A 5150 is California's legal process for temporarily detaining someone for psychiatric evaluation when specific safety criteria are met. It is not a criminal arrest. It is not a diagnosis. And it does not guarantee a full 72-hour hospital stay.
This article covers who qualifies for a hold, what actually happens during one, what families can do to help, and when to call for emergency support instead of waiting.
Key Takeaways
- A 5150 hold allows involuntary psychiatric detention for up to 72 hours for evaluation and crisis intervention.
- Criteria are danger to self, danger to others, or grave disability due to a mental health condition.
- Release can happen earlier than 72 hours, or the person may agree to voluntary care instead.
- Call 911 for immediate danger; contact 988 Suicide & Crisis Lifeline for urgent support without physical danger.
What Is a 5150 Involuntary Psychiatric Hold?
"5150" refers to California Welfare and Institutions Code Section 5150, the statute that authorizes temporary involuntary detention for assessment, evaluation, and crisis intervention. When probable cause exists that someone meets specific safety criteria, a peace officer, designated mental health professional, or mobile crisis team member can take that person into custody.
The purpose is evaluation, not punishment. A qualified clinician needs a safe setting to assess symptoms, immediate risk, medical needs, and the right level of care. That might mean transport to an emergency department, a psychiatric emergency service, a crisis stabilization unit, or another authorized receiving facility, depending on what's available locally.
A 5150 Is Not a Criminal Charge
A few distinctions matter here:
- Civil, not criminal. Law enforcement may assist with transport or safety, but this is a mental health intervention, not an arrest. The required notice states the person is not under criminal arrest.
- No permanent diagnosis. A hold does not lock in a label or trigger automatic long-term hospitalization.
- Can end early. The hold ends before 72 hours if clinicians find the criteria no longer apply, or the person agrees to voluntary treatment.
How the 72-Hour Clock Actually Works
"Up to 72 hours" is the maximum detention period. The clock starts at the moment of initial detention, not when the person arrives at a hospital.
A limited exception under WIC Section 5151 allows certain DHCS-certified facilities to exclude weekends and holidays from the count. That exception does not apply everywhere, so ask the facility whether it applies before assuming a release date.
What Are the Criteria for a 5150 Hold?
Authorized personnel can only detain someone when they determine, based on probable cause, that a mental health condition creates one of three specific safety risks. A diagnosis alone never satisfies this threshold. Behavior in context matters.
Danger to Self
Criteria focus on substantial risk of life-threatening injury. That can include suicidal thoughts paired with intent or a plan, a recent suicide attempt, serious self-harm, or similar conduct. Ordinary sadness or a difficult week don't meet this bar on their own.
Danger to Others
Credible threats, violent actions, or behavior creating a serious safety risk toward other people may qualify, but only when the conduct connects to the person's mental or behavioral health condition. A heated argument alone isn't enough.
Grave Disability
Grave disability traditionally means someone cannot, due to a qualifying condition, provide for basic needs like food, clothing, or shelter. SB 43 expanded that definition; it is effective statewide by January 1, 2026 at the latest, and counties could adopt it as early as January 1, 2024.
Under the updated WIC Section 5008, grave disability can also stem from a diagnosed severe substance use disorder. It now covers inability to secure personal safety or necessary medical care, not only food and shelter.
According to the California Department of Health Care Services' SB 43 FAQ, grave disability from a severe substance use disorder alone can support a 5150. Substance use without that defined inability still does not qualify.
Family input on history and available support can inform an assessment, but relatives do not make the final legal call. None of the following automatically justifies a hold:
- Having a mental illness diagnosis alone
- Refusing ordinary outpatient treatment
- Eccentric or unusual behavior without safety risk
- A family disagreement about treatment decisions
- Substance use that doesn't meet the severe-disorder threshold
How Does the 5150 Process Work in California?
The path from crisis to evaluation follows a set sequence, though county and facility procedures can differ.
Who Can Request Help
Peace officers, designated mental health professionals, emergency clinicians, and mobile crisis teams can initiate a hold based on probable cause. A family member cannot personally "issue" a 5150 — but they can call for help and provide critical information.
When requesting assistance, be specific. Share:
- Exact statements or actions that raised concern
- Access to weapons or medications
- Recent attempts, injuries, or self-harm
- Current substance use
- Existing diagnoses and medications
- Immediate environmental risks
Transport and Initial Evaluation
Once a responding team determines a hold is warranted, they transport the person to an authorized facility for medical screening and psychiatric assessment. Clinicians often need to rule out or address medical causes, intoxication, withdrawal, or injuries first.
Only after medical clearance does the psychiatric evaluation confirm whether the person still meets 5150 criteria.
Rights During the Hold
Involuntary detention limits freedom temporarily, but it doesn't eliminate rights. Under WIC Section 5325, people on a hold retain reasonable access to:
- A confidential phone to make calls
- Visitors, within facility rules
- An independent patient-rights advocate
Families often need to work through staff or an advocate because of privacy restrictions, even when they're deeply worried.
What Happens Next
| Outcome | What It Means |
|---|---|
| Release | Person no longer meets criteria; discharged with recommendations |
| Voluntary admission | Person agrees to continue treatment without further legal hold |
| 5250 certification | Additional involuntary treatment considered if criteria still apply |
A 5250 is a separate legal process allowing up to 14 days of certified treatment after the initial hold. It's not automatic. It requires new certification, a written notice, and a review hearing within four days under WIC Section 5256.
What Happens During and After a 5150 Hold?
While detained, the clinical team focuses on immediate safety: psychiatric symptoms, medical screening, medication review, stabilization, and determining the next level of care. The hold is an active assessment period, not passive waiting.
Discharge planning weighs several factors:
- Current risk level
- Ability to meet basic needs independently
- Engagement with treatment recommendations
- Housing and support system stability
- Medication needs and follow-up access
- Substance-use concerns
- Insurance or placement limitations
Discharge from a 5150 does not mean the underlying problem is solved. A responsible discharge plan should include:
- A written safety plan
- Clear medication instructions
- Follow-up appointments and crisis contacts
- Guidance on returning to emergency care if symptoms worsen
Continuing Care After Stabilization
Once someone stabilizes, options for continued support include outpatient therapy, intensive outpatient or partial hospitalization programs, residential care, and coordinated community services. A qualified professional should help select the right fit, not guesswork.
For families weighing those next steps, Alter Behavioral Health offers a continuum that includes residential treatment, partial hospitalization, intensive outpatient programs, crisis stabilization, and transitional support across Southern California locations, including Dana Point.
Clients typically meet with a psychiatrist or nurse practitioner within 24 hours of admission. A primary therapist then completes a full intake covering symptom severity, medication needs, crisis history, and home support.
A 5150 doesn't automatically lead to admission at any specific facility. If you're exploring next steps after a hold, Alter's admissions team can discuss eligibility, program availability, and insurance questions at (866) 248-9285.
How Can Families Support Someone During a Hold?
Watching a loved one go through a 5150 is hard. Here's what actually helps.
Share specific, factual information with clinicians:
- Timeline of behavior changes
- Direct threats or self-harm evidence
- Sleep changes and medication adherence
- Recent substance use
- Previous hospitalizations or medical conditions
- Known triggers
Communicate calmly:
- Validate distress without arguing about delusions
- Avoid promising a release date you can't control
- Ask what would help them feel safer
- Let clinical staff manage immediate safety decisions
Ask the facility about:
- The treatment plan and expected reassessment points
- How to reach a patient-rights advocate
- Visitation and communication rules
- Discharge criteria and follow-up resources
Most facilities, including Alter Behavioral Health, aim to contact family within 24 to 72 hours of admission, though how much information gets shared depends on what the patient is comfortable disclosing.
Protect your own safety too:
- Secure weapons and dangerous medications when appropriate
- Don't attempt to physically restrain or transport someone yourself
- Call 911 for immediate danger or 988 for urgent emotional support
A 5150 is a crisis intervention, not a complete treatment plan. Collaborative discharge planning and continued support after someone returns home matter just as much as the hold itself.
Frequently Asked Questions
What is a 5150 hold in California?
A 5150 is a California involuntary psychiatric hold allowing detention for up to 72 hours for evaluation and crisis intervention. It doesn't necessarily mean a full 72-hour hospital stay; release can happen sooner.
How long is an involuntary psych hold in California?
The initial hold lasts up to 72 hours from first detention. A person may be released earlier, agree to voluntary treatment, or face additional detention under a separate 5250 certification if criteria still apply.
What are the criteria for involuntary admission?
Qualified personnel must find probable cause of danger to self, danger to others, or grave disability from a mental health or qualifying behavioral health condition. A diagnosis alone never satisfies this standard.
What's the difference between 5150 and 5250?
A 5150 is the initial up-to-72-hour evaluation period. A 5250 is a separate, longer certification for up to 14 days of involuntary treatment, requiring new findings, notice, and generally a review hearing within four days.
Can you refuse a 5150 hold in California?
Generally, no. A person cannot simply refuse a lawfully authorized hold. They do retain rights to information, a patient advocate, review, and the option of accepting voluntary treatment instead.
What to do if someone is mentally unstable and won't get help?
Call 911 for immediate physical danger. For urgent emotional support without immediate danger, contact 988 or a local mobile crisis team. Share specific safety details with responders and avoid confrontation while waiting for help.
