Authorizing cities to require radon testing for single family residences used as rental property

This bill gives authority to cities to adopt or enforce ordinances that require radon testing for a single family residence when the owner applies for or renews a rental permit with the city. A “single family residence” means a structure maintained and used as a single dwelling unit, notwithstanding that a dwelling unit generally shares one or more walls with another dwelling unit and the structure has direct access to a street or thoroughfare and shares neither heating facilities, hot water equipment, nor any other essential facility or service with another dwelling unit. If a city adopts or enforces a radon testing ordinance for a single family residence used as a rental property, the owner of the rental property must provide to the city copies of the test results performed by a person certified in accordance with Code chapter 136B. The bill provides the time frame for an owner to have a radon mitigation system installed in accordance with Code chapter 136B if radon test results reach a specified level, retesting requirements, and applicability of prior radon test results when applying for or renewing rental permits with a city.
