Contact Planning & Zoning at 712-792-9973 for review and inspection arrangements; the reviewed county materials do not publish a separate inspection-booking URL or sequence.
Which codes and exemptions should I review?
Carroll County Ordinance No. 14 zoning regulations, including district use and setback rules, airport-airspace review, floodplain and site-plan requirements, plus applicable Iowa state building, electrical, plumbing, mechanical, and energy requirements. The reviewed county materials do not identify a specific 2026 model technical building-code edition. All buildings require either a building permit or an agricultural exemption. No permit is required for interior-only remodeling when exterior dimensions are unchanged, or for a structure under 100 square feet in the A-1 Agricultural District, but setbacks still apply. Farm land, farm houses, farm barns, farm outbuildings, and other structures primarily adapted for agricultural use have no permit fee while so used, but the county requires a Certificate of Exemption and other overlays such as airport airspace or floodplain rules may still apply.
