New Radon Standards Lower Risk in New and Existing Multi-Family Housing

New Radon Standards lower risk in new and existing Multi-family Housing

There are three new requirements and standards for radon testing and mitigation in regards to multi-family housing and apartment buildings.

Radon Requirements for Multifamily Housing Mortgages

The first concerns mortgage applications. HUD is now requiring a radon report for all multifamily insured mortgage applications. The report must include the results of testing and any mitigation needed. They are also requiring that all testing is done by a certified radon professional. This effort; the 2013 Advancing Healthy Housing–A Strategy for Action, is in effect as of January 31, 2013.

New “Code Ready” Standard for lowering radon risk in new construction

There is also a new standard for new construction to lower the risk of radon in multifamily dwellings and townhouses. 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)
    • Piping
    • Electrical Junction Box
  2. Testing for occupancy permit.
  3. Activating system “rough in” if necessary.

New National Radon Standard for mitigating multifamily housing

The American Association of Radon Scientists and Technologists (AARST) Consortium on National Radon Standards also released a new Provisional American National Standard for radon mitigation professionals, “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.
