Electric space heaters are allowed in most apartments, but whether space heaters are allowed in apartments in your specific case depends on your lease, your local fire code, and your landlord’s insurance requirements. Fuel-burning heaters — kerosene and propane models — are a different matter and are banned outright in many places. If your lease says nothing about heaters at all, silence is not permission.
Check Your Lease First
The lease is the fastest way to a definitive answer. Landlords who ban space heaters usually say so under a heading like “Prohibited Items” or “Rules and Regulations.” Some leases skip the specific mention and instead ban any unapproved high-wattage appliance, which a 1,500-watt portable heater clearly is.
If the lease is silent, don’t assume you’re clear. Local fire codes still apply, and your landlord may have unwritten policies driven by their insurance carrier. Ask in writing. An email or text creates a record; a verbal “sure, go ahead” is worth very little if a fire inspector later finds the heater or your landlord changes their story.
Electric Heaters vs. Fuel-Burning Heaters
Not every space heater carries the same legal baggage. Electric heaters — ceramic, oil-filled radiator, infrared — are the type most landlords will consider allowing. They produce no combustion byproducts and no carbon monoxide.
Kerosene and propane heaters are classified as unvented combustion appliances. They release carbon monoxide, nitrogen dioxide, and other gases directly into the room where they are running. The National Fuel Gas Code prohibits installing unvented combustion heaters in bedrooms and bathrooms, and many states and municipalities have banned them from residential buildings entirely.1Building America Solution Center.

For an apartment, stick with electric. Fuel-burning heaters in a multi-family building are a non-starter in most places.
Fire Codes That Apply Regardless of Your Lease
Even a permissive lease can’t override local fire codes. NFPA 1 (the Fire Code) and NFPA 101 (the Life Safety Code), widely adopted by states and municipalities, prohibit unvented fuel-fired heaters in numerous building types unless the units comply with NFPA 54.3National Fire Protection Association. NFPA 1 – A Summary of Requirements for Heating Appliances In residential board and care occupancies, unvented fuel-fired heaters are banned regardless of compliance with any standard.
Electric space heaters face fewer code restrictions, but clearance from combustibles and proper electrical connections apply everywhere. Your local fire marshal’s office can confirm which codes govern your building.
Why Landlords Prohibit Space Heaters
Portable heater fires accounted for only 3% of residential heating fires between 2017 and 2019, but they caused 41% of fatal heating fires — an average of 65 deaths a year.4USFA.FEMA.gov. Portable Heater Fires in Residential Buildings (2017-2019) Those 1,100 annual fires also caused an estimated $51 million in property damage. The two biggest causes were heaters placed too close to combustibles and units left running unattended.
Insurance drives the rest. A fire in one apartment can spread to neighboring units and common areas, creating heavy liability exposure. Many property insurance policies raise premiums when tenants use space heaters or require landlords to prohibit them as a condition of coverage. Banning one appliance category is a straightforward way for a landlord to keep insurance costs down.
If Your Apartment Is Too Cold
This is the situation behind most space heater questions: the apartment is cold, the landlord hasn’t fixed the heat, and you need to stay warm. The legal picture is more nuanced than “my heat doesn’t work, so anything goes.”
Most jurisdictions require landlords to maintain indoor temperatures between roughly 66°F and 68°F during heating season as part of the implied warranty of habitability. In federally assisted public housing, HUD guidance sets the floor at 68°F when the housing authority controls the heat, and requires resident-controlled systems to be capable of reaching at least 68°F.
If your landlord fails to provide adequate heat, several remedies may be available depending on where you live:
- Notify the landlord in writing. Most states require this first step before any other remedy is available.
- Repair and deduct. In many states, if the landlord doesn’t act within a reasonable time after notice, you can arrange the repair yourself and deduct the cost from your next rent payment.
- Rent withholding. Some jurisdictions allow you to withhold rent entirely until heat is restored.
- Code enforcement. Local housing inspectors can compel the landlord to act.
Running a space heater as a stopgap while pursuing these remedies is a gray area. A tenant whose pipes are about to freeze has a reasonable argument for temporary supplemental heat. That argument weakens if the lease explicitly bans heaters and you never notified the landlord about the failure. Document everything: the temperature in the apartment, your written requests, and any response.
Asking for a Space Heater as a Disability Accommodation
If you have a disability that makes you more sensitive to cold — certain circulatory conditions, nerve disorders, or autoimmune diseases, for example — you may be able to request permission to use a space heater as a reasonable accommodation under the Fair Housing Act, even where the lease prohibits them. Federal regulations make it unlawful for a housing provider to refuse a reasonable change in rules, policies, or practices when the change is necessary to give a person with a disability equal opportunity to use and enjoy their home.5eCFR. 24 CFR 100.204 — Reasonable Accommodations
You’ll need documentation from a medical provider explaining the disability-related need. The landlord cannot simply say no because the lease bans heaters; they are required to engage in an interactive process to determine whether allowing the heater, possibly with safety conditions attached, is reasonable. They can deny the request only if granting it would create an undue financial or administrative burden or fundamentally alter the housing operation. For a single electric appliance with modern safety features, that bar is hard to clear.
Safety Rules When Heaters Are Allowed
Whether the landlord permits heaters by default or has granted you specific approval, the same rules apply. Ignoring them can void your insurance and leave you personally liable for damage.
Certification and Built-In Safety Features
Only use a heater that carries a label from a nationally recognized testing laboratory such as UL, ETL, or CSA. That label means the design has been independently tested for electrical safety and fire resistance. Look for two non-negotiable features: an automatic tip-over switch that cuts power if the unit is knocked over, and overheat protection that shuts the heater off if internal temperatures climb too high. Oil-filled radiator models are often preferred by landlords because their sealed surfaces don’t reach the temperatures of exposed ceramic or coil elements.
Placement and Power
Keep the heater at least three feet from anything that can burn: curtains, bedding, furniture, clothing, paper.6CPSC.gov. Tips for Using Generators, Furnaces and Space Heaters That three-foot clearance is the standard referenced across NFPA fire codes and CPSC safety guidance.7National Institutes of Health. Administrative Interpretation 17-7 Portable Space Heaters In a small bedroom, three feet in every direction is a lot of space. Measure before you buy.
Plug the heater directly into a wall outlet. Never use an extension cord or power strip. Power strips are not built for the sustained high-wattage draw of a space heater, and extension cords are one of the most common causes of electrical fires. If the only available outlet is across the room, move the heater.
What Happens If You Break a Space Heater Ban
If your lease prohibits space heaters and you use one anyway, consequences escalate in a predictable pattern. The landlord usually starts with a written warning, often called a Notice to Cure, giving you a set number of days — often a few days to a week, depending on the jurisdiction — to remove the heater.
If you ignore that notice, the landlord can impose fines when the lease provides for them, or begin eviction proceedings. Using a banned appliance after a cure notice is generally treated as a material breach, which gives the landlord grounds to terminate the tenancy. Courts routinely uphold evictions for repeated fire-safety violations.
Financial Liability If Something Goes Wrong
The real exposure comes if the heater causes a fire. You can be held responsible for damage to your own unit, neighboring units, common areas, and the building’s structure. The numbers add up quickly. Portable heater fires caused an estimated $51 million in annual property damage nationally between 2017 and 2019.4USFA.FEMA.gov. Portable Heater Fires in Residential Buildings (2017-2019)
The landlord’s insurer may cover the building damage initially and then pursue you through subrogation, stepping into the landlord’s shoes to recover what they paid. Whether an insurer can subrogate against a tenant varies by state, but the risk of a five- or six-figure judgment is real.
Why Renter’s Insurance Matters Here
If you’re using a space heater at all — explicitly allowed or in a gray area — renter’s insurance is not really optional. A standard policy includes personal liability coverage, which can help pay for damage to the building or neighboring units if you’re found responsible for an accidental fire. It also typically covers your own belongings destroyed in the fire and your legal defense costs if you’re sued.
Coverage is inexpensive relative to the exposure. Check the policy’s liability limit and confirm it’s adequate for your building. A $100,000 limit is standard, but in a large complex where a fire could reach several units, that ceiling may not be enough.
