Cal. Financial Code - FIN § 7800. Section 7800.
Subject to the provisions of Section 2955.5 of the Civil Code, the board of directors of every association and affiliate or service corporation of an association shall establish standards for the maintenance of hazard insurance which are considered necessary to protect the institution’s interest in real estate security for its loans. The standards may include establishment of criteria based on such factors as recognized financial ratings of insurers and coverage forms, but those standards may not be based on the insurer’s corporate structure. Subject to compliance with these standards, an association, an affiliate or service corporation of an association
shall permit a borrower to have reasonable freedom of choice in selecting the insurer to provide hazard insurance coverage on the real estate security.
