Radon in Spring Hill, Tennessee

Is radon a problem in Spring Hill, TN?

Yes, it can be. Spring Hill is in Maury County and Williamson County, which EPA places in Zone 1, the highest radon-potential category: the predicted average indoor screening level is above 4 pCi/L. Levels vary from house to house, so a test is the only way to know your home's level.

Do new homes in Spring Hill have to be built radon-resistant?

No. Spring Hill's 2024 code (Ordinance 26-07, effective June 1, 2026) references no appendices, including the radon appendix. The rule applies inside city limits, in both Maury and Williamson counties. Either way, ask your builder which radon features were installed and test after you move in: radon-resistant construction lowers the chance of high radon but doesn't replace a test.
