HUD radon requirements for radon-control design

HUD radon policy applies to multifamily properties seeking HUD-insured or HUD-assisted financing. Under the HUD MAP Guide framework, radon testing for these properties has to be performed by a qualified, certified radon professional, and properties with elevated results need a mitigation plan.

HUD references the ANSI/AARST standards as the technical basis for that work: CC-1000 for new construction and SGM-MFLB for existing buildings. So for a HUD deal, the radon-control design is not optional paperwork. It is part of getting the financing closed.

Our role is the engineered design itself. We produce the mitigation or new-construction design package built to the applicable AARST standard, reviewed and signed by a certified radon professional, so the credentialed sign-off HUD expects is already part of the deliverable. Radon testing of the property is performed separately by a certified tester.
