Radon Disclosure Requirements When Selling a Home in New Hampshire
Radon Disclosure in New Hampshire Real Estate Transactions
New Hampshire requires sellers to disclose known radon testing results and any history of radon mitigation when selling a home. This disclosure is typically part of the seller's property disclosure statement.
If you have previously tested your home for radon, you are required to share those results with potential buyers. If a mitigation system is installed, you should disclose the installation date, the name of the installer, and any follow-up test results.
What Buyers Should Know
If you are buying a home in New Hampshire, request a radon test during the inspection period. New Hampshire is in EPA Zone 1, which means the area has high radon potential. A professional radon test costs $125 to $350 and takes 2 to 7 days.
If the test shows levels above 4 pCi/L, you have several options:
- Ask the seller to install a mitigation system before closing
- Negotiate a price reduction or closing credit to cover mitigation costs
- Accept the results and install mitigation yourself after closing
Radon mitigation in New Hampshire costs $800 to $2500. A properly installed system reduces radon by 80% to 99%, so elevated radon should not be a reason to walk away from an otherwise good home.
What Sellers Should Know
Proactive radon testing and mitigation can make your home more attractive to buyers. If you know your home has elevated radon and you install mitigation before listing, you can present the post-mitigation test results showing safe levels. This removes radon as a negotiation point and speeds up the closing process.
The cost of mitigation ($800 to $2500) is typically less than the price reduction a buyer would negotiate if they discover elevated radon during inspection.
