The rule

Does Michigan license radon professionals?

No. Michigan's radon program page, checked on October 3, 2026, says:

Michigan does not license or regulate radon testing and mitigation contractors.
Michigan Indoor Radon Program, read October 3, 2026

Michigan is not on the list of states with radon credentialing programs that EPA's state contacts page publishes. Licensing is done by the state, not by the national programs, and EPA requires states that receive radon grants to give the public a list of only those providers credentialed by the state or by NRPP or NRSB.

Before you hire

How to check a credential in Michigan

  1. Michigan's rule

    Michigan's radon program says the state does not license radon professionals, so ask for a national certification instead, and check it in the next two steps.

  2. NRPP's search

    The National Radon Proficiency Program's search finds its Certified Mitigation Specialists and Certified Measurement Professionals by area, by name, or by the 6-digit NRPP ID number a professional can give you.

  3. NRSB's search

    The National Radon Safety Board's search finds a professional in your area, or confirms that a named professional is NRSB certified.

  4. The ID card

    The programs usually issue a photo ID card showing the holder's qualifications and its expiry date. Ask to see it, and if in doubt, check with the body that issued it.
