Home Buying & Selling

Buyers and sellers often test for radon during real estate transactions and the level of 4 pCi/L is commonly used to determine if mitigation is necessary. Though testing is a good idea for long-term health protection, there are no laws in Missouri that require this testing or that require mitigation by the seller. For more information consult the brochure "Home Buyer's and Seller's Guide to Radon."
