Radon-Resistant New Construction (RRNC)

Builder Directory - Introduction

The Directory provides an opportunity for builders who are using RRNC techniques to reach home buyers who are looking for new homes that may reduce exposure to radon. The Directory is a one-stop service for home buyers looking to find builders using RRNC techniques.

Some builders incorporate RRNC techniques voluntarily while others do it to meet code requirements. EPA encourages all builders who use the recommended radon-resistant techniques to be listed in the new Radon Resistant New Construction Directory of Builders.

EPA is not endorsing or promoting any individual builder or home. The information on the Directory pages is provided as a public service.


We'd like to help your company qualify for the Directory of Builders Using Radon-Resistant New Construction Techniques. Let us work with your company to help you learn about and incorporate the basic RRNC techniques. EPA has many no-cost educational and technical resources that you can use. I'd like more information on RRNC.

If you have questions or comments, please write to us at rrnc@epa.gov
