Yes. Iowa HHS certifies radon testers (measurement specialists, numbers starting RNTST) and credentials installers (mitigation specialists, numbers starting RNMIT). Mitigation rules in effect since July 1, 2026 require national ANSI/AARST installation standards and a level below 4 pCi/L after the system is installed.
No test is required. The seller disclosure statement does ask about radon: any known tests, the date of the last report and the results, and buyers must get the Iowa HHS radon fact sheet.
Not yet under state law. HF 2297, signed May 19, 2026, requires passive radon-resistant construction in new one- and two-family homes once the state building code commissioner adopts a rule. The draft rule's hearing was Oct. 21, 2026, and we found no adopted rule as of 2026-11-05. Locally, Johnson, Muscatine and Shelby counties and Harlan, Coralville, Iowa City and North Liberty have adopted a radon appendix (trade-group list).
