About Illinois Radon Disclosure
The Illinois Radon Awareness Act (420 ILCS 46) requires landlords to disclose any known radon test results or hazards to prospective tenants before signing a lease. Illinois has elevated radon risk in many counties, particularly in the central and northern parts of the state. EPA recommends action when radon levels exceed 4.0 pCi/L; long-term exposure increases lung cancer risk.

Illinois tenants should review the radon disclosure carefully. If no testing has been done, consider purchasing an EPA-approved test kit (~$15-30) and testing the dwelling yourself.
