Multifamily HUD Radon Testing

What Is Considered A Multifamily Property?

Multifamily Radon Testing – According to the American Association of Radon Scientist and Technologists, a multifamily dwelling is 5 or more units. The dwellings are characterized as detached, semi-detached, row, walkup, or elevator-type rental or cooperative housing with complete kitchens and baths.

What Type Of Radon Test Are Used For Multifamily Properties?

Radon tests are classified as passive and continuous. Passive tests commonly include charcoal canisters, liquid scintillation devices, electret ion chambers, and alpha track (long-term) detectors.  Factor Testing uses an e-Perm test which delivers a more accurate test and provides faster results.

Can I Test My Multifamily Property Myself?

HUD requires all radon testing to be “performed under the supervision of a Radon Professional.”  Just as lead, asbestos, and other environmental inspections are assigned to third party professionals, mortgage lenders expect the radon testing to be performed by an
independent third party.

Do I Need A Radon Test If There Is Already A Radon System For The Building?

A building must be tested if a system is already installed to ensure it is working correctly and continues to reduce radon concentrations to acceptable levels. Post mitigation testing is required by the standards referenced in HUD’s Radon Policy and is required specifically in the
Policy, and must occur prior to Final Endorsement.

Can I Install My Own Radon Mitigation System In My Multifamily Building?

Multifamily Radon Testing – HUD requires all radon mitigation to be “performed under the supervision of a Radon Professional.” (See definition of Radon Professional in the HUD notice.) Mitigation of a large building can be extremely complex and should only be performed by a knowledgeable professional.
