A bill for an act relating to county zoning ordinances governing residential buildings.

This bill (SF 2442) limits county zoning boards' authority over residential construction in unincorporated areas. It prohibits counties from restricting the building or development of residential properties - defined as single-family homes, townhouses, and small apartment buildings (up to 12 units per building) - except for regulations necessary to protect life or property safety. Counties may no longer impose rules on residential construction for non-safety reasons, such as limiting building density or lot coverage. The law directly affects homeowners, developers, and county zoning boards in rural and unincorporated regions of Iowa. It updates existing zoning authority to prioritize construction access while maintaining safety-based regulations.
