Greenville County public works committee votes to forward radon appendix adoption to full council

The Greenville County Roads, Infrastructure and Public Works Committee voted March 3 to forward consideration of the radon appendix in the 2024 South Carolina building codes to the full county council.

Darren Brock, who addressed the committee as a presenter on the item, said the county must take local action because radon provisions appear in an appendix rather than the body of the state code. "So the body of the code is adopted by the building codes council, but the radon is an appendix," Brock told the committee, adding that Greenville County is the only county in the code that currently requires radon provisions locally.

Brock summarized the committee's approach as limited: "We don't we're not gonna do it adopt the testing portion of it, only the parts that requires the passive installation," he said, explaining the county's intention to require passive radon-mitigation systems in new construction while not imposing a builder testing requirement.

After the presentation, the committee chair called for a motion to forward the radon appendix adoption to the full council. Members voiced their approval and the chair declared the motion passed, advancing the item for further consideration at the council level.

The committee also approved minutes from its Jan. 6, 2026 meeting earlier in the session and then adjourned. The action to forward the radon appendix does not itself adopt a local requirement; it moves the item to the full Greenville County Council for consideration and any formal adoption would require subsequent council action.
