Before you plan radon mitigation in Hiawatha, check what the city's code does and doesn't require for new houses.
Local radon notes for Hiawatha
Hiawatha's code, in section 155.25, amends the city building code by repealing Section BE 104 Testing of the residential code's Appendix BE, Radon Control Methods [1]. Linn County's results chart says a reading of 8 pCi/L or more calls for a short-term follow-up within the next few weeks [2].
Does Hiawatha require radon testing in new houses?
No. Section 155.25 repeals the appendix's testing section, BE 104, so the city code doesn't add a testing step for new houses. A test is up to the owner [1].
When should Hiawatha homeowners test?
Linn County Public Health suggests testing if you've never tested, when you buy or sell, before and after a renovation, and before you turn a basement into a bedroom [2].
Iowa's statewide rules for testers and mitigation specialists are on how it works. To read up first, try radon testing, new construction radon or fan replacement. City pages: Cedar Rapids and Iowa City. Every other town is listed on all service areas.

We're a referral service, not a contractor. We send mitigation requests only to contractors on Iowa HHS's current credentialed list and testing requests only to state-certified radon measurement specialists, but we don't otherwise vet them, a referral is not an endorsement, and independent contractors may pay us for referrals.
