RADON: New Requirements and Standards
In January, during National Radon Action Month, new radon policies and standards were introduced that can significantly affect how you do business.
- New HUD Radon Requirements
- RRNC 2.0: Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses
- A Provisional Standard for Radon Mitigation in Multifamily Housing
New HUD Radon Requirements
On February 4, HUD, in conjunction with the U.S. Department of Energy, U.S. Environmental Protection Agency, U.S. Department of Health and Human Services, and the White House Council on Environmental Quality announced the 2013 Advancing Healthy Housing - A Strategy for Action. Included were documents dated January 31 describing new radon testing and mitigation requirements for Multifamily Insured mortgage applications.
The new HUD requirements include:
- A Radon Report that includes the results of testing and the details of any mitigation deemed necessary.
- All testing and mitigation must be performed under the supervision of a certified Radon Professional.

A New Construction Radon Standard
RRNC 2.0: Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses
This AARST/ANSI Standard is a consensus standard developed by a committee of radon professionals, builders, architects, consumer advocates and state & federal government to further radon risk reduction in the United States by providing a model building code to achieve indoor radon concentrations of less than 4 pCi/L [148 Bq/m3] in new homes. RRNC 2.0 is a "code ready" standard that provides a significant improvement over the IRC Appendix F "Radon Control Methods" and is intended to replace Appendix F in the body of the building code.
RRNC 2.0 calls for:
- 1. Treating all foundation types ("Rough In").
- Soil Gas Collection Plenum (s)
- Electrical Junction Box
- Testing for occupancy permit.
- Activating system "Rough In" if necessary.
A Provisional Standard for Radon Mitigation in Multifamily Housing
The AARST Consortium on National Radon Standards announced approval and release of a new Provisional American National Standard for radon mitigation professionals entitled, "Radon Mitigation Standards In Multifamily Buildings." The new document establishes preliminary standards for mitigating multifamily housing in the United States.
Prior to this document, no standards or guidance documents have existed for mitigating radon from apartments or multifamily dwellings. The intent of the standard is to reduce not only health risks associated with radon but to reduce liability for apartment managers, developers and the multifamily housing sector.
