California Code, Welfare and Institutions Code - WIC § 10850.9

(a)(1) Notwithstanding Section 10850, an authorized employee of a county social services department may disclose the name, residential address, telephone number, and email address of elderly or disabled individuals receiving services to police, fire, paramedical personnel, or other designated emergency services personnel, in the event of a public safety emergency that necessitates the possible evacuation of the area in which those elderly or disabled clients reside. Those public safety emergencies include, but are not limited to, fires, earthquakes, gas leaks, bomb scares, public safety power shutoffs, and other natural or human-made occurrences that jeopardize the immediate physical safety of county residents.

(2) If a county social services agency intends to disclose information pursuant to paragraph (1), it shall notify elderly or disabled individuals receiving services, at the time the individual is enrolled in services or at the time of the agency's next contact with the individual, whichever comes first, of that fact. Beginning on January 1, 2022, the individual shall have the option to opt out of having their name, residential address, telephone number, and email address disclosed as described in paragraph (1).
