When do landlords have to turn the heat on in NJ (NJ Heating Laws 2026)

If you’re a renter in New Jersey, one of the most common questions is:
👉 “When are landlords required to turn on the heat?”
In New Jersey, the answer is clear — landlords must provide safe and functional heat during the heating season. But the exact requirements can depend on city regulations, building type, and whether the heating system is tenant-controlled.
Here’s what you need to know.

1. New Jersey’s Heating Season: When Must Heat Be On?In New Jersey, landlords must provide heat during the heating season, which is typically:
🔹 October 1 to May 1During this time, landlords must ensure the property has a working heating system.
What this means:If your heat is not working between October 1 and May 1, your landlord may be violating NJ housing laws.

2. Required Indoor Temperatures (NJ Housing Standards)NJ requires landlords to maintain a minimum indoor temperature, usually:
At least 68°F (20°C)when the outdoor temperature is below 55°F (13°C)
If your apartment falls below this level, your landlord must address it.

3. When Landlords Must Turn Heat On (Time of Day Rules)In many NJ cities, landlords are required to keep heat on:
🔸 From 6:00 AM to 10:00 PMor 24 hours a day in some cases.
This ensures tenants have access to heat during the coldest parts of the day.

4. What If the Heat Breaks Down?If the heat stops working during the heating season, landlords must:
✔️ Repair it promptly✔️ Provide temporary heat if needed✔️ Ensure the tenant’s safety and comfortLandlords cannot simply ignore the issue until the next scheduled service.

5. Tenant-Controlled Heat: Who Pays?Some buildings have tenant-controlled heat (like individual heaters or baseboard systems).
In those cases:
✔️ The landlord is responsible for ensuring the system works✔️ The tenant is responsible for paying for energy usage✔️ The landlord may not be required to provide heat if the tenant turns it off
6. What If the Landlord Refuses to Turn on the Heat?If your landlord refuses to provide heat during the heating season, tenants can:
🔹 File a complaint with the local housing authority🔹 Request an inspection🔹 Pursue legal action for uninhabitable living conditionsNew Jersey takes heat laws seriously because lack of heat can be dangerous.

7. New Jersey Cities With Specific Heating RequirementsSome NJ cities have additional rules. For example:
PatersonLandlords must maintain safe heat and ensure units meet local codes.
Newark, Jersey City, and HobokenOften have stricter enforcement and additional local requirements.
If you live in a city with stricter rules, your landlord may be required to provide heat more consistently.

8. How Landlords Must Maintain Heat SystemsLandlords are responsible for:
✔️ Annual maintenance of the heating system✔️ Safe installation and proper ventilation✔️ Repairing broken furnaces, boilers, or heat pumps✔️ Ensuring carbon monoxide detectors are installed (where required)This is crucial for tenant safety and compliance with NJ laws.

9. What Tenants Should Do If Heat Is Not WorkingIf your heat is not working, follow these steps:
1. Notify your landlord in writingKeep a copy for records.
2. Document the temperatureUse a thermometer to show it’s below 68°F.
3. Request repairs immediatelyAsk for a repair timeline.
4. Contact local housing authoritiesIf the landlord does not respond.
