Iowa radon resources

Who answers what in Iowa

Iowa state health department radon programme

Certification of radon measurement and mitigation specialists, credential verification, testing guidance, and state radon information.

Your county or city building department

Whether a permit is required for the slab penetration and the dedicated electrical circuit. Local question, not a state one.

Licensing and credentials

Iowa certifies radon measurement and mitigation specialists through the state health department. The credential is Iowa-specific and is what should be verified before hiring — a general contractor licence is not a radon credential, and measurement and mitigation are certified separately.

What to verify before you hire

• Ask for the Iowa certification number as written on the contract.
• Confirm it is current and covers mitigation, not measurement only.
• Ask which credential the party performing the verification test holds.
• Confirm the post-mitigation verification test is inside the quoted price.

Disclosure and transactions

Iowa sellers disclose known radon information on the state residential disclosure form. Nothing in Iowa law requires a seller to test or to mitigate. Because many properties changing hands have never been measured, buyers should assume no data exists and order their own test during the inspection period rather than relying on seller knowledge.

Testing resources

Start with a short-term test on the lowest lived-in level under closed-building conditions, and prefer the heating season if you have a choice — Iowa houses close up for months, and winter stack effect draws harder on the soil. The state health department publishes testing guidance and maintains certified professional listings.

What this page deliberately does not state

We do not restate Iowa certification fees, renewal cycles, or application requirements, because those change and cannot be re-verified from this environment. The state health department radon programme is the authoritative source.
