Chicago, IL Rental Inspections: Habitability Standards (2026)

Chicago habitability standards are established through the Residential Landlord and Tenant Ordinance (RLTO, Chapter 5-12) and the building code. Section 5-12-070 requires landlords to maintain rental units in compliance with all applicable building, housing, and health codes, creating an implied warranty of habitability. The Chicago Heat Ordinance sets specific temperature requirements: buildings with central heating must maintain at least 68 degrees Fahrenheit from 8:30 AM to 10:30 PM, and at least 66 degrees F from 10:30 PM to 8:30 AM during the heating season (September 15 through June 1). Units with individual heating equipment must be capable of maintaining 68 degrees F. Essential services that landlords must provide include heat, hot and cold running water, electricity to common areas, and functioning plumbing and sewage. Additional habitability requirements include: working smoke and carbon monoxide detectors, secure entry doors and windows, freedom from rodent and pest infestations, adequate ventilation, functioning appliances that were provided with the unit, and structural soundness. Common habitability violations include inadequate heat, water leaks, mold, pest infestations, and broken security features.
