A bill for an act relating to radon mitigation in residential buildings.

HF 82 requires new single-family or two-family residential construction in Iowa to include passive radon mitigation methods (like specific foundation designs) as part of the state building code. It directly affects new home builders and developers constructing these specific types of residences. The requirement applies only to projects starting after the rule is adopted by the building code commissioner. This is a concrete policy change to proactively address radon gas exposure in newly built homes.
