RRNC Codes, Standards, and Resources


What are the codes or standards for radon-resistant new construction?

For details on national radon standards, or standards that relate to new homes in your area, visit the websites of the three organizations listed below.

    • ANSI-AARST Standard: Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses

ANSI/AARST has released "RRNC 2.0 Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses" to control for radon in the construction of new residential homes.  The standard, designated CCAH-2013, is written in code language.  Copies are available for $45 each for non-members, $30 each for AARST members from AARST-NRPP at http://www.aarst.org/bookstore.shtml


  • ASTM
    • Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings*

  • EPA
    • Radon Prevention in the Design and Construction of Schools and Other Large Buildings.
      It is typically easier and much less expensive to design and construct a new building with radon-resistant and/or easy-to-mitigate features, than to add these features after the building is completed and occupied.
