Colorado Licensure Frequently Asked Questions
On June 30, 2021, Governor Jared Polis signed Colorado House Bill 21-1195. Beginning on July 1, 2022, Radon Measurement and Mitigation Professionals in Colorado must acquire a license to perform radon work in the State, under the Radon Measurement and Mitigation Licensing Act.
Why was this law passed?
In 2021, the Colorado General Assembly found and declared that “the prevalence of Colorado homes with excessive levels of radon has created a market in which unqualified individuals are representing themselves and practicing as radon professionals. Radon is the second leading cause of lung cancer, causing approximately twenty thousand deaths a year in the United States, including five hundred deaths in Colorado. Therefore, to protect the public, it is necessary to establish minimum qualifications for radon professionals and to require professionals who possess such qualifications to acquire a license before performing radon measurement or radon mitigation.”
Who must be licensed?
Those performing radon measurement or radon mitigation in Colorado must be licensed, unless they meet an exemption. Only an individual who obtains a license may claim to be a radon measurement professional or radon mitigation professional or use the title “radon measurement professional” or “radon mitigation professional” or any other title suggesting that the individual is qualified to perform radon measurement or radon mitigation.
