Radon and Real Estate in Utah

Radon is the second leading cause of lung cancer. Before you buy or sell, know the facts — and know your home’s radon level.

For Buyers: Know Before You Close

Radon testing should be a standard part of every home inspection in Utah. There is no safe level of radon — the WHO recommends mitigation at 2.7 pCi/L, and a large proportion of Utah homes exceed this threshold. Testing takes 48–96 hours and provides concrete data for negotiating repairs or price adjustments.

If radon is found above the WHO threshold of 2.7 pCi/L, buyers can request mitigation as a condition of the sale or negotiate a credit to cover the $1,800–$2,300 installation cost.

For Sellers: Get Ahead of the Issue

Proactively testing and mitigating before listing removes uncertainty from your transaction. A home with a documented low radon level — or a professionally installed mitigation system — is a selling point, not a liability.

Utah law requires disclosure of known radon issues. Knowing your level before a buyer’s inspector finds it puts you in a much stronger negotiating position.
