Landlords must complete a long-term radon test at least once every five years in residential buildings, performed by a licensed radon professional under Minnesota Radon Licensing Act section 144.4961.

Landlords must report the most recent radon test results to all current tenants, the commissioner of health, and the inspector; results must be made publicly available in a searchable electronic database.

Landlords must provide prospective tenants with the Department of Health's "Radon in Rental Properties" publication and a radon disclosure before executing a lease, identifying test dates, radon concentration records, and any mitigation measures taken.

Landlords must perform radon mitigation within 90 days of a test result indicating elevated radon concentration, using a licensed radon mitigation professional.

Tenants may sue landlords for violations in district court and receive $250 per violation plus reasonable attorney fees; falsifying test results entitles tenants to additional punitive damages of $500; the attorney general may also seek penalties under section 8.31.

Effective date is December 1, 2024, applying to leases entered into on or after that date.
