As part of the Chicago war on bed bugs, landlords whose apartments are governed by the Residential Landlord Tenant Ordinance (the CRLTO) must provide all prospective tenants with a brochure prepared by the Chicago Department of Health relating to the prevention and treatment of bed bugs. A copy of this form is available for download here. The CRLTO encompasses most Chicago apartments, although the most common exception extends to owner-occupied buildings of six units or less. (The types of landlords exempted from the CRLTO are identified in Chapter 5, Section 12-020, of the Chicago Municipal Code.)
