Ontario, California Involuntary Mental Health Hold Rules

Public Health and Welfare California 4 Minutes Read · published February 20, 2026 Flag of California

In Ontario, California, involuntary mental health holds are civil evaluations used when a person appears to be a danger to themselves or others or gravely disabled due to a mental disorder. Local law enforcement and designated mental health professionals work with San Bernardino County behavioral health services and county treatment facilities to evaluate and, when necessary, detain a person for up to 72 hours for psychiatric assessment under state law. For city residents this page explains how the process starts, who enforces it, the review and appeal pathways, and how to get help.

If someone is an immediate danger call 911 and request a crisis response.

Legal Basis and Who May Place a Hold

The primary legal authority for short-term involuntary detention is Welfare and Institutions Code section 5150, which authorizes a 72-hour hold for evaluation and treatment when specified criteria are met. Local officers and designated county mental health personnel carry out evaluations and transport to county-designated facilities for assessment Welf. & Inst. Code § 5150[1].

Penalties & Enforcement

Involuntary mental health holds under California law are civil, not criminal, processes focused on evaluation and care rather than fines or criminal penalties. Monetary fines for placing or failing to place a hold are not specified on the cited state or county pages; enforcement and remedy procedures focus on civil review and administrative actions where applicable Welf. & Inst. Code § 5150[1] and local county guidance San Bernardino County Department of Behavioral Health - Crisis Services[2].

  • Enforcer - law enforcement officers and designated mental health professionals coordinate with San Bernardino County DBH to initiate holds and arrange transport.
  • Standard detention period - up to 72 hours for evaluation under WIC 5150; further holds require separate statutory authority.
  • Facility action - county-designated psychiatric facilities receive and assess individuals placed on hold.
  • Complaint or review - contact the City of Ontario Police Department or San Bernardino County DBH for issues about process or conduct.
A 5150 hold is a civil detention for assessment, not a criminal arrest.

Applications & Forms

No public application form is required to initiate a 5150 evaluation; holds are initiated by qualified individuals or officers based on observed criteria. If a specific administrative or appeals form exists it will be provided by the receiving county facility or DBH intake office, but no general public form is published for initiating a hold San Bernardino County Department of Behavioral Health - Crisis Services[2].

How the Local Process Works

Typical steps taken in Ontario include initial contact or 911 dispatch, on-scene evaluation by officers or crisis teams, transport to a county-designated facility if criteria are met, and a psychiatric evaluation during the 72-hour period. County behavioral health offers crisis teams and designated facilities that receive persons on holds and manage next-step treatment or discharge planning San Bernardino County Department of Behavioral Health - Crisis Services[2].

  • For emergencies call 911 and request a crisis response.
  • Officers complete required evaluation paperwork and facility intake forms when transporting a person placed on a hold.
  • Receiving facilities document clinical findings and notify relatives or representatives consistent with law and facility policy.
County crisis teams support law enforcement with on-scene mental health expertise.

Appeals, Review and Legal Rights

Individuals detained under 5150 have civil rights including the right to a timely psychiatric evaluation and to receive information about their status; processes for challenge or review of continued involuntary treatment are governed by state law and facility procedures. Time limits for initial detention are statutory (72 hours); any extension or involuntary commitment beyond that term must follow statutory procedures and authorizations such as WIC 5250 for extended holds where applicable Welf. & Inst. Code § 5150[1]. For administrative complaints about city response, contact the City of Ontario Police Department internal affairs or civilian complaint process City of Ontario Police Department[3].

  • Appeal/Review - procedural protections and review mechanisms are available under state law and facility policies; specific timelines for administrative appeals are not specified on the cited county pages.
  • To report concerns about police conduct call the City of Ontario Police non-emergency line or use the civilian complaint procedure.
  • Legal counsel - seek civil rights or mental health law counsel for representation in extended commitment hearings.
If you believe rights were violated gather records and contact the facility's patient advocate or county DBH intake.
