Cal. Welf. and Inst. Code § 10850.5
A county welfare department may, without the need to provide written documentation that consent has been obtained from a client, provide information to a housing authority created pursuant to Part 2 (commencing with Section 34200) of Division 24 of the Health and Safety Code, in order to aid the housing authority in the administration of that part. This section may be implemented either through an automated data exchange system or through a manual system. Any housing authority receiving and maintaining information pursuant to this section shall comply with confidentiality and privacy laws concerning the collection, maintenance, and dissemination of information, as contained in Section 10850 and the federal Privacy Act of 1974, contained in Section 552a of Title 5 of the United States Code. The county welfare department shall provide a written form to each person about whom information is to be provided to a housing authority pursuant to this section. The form shall notify the person that the information exchanges may occur. A copy of the form may be retained by the person and the county welfare department. The form shall specify the purpose for which the information has been solicited, the entities to which the information may be provided, the uses that may be made of the information, as set forth in Section 552a(e)(3) of Title 5 of the United States Code, and the right of the client to request review of the information that has been provided to the authority. The county welfare department may provide only information that is necessary to determine eligibility for housing authority programs or services for which the client has applied or which he or she is receiving. The county welfare department shall allow the client to review the information it has provided to a housing authority, upon request of the client. This section is not intended to eliminate any other legal obligation of the county welfare department to obtain consent from a client before releasing information to another entity.
