Richmond City
Richmond City is classified as EPA Radon Zone 3, the lowest risk category. The predicted average indoor radon screening level is below 2 pCi/L. However, elevated radon has been found in homes in all three zones, and the EPA recommends that all homes be tested.
Richmond City is classified as EPA Radon Zone 3, the lowest risk category, with predicted average indoor levels below 2 pCi/L. It is one of 44 Zone 3 counties in Virginia (32% of the state's 136 counties). While the overall risk is lower, the EPA still recommends testing all homes — elevated radon has been found in homes in every zone across the country. Local geology can vary significantly even within a single county.
What This Means for Richmond City
Should You Test?
The EPA recommends testing all homes, even in Zone 3. While predicted levels are the lowest, elevated radon has been found in homes in every zone. Geology can vary significantly within a county, and individual home construction plays a major role. A simple test kit costs $15–$30.
Real Estate
While this area has the lowest predicted radon levels, it's still good practice to include radon testing in a home inspection, especially for homes with basements or slab-on-grade foundations. A basic test costs $15–$30 and provides peace of mind.
New Construction
While radon-resistant construction is not as critical in Zone 3, the incremental cost ($350–$500) during new construction is modest insurance. At minimum, consider installing a passive radon vent pipe during construction — it can easily be activated with a fan later if testing reveals elevated levels.
