A 5150 hold is a 72-hour involuntary psychiatric detention authorized under California law. It allows designated professionals to place someone in a mental health facility against their will when that person, due to a mental health disorder, poses a danger to themselves, a danger to others, or is gravely disabled. The term “5150” comes from Section 5150 of the California Welfare and Institutions Code, part of the Lanterman-Petris-Short (LPS) Act passed in 1967.
The Three Legal Criteria
A 5150 hold can only be initiated when at least one of three conditions is met, and the condition must be the result of a mental health disorder. Simply being intoxicated, angry, or eccentric is not enough.
- Danger to self: The person is at risk of harming or killing themselves. This can include active suicidal behavior, recent suicide attempts, or clear statements of intent paired with the means to follow through.
- Danger to others: The person presents an immediate threat of physical harm to another person. Vague anger or verbal arguments typically don’t qualify. The evaluator needs to identify specific behaviors or statements that indicate real, imminent risk.
- Gravely disabled: The person is unable to provide for their own basic needs of food, clothing, or shelter because of a mental health disorder. Someone who is psychotic and wandering the streets in freezing temperatures without awareness of their situation, for example, could meet this criterion.
As of 2024, California Senate Bill 43 expanded the definition of grave disability. The law now includes people who cannot meet their basic needs due to a severe substance use disorder, or a co-occurring mental health and substance use disorder. The definition of “basic needs” was also broadened to cover medical care and personal safety, not just food, clothing, and shelter. Counties are implementing these changes on a rolling basis through January 2026.
Who Can Place a 5150 Hold
Not just anyone can initiate a 5150. California law limits this authority to specific people: peace officers, licensed mental health professionals working in designated facilities, licensed physicians in hospital emergency departments, board-registered mental health professionals working under supervision, and in some areas, specially trained paramedics. Mental health professionals approved by a county’s behavioral health director may also qualify. Student interns, peer support staff, non-clinical workers, and private practitioners cannot place someone on a 5150 hold.
The person initiating the hold must complete an application documenting the specific facts and observations that led them to believe the individual meets at least one of the three criteria. This isn’t a checkbox exercise. The form requires a description of the person’s behavior, statements, and history, essentially building a case for why the hold is justified based on probable cause.
What Happens During the 72 Hours
Once placed on a 5150 hold, the person is transported to an LPS-designated facility. These are specific mental health treatment facilities approved by both the county and the California Department of Health Care Services. They include licensed psychiatric hospitals, psychiatric health facilities, and certified crisis stabilization units. A regular hospital emergency room is not an LPS-designated facility, though someone might be initially evaluated there before being transferred to one.
During the hold, a clinical team evaluates the person’s mental health, assesses their level of risk, and provides crisis intervention. The 72-hour clock starts when the person arrives at the designated facility, not when they were first detained. Weekends and holidays count toward the 72 hours.
The person retains certain rights during this period. They can make phone calls, receive visitors, and refuse certain treatments in some circumstances. They also have the right to contact a patients’ rights advocate. A 5150 hold is not a criminal arrest. It does not result in a criminal record, though it is documented in medical records and can affect a person’s ability to purchase firearms in California for five years.
How a Hold Can Be Extended
Most people placed on a 5150 hold are released within the 72-hour window, either because their crisis stabilizes or because they agree to continue treatment voluntarily. But if the treatment team determines the person still meets criteria after evaluation, the facility can file for a 14-day extension known as a 5250 hold, formally called a “certification for intensive treatment.”
Two conditions must be met for a 5250. First, professional staff must determine the person remains a danger to themselves, a danger to others, or gravely disabled. Second, the person must have been offered voluntary treatment and either refused it or been unable to accept it. The facility then conducts a certification review hearing within four days of the 72-hour hold ending. At this hearing, the person can be represented by a patients’ rights advocate or another person of their choice, and they can request that family members attend, including by telephone, to help explain their circumstances.
If the person disagrees with the 5250 certification, they can challenge it. The hearing process exists specifically to protect against unjustified detention.
5150 Holds Outside California
The term “5150” is specific to California. Every U.S. state has its own version of an involuntary psychiatric hold law, and most use similar criteria: danger to self, danger to others, or inability to care for oneself. Florida’s equivalent is the Baker Act, which allows a 72-hour hold. In Texas, it’s called an Emergency Detention Order. New York uses the Mental Hygiene Law. The hold durations, who can initiate them, and the hearing processes vary by state, but the core concept is the same: temporary involuntary detention for psychiatric evaluation when someone is in immediate crisis.
The 72-hour timeframe is common across many states, though some allow shorter or longer initial holds. What makes California’s 5150 distinctive is its detailed framework for escalating holds (from 72 hours to 14 days to 30 days) with increasing levels of legal oversight at each step.
What It Means for the Person Held
Being placed on a 5150 can be frightening, disorienting, and in some cases, life-saving. For the person being held, it typically means being transported by ambulance or police car to a psychiatric facility, having personal belongings temporarily taken, being evaluated by a psychiatrist or other mental health professional, and being placed in a secure unit where they cannot leave. Some people experience the hold as a critical turning point that connected them to treatment they needed. Others experience it as traumatic, particularly if the facility is overcrowded or the process feels dehumanizing.
For family members, a 5150 hold often represents the moment when a loved one’s mental health crisis exceeded what could be managed at home. Families do not have the legal authority to place someone on a 5150 themselves, but they can call 911 or a mobile crisis team, who can then evaluate the person and initiate a hold if the criteria are met. Many counties also operate crisis hotlines staffed by mental health professionals who can dispatch mobile teams to assess the situation in person.
