Landlords must turn on heat by a specific date that depends on your state and sometimes your city, and the temperature they must maintain is usually 68°F or higher during the day.

Heat is considered an essential service in most U.S. states, meaning your landlord is legally required to provide it during winter months. The exact date heat must be turned on, the minimum temperature required, and the hours it must run all vary by location. Some states set a firm date like October 1st; others trigger the requirement when outdoor temperature drops below a certain point. A few states leave it to local ordinance, so your city or county may have its own rules that override the state standard.

The consequence of a landlord failing to provide adequate heat is significant: you may be able to withhold rent, break your lease without penalty, or file a complaint with your local housing authority. Understanding your state's specific rules protects you from both discomfort and retaliation.

Key Takeaways

  • Most states require heat to be turned on between October 1st and November 1st, with a few exceptions that use outdoor temperature as the trigger instead.
  • The minimum indoor temperature landlords must maintain is usually 68°F during daytime hours (roughly 6 a.m. to 10 p.m.) and sometimes lower at night, though some states require 70°F or higher.
  • If your landlord does not provide adequate heat, you can document the temperature with a thermometer, take photos, and file a complaint with your local housing authority or health department.
  • Withholding rent or breaking a lease due to lack of heat is legal in most states, but you must follow your state's specific procedure to avoid being sued for non-payment.
  • Some states allow you to pay for repairs yourself and deduct the cost from rent, but this requires written notice to your landlord first and varies by location.

Heat Requirements by State and Region

The Northeast and Midwest have the strictest heat laws because winter is longest and coldest. New York requires heat to be on by October 1st and maintained at 68°F between 6 a.m. and 10 p.m., dropping to 62°F between 10 p.m. and 6 a.m. Massachusetts requires 68°F during the day and 62°F at night, starting November 1st. Illinois, Pennsylvania, and Connecticut have similar rules with dates between October 1st and November 1st.

Southern and Western states often use outdoor temperature as the trigger rather than a calendar date. California, Texas, and Florida do not set a specific October or November date; instead, the requirement kicks in when outdoor temperature drops below 55°F or 60°F for a sustained period. This means you may not need heat in December if the weather stays warm, but your landlord must provide it when ready if a cold snap arrives.

A handful of states—including some in the South—do not have statewide heat requirements and instead defer to local city or county codes. If you live in such a state, contact your city or county housing authority to learn what applies to your address. Some cities have strict rules even when the state does not.

Minimum Temperature Standards

The most common standard is 68°F during daytime hours (usually 6 a.m. to 10 p.m.) and 62°F at night. This is the rule in New York, Massachusetts, Connecticut, and several other states. A few states require 70°F or higher during the day—check your state's housing code or call your local housing authority to confirm the exact number for your location.

The temperature is measured inside your apartment or house, not outdoors. Your landlord must maintain that temperature throughout the rental unit, including bedrooms and living areas. If one room is significantly colder than others, that is still a violation. You can measure the temperature yourself with an inexpensive thermometer (under $10 at any hardware store) and document it with photos or a written log showing the date, time, and temperature.

Some states allow a small variance—for example, 2°F below the required temperature for a short period—but sustained temperatures below the legal minimum give you grounds to file a complaint. If your landlord claims the heat is on but your thermometer reads 60°F at noon, that is evidence of a violation.

What to Do If Your Landlord Does Not Provide Heat

Start by documenting the problem. Take a photo of your thermometer showing the temperature and the date. Write down the date, time, and temperature each time you measure it. Keep any text messages, emails, or notes from conversations with your landlord about the heat. This record is essential if you later need to file a complaint or defend yourself in court.

Next, notify your landlord in writing. Send an email or letter stating that the heat is not adequate, provide the temperature readings you recorded, and ask them to fix it within a reasonable timeframe (usually 24 to 48 hours for heat). Keep a copy of this notice. In most states, you must give your landlord a chance to repair the problem before you take further action.

If your landlord does not respond or does not fix the heat within the required timeframe, file a complaint with your local housing authority, health department, or building inspector. These agencies can inspect your unit, confirm the violation, and order your landlord to fix it. Some agencies can also impose fines or penalties on the landlord. Contact information for your local housing authority is usually available on your city or county government website.

Withholding Rent or Escrow Accounts

If your landlord fails to provide heat, you may have the right to withhold rent or place it in an escrow account instead of paying the landlord directly. However, the rules for doing this vary significantly by state, and doing it wrong can result in an eviction notice against you. Some states require you to notify the landlord in writing and give them a set number of days to fix the problem before you can withhold. Others require you to file a complaint with a government agency first.

A safer approach in most states is to pay rent into an escrow account held by the court or a third party, rather than straightforward refusing to pay. This shows the court that you are not avoiding rent but rather protecting your money while the problem is fixed. To set up an escrow account, contact your local housing authority or tenant rights organization for instructions specific to your state.

Do not withhold rent without understanding your state's exact procedure. If you withhold incorrectly, your landlord can file for eviction, and you may lose the case even if the heat problem is real. Call your local legal aid office or tenant rights hotline for guidance before withholding any rent.

Breaking Your Lease Due to Lack of Heat

In most states, a landlord's failure to provide adequate heat is a material breach of the rental agreement, which means you may be able to break your lease without penalty. However, you must follow your state's procedure. Typically, this means sending a written notice to your landlord describing the problem, waiting a set number of days (often 14 to 30) for them to fix it, and then providing a second notice stating that you are breaking the lease due to the unresolved violation.

Some states require you to file a complaint with a housing authority or have an inspector document the problem before you can legally break the lease. Others allow you to break the lease when ready if the heat is dangerous or makes the unit uninhabitable. The safest approach is to contact your local tenant rights organization or legal aid office before you move out, so you understand exactly what notice and documentation your state requires.

If you break your lease without following the correct procedure, your landlord may sue you for the remaining rent owed. If you follow the procedure correctly and your state allows lease-breaking for lack of heat, you should not owe additional rent after you move out.

Repair-and-Deduct Laws

Some states allow tenants to pay for heat repairs themselves and deduct the cost from rent, but this is not available everywhere and has strict requirements. States that allow this include California, Colorado, Illinois, and several others, but the rules differ. Most require you to send written notice to your landlord first, wait a set number of days (often 14 to 30), and then get a licensed contractor to do the repair. You must keep all receipts and documentation.

The deduction is usually capped at one month's rent or a percentage of rent, and you must follow the exact procedure your state requires. If you do not, your landlord can sue you for the deducted amount. Before attempting a repair-and-deduct, contact your local housing authority or tenant rights organization to confirm that your state allows it and to learn the exact steps you must follow.

Frequently Asked Questions

What temperature counts as adequate heat?

Most states require 68°F during daytime hours (6 a.m. to 10 p.m.) and 62°F at night. Some states require 70°F or higher. Check your state's housing code or call your local housing authority to learn the exact requirement for your location. Measure the temperature inside your unit with a thermometer; outdoor temperature does not matter.

Can my landlord turn off heat to save money?

No. Once the heat season begins in your state (usually October or November), your landlord must keep heat on and maintain the legal minimum temperature throughout the winter, regardless of cost. Turning off heat to reduce expenses is a violation of housing law in most states.

What if my landlord says the heat is on but my apartment is still cold?

Document the temperature with a thermometer and photos. The landlord's claim that the heat is on does not matter if the actual temperature is below the legal minimum. If the system is on but not working properly, that is still a violation. File a complaint with your housing authority and provide your temperature readings as evidence.

Can my landlord evict me for complaining about lack of heat?

No. Retaliatory eviction—evicting a tenant for reporting a housing code violation—is illegal in most states. If your landlord evicts you within a certain timeframe (often 6 months) after you file a complaint about heat, the eviction is presumed to be retaliation. Contact your local tenant rights organization if you believe you are facing retaliation.

Do I have to pay for my own space heater if the landlord's heat is inadequate?

No. Your landlord is required to provide adequate heat as part of the rental. You should not have to buy a space heater to stay warm in your own apartment. If you do buy one out of necessity while waiting for repairs, keep the receipt—you may be able to deduct the cost from rent in some states, though you must follow the correct procedure first.
