City of Aspen and Pitkin County offering free radon tests
City announces incentives for radon mitigation
Aspen, CO - January is National Radon Action Month. The city of Aspen, in partnership with Pitkin County, is taking proactive steps to address the potential threat of radon gas in local homes.
To encourage residents to safeguard their homes, the city and county are offering free radon test kits. Residents can pick up a free radon test kit during regular business hours at City Hall at the community development office on the first floor located at 427 Rio Grande Place or at the Pitkin County administrative building at 530 East Main St. in suite 205.
Radon is an invisible, odorless, naturally occurring radioactive gas that can enter homes through cracks in floors and foundations. It is the leading cause of lung cancer among non-smokers and is responsible for more than 20,000 lung cancer deaths in the United States each year. Due to Colorado’s geology, approximately 50% of homes in the state have elevated radon levels, making testing particularly important.
For homes that test high for radon, mitigation systems can significantly reduce exposure. To help offset mitigation costs, the city of Aspen environmental health and sustainability department is launching a new grant opportunity for qualifying Aspen–Pitkin County Housing Authority households with radon test results of 4 pCi/L or higher. Applications will open on March 1, 2026.
In addition to residential support, the city is expanding its radon efforts through a pilot project offering free radon testing for commercial buildings. This expanded testing will help city staff better understand radon levels across the community and assist in the development of future programs and incentives. Commercial building owners interested in participating can contact airquality@aspen.gov.
“We’re excited to continue to expand our radon efforts alongside Pitkin County and provide more resources for our community,” said Natalie Tsevdos, city of Aspen environmental health programs administrator. “We hope these programs help residents take action now while also strengthening our understanding of radon levels throughout Aspen.”
