In Barrett v. Hammer Builders, Inc. (1961) 195 Cal.App.2d 305, the defendants (subdividers) submitted an application for a public report which described the type of buildings that would be constructed on the lots and stated that the lots would be sold by grant deeds. After the issuance of the public report, the defendants, without notifying the Real Estate Commissioner, constructed a different type of building on the lots and sold the lots by sales contracts. Plaintiff, a lot purchaser, brought an action to rescind his purchase. The court ruled in plaintiff's favor on the ground that defendants had violated Business and Professions Code section 11012 stating: " Section 11012 of the Business and Professions Code requires the subdivider to notify the commissioner of any changes in the offering. It is clear that the legislative purpose of protecting the public would not be effectuated by permitting a subdivider to circumvent the legislative mandate." ( Id., at p. 310.)
