Local housing

Homes in Ames.

Ames housing runs to dense student rental stock alongside newer subdivisions, across the campus-adjacent neighborhoods and the outer subdivisions, on Des Moines Lobe till — and that mix shapes what a radon testing here needs to find.

Local conditions in Ames

Every county in Iowa, including Story County, is in EPA Radon Zone 1, the highest-potential zone, so testing matters whether you own a house near campus or in a newer Ames subdivision. Ames is a dense city, with high-density student rental housing in areas like Campustown alongside single-family homes, and basement use varies widely. We place the monitor in the lowest level that is regularly occupied under closed-house conditions, so the result reflects how the home is actually used, and explain next steps if the number is high.

Questions

Common questions.

Is radon really a concern in Iowa?
Yes. The Iowa Department of Natural Resources reports that more than two in five Iowa homes have radon levels that pose a significant health risk, and finished basements are where it concentrates.
How long does the test run?
A 48-hour minimum under closed-house conditions; the result is delivered with your inspection report.
Is Ames rental housing different to inspect?
Yes. Campus-adjacent housing carries heavy rental history — divided units, added bedrooms, altered egress and years of deferred maintenance. All of it is worth knowing plainly, including anything that looks unpermitted.
