Chicago is in the deep freeze.
With dangerously cold temperatures and wind chills dipping below zero, many South Side residents are bundling up, sealing windows, and cranking up the heat just to stay warm.
The extreme cold also serves as a critical reminder of Chicago’s Heat Ordinance, which legally requires landlords to provide safe indoor temperatures throughout the winter months.
The last time Chicago experienced a historic polar vortex was in 2019, when temperatures plunged to nearly -30 degrees, forcing school closures, transit shutdowns, and widespread safety warnings. While this winter may not yet match those record lows, this weekend’s arctic blast shows how quickly conditions can become dangerous, especially for seniors, children, and residents living in poorly insulated buildings.
Here’s what Chicago renters need to know about their heating rights.
What Is the Chicago Heat Ordinance?
The Chicago Heat Ordinance is a city law designed to protect tenants during cold weather by requiring landlords to provide adequate indoor heat in all residential rental units.
The ordinance is in effect every year from September 15 through June 1. This period is referred to as the “heat season.”
During this period, landlords must ensure that residential apartments and workspaces maintain minimum indoor temperatures.
Extreme cold inreases the risk of:
- Hypothermia
- Frostbite
- Respiratory complications
- Worsening chronic conditions
- Frozen pipes and water outages
For many South Side residents, especially seniors, families with young children, and people living in older buildings, reliable heat can be the difference between safety and serious health risks.
Required Indoor Temperatures
Under Chicago law, landlords must maintain:
- At least 68°F from 8:30 a.m. to 10:30 p.m.
- At least 66°F from 10:30 p.m. to 8:30 a.m.
These standards apply whenever tenants do not control their own heating system. Even in buildings where tenants have individual thermostats, landlords must ensure the heating equipment is functional, safe, and capable of maintaining legal temperatures.
What To Do If Your Apartment Isn’t Warm Enough
If your unit does not meet the required indoor temperature, you have the right to report the violation by filing a complaint with the City of Chicago.
Step 1: Call 311
- Dial 311 or submit a complaint online through the City of Chicago.
- Report no heat or inadequate heat.
Step 2: City Inspection
- The Department of Buildings will send an inspector to verify conditions.
- If violations are found, the landlord will be ordered to fix the issue immediately.
Step 3: Fines and Penalties
Landlords who fail to comply face fines ranging from $500 to $1,000 per day, per violation, until heat is restored.
Who Is Protected Under the Ordinance?
The ordinance applies to:
- Apartment buildings
- Single-family rental homes
- Multi-unit residences
- Hotel rooms
- Certain indoor workspaces, including bathrooms and common areas
Every renter in Chicago is covered.
Cold Weather Safety Tips for South Side Residents
Even when heat is working properly, extreme cold calls for extra precautions:
- Seal windows and doors with weather stripping or plastic insulation kits
- Keep cabinet doors open to prevent frozen pipes
- Drip faucets slightly during extreme cold
- Wear layers indoors
- Check on elderly neighbors and family members
- Avoid using ovens or space heaters as primary heat sources
Stay Warm, Stay Informed
As winter tightens its grip and polar vortex conditions remain a real threat, Chicago’s Heat Ordinance serves as a critical safety net for renters across the city.
If your heat isn’t working properly, call 311 immediately.
