Cass County Zoning and Planning Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?

How are inspections scheduled?
Submit the Application for Building Permit through the county forms page or obtain it from the Administrative Officer. The ordinance requires an Occupancy Compliance Certificate before most non-single-family-dwelling occupancy or changes in occupancy. Routine building-inspection scheduling instructions were not published; contact Zoning Administrator Mike Kennon at 712-254-1500. Subdivision improvements are inspected by the county before approval.
Which codes and exemptions should I review?
Cass County Zoning & Subdivision Ordinance, adopted 1962 and updated 1982 and 2003, as included in the county code updated October 6, 2025; requirements include rural zoning districts, setbacks, land use, occupancy compliance, subdivision controls, airport-airspace rules, and floodplain standards, 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. Agricultural land, farmhouses, farm barns, farm outbuildings, and other structures primarily adapted for agricultural use are outside the county zoning requirements while so used, but floodplain regulations apply equally to agricultural and nonagricultural development. The ordinance requires a permit for structures erected, reconstructed, structurally altered to increase exterior dimensions/height/floor area or dwelling units, or changed in use. No broad minor/cosmetic exemption list was published.
