In Chicago and Cook County, landlords are not required to fix everything a tenant doesn’t like — but they are required to keep the unit safe, habitable, and in working order. Most confusion around repairs comes from not understanding where the line is between habitability and cosmetic or convenience issues.

The law doesn’t expect perfection. It expects basic living conditions.

At a high level, landlords are responsible for repairs that affect health, safety, and essential services. If something makes the unit unsafe, unsanitary, or unlivable, it’s generally the landlord’s responsibility to fix it — regardless of what the lease says.

Heat is one of the clearest examples. If the heating system isn’t working during the heating season, that’s not optional and not negotiable. The same is true for running water, hot water, electricity, and properly functioning plumbing. A tenant doesn’t have to live with no heat, no water, or raw sewage because a lease says “as-is.”

Structural integrity also matters. Issues like roof leaks, ceiling collapse risks, broken stairs, unstable railings, or unsafe floors fall squarely on the landlord. These aren’t cosmetic concerns — they’re safety issues.

Windows and doors are another common area of confusion. Landlords are generally responsible for making sure exterior doors and windows close properly, lock, and protect the unit from the elements. A broken lock or a window that won’t close isn’t just an inconvenience — it’s a security issue.

Appliances are slightly different. If an appliance is provided as part of the rental — such as a stove, refrigerator, or dishwasher — the landlord is typically responsible for keeping it in working order. If the tenant damages it through misuse, that’s another discussion. But normal wear and tear failures are not the tenant’s responsibility.

Electrical issues that pose a safety risk also fall on the landlord. Flickering lights due to faulty wiring, outlets that don’t work, exposed wiring, or repeated breaker failures aren’t things a tenant is expected to live with or repair themselves.

Pest issues are another area where landlords often get caught off guard. In Chicago and Cook County, infestations that affect habitability — such as rodents or insects — are usually the landlord’s responsibility to address, even if the tenant’s behavior may have contributed. This doesn’t mean tenants have no responsibility, but landlords can’t simply ignore an infestation once it’s reported.

Where landlords are not generally required to act is on purely cosmetic issues. Peeling paint (that is not lead-related), worn flooring, outdated cabinets, or minor cracks that don’t affect safety usually don’t trigger legal repair obligations. Tenants may not like them, but dislike alone doesn’t create a legal duty.

Another common misunderstanding involves tenant-caused damage. Landlords are not required to repair damage caused by a tenant’s misuse or neglect without addressing responsibility. You may still need to fix the issue to maintain habitability, but that doesn’t mean the tenant isn’t financially responsible for the damage.

Timing also matters. Chicago and Cook County expect landlords to respond to repair requests within a reasonable time, which depends on the seriousness of the issue. No heat in winter is urgent. A dripping faucet is less so. Ignoring serious repair requests or dragging them out can give tenants certain legal remedies, which is why documenting response and repair efforts is important.

Finally, lease language cannot waive habitability obligations. A lease can assign certain minor maintenance tasks to tenants, but it cannot shift core health and safety responsibilities away from the landlord. If a lease clause conflicts with habitability requirements, the law wins.

Most landlord-tenant repair disputes aren’t about bad intentions. They’re about misunderstandings — what’s required, what’s optional, and who is responsible when something breaks. Knowing the difference helps owners protect themselves and manage expectations.
