An Act To Require Radon Testing For Certain Commercial And Residential Construction

LD 1232 requires radon testing and mitigation permits for new commercial construction, residential construction, and major commercial renovations needing a building permit. It mandates that registered professionals test for radon gas before construction begins, and if elevated levels are found, registered specialists must install mitigation systems. Homeowners acting as their own general contractor who provide over 50% of the framing and finishing labor are exempt, as are residential projects in municipalities without a building code. Violations incur penalties of $1,000 for commercial projects and $500 for residential projects, payable to Maine's Department of Health and Human Services.
