Do NOT apply for a mitigation license if you only conduct mitigation in residential properties. Only mitigation professionals and companies that conduct mitigation work in non-residential buildings (schools and large buildings) are required to have a mitigation license (at this time, due to court order).

If you conduct radon measurement work, you are required to have a license. This includes mitigation professionals that only mitigate residences and also provide measurement services. If you already have a mitigation professional license, you do not need to apply for a measurement license (the mitigation professional license is a dual license for both measurement and mitigation).

To view your existing radon license applications, please log in and then select "View Applications" from the "Licenses" pull down bar above.
