North Carolina Encourages Radon Resistant New Construction

by Margaret Henderson

The North Carolina Department of Health and Human Services Radon Program provides information to builders and developers in support of radon resistant new construction (RRNC). Test results for much of the state indicate radon levels exceeding the recommended EPA action level of 4 pCi/L. Therefore the potential exists for newly constructed homes to have excessive radon. Outreach to developers and builders is aimed at reducing the number of new homes that have high radon concentrations.

Ways in which this support to developers is provided include:

  • Facilitating training for developers;
  • Listing the certified testers and mitigators in North Carolina; and
  • Encouraging use of radon resistant new construction by providing additional information about advantages of using RRNC, how radon enters homes and details on the five elements of a passive system for radon removal.

Radon Program provide specifics to encourage developers about RRNC, including:

  • RRNC typically costs a builder between $250 and $750.
  • RRNC could cost less than $250 if the builder already uses some of the same techniques for moisture control.
  • For a builder, it is much less expensive to install a radon-resistant system during construction than to go back and fix a radon problem identified later.
  • If a new homeowner tests for radon and has to mitigate high levels, it could cost the builder or the owner more than an initial installation.
