Are passive radon systems required for additions?

According to the Minnesota Department of Labor and Industry every addition requires the installation of a passive radon system. Unlike new homes, existing homes can be easily tested for radon. BAM suggests you have your homeowner test their home. If the radon level is below 4.0 pico/L (the EPA “action level”), have the homeowner ask the local building official for waiver from this requirement in their addition.
