This bill authorizes cities in Iowa to implement ordinances that mandate radon testing for single-family residences used as rental properties when owners apply for new rental permits or renew expired ones. The new legal language specifies that these requirements apply to rental permits applied for or renewed on or after July 1, 2021. If a city enforces such an ordinance, property owners must submit radon test results to the city, and the bill outlines specific retesting intervals based on the results. For instance, if radon levels are below four picocuries per liter, retesting is required every eight years, while levels at or above that threshold necessitate the installation of a radon mitigation system and retesting within ninety days.

Additionally, the bill clarifies that existing radon mitigation systems must be retested every eight years, and prior radon tests conducted within two years of the rental permit application or expiration can satisfy the testing requirements. The definitions of "radon mitigation system" and "radon test" are also included, emphasizing that these must be performed by certified individuals as per the relevant code. Overall, the legislation aims to enhance safety in rental properties by ensuring regular monitoring and mitigation of radon levels.
