New Illinois law expands tenants rights if radon found in home – WGEM (Quincy)

Tenants have 90 days to test for radon. If it comes back positive, the landlord must cover at least half the mitigation costs. The tenant can also end the lease if radon levels exceed IEMA’s safety standard. Tenants can test after 90 days but the law would not automatically allow them to void their lease if the test comes back positive.
