A bill for an act concerning radon testing in rental properties.

HF 700 requires landlords in Iowa rental properties to address elevated radon levels detected by tenants. Tenants may test for radon or hire a certified professional; if results show 4 picocuries per liter or higher (the EPA action level), they must notify the landlord in writing. Landlords must then arrange a confirmatory test, and if radon remains at or above that level, install a certified radon mitigation system within 90 days, followed by retesting. If landlords fail to install mitigation or radon levels persist, tenants may terminate their lease with full rent and deposit refunds, no penalties, and written notice. This bill directly affects renters and landlords in Iowa housing by establishing clear radon testing, mitigation, and lease termination procedures.
