EPA radon potential
Low predicted potential, below 2 pCi/L on average. Elevated homes can still occur.
The bottom line
Zone 3 does not clear a house.
EPA’s zone map estimates countywide potential; it does not measure an address. Haywood’s state-dashboard tooltip had blank average, median and maximum fields on three checks, leaving buyers without usable local results.
County dashboard fields
Average, median and maximum showed no values on three observations.
Certified pros based in-county
No NRPP- or NRSB-listed professional was found in Haywood County.
Risk profile
A low-zone designation with too little local data.
The EPA map estimates potential. The Tennessee dashboard summarizes submitted test events. Neither predicts a specific house.
Haywood County is listed as EPA Radon Zone 3.
Zone 3 means predicted average indoor levels below 2 pCi/L. EPA’s zone guidance cautions that elevated homes have been found in every zone and that all homes should be tested.
The dashboard could not support a Haywood County statistic.
On three observations checked October 16, 2026, the tooltip identified “County: Haywood,” but its average, median and maximum fields were blank.
Read this as a data gap: blank fields do not mean zero radon, zero risk or a county full of tested homes. They mean no Haywood-specific aggregate could be verified from this 2022–2023 dashboard.
The lower charts are health-region aggregates.
Selecting Haywood did not make the pre- and post-mitigation charts county-level. Their columns remained grouped by health region, so they cannot support a Haywood test count, mitigation count or percentage above 4 pCi/L.
Building codes
One enforcement gap and one unpublished codebook.
Unincorporated Haywood County is absent from the state’s permit-required list. Brownsville runs its own local inspection program.
No state residential enforcement
- Haywood is absent from the state list of unincorporated counties requiring a state residential permit.
- No current county opt-out resolution was found online.
- The only permit located was a $5 assessor permit under a 1974 private act—not a code-enforcement program.
2018 IRC; Appendix Q only
- Tennessee’s baseline remains the amended 2018 IRC.
- The state rule adopts Appendix Q only.
- Appendix F, the 2018 radon appendix, is not adopted under the state program.
Local enforcement; appendix unknown
- The city has a Codes Office, building permits and required inspections.
- Its IRC edition, adopting ordinance and appendix list were not available online.
- Radon-resistant construction status inside the city remains unverified.
No verified radon mandate
- No county- or Brownsville-specific radon rule was found.
- No local rule for schools, government buildings or real estate transactions was found.
- Brownsville requires direct confirmation before calling its status optional.
Appendix lists—not the code edition alone—decide the mandate.
The state rule is explicit about Appendix Q. Brownsville’s own appendix list is the missing record.

For homebuyers
Test the house—not the ZIP code.
Tennessee disclosure asks what a seller knows about radon; it does not require the seller to test.
Add radon to the inspection contingency.
The disclosure form names radon but permits “Unknown.” A pre-purchase test gives the buyer evidence the form may not.
Test new homes near Brownsville and Stanton, too.
No countywide radon-resistant mandate was verified. New construction is not automatically tested or protected simply because it is new.
Ask who issued the permit.
Inside Brownsville, request the city’s adopted IRC and appendix list. Outside the city, do not assume state residential inspection applied.
Use Tennessee’s free-kit program.

BlueOval City raises the stakes for new-home due diligence.
Ford’s development near Stanton is expected to pressure housing demand across Haywood and Madison counties, although production has been delayed toward 2029 and the promised growth remains a forecast. If more homes arrive without verified radon-resistant requirements, testing becomes the practical buyer safeguard.
How do I find a certified radon professional in Haywood County?
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.
Answers in brief
Haywood County radon FAQ
Is Haywood County in a high-radon area?
Haywood County is listed as Zone 3, indicating predicted average indoor radon below 2 pCi/L. Elevated homes still occur in every zone, so only a test can determine a home’s level.
What did the Tennessee dashboard show?
On three observations on October 16, 2026, the tooltip identified Haywood County but displayed no numeric average, median or maximum for 2022–2023. No county statistic could be verified.
Is radon-resistant construction required?
No countywide mandate could be verified. Unincorporated Haywood County is outside state residential enforcement. Brownsville runs its own codes program, but its current IRC edition and appendix list remain unpublished.
Should a new home be tested?
Yes. No verified countywide rule guarantees radon-resistant features, and a test measures the home itself.
Are local certified testers available?
No NRPP- or NRSB-listed measurement professional was based in Haywood or Madison County on October 16, 2026. The nearest NRPP listings were in Memphis, roughly 44 to 49 miles from Brownsville.
Can I get a free test kit?
TDEC’s statewide indoor Radon Program offers free radon test kits to Tennessee homeowners.
