Multifamily Testing


The U.S. Dept. of Housing & Urban Development (HUD), the Environmental Protection Agency (EPA), the National Institute of Standards (NIS) and other federal agencies, organized the "Advancing Healthy Housing" initiative that has identified radon testing and radon mitigation as major priorities in improving the healthfulness and safety of our nation’s housing.

If you are applying for HUD-backed financing or refinancing for a multi-family building, you must have a radon test performed by a radon professional and provide proof of radon mitigation if necessary.
