If you have no heat in your California apartment, your landlord is legally required to fix it: state law treats a working heater as a basic condition of any rental, and your heating system must be able to hold at least 70°F in every habitable room, measured three feet above the floor. If the landlord won’t act after you’ve given notice, you have several remedies, from hiring a repair yourself and deducting the cost from rent to moving out without further obligation.
What Your Landlord Legally Owes You
Every residential lease in California carries an implied warranty of habitability. It exists automatically, and no lease language can waive it. California Civil Code 1941.1 lists heating facilities among the conditions a livable dwelling must have, and it requires those facilities to be maintained in good working order for the entire tenancy, not just at move-in.1California Legislative Information. California Code Civ 1941.1 – Condition of Premises
The temperature standard comes from the state’s building regulations. Your heating equipment must be capable of maintaining a room temperature of at least 70 degrees Fahrenheit, measured three feet above the floor, in all habitable rooms. When the landlord controls the heating system rather than the tenant, the landlord has to actually deliver that heat around the clock. Unvented fuel-burning heaters are prohibited in rental dwellings.2Cornell Law School. Cal Code Regs Tit 25, 34 – Heating
One exception matters: the landlord isn’t responsible for heating damage caused by you or your guests. Normal wear, aging equipment, and system failures stay the landlord’s problem.
Notify the Landlord and Document Everything
Before you can use any of California’s tenant remedies, you have to tell the landlord about the problem and give them a chance to fix it. Notice can be verbal, but written notice is worth the effort because it creates a record.
Send a letter by certified mail with return receipt, or email with delivery confirmation. Include the date, your name and address, a clear description of the heating failure, and a request that repairs be made promptly. Keep a copy.
Then build a file. Log each conversation with dates and what was said. Photograph the broken heater and the thermostat. A temperature log showing indoor readings at different times of day is strong evidence, especially in cold weather when the gap between your apartment and the 70-degree standard is largest.
How Long the Landlord Has
California law uses the phrase “reasonable time” rather than a fixed deadline. Under Civil Code 1942, a tenant who waits at least 30 days after notice is presumed to have given a reasonable amount of time, but the statute expressly allows the tenant to act sooner when circumstances demand it.3California Legislative Information. California Civil Code 1942
A dead heater in winter is exactly that kind of circumstance. Courts and local agencies often treat heating failures in cold weather as emergencies requiring action within 24 to 72 hours, not 30 days.
Your Remedies When the Landlord Won’t Fix the Heat
If the landlord ignores your notice or lets the deadline slide, California gives you a stack of options. They carry different levels of risk.
Repair and Deduct
You can hire someone to fix the heater and subtract the cost from your next rent payment. Civil Code 1942 caps this at one month’s rent per repair and limits you to twice in any 12-month period.3California Legislative Information. California Civil Code 1942 Keep every receipt and invoice. If the repair costs $400 and your rent is $2,000, you’d pay $1,600 and attach your documentation.
Withhold Rent
You can stop paying rent until the landlord makes the repair. This is riskier, because the landlord may respond with an eviction lawsuit for nonpayment. Your defense would be that the heating failure was a serious breach of the habitability warranty, which makes the landlord’s demand for full rent unreasonable. Courts recognize this defense, but you have to prove both the severity of the problem and that you gave proper notice.4Justia. CACI No 4320 – Affirmative Defense – Implied Warranty of Habitability Set the withheld rent aside in a separate account so you can show good faith.
Move Out
When the lack of heat makes the apartment genuinely unlivable, you can vacate and stop paying rent. Civil Code 1942 states that if the landlord fails to repair conditions that make the dwelling untenantable after reasonable notice, the tenant may move out and “shall be discharged from further payment of rent” as of the date they leave.3California Legislative Information. California Civil Code 1942 This is sometimes called constructive eviction.
Sue in Small Claims Court
You can sue the landlord for a rent reduction covering the period without heat, reimbursement for alternative heating costs, or other damages. Individuals can file small claims cases in California for amounts up to $12,500.5California Courts. Deciding Between Small Claims and Limited Civil You don’t need a lawyer, and your documentation is your evidence.
Trigger a Rent-Collection Bar Through Code Enforcement
Under Civil Code 1942.4, a landlord cannot demand rent, collect rent, or serve a three-day pay-or-quit notice if the unit substantially lacks a habitability condition listed in Civil Code 1941.1 and a housing inspector has already given the landlord written notice of the violation. Both conditions must be met.6California Legislative Information. California Civil Code 1942.4
That’s why filing a complaint with your local code enforcement or housing inspection agency is worth doing alongside anything else you’re pursuing. The inspector’s written notice to the landlord is the second condition that switches the statute on. It also creates an official government record of the violation, which strengthens any later claim. Check your city or county’s housing department website, or call 2-1-1 for local resources.
The Landlord Cannot Retaliate
Tenants often hesitate here. You know the heater is broken, you know you have rights, and you worry the landlord will raise your rent, cut services, or evict you if you push.
Civil Code 1942.5 forbids exactly that. Within 180 days of your complaint or repair notice, the landlord cannot evict you, raise your rent, or reduce services in response. If they do, the law presumes retaliation and puts the burden on the landlord to prove a legitimate reason.7California Legislative Information. California Civil Code 1942.5
A landlord who retaliates can be liable for your actual damages plus punitive damages between $100 and $2,000 for each retaliatory act involving fraud, oppression, or malice. Any lease clause that tries to waive your anti-retaliation rights is void as a matter of public policy.7California Legislative Information. California Civil Code 1942.5
Space Heaters Are Not a Safe Long-Term Fix
While you wait for the landlord to act, a space heater is the obvious stopgap. Use it carefully. Portable electric heaters are high-wattage appliances that can ignite curtains, bedding, or clothing placed too close. The Consumer Product Safety Commission warns against running them unattended or while sleeping and advises keeping combustibles at least three feet away. Never power a space heater through an extension cord or power strip, and never run the cord under a rug.8U.S. Consumer Product Safety Commission. Reducing Fire Hazards for Portable Electric Heaters
Gas and kerosene heaters carry a separate danger. Unvented fuel-burning heaters release combustion products directly into your living space, and extended use in an enclosed apartment can build dangerous levels of carbon monoxide and nitrogen dioxide. Early symptoms mimic the flu, but exposure can become fatal. California building regulations already prohibit unvented fuel-burning heaters in rental dwellings, so if the landlord’s “fix” is to hand you a portable gas heater, that does not satisfy their legal obligation.2Cornell Law School.
