Wherever in the Jasper County Building Code (Chapter 15.05 JCC) or the Jasper County Unsafe Building Code it is provided that anything must be done to the approval of or subject to the direction of the Building Commissioner, or any other officer of the County, this shall be construed to give such officer only the discretion of determining whether the rules and standards established by ordinance have been complied with; and no such provisions shall be construed as giving any officer discretionary powers as to what such regulations or standards shall be, power to require conditions not prescribed by ordinance, or to enforce ordinance provisions in an arbitrary or discretionary manner. [Code 1988 § 171.05.]
