Your Landlord Must Keep Your Apartment Warm — Here's the Law
When the temperature drops, your landlord has a legal duty to keep your apartment livable — and that means heat. Most cities and states set minimum temperature requirements for rental housing, and violating them can trigger code enforcement action, rent abatement, or even lease termination. Here's what you need to know.
What Temperature Is Required by Law?
There's no single federal standard, but most jurisdictions set minimum indoor temperatures between 64°F and 68°F during heating season (typically October 1 through May 31). New York City requires 68°F during the day when outdoor temps drop below 55°F, and 62°F at night. Chicago requires 68°F during the day, 66°F at night from September 15 through June 1. Boston requires 68°F during the day and 64°F at night. Check your city's housing code — it almost certainly has a specific number.
What Counts as a Heating Violation?
If your apartment consistently falls below the minimum temperature during heating season, that's a habitability violation. It doesn't matter whether the landlord controls the boiler or you have your own furnace — if the heating system can't maintain legal minimums, the landlord must fix it. Document the temperature with a cheap indoor thermometer (the timestamped photo of the reading is your evidence). Log it for at least 3-5 days to show a pattern, not just a one-time dip.
What to Do When Your Heat Doesn't Work
Step one: notify your landlord in writing. Email or text works — you want a timestamp. Give them 24-48 hours for emergency repairs. If nothing happens, call your city's 311 line or housing inspection department to file a complaint. Many cities dispatch an inspector within 24 hours for heat complaints in winter. You can also withhold rent in some states (check your state's repair-and-deduct statute first), but never stop paying without understanding the legal process.
Can You Break Your Lease Over No Heat?
In most states, yes. A landlord's failure to provide adequate heat is a breach of the implied warranty of habitability. If you've given written notice and the problem persists for a reasonable period (usually 14-30 days depending on the state), you may have grounds for constructive eviction — meaning you can leave and stop paying rent. Document everything and consult your state's tenant rights statute before making this call.
Space Heaters and Utility Costs
If your landlord's heating system fails and you buy space heaters to stay warm, keep the receipts. In many jurisdictions, you can deduct those costs from rent or seek reimbursement. However, never use unvented gas heaters or ovens for heat — carbon monoxide poisoning kills dozens of renters every year. Stick to UL-listed electric space heaters with auto-shutoff features.
●Frequently Asked Questions
Frequently Asked Questions
Can my landlord charge me extra for heating my apartment to the legal minimum?
If heat is included in your lease, no — the landlord must provide it at no additional charge. If you pay your own utilities and have your own heating system, you're responsible for the bill, but the landlord is still required to ensure the system actually works and can reach the minimum temperature.
What if my landlord says the heat is fine but my apartment is still cold?
Buy a basic indoor thermometer (under $10) and take timestamped photos showing the reading below the legal minimum. Poor insulation, broken windows, or malfunctioning radiators are all landlord responsibilities. The reading on your thermometer, not your landlord's opinion, is what matters to a housing inspector.
How fast does my landlord have to fix a broken heater in winter?
Most cities treat winter heat failures as emergency repairs requiring response within 24 hours. Some states specify this in statute. If your landlord doesn't respond within 24 hours during freezing weather, contact your local housing authority or 311 immediately.
