Radon Mitigation in Powdersville, SC
Powdersville is a growing community just eight miles from Greenville, but it's on the Anderson County side of the line. That puts it outside Greenville's radon building rules, which makes testing even more worthwhile.

Powdersville is an unincorporated community, a census-designated place in Anderson County rather than a city with its own government. For radon, that means it shares Anderson County's EPA Zone 2 rating.
Zone 2 is not a safe zone. South Carolina radon program data puts the Anderson County average at 1.7 pCi/L across 711 initial tests, but the highest result was 38.0 pCi/L. Just across the Saluda River, Greenville County averages 3.4 pCi/L and is the state's only Zone 1 county. Soil doesn't follow county lines.
The EPA says to test every home, regardless of zone. Fix at 4 pCi/L or higher, and consider fixing between 2 and 4.
A community that doubled in two decades
Powdersville grew from 5,362 people in 2000 to 10,025 in 2020. Much of that growth is newer subdivision housing along the I-85 corridor and near the Saluda River, close enough to commute into Greenville.
Here's the catch: Greenville County is the only county in South Carolina that requires radon-control methods in new homes. A house built a mile away in Greenville County may have a passive radon pipe and sealed vapor barrier by code. A similar house in Powdersville likely doesn't, because Anderson County has no such requirement.
Newer homes are tight and energy-efficient, which is good, but that can also let radon build up. If your builder did install a radon-ready pipe, adding a fan to activate it is often a straightforward job. Look for a labeled PVC pipe in a closet, garage or attic.

Powdersville radon questions
Powdersville is close to Greenville. Does Greenville's Zone 1 rating apply?
No. Powdersville is an unincorporated community in Anderson County, which the EPA rates Zone 2. But Zone 2 isn't safe: Anderson County tests reached 38.0 pCi/L. Neighboring Greenville County averages 3.4 pCi/L. The EPA recommends testing every home either way.
Was my newer Powdersville home built with radon protection?
Probably not by requirement. Greenville County is the only South Carolina county that requires radon-control methods in new homes, and Powdersville is in Anderson County. Some builders add a passive pipe anyway. Look for a labeled pipe in a closet, garage or attic, and test to know your level.
Who do I call about permits in Powdersville?
Because Powdersville is unincorporated, county offices handle building questions rather than a town hall. We'll go over what applies to your address during the free estimate and walk you through where the pipe and fan will go before any work starts.
