The heat is off. Now what?

Maybe it's January and your radiator hasn't clicked on in two weeks. Maybe there's a leak above your bathroom that's been "getting looked at" since September. Whatever the failure, most Chicago renters hit the same wall: they know something is wrong, but they have no idea where to send it.

There are actually several channels, and picking the right one matters.

Start with 311

For most habitability issues — no heat, broken plumbing, pest infestation, structural hazards — 311 is your first call or click. You can file online at 311.chicago.gov, by phone, or through the CHI311 app. Be specific: unit number, nature of the problem, how long it's been ongoing. Vague complaints take longer and give landlords more room to wiggle.

Once your complaint is logged, it routes to the Chicago Department of Buildings (CBS), which can dispatch an inspector to your unit. You'll get a service request number — keep it. That number is your paper trail.

If your landlord is retaliating or you need legal footing

Chicago's Residential Landlord and Tenant Ordinance (RLTO) gives renters real teeth: the right to withhold rent, repair-and-deduct, or terminate a lease if conditions aren't remedied in time. RLTO enforcement isn't a hotline you call — it's a framework you invoke, usually with documentation from that CBS inspection in hand. The Chicago Lawyers' Committee and Metropolitan Tenants Organization both offer free guidance on RLTO claims if you need a next step.

Other agencies worth knowing

- Chicago PD — relevant if a habitability issue crosses into harassment or illegal lockout territory.
- City Scavenger — handles garbage and sanitation complaints, including overflowing dumpsters or missed pickups that create health conditions.
- Cook County — steps in for issues involving court-ordered actions, like buildings under receivership.

A few things that actually help your case

Take dated photos the day you notice a problem. Send written notice to your landlord via email so there's a timestamp. Note if neighbors have the same issue — patterns of neglect carry weight in any enforcement review.

Filing a complaint is not picking a fight. It's using a system that exists precisely for this. Chicago built these channels because tenant-landlord disputes are older than the city's building code — and a written record is the only thing that makes them resolvable.
