In 2015, the Minnesota Legislature, at the request of the Minnesota Department of Health MDH created a new license for Radon Mitigators and Radon Testers Effective January 2018 . Most Radon Mitigators and Testers are certified through NRPP National Certification, which is recognized by MDH . The Minnesota Radon Licensing Act, was passed without input from the industry stakeholders. In 2016 the industry worked with the legislature to make changes to the radon licensing act. While progress was made, the law and subsequent rules will cause significant costs to contractors and consumers, without any additional benefit. Below the industry outlines the needs to repeal the law and start over.


1 . Onerous Fees and Continuing Educations Requirements:

The Minnesota Radon industry is relatively small specialty industry. According to the Minnesota Department of Health (MDH) there are roughly 4,200 Radon mitigations performed per year in Minnesota. The average cost of a mitigation is $ 1500. That means the Mitigation industry is $ 6 . 3 Million. According to MDH, they will collect close to 500,000 in license fees and system tag revenue, which is nearly 5% of the revenue of the entire mitigation industry.


  • $ 100 Annually per Radon Mitigation Company1
  • $ 250 Annually per Radon Mitigation Professional 1
  • $ 150 Per Radon Measurement Professional (anyone who touches the radon test)1
  • $ 75 System Tag for every Mitigation job (close to 10% the cost of the average job)2

2 . Local Governments Already Require Licensing and Inspections:

Many cities are requiring a permit for Radon mitigation with some requiring a city license. This includes Minnesota’s largest cities. The average permit and inspection fee is $ 90. 00 . The Minnesota Radon License created by the act would simply create double fees that would be passed along to consumers. Installation of a radon mitigation is outlined in the construction code and mechanical code. The Minnesota Department of Health should not regulate construction activities covered under MN building code. 3

3 . Testing For Radon Is Easy:

The MN Radon Licensing Act creates a special license for radon testing.  A vast majority of radon tests are done by certified home inspectors. The law as written requires anyone who places or retrieves a test, for compensation, to have a license. But, according to the Minnesota Department of Health website: “Radon testing is easy. You can test your home yourself or hire a qualified radon test company. Either approach takes only a small amount of time and effort .”

  • 1This fee is significantly higher than other MDH license fees. For example and Asbestos Contractor License in only $50.
  • 2The system tag is essentially a fee without a service. MDH has said at most they will do spot inspections.
  • 3Sub-Soil Exhaust – Section 512 – Sub-Slab Ventilation System (same as radon mitigation) – 2015 MN Mechanical Code 326b.1026 General Powers Commissioners

Sub d 6. – Radon Code (outlines radon system installation)

ASTM Standards E2121 – 13 Standard practice for installing Radon mitigation systems in existing low-rise residential buildings.
