Radon-Resistant New Construction

"Building In Radon Control" Click here for print quality (PDF) Installing a radon system during construction prepares the home for increased radon removal. If high radon levels are found after occupancy, a fan can be readily installed.

There are good reasons to install a radon system during construction:

  1. There is no reliable way to test the ground in advance for radon.

  2. The average residentail radon level in Pennsylvania is 7-8 pCi/L. This is significantly above the EPA's action level of 4 pCi/L.

  3. The cost of installing the radon system during construction should be less than installing one after the fact.

  4. Building the radon system internally should keep aesthetics of the home in tact. If radon is not addressed during construction, an outside radon system may be required if the radon test comes back greater than 4 pCi/L.
Building Code Requirements

The state-wide building code does not require radon-resistant new construction. Local officials, on the other hand, may have adopted this portion of the building code. Calling your local municipality will tell you what is required.

Caution

Although the work is straight forward, there are many pitfalls to avoid. A builder doing this work should carefully look over the available material and gain the necessary knowledge. Hiring a Pennsylvania certified mitigator during construction is not required but would certainly be beneficial. Any person performing radon work after the home’s occupancy requires Pennsylvania certification. DEP certifies radon mitigators in Pennsylvania.

Radon testing is recommended shortly after occupancy to determine if the system is to be activated with a fan.

Training

RRNC Training is available. This training is designed for code officials and builders and can be used for continuing education.
