State Requirements for Radon Resistant New Construction

Kentucky Housing Corporation policy mandates a passive radon reduction venting system for all newly constructed single-family units. This passive system is designed to prevent radon exposure before mitigation is needed. The vent pipe must pass through a heated portion of the structure and an accessible attic space or chase.

Future Upgrades for Radon Resistant New Construction

The EPA allows a passive RRNC system to be converted into an active system later. If a radon test shows elevated levels, a fan can be installed. This fan operation can add about $30 to $300 per year to the home’s energy bill because it draws 100 to 300 watts continuously.

Installation Requirements in Lexington

To allow for future fan installation, Kentucky Housing Corporation policy requires electrical provisions to be roughed in at an accessible attic or chase. The direct answer for Lexington is that RRNC is appropriate because state policy requires passive radon rough-in for new single-family units.

What to do next

Verify that the contractor is NRPP-certified or NRSB-certified, as state law requires contractors to be licensed.
Confirm that the builder is incorporating electrical provisions in an accessible attic or chase for future fan installation.
Ask for a quote that details the passive system's cost, which is approximately $600 to $800.
Consult the Kentucky state radon office at radon.ky.gov for local resources.
