3 credentialed Iowa radon professionals serving Iowa City, sourced from the Iowa HHS credential rosters and cross-checked against each company's own site. Filter by what you actually need — a mitigation install, a test, or both.
Iowa City Municipal Code §17-5-18 requires radon testing for single-family and duplex rental units (owner-occupied homes are not covered). Testing must be done by a state-certified radon measurement specialist, and results are reported to the City. If a test comes back at or above 4.0 pCi/L, the code requires mitigation within 90 days. Units must be retested every 8 years — every 4 years if a bedroom is in the basement.
Sourced from the municipal code text and a city bulletin describing it; the two sources we found disagree on the exact date the requirement took effect, so we're not stating one here. Landlords should confirm current requirements and any compliance deadline directly with the City of Iowa City rather than relying on this note.
