AN ACT RELATING TO BUSINESSES AND PROFESSIONS -- REAL ESTATE SALES DISCLOSURES

SB 2424 mandates radon testing and mitigation protocols for most residential real estate transactions starting on June 1, 2027. The bill requires a certified radon test to be conducted no earlier than one year before closing, with results shared between buyers, sellers, and lenders. If unsafe radon levels are detected, the law requires a licensed professional to install a mitigation system before the sale finalizes, or place the estimated cost in escrow if immediate installation isn't possible. Certain sales, such as foreclosures, inherited properties, or homes being demolished, are exempt from these testing requirements. Additionally, the buyer is generally responsible for paying for the test unless the seller already has a recent negative test result on file.
