Chicago winters are brutal—temps regularly drop below zero. No heat isn't just uncomfortable, it's dangerous. Fortunately, Chicago has clear laws about what temperatures landlords must maintain. Here's what you need to know.

No Heat Right Now?

Call 311 immediately to report a heat complaint. Chicago takes these seriously.

For life-threatening emergencies (elderly, infants, medical conditions), call 911.

Heat Requirements

Chicago law requires landlords to provide heat during "Heating Season"—September 15 through June 1. The requirements are:

Legal Temperature Requirements

Unlike heat, hot water is required 365 days per year, 24 hours a day.

Hot Water Requirements

Minimum temperature at tap120°F

Must be available at all times, year-round

Heat Season Dates

September 15 — June 1

Heat Violations Are Serious

  • Court action — Tenants can sue for damages

Check Building's Heat Complaint History

Before renting, see if a building has repeated heat violations. Multiple heat complaints = cold winters.

Your Rights Under the RLTO

If your landlord fails to provide heat, you may have remedies under the RLTO:

  • Repair and deduct — After proper notice, you may be able to fix the issue and deduct from rent
  • Rent withholding — In extreme cases (consult a lawyer first)
  • Lease termination — Serious violations may allow you to break the lease

Important

Before using RLTO remedies, consult with a tenant rights organization or attorney. Contact the Metropolitan Tenants Organization at (773) 292-4988.

Common Questions

What if my landlord says the boiler is broken?

Not an excuse. Landlords are responsible for maintaining heating systems. Boiler problems must be fixed immediately—they can't just leave you without heat.

What if I control my own heat (electric baseboard)?

If you have individual heating and pay your own electric bill, the landlord may not be responsible for providing heat—but they must ensure the system works properly.

Can I use a space heater?

As a temporary solution, yes—but your landlord is still required to provide adequate heat. Space heaters can be fire hazards, so be careful.

What about summer? Can my apartment be too hot?

Chicago has no maximum temperature requirements and landlords aren't required to provide air conditioning. However, they can't prevent you from installing a window AC unit.
