Here is something most buyers do not realize until they are at the table: every Iowa home sale includes radon paperwork. Under the Iowa Real Estate Commission’s disclosure rules (Iowa Admin. Code 193E ch. 14, implementing Iowa Code chapters 558A and 543B), the seller’s property condition disclosure asks whether the home has ever been tested for radon, with the date and results — and the buyer must be provided the official Iowa Radon Home-Buyers and Sellers Fact Sheet from Iowa HHS, acknowledged in writing on the disclosure.
Iowa does not require testing or mitigation at sale. But it does require the conversation. Smart buyers and sellers get ahead of it. Full breakdown of the disclosure rules here.

Make a radon test part of your inspection contingency — in a state where 71.6% of homes test at or above the action level (the largest percentage of any state, per the Iowa Radon Survey), the odds your house is affected are real. Use a certified measurement professional: transaction tests follow strict protocols (48-hour minimum, closed-house conditions, tamper-resistant placement) so the result stands up when you negotiate. If the result is 4.0 pCi/L or higher, a mitigation system is a normal, priceable repair — typically $800–$2,500 — not a reason to walk away from a house you love.
Two honest paths: test before listing, and if it is high, mitigate and market the house with a working system and a verified low number — in Iowa, “already mitigated” is a selling point. Or disclose what you know and let the buyer test — legal, but it hands the timing and the negotiating frame to the buyer’s schedule. What you cannot do is leave known results off the disclosure: the form asks directly, and it is signed.
A transaction radon test needs a 48-hour minimum run plus scheduling on both ends. If your inspection window is 10 days, book the radon test the day the offer is accepted, not day 7. We can connect you with a certified professional who handles real estate testing in Black Hawk County on transaction timelines.
When a transaction test comes back high, the usual outcomes are: seller installs the system before closing (with a post-installation retest), a price credit for the buyer to install it after, or a split. All three work. The system should be installed by a state-certified mitigation professional and end with a verified retest — the same standard as any other job.
