- 01Confirm housing

These details are not published.
Ask the facility before setting out. Jail411 will not guess at a rule that could cause a missed visit.
- A public searchable roster of youth in custody

John A. Davis Juvenile Hall mail address.
Official Juvenile Hall page (checked 2026-09-12) does not publish a family mail-address block or a youth-name format. Call (925) 957-2700 before you mail. Do not use Pigeonly PO Box 96777 Las Vegas (adult codes 1117 / 1118 / 1119).

Postage: Questions about a youth’s case, court hearing, or plans after leaving the hall go to the assigned Probation Officer, (925) 313-4000 — not hall visiting staff.
How youth phone calls work
Hall (925) 957-2700 Monday–Friday 8 a.m.–5 p.m. After 5 p.m. and weekends (925) 957-2740. Special visits (925) 957-2725. Probation Martinez (925) 313-4000 for the assigned officer. A 2021 Probation release said the Department absorbs youth call costs at Juvenile Hall instead of collect calls. The 2026 Juvenile Hall HTML does not name a current family phone-account vendor. Do not open an adult-jail collect account and assume it works here. Call the hall. Call (925) 957-2700 rather than the adult jail (925) 335-4600.
Money
Can families send money here?
Juvenile Hall visiting page (checked 2026-09-12) does not publish a family commissary, deposit vendor, or “money on the books” path. Do not use MyCarePack, SmartDeposit, or Pigeonly. Call (925) 957-2700 if you have a question about property the hall allows. Bail is a Juvenile Court question — the adult jail bond process is not this hall.
This is not the adult jail deposit or commissary process. Do not send adult-inmate funds through a youth-campus workflow.

School, medical care, and programs.
These details come from the official youth-campus pages. Rules can change; use the linked county pages when you need to act.
Who can be held at this hall
Official Juvenile Hall page (checked 2026-09-12): 270-bed maximum-security detention for youth offenders up to age 25. Youth are classified by gender, age, offense, and special needs. Probation Juvenile Services: in-custody intake books youth for more serious offenses (WIC § 602); assessment may release to a parent, Home Supervision, or detain. Adult jail booking is a different system.
Official page states 270 beds. Inventory listed 290 — the live Probation HTML (270) is what this handbook uses.
Mt. McKinley School
Official Juvenile Hall page: Contra Costa County Office of Education operates Mt. McKinley School, a fully accredited year-round school. Youth attend Monday through Friday and can work toward a GED or high school diploma. Depending on commitment, college credit or trade school may be available. Library opened November 2006 in the education wing, staffed by Contra Costa County Library.
Official education page ↗Medical and mental health
Official Juvenile Hall page: medical, mental health, and cognitive behavioral treatment through Contra Costa County Health Services. Two treatment programs; all youth receive CBT from specially trained Probation staff. Call (925) 957-2700.

PREA / sexual-abuse prevention
Probation Services Document Center publishes Sexual Abuse Prevention Detection and Response, PREA FAQs, Non-Discrimination and Sexual Harassment, and Transgender Youth in Juvenile Hall. Adult-jail PREA is a Sheriff Custody page and does not apply here. Ask Juvenile Hall (925) 957-2700 or Probation (925) 313-4000.
Official PREA page ↗Programs named on official Probation pages
These are facility programs, not a visiting menu.
- Cognitive Behavioral Treatment from trained Probation staff

- Home Supervision / juvenile electronic monitoring (a community alternative — not this housing door)
- Briones Youth Academy / Secure Pathway (named in June 2026 Probation news as a Juvenile Hall pathway — call the hall for current housing)
