Cal. FIN § 22154

(a) Subject to Section 22157.1, a licensee shall not conduct the business of making loans or administering a PACE program under this division within any office, room, or place of business in which any other business is solicited or engaged in, or in association or conjunction therewith, except as is authorized in writing by the commissioner upon the commissioner’s finding that the character of the other business is such that the granting of the authority would not facilitate evasions of this division or of the rules and regulations made pursuant to this division. An authorization, once granted, remains in effect until revoked by the commissioner. The commissioner may authorize the other business through the Nationwide Mortgage Licensing System and Registry.

(1) The activity is not prohibited by, or in violation of, the laws applicable to the affiliate or supervised financial institution.

(2) The products and services are not offered and sold in a manner that restricts the ability of the borrower or customer to individually select or reject a product or service that is offered.

(1) “Affiliated” or “affiliate” means the following: A corporation is an affiliate of, or a corporation is affiliated with, another specified corporation if it directly, or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with, the other specified corporation.
