A bill for an act relating to radon testing and mitigation for the conveyance of single-family residences, and including applicability provisions.

This Iowa bill requires home sellers to test for radon before selling single-family homes (detached houses or townhouses on single-family zoned property, excluding condos and duplexes) and install mitigation if levels exceed EPA recommendations. Sellers must conduct tests per health department rules, install systems if needed, and verify reduced radon levels before closing. Both buyer and seller must sign a sworn affidavit confirming compliance, which county recorders must require before recording the deed. The law applies to sales occurring after its effective date.
