this is the fastest confirmation. Juvenile facility rosters are not always publicly searchable in the same way adult jail rosters are, because juvenile records are confidential in most states.
Steps to confirm your child is at Marin County Juvenile Hall:
1. Call 415-499-6705 and identify yourself as the parent or legal guardian
2. Provide your child's full legal name and date of birth
3. Ask for confirmation of admission and the name of the assigned case manager or youth advocate
4. Ask what the next scheduled court date is and which court it is in
If you have not been notified of the detention and you believe your child may have been arrested, also contact the arresting law enforcement agency and California juvenile court for your jurisdiction.
Yes - and this is one of the most important things to understand immediately.
In most states, law enforcement is required to notify a parent or legal guardian promptly after a juvenile is taken into custody. In many states, a juvenile cannot be questioned without a parent or guardian present, or without a knowing and voluntary waiver of that right. If your child was questioned before you were notified, document that and consult a juvenile defense attorney immediately.
Your rights as a parent during juvenile detention typically include:
-- The right to be notified of the detention promptly
-- The right to visit during approved hours
-- The right to communicate with your child by phone
-- The right to be present at court hearings
-- The right to retain legal counsel for your child
Contact Marin County Juvenile Hall at 415-499-6705 immediately, identify yourself as the parent or guardian, and ask to be connected with your child's assigned case manager or youth advocate. Ask what proceedings are underway and what your participation rights are.
Juvenile court is a separate court system designed for young people, with a focus on rehabilitation rather than punishment. Key differences from adult criminal court:
Confidentiality: Juvenile proceedings and records are typically confidential in California. This protects your child's record from public access in most circumstances.
Disposition not conviction: The outcome of a juvenile proceeding is a disposition, not a criminal conviction. This distinction matters for your child's future - a juvenile disposition generally does not carry the same lifelong consequences as an adult conviction.
No jury trial in most cases: A juvenile court judge makes the determination, not a jury.
Rehabilitation focus: Juvenile courts have access to a range of interventions - counseling, community service, probation, treatment programs - that are not typically available in adult court.
Adult court transfer: Serious offenses and repeat offenders can be transferred to adult court in California. If adult court transfer is possible in your child's case, a juvenile defense attorney needs to be involved immediately. An adult conviction follows your child for life in ways a juvenile disposition typically does not.
Contact a licensed juvenile defense attorney in California as soon as possible. Read InmateAid's what to expect guide for general context on the justice process.
Juvenile detention does not use traditional bail in most states. Instead, a detention hearing is typically held within 24 to 72 hours of admission. At that hearing a juvenile court judge determines whether your child should remain detained or be released to parent or guardian custody with conditions.
Factors the judge considers include the nature of the offense, prior record, whether the young person is a flight risk, and whether release to a parent or guardian provides adequate supervision and community safety.
If your child is held following a detention hearing, subsequent hearings are scheduled on a timeline set by California juvenile justice law. A juvenile defense attorney can petition for release at any stage.
For cases where adult court transfer has occurred and traditional bail applies, read InmateAid's bail and bond guide for a full walkthrough.
Visitation rules at juvenile detention facilities are set by the facility and California juvenile justice regulations. Contact Marin County Juvenile Hall at 415-499-6705 to confirm:

Frequently Asked Questions about Marin County Juvenile Hall
How do I confirm my child is at Marin County Juvenile Hall?
Call 415-499-6705 and identify yourself as the parent or legal guardian. Juvenile facility rosters are confidential and not publicly searchable - direct contact with the facility is the fastest and often only way to confirm placement.
Can my child be questioned without me present?
In most states a juvenile cannot be questioned without a parent or guardian present, or without a knowing and voluntary waiver of that right. If your child was questioned before you were notified, document that and contact a juvenile defense attorney immediately.
Will this result in a criminal record?
Juvenile records are typically confidential and may be sealed or expunged when your child turns 18, depending on California law and the nature of the offense. However, serious offenses can result in adult court transfer, which creates a permanent adult record. Contact a juvenile defense attorney for guidance specific to your child's situation.
How long can my child be held before a court hearing?
In most states a detention hearing must be held within 24 to 72 hours of admission. The juvenile court judge determines at that hearing whether to release your child to parent custody or continue detention. Contact 415-499-6705 for the scheduled hearing date and time.
Can I bring things when I visit?
Contact 415-499-6705 to confirm what is permitted. Most juvenile facilities restrict what visitors can bring - typically only valid ID is required, and items for the young person must be approved in advance through proper channels rather than brought during a visit.
Juvenile detention is frightening for everyone involved - for the young person inside and for the family outside. The system is designed with different goals than adult incarceration, and most of the time the path through it is shorter and less permanent than families fear in those first hours. What matters most right now is getting connected - to the facility, to a good juvenile defense attorney, and to as much information as you can find.
