It shall be unlawful for any person to sell or offer for sale merchandise, except from a permanent structure which complies with all building ordinances and codes applicable to such structure at a fixed location on premises appropriately zoned for retail sales to which the seller has the right of occupancy by ownership, lease or signed permit. Goods may be displayed or merchandised from other than the primary-approved facility, so long as the goods remain on the premises of the primary-approved facility to which the seller has the right of occupancy and which is zoned for such sales. A person must have in his or her possession a special use permit as provided for in section 146-207 in order to deviate from the prohibition found in this section. A door-to-door salesperson must have in his or her possession a direct selling agent license, as provided for in section 86-226. (Code 1979, § 27-1)
