Jackson County Radon
Jackson County is mapped in EPA Zone 1, yet reviewed records identified no local requirement for radon-resistant construction. The state dashboard’s limited 2022–2023 snapshot reads below the federal action level—proof that a zone predicts risk, not the result in any one home.
EPA zone: Zone 1Region: Middle TennesseeState test data: State test figures seen once; shown with a caveat
Yes, it can be. Jackson County is in EPA Zone 1, the highest radon-potential category, where 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.
No. Gainesboro has no adopted residential code, and no county building code was found for unincorporated areas. Local code details
Order a free short-term kit from the Tennessee Radon Program online or by calling 1-800-232-1139. Place it on the lowest lived-in floor, about 3 feet off the floor, for 3 to 5 days, then mail it back right away. How to test your home
EPA recommends fixing your home if radon is 4 pCi/L or higher, and considering a fix between 2 and 4 pCi/L. Confirm a high short-term result with a second test first. What your result means
Tennessee doesn't license radon professionals, so look for NRPP or NRSB certification. Search both national directories by ZIP code; certified professionals often serve Jackson County from nearby cities. How to choose a radon professional
Jackson County is in EPA Zone 1, the highest-potential classification. In the Tennessee dashboard’s 2022–2023 records, however, the county tooltip showed an average of 2.3 pCi/L and a maximum of 3.8 pCi/L.

Reviewed records point the same way in both jurisdictions: Gainesboro’s current codification has no adopted IRC, while the county is outside the state’s residential-enforcement list and no county building code was found. Definitive legal status awaits direct records confirmation.
Tennessee doesn't license radon testers or mitigators, so national certification is the best way to check qualifications. The Tennessee Radon Program points residents to two directories: search them by ZIP code and widen the radius if nothing is listed nearby.
We don't recommend or rank companies. Before you hire, check the certification number in the directory yourself and ask for a follow-up test after any system is installed. Questions to ask a radon professional.
Tennessee’s standard disclosure form advises buyers to use a radon inspection contingency, but the state does not mandate a radon-specific seller disclosure.
Zone 1 is a reason to test, not a diagnosis. Home age does not remove the need for a measurement.
Use the inspection period to preserve time for a short-term test or traveling professional.
No radon appendix was identified in reviewed local records, and the statewide code does not adopt one.
Completed NRPP and NRSB RMS searches found no local provider. TDEC offers free homeowner test kits, and traveling providers may add lead time.
