Iowa Code Title III. Public Services and Regulation [Chs. 80-122C] § 89A.15. Inspections by local authorities

A city or other governmental subdivision shall not make or maintain any ordinance, bylaw, or resolution providing for the licensing of special inspectors. An ordinance or resolution relating to the inspection, construction, installation, alteration, maintenance, or operation of conveyances within the limits of the city or governmental subdivision which conflicts with this chapter or with rules adopted pursuant to this chapter is void. The director, in the director's discretion, may accept inspections by local authorities in lieu of inspections required by section 89A.6, but only upon a showing by the local authority that applicable laws and rules will be consistently and literally enforced and that inspections will be performed by special inspectors.
