Licensing for Radon Professionals
The Minnesota Radon Licensing Act (Minnesota Statutes 144.4961) was passed by the legislature and signed into law in May 2015. This act gives Minnesota Department of Health (MDH) the authority to write rules and enforce laws related to the radon industry in the state.
The lawsuit against the Commissioner of Health, concerning the Minnesota Radon Licensing Act (MRLA), was dismissed by a district court judge on February 20, 2020. MDH is moving forward with implementing the residential mitigation licensure requirements under the MRLA and its associated rule. In the near future, MDH will provide additional information including deadlines for obtaining licenses and tags, and instructions for how to proceed if you hold a measurement or commercial mitigation license.
Who needs a license?
Professionals that measure and companies that perform radon lab analysis, must be licensed by MDH. Mitigation professionals and companies that mitigate non-residential buildings must be licensed.
- Measurement professionals: an individual who places or retrieves test device in buildings they do not own or lease.
- Mitigation professionals: an individual who installs or designs a radon mitigation system in a non-residential building they do not own or lease, or provides on-site supervision of mitigation work.
- Mitigation companies: a business or government entity that employs one or more licensed mitigation professional and performs or authorizes employees to perform radon mitigation in a non-residential building.
- Radon Analysis Laboratories: a business or government entity that analyzes passive radon test devices for the presence or concentration of radon. Contact MDH for information on licensing as a laboratory at 651-201-4601.
