The legal answer depends on where you live, but most places set a important date between 24 hours and 7 days
Your landlord cannot leave you without heat indefinitely. In most U.S. states, landlords must provide heat that keeps indoor temperatures at a minimum level — usually 68°F during winter months — and must fix a broken heating system within a set timeframe. That timeframe ranges from 24 hours in some states to 7 days in others, depending on your location and how cold it is outside.
The specific rules depend on your state and sometimes your city. New York requires heat within 24 hours if the outside temperature is below 55°F. Massachusetts gives landlords 24 hours in winter. Illinois allows up to 7 days. Some states have no statewide rule at all, leaving it to local housing codes or the terms of your lease. The key is that "reasonable" heat is a legal requirement, not a favor.
If your landlord misses the important date, you have options: you can withhold rent (in some states), break your lease without penalty, repair it yourself and deduct the cost from rent, or file a complaint with your local housing authority. The longer you wait to act, the weaker your position becomes.
Key Takeaways
- Most states require landlords to restore heat within 24 to 7 days, with shorter important date when outdoor temperatures drop below 55°F.
- You should document the problem by taking photos, noting the indoor temperature, and recording the date you reported it to your landlord.
- If your landlord does not fix the heat within the legal timeframe, you can withhold rent, break your lease, or file a complaint with your local housing authority without penalty.
- Sending written notice (email or certified mail) creates a record and often starts the clock on the landlord's important date.
- The rules vary significantly by state and city, so checking your local housing code is the first step to knowing your rights.
How to report the problem and start the clock
Report the broken heat to your landlord in writing — email, text, or certified mail all work. Do not rely on a phone call alone. Written notice creates a record of when you reported it and forces the landlord to acknowledge the problem. Include the date you noticed the heat was off, the current indoor temperature if you have a thermometer, and the date of your message.
Keep copies of everything: your message to the landlord, any response, photos of your thermostat or radiator, and notes on the dates and times you tried to contact them. If the landlord ignores you or misses the important date, this documentation is what you will need to prove your case to a housing authority or in court.
If your landlord claims they did not know about the problem, your written notice proves otherwise. If they say they tried to fix it but the repair took longer than the law allows, the documentation shows how long they actually took. Do not assume the landlord knows — tell them directly and in writing.
What counts as "heat" under the law
The law does not mean your apartment is warm and comfortable. It means a minimum temperature, usually 68°F indoors when it is cold outside. Some states measure this differently: New York requires 68°F between 6 a.m. and 11 p.m., and 62°F overnight. Massachusetts requires 68°F. Illinois requires 65°F. Check your state's housing code to know the exact number.
The law also usually applies only during winter months — typically October or November through April or May, depending on your state. If your heat breaks in July, the landlord may have more time to fix it because the law does not require heat in summer. But if it is winter and the heat is broken, the important date is strict.
A landlord cannot meet this requirement by providing a space heater, a fireplace, or telling you to wear more layers. The heating system itself must work. If the furnace is broken, the radiators are off, or the boiler is not functioning, the landlord must repair or replace it.
Your options if the landlord misses the important date
Withhold rent. In many states, you can stop paying rent if the landlord fails to provide heat within the legal timeframe. This is called a "repair and deduct" or "rent withholding" remedy. You do not keep the money — you set it aside in a separate account and show the landlord you have done so. If the case goes to court, the judge will decide whether the landlord's failure was serious enough to justify withholding. Document everything: the date the heat broke, the date you reported it, the date the important date passed, and the date it was finally fixed.
Break your lease. In most states, a landlord's failure to provide heat is a material breach of the lease. You can move out without penalty and without owing the rest of the rent. Again, documentation is critical. Send the landlord a final written notice saying the heat is still broken, the important date has passed, and you are breaking the lease as of a specific date. Keep a copy.
Repair it yourself and deduct the cost. Some states allow tenants to hire a contractor to fix the heat and subtract the repair bill from the next month's rent. This only works if you follow the law: you must give the landlord written notice and a reasonable chance to fix it first, then get a written estimate, do the repair, and keep the receipt. The deduction cannot exceed one month's rent in most states.
File a complaint with your housing authority. Your city or county housing authority can inspect the apartment, document the violation, and order the landlord to fix it. This does not get your heat fixed faster, but it creates an official record and can result in fines or penalties against the landlord. Some housing authorities can also order the landlord to pay you compensation for the period without heat.
State-by-state heat important date
The rules vary widely. Here are some common examples:
| State | Minimum Temperature | Repair important date | Winter Season |
|---|---|---|---|
| New York | 68°F (6 a.m.–11 p.m.); 62°F (11 p.m.–6 a.m.) | 24 hours if outdoor temp below 55°F | Oct. 1 – May 31 |
| Massachusetts | 68°F | 24 hours | Nov. 1 – May 31 |
| Illinois | 65°F | 7 days (or 24 hours if below 32°F outside) | Sept. 15 – June 1 |
| California | No statewide minimum | Varies by city; often "reasonable time" | Varies |
| Texas | No statewide requirement | Varies by city | No statewide requirement |
If your state is not listed, search "[your state] landlord heat requirements" or contact your local housing authority. Many cities have stricter rules than the state, so check both.
What usually goes wrong and how to protect yourself
Landlords often claim they did not know the heat was broken. This is why written notice matters. A text message, email, or certified letter with a read receipt proves you told them. If you call and they do not respond, follow up in writing the same day.
Landlords also sometimes delay by saying the repair company is booked or the part is on backorder. The law does not care. The landlord is responsible for getting it fixed on time, even if that means paying for emergency service or a rush order. If the important date passes, the delay is the landlord's problem, not yours.
Another common issue: tenants wait too long to act. If you go two weeks without heat and then complain, the landlord may argue you accepted the condition. Report it when ready, in writing, and keep pushing. The sooner you document the problem, the stronger your case.
Frequently Asked Questions
Can my landlord evict me for withholding rent because there is no heat?
No. In most states, evicting a tenant for withholding rent due to a serious repair failure is illegal retaliation. The landlord must fix the heat first. If the landlord tries to evict you, you can raise the heat failure as a defense in court. Document everything to prove the heat was broken and the landlord missed the important date.
What if my landlord says the heat is my responsibility because I rent a room, not a whole apartment?
The landlord is still responsible. Even if you rent a single room in a shared house, the landlord must provide heat that meets the legal minimum. The fact that you do not rent the whole building does not change that. Report it in writing and follow the same steps as a full apartment tenant.
Do I have to pay rent while the heat is broken?
That depends on your state and how long the heat has been off. In states that allow rent withholding, you can stop paying once the landlord misses the important date. In other states, you must keep paying but can sue the landlord for damages. Check your state's rules before you stop paying, and always set the money aside in a separate account rather than spending it.
How do I prove the heat was actually broken?
Take photos of your thermostat showing the temperature, write down the date and time you noticed it, and keep any messages you sent to the landlord. If possible, use a separate thermometer to record the indoor temperature. If a repair person comes to fix it, ask for a receipt that shows what was wrong and when it was repaired. All of this is evidence.
What if I live in a state with no heat requirement?
Some states have no statewide rule, but most cities do. Check your city or county housing code. If there is truly no local rule either, your lease may require the landlord to provide heat anyway. If the lease is silent and there is no local law, you may have limited options, but you can still break the lease if the lack of heat makes the apartment uninhabitable. Consult a local tenant rights organization or legal aid office.
