HUD's Office of Multifamily Housing requires radon testing for most FHA insured multifamily mortgages (MAP or TAP applications). HUD’s policy requires that the radon measurement be performed by a radon professional that is both certified (by NRPP or NRSB) and State licensed where applicable.  ARC-1 Radon is certified, licensed, insured and has seven years’ experience in the radon measurement business.
