California does not have a Baker Act. The Baker Act is Florida’s law; California’s equivalent is the 5150 hold, a 72-hour involuntary psychiatric detention authorized under Section 5150 of the California Welfare and Institutions Code. It lets designated professionals and law enforcement detain someone in a mental health crisis for evaluation and short-term treatment when that person is a danger to themselves, a danger to others, or gravely disabled. A 5150 is a civil process, not a criminal arrest, and it operates under the Lanterman-Petris-Short Act, which pairs crisis intervention with due process protections at each stage.1California Legislative Information.

Who Qualifies for a 5150 Hold
A 5150 requires probable cause that the person, as a result of a mental health disorder, meets at least one of three criteria: danger to self, danger to others, or gravely disabled.1California Legislative Information. California Welfare and Institutions Code 5150 – Detention of Persons With a Mental Health Condition for Evaluation and Treatment The “as a result of a mental health disorder” language matters. Someone who is dangerous purely because of intoxication, or distressed for reasons unrelated to a mental health condition, does not automatically meet the standard, though co-occurring substance use and mental health conditions are covered.
Danger to self and danger to others both require specific, observable facts rather than speculation. A described plan to attempt suicide by a specific method usually meets the threshold. A vague expression of unhappiness usually does not. Whoever initiates the hold must document those observations in writing.
The third criterion, gravely disabled, has a precise statutory definition that SB 43 recently broadened. A person is gravely disabled when, because of a mental health disorder, a severe substance use disorder, or both, they cannot provide for their basic personal needs for food, clothing, shelter, personal safety, or necessary medical care.2California Legislative Information. California Welfare and Institutions Code 5008 – Definitions Personal safety and necessary medical care are the newer additions. Personal safety refers to the ability to survive safely in the community without involuntary detention. Necessary medical care refers to treatment a licensed practitioner determines is needed to prevent serious deterioration of a physical condition that could cause serious bodily injury if untreated.3California Department of Health Care Services. Senate Bill 43 Changes to Gravely Disabled Behavioral Health FAQs Symptoms alone are not enough. The test is functional inability to meet basic needs.
Who Can Initiate a 5150
Only certain people have the legal authority to place someone on a 5150. The statute names peace officers, the professional person in charge of a county-designated evaluation facility, attending staff at such a facility, designated members of a mobile crisis team, and other professionals specifically designated by the county.1California Legislative Information. California Welfare and Institutions Code 5150 – Detention of Persons With a Mental Health Condition for Evaluation and Treatment Family members, friends, and coworkers cannot.
If you are worried about someone in crisis, your options are calling 911, contacting the county’s mobile crisis team, or reaching the county behavioral health department’s crisis line. Mobile crisis teams send mental health clinicians, sometimes alongside law enforcement rather than instead of it, and many counties operate them around the clock. Describe specific behaviors when you call. Concrete observations help the responding team decide whether the criteria are met.
What Happens During the 72 Hours
Once a 5150 begins, the person is transported to a county-designated psychiatric facility. The 72-hour clock starts at the time of initial detention, not at facility arrival.1California Legislative Information. California Welfare and Institutions Code 5150 – Detention of Persons With a Mental Health Condition for Evaluation and Treatment Some counties exclude weekends and holidays from the calculation, which can extend the calendar length of the stay.
At the facility, mental health professionals conduct a full psychiatric evaluation, which may involve medication. The facility is not required to hold anyone for the full 72 hours. The treating psychiatrist must release the person sooner if personal observation shows they no longer need evaluation or treatment.4California Legislative Information. California Welfare and Institutions Code 5152 Most 5150 holds end this way, with release or a shift to voluntary status well before the deadline.
When the 72 hours expire, one of three outcomes follows. The person is released. The person agrees to remain voluntarily. Or the facility files for a 14-day extension under WIC 5250 because the criteria are still met and voluntary treatment has been refused.5California Legislative Information.

Your Rights While Detained
A 5150 is not a criminal arrest, and the person detained keeps significant legal rights. Notification happens in two stages.
At the moment of detention, whoever takes custody must orally advise the person that they are not under arrest and are being taken to a named facility for a mental health examination. If the detention happens at the person’s home, they must also be told they can bring personal items, make a phone call, and leave a note for family or friends.1California Legislative Information. California Welfare and Institutions Code 5150 – Detention of Persons With a Mental Health Condition for Evaluation and Treatment
At the facility, the person receives oral and written notice covering the reasons for the hold, the factual basis, its expected duration, and the right to request a different facility or treating professional. The notice also explains that if the hold is extended beyond 72 hours, the patient has the right to a lawyer, a qualified interpreter, and a hearing before a judge, with counsel provided free if the patient cannot afford one.1California Legislative Information. California Welfare and Institutions Code 5150 – Detention of Persons With a Mental Health Condition for Evaluation and Treatment
Refusing Medication
Patients on a 5150 have the right to refuse antipsychotic medication. When a patient refuses, the treatment team must first consider alternatives. If alternatives are unlikely to work, the facility cannot simply override the refusal. It must petition for a capacity hearing to decide whether the patient lacks the capacity to make that treatment decision.6California Legislative Information. California Welfare and Institutions Code 5332
There is one exception. In a genuine emergency where immediate intervention is needed to prevent serious harm, antipsychotic medication can be given over objection before any hearing. Even then, the medication must be limited to what the emergency requires and provided in the least restrictive manner possible.6California Legislative Information. California Welfare and Institutions Code 5332
What Happens If the Hold Is Extended
If the 5150 does not end in release or voluntary status, the process can escalate through longer detention periods, each with its own justification.
The first step is a 14-day intensive treatment certification under WIC 5250. Professional staff must certify that the person still meets one of the three criteria and has refused or is unable to accept voluntary treatment.5California Legislative Information. California Welfare and Institutions Code 5250 – Certification for Intensive Treatment A certification review hearing follows automatically within four days unless the patient requests formal judicial review instead. The facility carries the burden of showing probable cause for continued detention, and an attorney or advocate visits the patient beforehand to help prepare.7California Legislative Information. California Welfare and Institutions Code 5254
Additional holds exist beyond the 14 days. WIC 5260 allows a second 14-day period for someone who remains a danger to others. WIC 5270.15 authorizes a 180-day post-certification hold for individuals found imminently dangerous, with full due process protections. For people who remain gravely disabled, the path leads to LPS conservatorship under WIC 5350, where a court appoints a conservator to make treatment and placement decisions; the proposed conservatee can demand a court or jury trial on whether they are gravely disabled.8California Legislative Information. California Welfare and Institutions Code 5350 Each step requires fresh justification. A facility cannot extend a hold simply because the original criteria were once met.
Firearm Restrictions After a 5150
A 5150 hold triggers a five-year prohibition on owning, possessing, or purchasing firearms, other deadly weapons, and ammunition. The ban applies to anyone taken into custody under Section 5150 as a danger to self or others, assessed under Section 5151, and admitted to a designated facility. The facility must inform the patient of this restriction before or at the time of discharge.9California Legislative Information. California Welfare and Institutions Code 8103
Repeat holds carry heavier consequences. A person detained, assessed, and admitted on a 5150 more than once within a one-year period faces a lifetime firearm prohibition rather than the five-year one.9California Legislative Information. California Welfare and Institutions Code 8103
Federal law under 18 U.S.C. ยง 922(g)(4) separately bars anyone “committed to a mental institution” from possessing firearms.10Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Whether a 72-hour 5150 qualifies as a commitment under federal law is not uniformly resolved and can depend on the facts. The California five-year ban is unambiguous and applies to every qualifying 5150 admission regardless of how the federal question is resolved.
Background Checks and Records
A 5150 is a civil detention, not a criminal arrest. It does not create a criminal record and will not appear on a standard employment background check. Most employers running a LiveScan or similar screening will never see it.
Firearm screening is the significant exception. The California Department of Justice keeps records of 5150 holds for gun purchase and permit applications, so the five-year or lifetime prohibition surfaces when you apply to buy a firearm or seek a concealed carry license. Certain high-security law enforcement or government positions may involve deeper background investigations that reach mental health records.
Because a 5150 is treated as a medical record rather than a criminal one, healthcare confidentiality rules apply. Providers generally cannot disclose the hold to employers, landlords, or other third parties without the patient’s consent, with narrow safety and legal exceptions.
Who Pays for a 5150 Hold
Involuntary psychiatric holds can produce substantial facility charges, and lack of consent to treatment does not eliminate financial responsibility on its own.
If the person has private insurance, the facility is generally expected to bill the insurer. If the person qualifies for Medi-Cal, the hold may be covered through the county behavioral health system. Many counties run programs that cover 5150 costs for uninsured or lower-income patients, and retroactive Medi-Cal enrollment is sometimes possible after the fact. Contacting the county behavioral health department after discharge is usually the best first step for sorting out billing and identifying assistance.
There is no blanket rule that involuntary holds are free. Costs vary with facility, length of stay, and insurance status. If a bill looks wrong, the county Patients’ Rights Advocate, whose contact information must be provided at admission, can help work through the dispute.
