Builder and Contractor Resources for Radon-Resistant New Construction (RRNC)
On This Page:
Including radon-reducing features in new homes is cost-effective, and in demand by health conscious homebuyers. Some builders are installing complete fan-powered systems, especially in high radon potential areas. EPA recommends the American Society for Testing and Materials (ASTM) E1465-08 standard for radon-reducing features in new homes.

Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses (CCAH 2020)
To control for radon in the construction of new residential homes.
This standard provides minimum requirements for the rough-In of radon control system components in new dwelling units under construction. CCAH also includes minimum requirements for verifying if radon concentrations are below the national action level and, if required, activation of radon control systems. This standard is harmonized to compliment the standard designated as ANSI/AARST RRNC, which replicates construction activities for rough-In components only
Rough-In Of Radon Control Components In New Construction Of 1 & 2 Family Dwellings And Townhouses (RRNC 2020)
This standard provides minimum requirements for the rough-In of radon control system components in new dwelling units under construction. This standard is harmonized with ANSI/AARST CCAH, which additionally addresses requirements for verifying if radon concentrations are below the national action level and, if required, activation of radon control systems.

Contractor Report: The annual Builder Practices Report
Produced for EPA by the National Association of Home Builders Research Center Inc., this report for calendar 2010 is available as a PDF from the National Service Center for Environmental Publications (NSCEP). Reference EPA document number 402-K-12-001. The report includes information on radon-resistant home building practices for single-family homes, multifamily buildings, trends, costs and demographics.
EPA is making the report available in the belief that individuals, builders, state/local governments, researchers and radon professionals will find it useful. Voluntary adoption of radon-resistant new construction techniques by builders and building code authorities is an EPA radon program priority.
