No permittee or manager of a massage establishment shall permit any person under the age of eighteen (18) years to come or remain on the premises of any massage establishment, as masseur, employee or patron, or otherwise, unless such person is on the premises on lawful business. Notwithstanding the foregoing provision, in the event more than one business is operated on the same business premises, the massage establishment on the premises must be maintained and operated separate from all other businesses on the premises and shall be separated by permanent walls or other structures which clearly delineate the massage establishment from other businesses on the premises. (Ord. 1414 § 1 (part), 1996: prior code § 7-6-15)
