It is unlawful to sell, lease or finance any lot or parcel of real property, except for leases of agricultural land for agricultural purposes, or commence construction of any building for sale, lease or financing thereon, except for a model home, or allow occupancy thereof, for which a final tract map or final parcel map is required by this title until such map, in full compliance with the provisions of this title and the Map Act, has been filed for record by the county recorder. Nothing contained herein shall be deemed to prohibit an offer or contract to sell, lease or finance real property or to construct improvements thereon where such sale, lease, financing or the commencement of construction is expressly conditioned upon the approval and filing for recordation of a final tract map or final parcel map.
