Cal. Health and Safety Code § 1275.1

(a) Notwithstanding any rules or regulations governing other health facilities, the regulations developed by the State Department of Health Care Services, or a predecessor, for psychiatric health facilities shall prevail. The regulations applying to psychiatric health facilities shall prescribe standards of adequacy, safety, and sanitation of the physical plant, of staffing with duly qualified licensed personnel, and of services based on the needs of the persons served thereby. (b) (1) The regulations shall include standards appropriate for treatment of three levels of disorder: (A) Involuntary ambulatory patients receiving treatment for a mental health disorder. (B) Voluntary ambulatory patients receiving treatment for a mental health disorder. (C) Involuntary ambulatory patients receiving treatment for a severe substance use disorder, as defined in subdivision (o) of Section 5008 of the Welfare and Institutions Code. (2) For purposes of this subdivision, “ambulatory patients” shall include, but not be limited to, persons who are deaf, blind, or have physical disabilities. Disoriented persons who are not bedridden or wheelchair users shall also be considered ambulatory patients. (c) The regulations shall not require, but may permit building and services requirements for hospitals which are only applicable to physical health care needs of patients that can be met in an affiliated hospital or in outpatient settings including, but not limited to, such requirements as surgical, dietary, laboratory, laundry, central supply, radiologic, and pharmacy. (d) The regulations shall include provisions for an “open planning” architectural concept. (e) The regulations shall exempt from seismic requirements all structures of Type V and of one-story construction. (f) Standards for involuntary patients shall include provisions to allow for restraint and seclusion of patients. These standards shall provide for adequate safeguards for patient safety and protection of patient rights.
