Cass County, Iowa Plumbing Permit Requirements
In Cass County, Iowa, building permits are required for anyone planning to build, rebuild, alter, enlarge, or move any building or structure on their property. This includes plumbing work. The Cass County Zoning department is responsible for zoning in the rural areas of the county. For properties in unincorporated areas, the Cass County Zoning Ordinance applies.

If a new acreage does not have an E-911 address, a new address application is required.
Iowa has adopted the Uniform Plumbing Code (UPC) as its state plumbing code, with the most recent adoption being the 2024 UPC. Local jurisdictions may not adopt other plumbing codes but can implement stricter amendments to the state code, provided these local amendments are submitted to the state board. The state plumbing code applies to plumbing in buildings or on premises within cities and to those outside city limits if they are connected to a municipal water distribution or wastewater collection system. Local ordinances may impose higher, but not lower, plumbing standards than the state code.
Rules for Properties in Unincorporated Areas
The Cass County Zoning Ordinance specifically applies to all unincorporated territory within Cass County, Iowa. This ordinance sets forth regulations for land use and building. While the ordinance generally exempts agricultural land, farmhouses, barns, and outbuildings from its regulations when primarily used for agricultural purposes, any construction, building, dam, deposit, or excavation within floodplains applies to both agricultural and non-agricultural lands. For any construction or alteration of buildings or structures in unincorporated areas, residents are required to complete an Application for Building Permit.
