Radon Contractor Licensing in Colorado
Colorado licensing
Colorado requires a state license to work as a radon mitigation professional. Since July 1, 2022, under House Bill 21-1195, it is unlawful to practice as a radon measurement or mitigation professional without a license from the Division of Professions and Occupations at the Department of Regulatory Agencies (DORA). Licenses can be verified through DORA's online license lookup.
