The Chicago City Council passed the Residential Landlord and Tenant Ordinance (RLTO) in 1986 to protect and promote the public health, safety and welfare of Chicago’s renters. It established the rights and obligations of the landlord and the tenant in the rental of Chicago apartments. The RLTO details what the landlord must provide and maintain in the apartment and what remedies are available to the tenant if the landlord does not do so. It also details the responsibilities of the tenant and the remedies available to the landlord if the tenant does not fulfill them. Other subjects of the RLTO include security deposits, subleases, the landlord’s right of access and illegal lease clauses.
