Relating to radon testing and mitigation for the conveyance of single-family residences, and including applicability provisions

This bill relates to radon testing and mitigation for the conveyance of single-family residences. The bill defines “single-family residence” as existing and newly built residential dwellings designed for occupancy by one household and located on property zoned for single-family residential use. The definition includes detached dwellings and townhouses and excludes duplexes, multifamily dwellings, and condominiums. The bill prohibits a county recorder from recording a deed conveying a single-family residence unless the deed is accompanied by a sworn affidavit executed by the grantor and grantee affirming that the conveyance complies with the bill. The bill requires that, prior to conveyance of a single-family residence, the grantor conduct a radon test in accordance with the rules adopted by the department of health and human services. A grantor must install a radon mitigation system if the radon test indicates radon concentrations at or above the level at which mitigation is recommended by the United States environmental protection agency. If the radon mitigation system is present but not functioning at the time of sale, the grantor must repair or replace the existing radon mitigation system. The bill applies to conveyances occurring on or after the effective date of the bill.
