Housing (Building Codes)

HF 2386 allows Iowa cities to require the first buyer of a single-family home in a new housing development to live in the home as their primary residence for one year after purchase. Cities may impose fines of up to 25% of the home’s fair market value for violations, but must include a good-faith sale exemption if the owner needs to sell during the occupancy period. The bill defines "new housing development" as homes sold for the first time, including newly built properties under city-developer agreements, and specifies "occupy" means physically living in the home as a residence. This bill directly affects first-time homebuyers in new developments and gives cities a regulatory tool to address potential investor speculation.

SF 595 updates Iowa's construction regulations by requiring state building code proposals to include cost impact reports on housing affordability. It prevents counties and cities from imposing additional fees or licensing requirements on licensed contractors (like plumbers and HVAC specialists) for work within their licensed scope. The bill also limits local governments from enforcing stricter stormwater management rules at construction sites than those initially approved in subdivision plans. These changes directly affect contractors, local governments, and homeowners through potential impacts on construction costs and regulatory processes.

This bill requires Iowa counties and cities to allow at least one accessory dwelling unit (ADU) per single-family residential lot. It prohibits local governments from imposing restrictions that are more stringent than those for primary homes, such as size limits below 1,000 sq. ft (except capping ADU size relative to the main house), extra parking requirements, or discriminatory occupancy rules. Counties and cities must approve ADU permit applications meeting state standards within 30 days, or the application is deemed approved. The bill directly affects local governments (through regulatory changes) and homeowners seeking to build or rent ADUs on their property.
