Radon Control in New Home Construction:
Developments in State Policy
In 2012, Illinois enacted legislation requiring that all new residential construction in the state include passive radon resistant construction techniques, as defined by the legislation. See Illinois Public Act 097-0953 (H.B. 4665). The legislation directed the Illinois Emergency Management Agency to develop rules to implement the new law and established a Radon-Resistant Building Codes Task Force to make recommendations concerning the adoption of rules by July 1, 2013. Local governments are authorized to adopt and enforce state rules governing radon resistant new construction or to adopt local rules that are at least as stringent.
According to the legislation, the installation of radon resistant construction may be performed by a residential building contractor or a radon contractor during new residential construction, however, only a radon contractor is permitted to install a radon vent fan or upgrade a passive new construction pipe to an active mitigation system.
