Call ahead because the administrator is frequently in the field.
Which codes and exemptions should I review?
Butler County Zoning Ordinance No. 28 (adopted July 18, 2023), including county zoning certificates, setbacks, land-use controls, site-plan review, and floodplain 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. Qualifying agricultural land, farm houses, farm barns, farm outbuildings, and other structures primarily adapted for agricultural purposes are exempt from county zoning while so used under Iowa Code section 335.2, but the applicant must attach the county agricultural-exemption application to the building-permit application and demonstrate the agricultural principal use. Floodplain structures remain regulated, and a use change can end the exemption. No broad minor/cosmetic exemption list was published.
