Cal. Health & Safety Code § 123895

The designated agency shall determine the financial eligibility of the family according to standards established by the department. The agency will also determine if the parents are residents of the county, if the guardian of the child is a resident of the county, or if the emancipated minor is a resident of the county where application for services is made. If the agency finds that the family, guardian, or emancipated minor is a resident of the county and financially eligible for services, it shall make a record of the facts and shall certify this child for care under the program.
