Federal law requires landlords, including all Chicago apartment rental landlords, who lease apartments or other property constructed before 1978 to disclose the presence of any known lead-based paint hazards and provide prospective tenants with copies of any records or reports pertaining to any such lead-based paint hazards. Federal law further requires all landlords to provide prospective tenants with an EPA-approved lead-based paint pamphlet regarding lead-based paint hazards. A sample lead-based paint disclosure form and a copy of the EPA-approved pamphlet are available here. Chicago apartment landlords should ensure that the prospective tenant initials the form to acknowledge that the requisite disclosures were made. In cases when residential property built before 1978 is sold rather than leased, the seller is also required to provide the buyer with a ten-day opportunity to conduct a lead-based paint risk assessment. However, in writing, the parties may agree to lengthen, shorten, or eliminate the period for inspection.
