California Civil Code 1941 requires every residential landlord to put and keep the rental in a condition fit for human living. The companion statute, Section 1941.1, defines what “fit for human living” means through a specific checklist of features, and Sections 1942 through 1942.5 give you concrete tools when your landlord ignores the problem: fix it yourself and deduct the cost, withhold rent, move out without further obligation, call in code enforcement, or sue for damages. The same chapter makes it illegal for a landlord to retaliate against you for using any of these rights.
What Your Landlord Must Provide
A rental is legally untenantable if it substantially lacks any feature on the Section 1941.1 list. “Substantially” is doing real work in that sentence. A dripping faucet does not qualify. A broken water heater that leaves you with no hot water almost certainly does.
The baseline requirements are:
- Waterproof roof, exterior walls, windows, and doors
- Plumbing and gas systems in good working order, meeting the code in effect when installed
- Hot and cold running water connected to a code-compliant sewage system
- A working heating system (California does not require air conditioning statewide, but it does require heat)
- Functional lighting and electrical wiring that met code at installation
- Building, grounds, and common areas kept clean and free of debris, rodents, and vermin
- An adequate number of garbage and recycling receptacles, maintained by the landlord
- Floors, stairs, and railings kept in good repair
- A locking mailbox in residential hotels
Section 1941.1 also pulls in every condition defined as “substandard” under Health and Safety Code Sections 17920.3 and 17920.10, which widens the list considerably.1California Legislative Information. California Code CIV 1941.1 – Tenantability of Dwelling
Stoves and Refrigerators Starting in 2026
For any lease signed, amended, or extended on or after January 1, 2026, the landlord must provide a working stove that safely generates heat for cooking and a working refrigerator that safely stores food. A recalled appliance does not meet the standard. You and the landlord can agree in writing that you will supply your own refrigerator, but the lease has to include a specific disclosure acknowledging that choice.1California Legislative Information. California Code CIV 1941.1 – Tenantability of Dwelling
Where Mold Fits In
The word “mold” does not appear in Section 1941.1 itself. It enters through the cross-reference to Health and Safety Code Section 17920.3. Since January 1, 2016, visible mold growth that endangers occupants makes a building legally substandard, with a narrow exception for minor mold on surfaces that normally get wet by design (the edge of a shower door, for example). Dampness in habitable rooms is a separate substandard condition under the same code.2California Department of Public Health. Mold Significant mold is therefore a valid basis for a habitability claim under Section 1941.

What You Owe in Return
Habitability runs both ways. Section 1941.2 requires tenants to keep their portion of the unit clean and sanitary, operate plumbing, gas, and electrical fixtures properly, dispose of waste sanitarily, avoid willfully damaging the dwelling, and use rooms only for their intended purpose. If a problem traces back to your own neglect or misuse, the landlord is not responsible for fixing it and the self-help remedies below are off the table.
Repair and Deduct
Section 1942 lets you fix a habitability problem yourself and subtract the cost from your next rent payment. The remedy is powerful, and it has three limits that trip up tenants who don’t know about them.
You have to notify the landlord of the specific problem, in writing or verbally, and give a reasonable time to fix it. Thirty days after notice is presumed reasonable. You can act sooner when circumstances demand, like a broken front door lock in a high-crime area, but you carry the burden of showing the shorter timeline was justified.4California Legislative Information. California Code CIV 1942
The cost you deduct cannot exceed one month’s rent. If rent is $2,000, that’s your ceiling on a single repair. Anything more expensive requires a different approach.
You can only use this remedy twice in any 12-month period. After the second deduction within a year, the statute cuts you off from further self-help repairs no matter what new problems appear.4California Legislative Information. California Code CIV 1942
Keep receipts for every repair, photograph the condition before and after, and save your written notice to the landlord. If the landlord later disputes the deduction, that paper trail is your defense.
Withholding Rent
Repair and deduct was built for smaller problems like a broken garbage disposal or a bad light fixture. For serious defects that make the unit substantially uninhabitable, the broader remedy comes from the implied warranty of habitability recognized by the California Supreme Court in Green v. Superior Court (1974). Every residential lease in California carries an implied promise to maintain habitable conditions throughout the tenancy, and a breach of that promise is a defense to an eviction for nonpayment of rent.5Justia. Green v. Superior Court
In practice: notify the landlord of the serious defect, give a reasonable time to repair, and if nothing happens, withhold some or all of the rent until it’s fixed. The important word is “some.” Courts look at how much of the unit’s value was actually impaired. A January with no heat is a bigger loss of habitability than a stuck window, and the permissible withholding reflects that.
The risk is real. If a court later decides the defect didn’t justify withholding, or that your notice was inadequate, an eviction judgment for unpaid rent can follow. Document the condition with photographs, keep written complaints, log the landlord’s responses, and save anything from a building inspector.
Moving Out Without Further Obligation
Section 1942 also lets you vacate when the landlord fails to repair untenantable conditions. Once you leave, you are discharged from all future rent and other lease obligations as of your move-out date.4California Legislative Information. California Code CIV 1942 The same notice-and-reasonable-time rule applies: tell the landlord first, give a fair chance to repair.
Related but distinct, the doctrine of constructive eviction applies when a landlord’s action or inaction so severely interferes with your use of the home that it amounts to being evicted. Severe pest infestations, failure to provide heat, and preventing a tenant from obtaining electricity have all qualified. A constructively evicted tenant owes no further rent, but you must actually vacate within a reasonable time after the landlord fails to resolve the problem. Staying put, enduring the conditions, then later claiming constructive eviction does not work.
Code Enforcement and the 35-Day Rule
You do not have to handle this alone. California’s Attorney General recommends contacting your local code enforcement office, building department, or health department to report unsafe or unhealthy conditions. If you’re not sure who to call, 211 (or 311 in some cities) can point you to the right agency. The inspector will visit and order the landlord to repair any violations found.6California Attorney General. Know Your Rights – Habitability
When conditions threaten immediate health or safety, the city or county may require you to leave. In that situation, the landlord can be required to pay your relocation costs. Ask the code enforcement office about relocation benefits right away if you get such a notice.
A code inspection also unlocks a sharper legal tool. Under Civil Code Section 1942.4, once an inspector has given the landlord written notice of substandard conditions and 35 days pass without good cause for the delay, the landlord loses the right to collect rent, raise rent, or serve a three-day pay-or-quit notice while the violation continues. If the landlord tries to evict anyway, the court can award you attorney’s fees.7California Department of Real Estate. Tenant’s Responsibility for Repairs
Suing for Damages
When informal remedies fail, you can sue for breach of the warranty of habitability. Recoverable damages include the difference between what you paid in rent and what the unit was actually worth in its defective state, out-of-pocket costs for temporary housing or repairs, property damage caused by the defect, and compensation for the discomfort and inconvenience of living in substandard conditions. A court can also order the landlord to make specific repairs.
Under Section 1942.4, a tenant who meets the inspection, written notice, and 35-day cure requirements, and whose conditions were not self-inflicted, can recover actual damages plus a civil penalty of up to $2,000 for each violation.7California Department of Real Estate. Tenant’s Responsibility for Repairs
Protection From Retaliation
Many tenants put up with dangerous conditions because they expect the landlord to raise the rent or start an eviction the moment they complain. Civil Code Section 1942.5 makes that illegal.
After you give notice of a habitability problem, file a complaint with a government agency, report a bed bug infestation, or file a legal proceeding about tenantability, your landlord cannot evict you, raise your rent, or cut services for 180 days. The clock runs from whichever triggering event happened most recently.8California Legislative Information. California Code CIV 1942.5
If retaliation happens anyway, you can sue for actual damages plus punitive damages of $100 to $2,000 for each retaliatory act involving fraud, oppression, or malice. The court must award reasonable attorney’s fees to the prevailing party, which gives tenants real leverage to bring these claims and discourages frivolous landlord filings.8California Legislative Information. California Code CIV 1942.5
You can invoke the 180-day presumption only once in any 12-month period. That does not strip your protection after one complaint. It means the statutory presumption resets annually, and genuinely retaliatory conduct remains actionable regardless of timing.
