SB 43 and What Changed About Gravely Disabled in California
A Guide to the Amended Standard and the Dates It Reached
Gravely disabled is the phrase that decides whether California's involuntary treatment provisions reach a person who is neither a danger to others nor a danger to themselves in the ordinary sense. Senate Bill 43 rewrote it, and the rewrite did two separate things: it widened what can cause the condition, and it widened what the condition is measured against.
The implementation is what made the change confusing to follow. The amendment did not arrive everywhere at once, because the statute itself let a county postpone it, and the outer limit for that postponement was January 1, 2026. Until a county implemented, the same facts could produce different answers in adjacent counties.
What follows sets out the amended text, the definitions the amendment added, the deferral provision and its end date, and who the statutes name as able to apply the standard. The scope of practice question for an LMFT is a separate one, and it is covered in the guide to what an LMFT can and cannot do in California.
SB 43 reached different counties on different dates, and it is one of several California changes that work that way. California Therapist Rules & Deadlines tracks dated changes and sunsets alongside the recurring deadlines of a California practice.

What Does Gravely Disabled Mean Now?
The operative text sits in Welfare and Institutions Code section 5008(h)(1)(A), and it applies to the articles governing 72-hour detention, certification for intensive treatment and conservatorship. It provides that gravely disabled means "A condition in which a person, as a result of a mental health disorder, a severe substance use disorder, or a co-occurring mental health disorder and a severe substance use disorder, is unable to provide for their basic personal needs for food, clothing, shelter, personal safety, or necessary medical care."
Two changes are contained in that sentence, and the Legislative Counsel's Digest for Senate Bill 43 describes both. It records that existing law "defines 'gravely disabled' as either a condition in which a person, as a result of a mental health disorder, is unable to provide for their basic personal needs for food, clothing, or shelter or has been found mentally incompetent, as specified," and that the bill "expands the definition of 'gravely disabled' to also include a condition in which a person, as a result of a severe substance use disorder, or a co-occurring mental health disorder and a severe substance use disorder, is, in addition to the basic personal needs described above, unable to provide for their personal safety or necessary medical care, as defined." The first change is to the cause, and the second is to the needs the standard measures.
Section 5008(h) carries two further limits that did not change and are easy to lose in discussion of what did. Paragraph (2) provides that for the certification and conservatorship articles, gravely disabled also includes a condition in which a person, as a result of impairment by chronic alcoholism, is unable to provide for the same basic personal needs. Paragraph (3) provides that the term "does not include persons with intellectual disabilities by reason of that disability alone."
What Do Personal Safety and Necessary Medical Care Mean?
Both terms are defined in the same section rather than left to ordinary usage, which matters because both could otherwise be read very broadly.
Section 5008(p) provides that personal safety "means the ability of one to survive safely in the community without involuntary detention or treatment pursuant to this part." The definition is framed against the intervention itself, in that it measures the ability to be safe in the community without the involuntary detention or treatment the part authorizes.
Section 5008(q) provides that necessary medical care "means care that a licensed health care practitioner, while operating within the scope of their practice, determines to be necessary to prevent serious deterioration of an existing physical medical condition that, if left untreated, is likely to result in serious bodily injury as defined in Section 15610.67." Three limits are built into that sentence. The condition has to be an existing physical medical condition rather than a risk of one, the determination belongs to a licensed practitioner acting within their own scope, and the threshold is serious bodily injury as another statute defines it.
What Is a Severe Substance Use Disorder for This Purpose?
Section 5008(o) ties the term to a diagnostic threshold: "Severe substance use disorder means a diagnosed substance-related disorder that meets the diagnostic criteria of 'severe' as defined in the most current version of the Diagnostic and Statistical Manual of Mental Disorders."
The definition does two things at once. It excludes substance use that does not meet the diagnostic criteria for a substance-related disorder at all, and within those that do, it excludes everything below the severe specifier. The reference is to the most current version of the manual rather than to a named edition, so the content of the standard moves when the manual does.
Why the Answer Depended on Which County You Were In
The deferral provision is in the statute itself. Section 5008(h)(4) provides that "A county, by adoption of a resolution of its governing body, may elect to defer implementation of the changes made to this section by Senate Bill 43 of the 2023-24 Regular Session of the Legislature until January 1, 2026."
The Department of Health Care Services describes the same rule in its guidance, stating that the legislation "permits a county, by adoption of a resolution of its governing body, to defer implementation ... until January 1, 2026 at the latest."
Two features of that provision sit behind the confusion it produced. The deferral required an affirmative act, a resolution adopted by the county's governing body, rather than happening by default. And the date is the end of the deferral rather than the start of the amendment, so a county that adopted no resolution was applying the amended standard from the point the amendment took effect.
January 1, 2026 is therefore the date on which the question of which definition applies stopped depending on geography. The Legislative Counsel's Digest describes the provision as one that "would authorize counties to defer implementation of these provisions to January 1, 2026, as specified," which is a deferral date rather than an effective date.
Who Applies This Standard?
The definition in section 5008 does not itself authorize anyone to do anything. The authority sits in section 5150 and the sections that follow it, and section 5150(a) names who may act: "a peace officer, professional person in charge of a facility designated by the county for evaluation and treatment, member of the attending staff, as defined by regulation, of a facility designated by the county for evaluation and treatment, designated members of a mobile crisis team, or professional person designated by the county."
That list is a list of roles rather than of licenses. A clinician who holds one of those roles is within it, and a clinician in private practice who holds none of them is not, whatever their license type.
Section 5150(b) adds a direction about how the determination is made. It provides that the individual making the determination "shall apply the provisions of Section 5150.05, and shall not be limited to consideration of the danger of imminent harm."
What This Means for Your Practice
For a clinician who holds none of the roles section 5150 names, the amendment changes the standard that others apply rather than anything the clinician may do. What the standard now reaches is a condition arising from a severe substance use disorder as well as from a mental health disorder, and an inability to provide for personal safety or necessary medical care as well as for food, clothing and shelter.
Both new terms are narrower in the statute than in ordinary use. Necessary medical care is tied to an existing physical medical condition, to a licensed practitioner's determination within their own scope, and to a serious bodily injury threshold, while personal safety is tied to survival in the community without the intervention itself.
Because the deferral ran county by county, material written about a county during its deferral describes the earlier standard rather than the current one.
A Closer Look at One Program: Sentio University's MFT Track
The following description of one specific MFT program is offered as a concrete example of how a program can prepare students for the legal and ethical demands of practice, not as a recommendation against evaluating other programs. Students should research multiple options and ask each one direct questions about how clinical skill is built and measured.
Sentio University, a nonprofit graduate school based in Los Angeles with a hybrid delivery model that serves students throughout California, offers a Master of Arts in Marriage and Family Therapy that meets the Board of Behavioral Sciences educational requirements for the LMFT. The program runs 20 months across 60 units at $1,120 per unit, with weekly online classes and one intensive in-person residency at the start of each semester, in cohorts capped at 24 students at a 4:1 student-to-faculty ratio. It is designed around deliberate practice methodology and is described in peer-reviewed work as the first graduate psychotherapy program to thoroughly integrate deliberate practice, with roughly half of nearly every class session dedicated to active skills training rather than lecture (Rousmaniere and Vaz, 2025, p. 2).
Crisis work is taught as a clinical skill rather than as a set of statutes to memorize. The 2026-2027 Academic Catalog places Trauma and Crisis Intervention (MFT545) in the second semester and Assessment and Diagnosis (MFT541) in the first, and students begin seeing clients at the Sentio Counseling Center during practicum, which provides more than 400 hours of supervised clinical experience during the degree. Because roughly half of nearly every class session is given to active skills training, the conversation a clinician has with a client in acute distress is one students rehearse under observation before they have it in a session.
Sentio is a small, newer institution, admits only applicants who are California residents or willing to relocate to California and who intend to license in California, and its alumni network is still developing. Prospective students weighing Sentio alongside larger or older programs should factor that into their decision. Learn more at the Sentio MFT program overview, the tuition and fees page, and the Sentio FAQ page.
Making Your Decision
Read section 5008 rather than a summary of it, since the three definitions that carry the change sit in three different subdivisions. Note that a county's own implementation date is what decides which standard applied there before January 1, 2026. Note that section 5150 names roles rather than license types, and that a clinician who holds none of them is outside the section. If you are still choosing a graduate program, ask how crisis work is taught, whether students practice the conversation rather than only reading about the law, and what supervision looks like when a client presents in crisis for the first time. Program websites describe clinical training in similar language regardless of what is actually happening in classrooms and supervision rooms. Ask every program you are seriously considering whether you can attend a live or online class session before enrolling, and ask to speak with current students and recent graduates about how supervision and skill development function in practice. Reputable programs should welcome the request. Hesitation or refusal is informative on its own. Trust what you see in a classroom over what you read in promotional copy.
Frequently Asked Questions
What does gravely disabled mean in California now?
Welfare and Institutions Code section 5008(h)(1)(A) defines it as a condition in which a person, as a result of a mental health disorder, a severe substance use disorder, or a co-occurring mental health disorder and a severe substance use disorder, is unable to provide for their basic personal needs for food, clothing, shelter, personal safety, or necessary medical care.
What did SB 43 add to the definition?
Two things. The condition may now arise from a severe substance use disorder on its own or co-occurring with a mental health disorder, where the earlier text reached a mental health disorder. And the needs the standard measures now include personal safety and necessary medical care alongside food, clothing and shelter.
What is a severe substance use disorder for this purpose?
Section 5008(o) defines it as a diagnosed substance-related disorder that meets the diagnostic criteria of severe as defined in the most current version of the Diagnostic and Statistical Manual of Mental Disorders. The statute ties the term to a diagnostic threshold rather than to a description of behavior.
What do personal safety and necessary medical care mean?
Section 5008(p) defines personal safety as the ability of one to survive safely in the community without involuntary detention or treatment under the part. Section 5008(q) defines necessary medical care as care that a licensed health care practitioner, operating within the scope of their practice, determines to be necessary to prevent serious deterioration of an existing physical medical condition that, if left untreated, is likely to result in serious bodily injury.
Why did the answer depend on which California county you were in?
Section 5008(h)(4) provides that a county, by adoption of a resolution of its governing body, may elect to defer implementation of the changes made by Senate Bill 43 of the 2023-24 Regular Session until January 1, 2026. Counties that adopted such a resolution applied the earlier definition until they implemented, and January 1, 2026 was the outer limit.
Does the amended definition reach someone with an intellectual disability?
Not by reason of that alone. Section 5008(h)(3) provides that the term gravely disabled does not include persons with intellectual disabilities by reason of that disability alone.
Who can place a person on a 72-hour hold in California?
Section 5150(a) names a peace officer, the professional person in charge of a facility designated by the county for evaluation and treatment, a member of the attending staff of such a facility as defined by regulation, designated members of a mobile crisis team, and a professional person designated by the county. A therapist who does not hold one of those roles is not among them.
Does the standard require imminent harm?
The statute does not put it in those terms. Section 5150(b) provides that when determining if a person should be taken into custody, the individual making that determination shall apply the provisions of section 5150.05 and shall not be limited to consideration of the danger of imminent harm.
