The Illinois Radon Awareness Act, which took effect January 1, 2008, requires sellers of a home to provide anyone buying their home, condominium or other residential property in Illinois with information about indoor radon exposure and the fact that radon is the leading cause of lung cancer in non-smokers and the second leading cause of lung cancer overall.  The new law doesn’t require that homes be tested for radon prior to the sale or that radon remediation work be conducted if test results show high levels of radon.  However, under the new law, if a radon test has been conducted on the home those results must be provided to the buyer.

The Illinois Emergency Management Agency (IEMA) strongly recommends ALL homebuyers have an indoor radon test performed prior to purchase or taking occupancy, and mitigation if elevated levels are found.

The buyer, seller and realtor must all sign a disclosure agreement stating that all parties understand the dangers of radon and their obligations under Illinois law.
