The Marin County Juvenile Hall is a medium to low-security detention center located at 16 Jeannette Prandi Way San Rafael, CA that is operated locally by the Juvenile Justice Department and holds youths awaiting the determination of punishment for the crimes of which they are accused. Most of the adolescents are here for less than two years.

The juvenile justice system differs from the adult system, focusing on rehabilitation and recognizing the developmental differences in juveniles. It aims to protect both the child and the public and helps juveniles become productive adults.

Juveniles are detained if they pose a threat, may miss court, or violate court orders. Parental involvement is crucial for effective supervision and rehabilitation.

Key differences in terminology include "taken into custody" instead of "arrest" and "supervision" instead of "probation." Referrals usually come from law enforcement, and an intake social worker decides the juvenile's placement. An inquiry can lead to dismissal, corrective action, or court involvement.

The process includes a plea hearing, possible evaluations, a pre-trial conference, a fact-finding hearing, and a dispositional hearing to determine the case's outcome. Parents may need to cover associated costs.

The Juvenile Hall provides 24 hour care to youth that have been detained under 602 or 601 of the Welfare and Institutions Code. Marin County Office of Education operates a school within Juvenile Hall and the Public Health Department has staff located within the facility to provide for medical needs. In addition to providing close supervision of detained youth, the Juvenile Hall offers a variety of recreational and support programs and on site food preparation in compliance with Title 15 (operations, staffing and training) and Title 24 (physical facility) of the California Code of Regulations. The Probation Department provides mental health services in Juvenile Hall, including an initial screening, crisis intervention and referrals to appropriate programming after release from custody. This service is integrated with the mental health program, PORTAL, which is located at Juvenile Services.

  • Is my child safe in Juvenile Hall?

    Most definitely. The Juvenile Hall operates with around the clock supervision, utilizing trained, professional group counselor staff, in conjunction with both mental and physical health professionals. Juvenile Hall staff includes mental health professionals, a nurse from the Public Health Department, and a consulting psychiatrist from the Community Mental Health Department.

  • When can I see my child?

    You can visit your child at any time within the first 24 hours of arrest. After that, visiting times are Saturday afternoon, from 2:30 PM to 3:30 PM, and Wednesday evenings, from 7:00 PM to 8:00 PM. Only parents or legal guardians are allowed to visit the youth detained in Juvenile Hall.

  • How long will my child be detained?

    Unless your child has been charged in the adult court, there is no bail allowed for minors in the State of California. The decisions to initially detain a child, and then how long they will remain detained, depend on many factors. Any detention lasting longer than 48 hours (not including weekends and holidays) will go through Juvenile Court and will allow you and your child legal representation.

    In order to get better idea of how long your child will remain detained, we urge you to contact the Juvenile Division Probation Department at (415) 473-6659, during normal business hours.

  • What does my child do all day while detained in Juvenile Hall?

    The Marin County Office of Education operates a school inside Juvenile Hall every school day of the year. All detained youth who are 18 years of age or younger attend this school. Youth who are detained for an extended period of time can arrange to have school work from their normal schools incorporated into the Juvenile Hall academic curriculum.

  • Who can I talk to about my child’s case?

    If your question is about your child’s stay in Juvenile Hall, such as specific concerns over their well-being, important information regarding their physical or mental health needs, or general questions about the operation of Juvenile Hall that are not covered in this brochure, please call the Juvenile Hall at (415) 473-6705.

    If your questions pertain to the length of your child’s stay in Juvenile Hall, or the legal process including Juvenile Court and/or probation, please contact the Juvenile Division of the Probation Department at (415) 473-6659 during normal business hours.

Frequently Asked Questions

Marin County Juvenile Hall - FAQs about Juvenile Detention Centers

  1. What is a juvenile detention center?
    A juvenile detention center is a secure facility designed to house minors who have been arrested, charged, or convicted of a crime. Unlike adult jails, these centers focus on rehabilitation, education, and structured supervision. Youth housed in these facilities may be awaiting trial, serving short-term sentences, or completing mandated treatment programs aimed at reducing delinquent behavior.

  2. How does a juvenile detention center differ from an adult jail?
    Juvenile detention centers differ from adult jails in their approach to discipline, rehabilitation, and environment. They prioritize counseling, education, and structured activities over punitive measures. While adult jails emphasize punishment and security, juvenile facilities are designed to address the root causes of delinquent behavior, such as trauma, lack of parental guidance, or substance abuse issues.

  3. Who can be sent to a juvenile detention center?
    Juvenile detention centers house minors under 18 who have been arrested for criminal activity, ranging from status offenses (such as truancy or curfew violations) to serious felonies like robbery or assault. Some youth may also be placed in detention for violating probation, running away from court-mandated programs, or awaiting transfer to another facility.

  4. What types of offenses lead to juvenile detention?
    Youth may be detained for a variety of offenses, including property crimes (theft, vandalism), drug-related offenses, assault, gang activity, or firearm possession. In some cases, juveniles are detained for non-criminal behavior, such as repeatedly skipping school or running away from home. The severity of the offense, prior record, and risk level typically determine whether a juvenile is detained or placed in an alternative program.

  5. How long do juveniles stay in detention centers?
    The length of stay depends on the case. Some juveniles are held for a few days or weeks while awaiting trial, while others may serve months or years depending on their sentence. Youth placed in long-term detention typically participate in rehabilitation programs, educational courses, and mental health counseling. Courts may also mandate step-down programs, where youth transition into community-based supervision before full release.

  6. Are juvenile records sealed after release?
    In many states, juvenile records are sealed or expunged once the individual reaches adulthood, provided they meet certain conditions. However, serious offenses such as violent felonies or sex crimes may remain on record, potentially affecting future employment, housing, and educational opportunities. In some cases, a juvenile may petition the court to have their record expunged after demonstrating rehabilitation.

  7. Do juveniles in detention attend school?
    Yes, most juvenile detention centers provide on-site educational programs that allow youth to continue their schooling while in custody. These programs may include core academic subjects, GED preparation, and vocational training. Some facilities work with local school districts to ensure that credits earned in detention transfer back to public schools upon release.

  8. Can family members visit juveniles in detention?
    Yes, but visitation policies vary by facility. Families typically need to schedule visits in advance, follow strict security protocols, and comply with dress code regulations. Some detention centers offer video visitation or family counseling sessions to strengthen relationships before the juvenile is released. Regular contact with family members can significantly reduce recidivism and improve rehabilitation outcomes.

  9. Are juveniles allowed to make phone calls?
    Most juvenile detention centers allow monitored phone calls, though the frequency and duration depend on facility rules, the youth’s behavior, and their case status. In some cases, juveniles may call only pre-approved family members or legal representatives. Facilities may also restrict calls if an inmate violates behavioral rules.

  10. What rehabilitation programs are available?
    Programs often include substance abuse counseling, anger management, cognitive-behavioral therapy, vocational training, and life skills workshops. These services are intended to help juveniles develop positive coping mechanisms, make better decisions, and reintegrate into their communities upon release. Some centers also offer mentorship programs where at-risk youth receive guidance from former inmates or community leaders.

  11. Are juveniles placed in solitary confinement?
    While some facilities still use room confinement or restricted housing as disciplinary measures, prolonged solitary confinement for juveniles is widely discouraged due to its negative psychological effects. Many states have passed laws limiting or banning solitary confinement for minors, encouraging the use of alternative discipline methods such as behavioral interventions and conflict resolution programs.

  12. Can juveniles be transferred to adult prison?
    In some cases, juveniles may be tried as adults for severe offenses, such as murder, armed robbery, or sexual assault. If convicted, they can be transferred to adult prison upon turning 18. Some states allow judges to reconsider these transfers based on the juvenile’s rehabilitation progress, age, and psychological evaluations.

  13. What rights do juveniles have in detention?
    Juveniles have the right to education, medical care, legal representation, and protection from abuse. They are also entitled to due process, meaning they cannot be detained indefinitely without a hearing. Inmates must be provided with access to rehabilitative services and fair treatment under the law. Any allegations of abuse or mistreatment must be investigated by oversight agencies.

  14. How do juveniles reintegrate into society after detention?
    Many juvenile detention centers offer reentry programs, including mentorship, transitional housing, probation supervision, and vocational training. Youth are often connected with caseworkers, social services, and education programs to help them successfully reintegrate. Some facilities also arrange family reunification counseling to strengthen support systems at home.

  15. What happens if a juvenile violates probation after release?
    If a juvenile violates probation, consequences can range from increased supervision and mandatory counseling to community service or re-detention. In severe cases, the juvenile may be returned to detention or sent to a more restrictive program. Courts typically evaluate the circumstances of the violation, the individual’s progress, and any external factors before making a decision.
