California 1799 Hold: Rules, Rights, and 5150 Conversion

A California 1799 hold is a short-term involuntary detention under Health and Safety Code Section 1799.111 that lets a hospital not designated for psychiatric evaluation keep a person in mental health crisis for up to 24 hours while staff work to find an appropriate psychiatric placement.¹ It exists to cover a specific gap: a general emergency room is not authorized to run a full 5150 evaluation, but it also cannot safely release someone who appears dangerous or gravely disabled. The 1799 hold buys time to arrange a transfer.

1799 Hold vs. 5150 Hold

The clearest way to understand a 1799 hold is to see what makes it different from the 72-hour 5150 that most people have heard of.

Location is the first difference. A 5150 happens at a facility the county has specifically designated for involuntary psychiatric evaluation and treatment. A 1799 hold happens at a hospital that lacks that designation, usually a general acute care hospital or a non-designated acute psychiatric hospital where the person arrived or was brought for emergency care.¹ If you walked into a regular ER, you are almost certainly looking at a 1799. If you were taken directly to a county-designated psychiatric facility, the 5150 framework applies instead.²

Duration is the second. A 5150 authorizes up to 72 hours; a 1799 caps at 24.

Who can authorize it is the third. A 5150 can be initiated by peace officers, mobile crisis team members, or designated county professionals. A 1799 hold requires the opinion of the treating physician or a clinical psychologist with specific medical staff privileges at the hospital.¹

When a 1799 Hold Is Lawful

Four conditions must all be present for the detention to hold up legally. Miss one, and the legal basis collapses.

A treating physician or qualified clinical psychologist has determined that, because of a mental health disorder, the person is dangerous to themselves, dangerous to others, or gravely disabled. “Gravely disabled” means the person cannot provide for their own food, clothing, or shelter.
Hospital staff are making repeated, documented attempts to find appropriate mental health treatment elsewhere, starting as soon as the physician determines the person is medically stable enough for transfer.
The detention does not exceed 24 hours.
Probable cause supports the detention.

These criteria come straight from subdivision (a) of the statute.¹ The documentation piece is where hospitals most often stumble. One phone call to one facility does not satisfy the law. The statute expects ongoing outreach and a paper trail that proves it.

The Eight-Hour Checkpoint

If the hold runs past eight hours, two more conditions apply. The delay must be because the person needs continuous care, observation, or treatment that the hospital is currently providing. And a physician or qualified clinical psychologist must re-evaluate the person and confirm they still meet the danger or grave disability standard.¹ This matters. It stops a hospital from starting a 1799 and just running out the clock without checking whether the person has stabilized. If the crisis has passed, the hold should end.

What Happens During the 24 Hours

A 1799 hold is not meant as a treatment period the way a 5150 is. The point is to keep you safe while the hospital actively works to locate a psychiatric bed. You receive whatever medical care you need, including stabilization, and the hospital contacts county-designated facilities, psychiatric hospitals, and crisis stabilization units trying to arrange a transfer.

Three things can end the hold. The hospital finds placement and you are transferred to a designated facility, where a 5150 evaluation can begin. You stabilize and no longer meet the danger or grave disability criteria, and a physician or qualified clinical psychologist authorizes release. Or the 24 hours simply run out.

When a clinical psychologist, rather than a physician, makes the release call, the psychologist must consult first with the treating physician, and both clinicians must document their findings in the medical record.¹

If the Hold Converts to a 5150

Many 1799 holds end with a transfer to a county-designated facility, where the 5150 process begins. The underlying criteria are the same for both: danger to self, danger to others, or grave disability due to a mental health disorder.²

One detail that often gets missed, and that works in your favor: time spent on a 1799 hold counts toward the 72 hours of a subsequent 5150. If you spent 18 hours on a 1799 at a general hospital before transfer, the designated facility can only hold you another 54 hours, not a fresh 72.¹ The law does not allow hospitals to stack holds back-to-back.

Your Rights While on a 1799 Hold

California guarantees broad rights to people detained for mental health reasons. These include dignity and privacy, prompt medical care, freedom from unnecessary restraint or excessive medication, and protection from abuse or neglect.³ Medication cannot be used as punishment or for staff convenience.

Refusing Medication

You can refuse treatment with medications, including antipsychotic drugs, unless the situation is a genuine emergency requiring immediate action to preserve life or prevent serious bodily harm. Outside of an emergency, a hospital that wants to medicate you over your objection must first get a court order or a capacity finding from what is sometimes called a Riese hearing.⁴ Within the 24-hour window of a 1799 hold, actually obtaining a capacity hearing is rare. That makes the right to refuse medication practically significant during these holds.

Patient’s Rights Advocate

You can see a patient’s rights advocate who has no involvement in your treatment, and you can contact that advocate at any time during the hold. The facility is required to help you exercise this right.⁴ You can also communicate privately with that advocate or with an attorney. Contact with family or other support people is generally allowed, subject to reasonable safety restrictions.

Firearm Consequences

This is where the 1799 versus 5150 distinction has lasting consequences for gun owners. California’s firearm prohibition for mental health detentions, in Welfare and Institutions Code Section 8103, applies to a person who has been taken into custody under Section 5150, assessed, and admitted to a designated facility. All three steps have to happen. That triggers a five-year ban on owning, possessing, or purchasing firearms. A second qualifying admission within a year triggers a lifetime ban.⁵

Section 8103 does not reference Section 1799.111. A 1799 hold on its own, where you are detained at a non-designated hospital and released without ever being placed on a 5150, does not appear to trigger the firearm prohibition. If your 1799 converts to a 5150 and you are then admitted to a designated facility, the five-year ban applies. For anyone who owns firearms, knowing exactly which hold you were on, and whether you were formally admitted, is worth tracking.

Challenging a 1799 Hold

The 24-hour cap makes real-time legal challenges hard. Courts rarely move that fast. But remedies exist both during and after.

During the hold, you can seek a writ of habeas corpus asking a court to order the facility to justify the detention. If the court finds the hold lacks a legal basis, it can order your release. Getting an attorney or patient’s rights advocate involved quickly is the realistic way to make this happen inside the window.

After the hold, civil litigation is the main path. Possible claims include false imprisonment where the hold lacked probable cause or ran past the statutory limits, medical malpractice where the evaluation fell below accepted standards, and civil rights violations where constitutional protections were disregarded. Damages can cover emotional distress, lost wages, and other financial harm from the improper detention.

The strongest challenges tend to focus on whether the statutory criteria were actually met. If the authorizing physician did not conduct an adequate assessment, if the hold ran past eight hours without the required re-evaluation, or if the hospital failed to document its placement efforts, the immunity the statute provides to the hospital may not protect it.¹ Testimony from an independent psychiatrist or psychologist is often central to arguing that the initial assessment was inadequate or that you never actually met the danger or grave disability standard.
