IA SF2242

Sellers of single-family residences must conduct a radon test prior to conveyance, following rules adopted by the Iowa Department of Health and Human Services.

If radon levels meet or exceed EPA-recommended mitigation thresholds, sellers must install a radon mitigation system and perform a follow-up test to verify levels are acceptable before completing the sale.

Existing but non-functioning radon mitigation systems must be repaired or replaced by the seller prior to conveyance.

County recorders cannot record deeds for single-family residences unless accompanied by a sworn affidavit from both buyer and seller affirming compliance with radon testing and mitigation requirements.

Applies to detached dwellings and townhouses but excludes duplexes, multifamily dwellings, and condominiums.
