Cal. Bus. & Prof. Code § 11022

(a) It is unlawful for an owner, subdivider, agent or employee of a subdivision or other person, with intent directly or indirectly to sell or lease subdivided lands or lots or parcels therein, to authorize, use, direct, or aid in the publication, distribution, or circularization of an advertisement, radio broadcast, or telecast concerning subdivided lands, that contains a statement, pictorial representation, or sketch that is false or misleading.
(b) An owner, subdivider, agent, or employee of an owner or subdivider may, prior to the use, publication, distribution, or circulation of any advertisement concerning subdivided lands, submit the same to the department for approval. The submission shall be accompanied by a fee of two hundred dollars ($200). The commissioner may prescribe by regulation the amount of the fee, not to exceed two hundred sixty dollars ($260).
If disapproval of the proposed advertisement is not communicated by the department to the owner, subdivider, agent, or employee within 15 calendar days after receipt of the copy of the proposed advertisement, the advertisement shall be deemed approved, but the department shall not be estopped from disapproving a later distribution, circulation, or use of the same or similar advertising.
(c) Nothing in this section shall be construed to hold the publisher or employee of any newspaper, or any job printer, or any broadcaster, or telecaster, or any magazine publisher, or any of the employees thereof, liable for any publication herein referred to unless the publisher, employee, or printer has actual knowledge of the falsity thereof or has an interest either as an owner or agent in the subdivided lands so advertised.
