California Code, Civil Code - CIV § 1785.20.5

(a) Prior to requesting a consumer credit report for employment purposes, the user of the report shall provide written notice to the person involved.  The notice shall inform the person that a report will be used, and shall identify the specific basis under subdivision (a) of Section 1024.5 of the Labor Code for use of the report.  The notice shall also inform the person of the source of the report, and shall contain a box that the person may check off to receive a copy of the credit report.  If the consumer indicates that he or she wishes to receive a copy of the report, the user shall request that a copy be provided to the person when the user requests its copy from the credit reporting agency.  The report to the user and to the subject person shall be provided contemporaneously and at no charge to the subject person.

(b) Whenever employment involving a consumer is denied either wholly or partly because of information contained in a consumer credit report from a consumer credit reporting agency, the user of the consumer credit report shall so advise the consumer against whom the adverse action has been taken and supply the name and address or addresses of the consumer credit reporting agency making the report.  No person shall be held liable for any violation of this section if he or she shows by a preponderance of the evidence that, at the time of the alleged violation, he or she maintained reasonable procedures to assure compliance with this section.
