What Chicago Landlords Are Legally Required to Maintain
Chicago has some of the most tenant-protective rental laws in the country. The Residential Landlord and Tenant Ordinance (RLTO) — Chicago Municipal Code Chapter 5-12 — establishes clear maintenance obligations for landlords and significant remedies for tenants when those obligations aren't met.
This guide is not legal advice. It is a practical summary of the maintenance obligations most relevant to Chicago property owners and managers. For legal questions, consult a Chicago real estate attorney.
The Core Standard: Habitability
Chicago landlords are required to maintain rental units in a "habitable" condition — meaning the unit must be fit for human occupancy and free from conditions that pose a threat to health or safety. The RLTO defines this through specific requirements.
What You're Required to Maintain
Heat
Requirement: Landlords must provide adequate heat from September 15 through June 1. The minimum temperature is 68°F during the day (6:30 AM–10:30 PM) and 66°F at night. Repair timeline: Heating failures must be addressed within 24 hours during heating season. Tenant remedy if not fixed: Tenants may withhold rent, repair and deduct (up to one month's rent), or terminate the lease if heat is not restored within the required timeframe.Plumbing
Requirement: All plumbing fixtures must be maintained in good working order. This includes hot and cold running water, functioning toilets, and drains that drain properly. Common violations: Dripping faucets (if they affect water pressure or waste), slow drains, running toilets, and non-functional hot water heaters. Repair timeline: Emergency plumbing failures (no water, sewage backup) must be addressed within 24 hours. Non-emergency plumbing repairs must be completed within a reasonable time (typically 7–14 days).Electrical
Requirement: All electrical systems must be maintained in safe working order. This includes functioning outlets, switches, and light fixtures in common areas. Common violations: Non-functional outlets, exposed wiring, tripping breakers, and non-functional smoke detectors. Repair timeline: Electrical hazards must be addressed immediately. Non-hazardous electrical repairs within 7–14 days.Structural Integrity
Requirement: Floors, walls, ceilings, roofs, and foundations must be maintained in good repair. Windows and doors must close and lock properly. Common violations: Water intrusion through roof or windows, damaged flooring, doors that don't close properly, and broken window locks.Pest Control
Requirement: Landlords are responsible for extermination of insects, rodents, and other pests when the infestation affects more than one unit or is caused by building conditions (not tenant behavior). Important distinction: If a tenant's behavior (food storage, cleanliness) causes an infestation limited to their unit, the landlord may be able to charge the tenant. If the infestation originates from the building structure or affects multiple units, it's the landlord's responsibility.Smoke and Carbon Monoxide Detectors
Requirement: Chicago requires working smoke detectors in every bedroom and on every floor. Carbon monoxide detectors are required in units with gas appliances, attached garages, or fireplaces. Landlord obligation: Install detectors before a new tenancy begins. Tenants are responsible for replacing batteries and notifying the landlord of malfunctions.Repair Timelines Under the RLTO
| Condition | Required Response Time |
|---|
| Emergency (no heat, no water, sewage backup, gas leak) | 24 hours |
| Urgent (non-functional appliances, significant water intrusion) | 72 hours |
| Non-urgent (cosmetic, minor repairs) | 14 days |
| Pest control | 7 days from notice |
Tenant Remedies for Non-Compliance
Chicago tenants have significant remedies when landlords fail to make required repairs:
Repair and deduct: Tenants may hire a contractor to make repairs and deduct the cost from rent (up to one month's rent) if the landlord fails to repair within the required timeframe after written notice. Rent withholding: Tenants may withhold a portion of rent proportional to the reduction in habitability if the landlord fails to repair after proper notice. Lease termination: For serious habitability violations, tenants may terminate the lease without penalty. Damages: Tenants may sue for actual damages, including relocation costs and the difference between the agreed rent and the fair rental value of the uninhabitable unit.Practical Compliance for Chicago Landlords
Document everything. Keep written records of all maintenance requests, your responses, and completed repairs. This is your primary defense against tenant claims. Respond in writing. Acknowledge maintenance requests in writing (email is sufficient) and provide a realistic repair timeline. This demonstrates good faith and starts the clock on the RLTO timeline. Use licensed contractors. Repairs made by unlicensed contractors may not satisfy RLTO requirements and can create additional liability. My Handyman Express is a licensed Class E contractor. Preventive maintenance. The most cost-effective way to stay RLTO-compliant is to prevent failures before they occur. Quarterly HVAC filter changes, annual plumbing inspections, and semi-annual building walkthroughs catch problems before they become tenant complaints.My Handyman Express provides maintenance plan services for Chicago landlords and property managers.
