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.
