Any order either granting, denying, renewing or revoking any license under the provisions of this chapter may be appealed to the district court in the same manner as appeals from any order under the building or zoning ordinances of the City. Appeals from such orders must be taken within 10 days after the order is issued. Upon any such appeal the findings of fact of the Code Enforcement Director, if supported by substantial evidence, shall be conclusive. (Code 1981 § 25-57. Code 1995 § 98-104.)
