California 5150 Hold: Criteria, Rights, and Firearm Consequences

A California 5150 hold is a civil process that lets certain authorized professionals detain a person for up to 72 hours of involuntary psychiatric evaluation when, because of a mental health disorder, that person is a danger to themselves, a danger to others, or gravely disabled.¹ The clock starts at the moment of initial detention, not on arrival at a facility. It is not a criminal charge, but it carries consequences for firearm rights, medical records, and follow-up treatment that most people don’t learn about until after the fact.

When the Criteria Are Met

A hold requires at least one of three findings, and each must stem from a mental health disorder:

Danger to self: an attempt, a threat, or a pattern of behavior suggesting self-harm. A recent suicide attempt is the most common example, but not the only one.
Danger to others: the person’s mental condition makes physical harm to someone else likely, whether through specific threats, violent conduct, or an escalating pattern a trained professional recognizes.
Gravely disabled: the mental health disorder leaves the person unable to meet basic needs. Being unhoused alone does not qualify. The question is whether the person’s mental state prevents them from using available resources to survive, even with help from family or others willing to assist.²

The danger does not have to be imminent. Under Section 5150.05, the professional making the call “shall not be limited to consideration of the danger of imminent harm” and can weigh the historical course of the person’s disorder, including information from family members, past providers, and the person themselves.³ Someone with a documented pattern of dangerous decompensation can be placed on a hold before the crisis reaches its worst point.

Senate Bill 43, with a final statewide implementation deadline of January 1, 2026, broadened the “gravely disabled” definition. It now reaches people whose inability to care for themselves stems from a severe substance use disorder, or a co-occurring mental health disorder and severe substance use disorder, and it now includes the inability to provide for one’s own personal safety or necessary medical care, not just food, clothing, and shelter.⁴

Who Can Actually Place Someone on a Hold

Family, friends, and coworkers cannot initiate a 5150 directly, no matter how alarming the behavior. Only these categories of professionals have that authority:

Peace officers, who are the most common initiators during emergency calls.
County-designated mobile crisis team members, who can evaluate in the field without involving law enforcement.
The professional person in charge of a county-designated evaluation and treatment facility, along with designated attending staff.
Other mental health professionals a county has designated for this authority.¹

What family members can do is call 911 or a county crisis line and provide the observations that feed the probable cause determination. Be specific: concrete behaviors, statements, and recent changes are far more useful than “they seem off.” Anyone who provides a statement to support a hold can be sued civilly for intentionally false statements, which is the system’s built-in check against misuse.

What Happens During the 72 Hours

The 72 hours is a maximum, not a guaranteed length of stay, and it starts at initial detention. Time in transport and in an emergency department waiting room counts toward the total.¹ Some counties exclude weekends and holidays, which can extend the actual calendar time in the facility. The written notice the facility hands the patient must state when the 72-hour period began.

On arrival, staff are first supposed to assess whether the person truly needs to be detained or whether voluntary evaluation and crisis intervention will work instead. Admission is not automatic just because someone shows up in custody. For those who are admitted, a team of psychiatrists, nurses, and social workers evaluates the person on an ongoing basis. If the treating psychiatrist decides at any point that the person no longer meets the criteria, the facility must release them. Nothing in the law requires a patient to stay for the full 72 hours.

The End of the 72 Hours

Three outcomes are possible. Most often the person is released, sometimes with an outpatient referral. A person willing to keep treatment going may stay voluntarily. The third option, for someone who remains actively dangerous or gravely disabled, is certification for a 14-day involuntary hold under Section 5250. Within four days of certification, the patient has the right to a certification review hearing before a court-appointed hearing officer or judge, with the right to an attorney or advocate, to present evidence, and to question the facility staff who signed the certification. If probable cause is not shown, the person must be released.⁵

Rights During the Hold

Involuntary detention does not strip away civil rights. The facility must give both oral and written notice, in the patient’s primary language, explaining why they are being held, when the 72-hour period began, and how to reach a patients’ rights advocate.¹ Beyond that:

You have the right to make and receive confidential phone calls to family, friends, or an attorney.⁶
You can contact a patients’ rights advocate, who is independent of the clinical team and investigates complaints about treatment or conditions.
You can refuse antipsychotic medication except in a genuine medical emergency where your life or someone else’s safety is at immediate risk.
You can request evaluation or treatment at a facility or by a professional of your choosing. Availability is not guaranteed, but the request must be honored when possible.

If the facility wants to give antipsychotic medication over a patient’s refusal outside an emergency, it must go through a Riese hearing. A hearing officer or judge decides whether the patient has capacity to make treatment decisions, meaning whether they understand the situation, can weigh risks and benefits, and can participate rationally in the choice.⁶ Disagreement with the patient’s choice is not enough.

The hold itself can be challenged through a writ of habeas corpus. The request can be made to any treatment staff member or to the person delivering the certification notice, at any time during detention. That staff member must promptly notify the superior court in the county where the facility sits. Blocking or ignoring the request is a misdemeanor.⁷ A family member or attorney can file on the patient’s behalf.

Discharge Planning

Before releasing someone from a psychiatric hold, the facility must prepare a written aftercare plan. It goes to the patient, to any conservator or legal representative, and to anyone else the patient designates. Staff must tell the patient about the right to designate someone to receive a copy.⁸ To the extent the information is known, the plan must include an explanation of the illness and follow-up care needed, a list of medications with dosages and side effects, the expected course of recovery, treatment recommendations, and referrals to mental health and medical providers. A discharge without this plan is a legal failure by the facility, and the patients’ rights advocate is the right person to contact.

Firearm Consequences

This is the part that blindsides people. Someone taken into custody under Section 5150 as a danger to self or others, assessed, and admitted to a designated facility is banned from owning, possessing, or purchasing any firearm, deadly weapon, or ammunition for five years after release. The facility must report the admission to the California Department of Justice within 24 hours and must inform the person of the prohibition before or at discharge.⁹ Two or more danger-to-self-or-others admissions within a single year makes the prohibition permanent. Any existing firearms, weapons, or ammunition must be relinquished within 72 hours of discharge.

There is a path to restore rights. During the five-year period, the person can file a single petition in the superior court of their county of residence. At the hearing, the burden of proof falls on the state: the district attorney must show by a preponderance of the evidence that the person would not be likely to use firearms safely and lawfully. If the state cannot meet that burden, the court lifts the prohibition.⁹

Federal law under 18 U.S.C. § 922(g)(4) separately prohibits anyone “committed to a mental institution” from possessing firearms, but the federal definition explicitly excludes a person held “for observation.”¹⁰ Many legal analysts treat a 5150 as falling within that observation exclusion because it is an evaluation, not a court-ordered commitment. California’s five-year state ban applies either way, and a firearms attorney is the right resource for anyone actually navigating this.

Records, Privacy, and Background Checks

A 5150 is a civil matter. It does not appear on a criminal record, and standard employment background checks will not show it. Medical records from the hold are protected by HIPAA like any other health information and generally cannot be released without authorization.¹¹

The exceptions matter. The Department of Justice report tied to firearm screening will surface on any background check connected to purchasing a firearm or applying for a concealed carry permit. Background checks for law enforcement positions and certain government security clearances may reach mental health hold records, and some professional licensing boards, particularly in healthcare and law, ask about involuntary holds on their applications.

For family communication during the hold, HIPAA allows providers to share information with family or friends involved in the patient’s care if the patient is present and does not object. If the patient is incapacitated, providers may share information they judge, in their professional discretion, to be in the patient’s best interest. Either way, what’s shared has to be limited to what is directly relevant to that person’s role in the care.¹¹

Insurance and the Bills That Follow

An involuntary psychiatric hold generates real medical bills. California’s Mental Health Parity Act requires state-regulated commercial health plans to cover mental health treatment, including inpatient care, on the same terms as physical health treatment. Copays, deductibles, and out-of-pocket maximums for mental health services cannot be more restrictive than those for medical and surgical benefits.¹² Medi-Cal also covers inpatient mental health services.

Parity is not zero cost. Copays, coinsurance, and deductibles still apply, and ambulance transport generates a separate bill. The harder fact for families is that the detained person had no say in the facility, the providers, or the level of care, yet the bills arrive in their name. Complaints about parity violations go to the California Department of Managed Health Care for HMO and PPO plans, and to the Department of Insurance for other coverage.
