3-1-9: INSPECTION OF PREMISES:
   A.   Whenever inspection of the premises used for or in connection with the operation of a licensed business is provided for or required by ordinance, or is reasonably necessary thereto, to secure compliance with any ordinance provision or to detect violations thereof, it shall be the duty of the licensee or the person in charge of the premises to be inspected to admit thereto, for the purpose of making the inspection, any officer or employee of the city who is authorized or directed to make such inspection at any reasonable time admission is requested.
   B.   Whenever an analysis of any commodity or material is reasonably necessary to secure conformance with any ordinance provision or to detect violations thereof, it shall be the duty of the licensee, whose business is governed by this provision to give any authorized officer or employee of the city requesting the same sufficient samples of such material or commodity for such analysis, upon request.
   C.   In addition to any other penalty which may be provided, the city council may revoke the license of any licensee who, by himself or by his agents, servants, employees or corporate officers, refuses to permit any such officer or employee, who is authorized to make such inspection or take such sample, to make the inspection or take an adequate sample of said material or commodity, or who interferes with such officer or employee while in the performance of his duty in making such inspection; provided, that no license shall be revoked for such cause unless written demand is made upon the licensee or person in charge of the premises. Such demand shall be made in the name of the city and state that such inspection or sample is desired at the time it is sought to make the inspection or to obtain the sample. (1970 Code §8-0.19)
