Licensing for Radon Mitigation Company and Sole Proprietor
On December 28, 2018, a Ramsey County District Court judge issued an order in an on-going lawsuit filed against the Minnesota Department of Health (MDH). That order, in effect, prevents MDH from enforcing certain radon mitigation statutes and rules that were scheduled to become effective on January 1 of 2019. Under the order, MDH for the time being cannot regulate or enforce the statutes and rules that apply to radon mitigation professionals that conduct mitigation in residences. Until further order of the Court, MDH must comply with the order. Other parts of the radon statutes and rules are not affected by the Court’s order. The radon measurement aspects of the statute and rules remain unchanged. If you are conducting radon measurement in a building you do not own or lease, you need to have a radon professional license. For more information, see the statement ‘Radon Licensure Changes due to Temporary Injunction’.
Who needs a company license?
