Cal. Welf. & Inst. Code § 5150

(a) When a person, as a result of a mental health disorder, is a danger to others, or to themselves, or gravely disabled, 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 may, upon probable cause, take, or cause to be taken, the person into custody for a period of up to 72 hours for assessment, evaluation, and crisis intervention, or placement for evaluation and treatment in a facility designated by the county for evaluation and treatment and approved by the State Department of Health Care Services. The 72-hour period begins at the time when the person is first detained. At a minimum, assessment, as defined in Section 5150.4, and evaluation, as defined in subdivision (a) of Section 5008, shall be conducted and provided on an ongoing basis. Crisis intervention, as defined in subdivision (e) of Section 5008, may be provided concurrently with assessment, evaluation, or any other service.
(b) When determining if a person should be taken into custody pursuant to subdivision (a), 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.
(c) The professional person in charge of a facility designated by the county for evaluation and treatment, member of the attending staff, or professional person designated by the county shall assess the person to determine whether the person can be properly served without being detained. If, in the judgment of the professional person in charge of the facility designated by the county for evaluation and treatment, member of the attending staff, or professional person designated by the county, the person can be properly served without being detained, the person shall be provided evaluation, crisis intervention, or other inpatient or outpatient services on a voluntary basis. This subdivision does not prevent a peace officer from delivering an individual to a designated facility for assessment under this section. Furthermore, the assessment requirement of this subdivision does not require a peace officer to perform any additional duties other than those specified in Sections 5150.1 and 5150.2.
(d) If a person is evaluated by a professional person in charge of a facility designated by the county for evaluation or treatment, member of the attending staff, or professional person designated by the county and is found to be in need of mental health services, but is not admitted to the facility, all available alternative services provided pursuant to subdivision (c) shall be offered, as determined by the county mental health director.
(e) If, in the judgment of the professional person in charge of the facility designated by the county for evaluation and treatment, member of the attending staff, or the professional person designated by the county, the person cannot be properly served without being detained, the admitting facility shall require an application in writing stating the circumstances under which the person’s condition was called to the attention of the peace officer, professional person in charge of the facility designated by the county for evaluation and treatment, member of the attending staff, or professional person designated by the county, and stating that the peace officer, professional person in charge of the facility designated by the county for evaluation and treatment, member of the attending staff, or professional person designated by the county has probable cause to believe that the person is, as a result of a mental health disorder, a danger to others, or to themselves, or gravely disabled. The application shall also record whether the historical course of the person’s mental disorder was considered in the determination, pursuant to Section 5150.05. If the probable cause is based on the statement of a person other than the peace officer, professional person in charge of the facility designated by the county for evaluation and treatment, member of the attending staff, or professional person designated by the county, the person shall be liable in a civil action for intentionally giving a statement that the person knows to be false. A copy of the application shall be treated as the original.
(f) At the time a person is taken into custody for evaluation, or within a reasonable time thereafter, unless a responsible relative or the guardian or conservator of the person is in possession of the person’s personal property, the person taking them into custody shall take reasonable precautions to preserve and safeguard the personal property in the possession of or on the premises occupied by the person. The person taking them into custody shall then furnish to the court a report generally describing the person’s property so preserved and safeguarded and its disposition, in substantially the form set forth in Section 5211, except that if a responsible relative or the guardian or conservator of the person is in possession of the person’s property, the report shall include only the name of the relative or guardian or conservator and the location of the property, whereupon responsibility of the person taking them into custody for that property shall terminate. As used in this section, “responsible relative” includes the spouse, parent, adult child, domestic partner, grandparent, grandchild, or adult brother or sister of the person.
