Cook County & Chicago RLTO Protections
In Chicago, tenants are shielded by the Chicago Residential Landlord and Tenant Ordinance (RLTO), which imposes strict statutory duties on landlords and allows tenants to withhold rent or deduct repairs for housing code non-compliance. In Cook County, cases must first proceed through the mandatory Early Resolution Program (ERP) before trial.
