5150 refers to section 5150 of the California Welfare and Institutions Code, the state law that allows certain professionals to place a person on an involuntary psychiatric hold, commonly called a 5150 hold, for up to 72 hours of assessment, evaluation and treatment when, because of a mental health disorder, they are a danger to themselves, a danger to others, or gravely disabled [1]. It is not a criminal arrest, and the hold creates a medical record, not a criminal one.
For families in Los Angeles watching a loved one spiral through a mental health crisis, addiction, or both at once, understanding this section of California law matters more than ever, because as of January 1, 2026, LA County also applies it to severe substance use disorder [2]. Many people who come off a hold need continued care for co-occurring conditions, the kind delivered through dual diagnosis treatment that addresses mental health and addiction together. This chapter explains the hold in plain language; the bigger decision of where treatment happens afterward is covered in our guide on how to choose a rehab.
The Three Criteria for a 5150 Hold in California

A 5150 requires probable cause that the person meets at least one statutory criterion. Under the expanded 2026 grave-disability definition, grave disability may result from a mental health disorder, severe substance use disorder, or both [1]:
- Danger to self. Danger to self can include suicidal intent, a suicide attempt, serious self-harming behavior, or other conduct showing a substantial risk of harm. California law does not require the decision to be limited to imminent danger, and relevant history may also be considered.
- Danger to others. Credible threats or violent behavior that put another person’s safety at risk.
- Gravely disabled. Gravely disabled means that, because of a mental health disorder, severe substance use disorder, or both, the person is unable to provide for basic personal needs for food, clothing, shelter, personal safety, or necessary medical care.
These are legal criteria, not medical diagnoses. The person initiating the hold does not diagnose anyone; they document observable behavior that supports probable cause, and a psychiatric evaluation follows at the receiving facility [1] [3].
What Changed in 2026: Severe Substance Use Disorder Now Counts
Senate Bill 43 rewrote the gravely disabled standard for the first time in decades, and Los Angeles County implemented it on January 1, 2026 [2]. A person may now be considered gravely disabled as a result of a mental health disorder, a severe substance use disorder, or both together, if they cannot provide for their basic needs for food, clothing, shelter, personal safety, or necessary medical care [2]. Before SB 43, severe substance use disorder by itself was not a basis for grave disability under the standard 5150 framework, although other legal mechanisms and co-occurring mental-health conditions could still affect involuntary intervention.
For families, the distinction matters: a loved one whose drug or alcohol use has made them incapable of keeping themselves safe can now qualify for a 5150 hold and, in extended cases, an LPS conservatorship under the Lanterman-Petris-Short Act [2]. A 5150 provides short-term assessment, crisis intervention, and treatment when needed, but it is not a substitute for ongoing mental-health or substance use treatment, which is covered in our chapter on how to get someone into rehab.
Who Can Start a 5150 Hold
Under the Welfare and Institutions Code, a hold may be initiated by a peace officer, the professional person in charge of a facility designated by the county for evaluation and treatment, a member of that facility’s attending staff, designated members of a mobile crisis team, or another professional person designated by the county [1]. The statute’s repeated phrase professional person simply means a county-authorized clinician, and attending staff at designated hospitals apply it daily. In Los Angeles County, that means a police officer or an individual the Department of Mental Health has LPS-authorized [2].
Family members cannot place a hold themselves, but they can call 911, request a mobile crisis response instead of a standard police officer response when safe, and give first-hand information that establishes probable cause. Mental health professionals rely heavily on what families report, and mental health professionals will also ask about substance use directly now that it counts toward grave disability.
What Happens During the 72 Hours
The 72-hour period begins when the person is first detained, not when they arrive at a facility [1]. What follows, typically:
- Transport and medical clearance, often through an emergency department, to rule out medical causes and stabilize any physical problems.
- The person may receive assessment, evaluation, and crisis intervention in an appropriate setting or may be placed in an LPS-designated facility for evaluation and treatment. Under SB 43, a severe-SUD-only 5150 can initially be evaluated in certain settings such as an emergency department, crisis stabilization unit, or hospital medical unit. [1]. The designated facility must advise the person of their rights.
- Assessment, crisis intervention, and a treatment plan while evaluation and treatment continue; the person may be offered medication and mental health treatment, and the psychiatric facility documents progress throughout.
- Release, voluntary admission, or certification. Release can happen well before the full period runs; 72 hours is a maximum, not a sentence. Some people convert to voluntary treatment and stay as a voluntary patient. If criteria still exist and the person will not accept help, the facility can certify a longer hold.
One point LA County makes explicitly: a 5150 hold authorizes detention and assessment, including substance use disorder assessment, but it does not by itself authorize involuntary medication or other involuntary medical treatment outside emergency circumstances [2].
What Is a 5250 Hold?
If the treating staff believe the person still meets criteria at the end of the 72 hours, they can file a 5250 hold, a certification for up to 14 additional days of intensive involuntary treatment [3]. The safeguards scale up with the stakes:
- A certification hearing, an informal hearing held within four days, where a hearing officer decides whether the evidence supports continued involuntary detention.
- A patient’s rights advocate to assist the person, and the legal right to petition the superior court for a writ of habeas corpus, with a qualified attorney, to challenge the hold.
- Additional involuntary treatment is possible only under separate statutory standards. These can include up to 14 additional days for a person who remains an imminent suicide threat, up to two additional 30-day periods for qualifying grave disability, an up-to-180-day post-certification process in narrowly defined danger-to-others cases, and, when statutory requirements are met, LPS conservatorship proceedings [3].
The difference between a 5150 and a 5250 in one line: the 5150 is a 72-hour evaluation window; the 5250 is a certified 14-day treatment period with a mandatory hearing.
Who Pays for a 5150 Hold in California?
The hold itself is a legal mechanism, but the care delivered during a 72-hour stay is medical care, billed like other emergency services. Private insurance generally covers psychiatric emergency care and inpatient stays because mental health and substance use services are essential health benefits under federal law, subject to the plan’s normal deductibles and cost sharing [4]. Medi-Cal covers hold-related care for its members, and county programs absorb costs for many people without coverage. Bills vary widely by facility and length of stay, so families should ask the hospital’s billing office and the health plan directly. Financial worry should never delay a 911 call when someone’s safety is at immediate risk.
What a 5150 Does and Does Not Mean Long Term
A hold is a medical event, and a mental health condition is a health condition, not a character verdict. A 5150 hold does not create a criminal record, and it is not visible the way a criminal arrest would be. Two consequences are worth knowing: California law imposes a five-year firearm prohibition after certain holds where the person was admitted as a danger to self or others [3], and the hospitalization becomes part of the person’s medical record, protected by privacy law. People placed on emergency holds are people in crisis, and with follow-up care and family support, many stabilize and do well.
After the Hold: Turning a Crisis Into Care

Emergency holds provide short-term stabilization and evaluation; ongoing treatment may be needed to address the underlying mental-health or substance use condition. Families can use the moment to arrange an assessment at a treatment facility for the right level of ongoing care, whether that is residential treatment for stabilization, dual diagnosis care for co-occurring conditions, or structured outpatient care; our chapter on inpatient vs outpatient rehab explains how that choice gets made.
In any active crisis, call 911, or call or text 988 for the Suicide and Crisis Lifeline, available 24/7 [5]. SAMHSA’s National Helpline at 1-800-662-HELP (4357) offers free, confidential treatment referrals [5].
What Does 5150 Mean? Frequently Asked Questions
Can You Refuse a 5150 Hold?
No. If the legal criteria and probable cause exist, the hold is an involuntary hold; that is its purpose. A person can, however, refuse medical treatment in most non-emergency situations during the 72 hours, including the right to refuse medication, and they can request release, ask to be treated at a facility of their choice, and exercise every right in the advisement they receive [1]. People who refuse treatment after the hold ends cannot be forced into rehab by the 5150 itself.
What Evidence Is Needed for a 5250 Hold?
The facility must certify that the person, because of a mental disorder or impairment, remains a danger to self, a danger to others, or gravely disabled and has been unwilling or unable to accept voluntary treatment. That certification faces an informal hearing within four days, where family observations and a safety assessment can both matter, and a patient’s rights advocate helps the person prepare [3].
Does a 5150 Hold Show Up on a Background Check?
Standard employment background checks pull criminal records, and a 5150 is not a crime. The main formal consequence is the firearm prohibition noted above, which is reported to a state system [3]. Medical records from the hold stay protected by health privacy law.
Why Do People Use 5150 as Slang?
Because of the code’s visibility in California, 5150 crossed into pop culture decades ago as shorthand for someone acting erratically; Van Halen famously named an album and studio after it. In real usage, it is a legal designation for an emergency psychiatric hold, and using it as an insult adds stigma to what is, in plain language, a medical emergency.
Getting Help in Los Angeles After a Hold
A hold is 72 hours; recovery is longer, and the handoff between the two is where families have the most influence. If your loved one is coming off a 5150 or 5250 in Los Angeles County and needs detox, residential care, or treatment for co-occurring mental health conditions, you can contact Bright Paths Recovery for a confidential conversation about next steps, insurance verification, and same-week admission, or for a referral if a different level of care fits better.
