(Radio Iowa) – The Iowa House has sent the Senate a bill to require that home builders install passive radon mitigation systems in new homes. It also would establish a state tax credit for the installation of radon mitigation systems in existing homes and buildings. Representative Hans Wilz, of Ottumwa says E-P-A ratings show every county in the state has an elevated level of radon. “Seven out of 10 homes in Iowa have radon levels that pose a health risk,” Wilz says. “This isn’t limited to old homes or those with basements. Radon can be found in any home — new, old, anywhere where in our state.”

Radon is the leading cause of lung cancer in Iowans who are not smokers. Wilz says radon mitigation systems can save the state and its citizens hundreds of millions of dollars that would be spent on health care costs. “Every dollar spent on radon mitigation is going to save $20-$40 of avoided health care costs,” Wilz says. The bill would set up a state tax credit of up to a thousand dollars for installation of a radon mitigation system in existing structures. Individuals could claim the credit on their personal income taxes.

The credit would be available to some businesses as well as the managers of estates or trusts working to prepare a property for sale after the owner’s death. Starting in 2027, state law already requires regular radon testing of Iowa school buildings and mitigation if unsafe levels are found.
