Green v. Superior Court (1974) 10 Cal.3d 616; Cal. Civ. Code §§ 1941, 1941.1, 1942; CACI No. 4350
The implied warranty of habitability: a landlord cannot contract out of it
A claim in California superior courts · Last verified August 26, 2026
Until 1974, a California tenant's obligation to pay rent had nothing to do with the landlord's obligation to maintain the building. The lease was a conveyance of land; you took the property as you found it; and a tenant living without heat still owed every dollar.
Green v. Superior Court (1974) 10 Cal.3d 616 ended that. Every residential lease now carries an implied warranty of habitability, and the tenant's duty to pay rent is dependent on the landlord's duty to maintain the premises.
It cannot be waived. A lease clause purporting to disclaim it is void as against public policy, and that is true no matter how clearly it is written or how much rent was reduced in exchange.
What the claim is
Your landlord failed to maintain the rental in a condition fit for human occupancy, and you were harmed — in the value of what you paid for, in your property, or in your health.
The recurring conditions: no heat; no hot or cold running water; plumbing or sewage failures; a roof or windows that do not keep out the weather; broken doors or locks; electrical hazards; rodent, roach, or bed bug infestation; mould; structural instability; accumulated garbage.
Where the right comes from
Judicial, in Green, layered over an older statutory scheme.
Civil Code § 1941 obliges a landlord of a residential dwelling to put and keep it in a condition fit for human occupancy. Section 1941.1 lists the characteristics that make a dwelling untenantable — effective waterproofing, plumbing in good working order, a hot and cold water supply, heating facilities, electrical lighting and wiring, clean and sanitary grounds free of vermin, adequate garbage receptacles, and floors, stairways, and railings maintained in good repair.
Section 1942 supplies repair and deduct. Section 1942.4 bars a landlord from demanding or collecting rent in specified circumstances. Section 1942.5 protects against retaliatory eviction.
Section 1942.1 makes the warranty non-waivable — an agreement by the tenant to modify or waive the rights under §§ 1941 or 1942 is void as contrary to public policy.
What a plaintiff has to prove — CACI No. 4350
- The plaintiff rented a dwelling from the defendant.
- The dwelling had a condition that made it untenantable.
- The defendant had notice of the condition, or the condition existed long enough that the defendant should have known.
- The defendant failed to repair it within a reasonable time after notice.
- The plaintiff was harmed, and the failure to repair was a substantial factor.
Element three is where these cases turn. The landlord must have had actual or constructive notice. A tenant who never reported a condition the landlord could not have known about will generally lose — which is why written complaints, dated photographs, and code enforcement records matter more than anything else in the file.
The defect must be substantial. The warranty covers conditions affecting habitability, not cosmetic or minor ones. A cracked tile is not a breach; no hot water is.
And the tenant's own conduct matters. The warranty is not breached where the tenant, their family, or their guests caused the condition, or where the tenant refused reasonable access for repairs.
Two ways it comes up — and this page is about the first
As an affirmative claim, brought by a tenant seeking damages. CACI No. 4350.
As a defense in an unlawful detainer for nonpayment of rent. CACI No. 4320. Because the duties are dependent, a tenant sued for possession may answer that the rent was not owed in full. That is the Green holding in its original form, and it is covered on the unlawful detainer page.
The affirmative claim survives the tenancy. A tenant who moved out, or who was evicted, can still sue for the period they lived in substandard conditions.
How long you have to file
It depends on the theory, and a tenant should identify all of them:
Four years on a written lease, under CCP § 337 — the warranty is implied into the contract, so a breach of it is a breach of the lease.
Two years on an oral lease, under CCP § 339.
Three years for injury to personal property damaged by the condition, under CCP § 338.
Two years for personal injury, under CCP § 335.1 — which is the period that governs a mould, vermin, or lead exposure claim, and the shortest of the set.
A continuing breach gives rise to continuing damages, so a condition that persisted for years generally supports recovery for the portion within the applicable period rather than being barred outright.
What has to happen before you file
Nothing, to sue.
But repair and deduct has its own conditions, and they are strict. Under Civil Code § 1942, a tenant may repair the condition and deduct the cost from rent only if:
- the landlord had notice and a reasonable time to repair — presumed to be 30 days, though a shorter period may be reasonable depending on the severity;
- the cost does not exceed one month's rent; and
- the remedy is used no more than twice in any 12-month period.
Character: conditions on a self-help remedy, not a gate on the lawsuit. A tenant who repairs and deducts outside these limits has not lost their claim — they have underpaid rent and exposed themselves to an unlawful detainer.
Rent withholding is riskier and has no statutory safe harbour. A tenant who withholds rent entirely is betting that a court will later find the breach substantial enough to justify it. If the tenant is wrong, they are subject to eviction. Withholding is a defense to be proved, not a right to be exercised.
Section 1942.4 is the exception that gives it teeth. A landlord may not demand or collect rent where the dwelling substantially lacks a § 1941.1 characteristic, a public officer has notified the landlord of the violation, the conditions were not caused by the tenant, and the landlord failed to correct them within 35 days.
Who can be sued — and who can sue
The landlord, and generally the property owner, whether or not they manage the building.
A property management company acting as agent may be liable.
Any residential tenant may sue, including one whose tenancy has ended. Occupants who are not tenants — family members, guests — have no contract claim but may have a negligence claim for personal injury.
Commercial tenancies are excluded. The implied warranty of habitability is a residential doctrine.
Common defenses
The condition was not substantial enough to affect habitability.
No notice, actual or constructive — the leading defense.
A reasonable time to repair had not passed.
The tenant caused the condition, or refused access.
The tenant waived it — which fails, because § 1942.1 makes waiver void.
The limitations period, on whichever theory.
Retaliation is not available as a defense to the landlord — it runs the other way. Civil Code § 1942.5 creates a presumption of retaliation where a landlord raises rent, decreases services, or seeks to evict within 180 days of the tenant exercising habitability rights, and it carries its own damages and fee award.
What the claim pays
Rent abatement — the difference between the rent paid and the reasonable rental value of the premises in their defective condition. This is the core measure and it is retrospective: a tenant who paid full rent for two years in a substandard unit recovers the difference.
Discomfort and annoyance damages, for the loss of habitability itself.
Personal injury damages, where the condition caused illness or injury.
Damage to personal property.
Emotional distress damages are available where the breach was accompanied by tortious conduct; a bare contract breach generally does not support them.
Punitive damages under Civil Code § 3294 on clear and convincing proof of oppression, fraud, or malice — available where a landlord knew of serious conditions and refused to act, which is the category of case that produces large verdicts.
Statutory damages under § 1942.4, plus attorney's fees and costs to a prevailing tenant under that section, in addition to actual damages.
Fees under the lease, and Civil Code § 1717 makes a one-sided fee clause mutual — so a lease drafted to give the landlord fees gives them to a prevailing tenant too.
Jury trial: yes.
What people get wrong
"I signed a lease saying I take it as is." That waiver is void. Civil Code § 1942.1 makes the warranty non-waivable.
"I kept paying rent, so I've accepted it." Paying rent does not waive the claim. You recover the difference between what you paid and what the unit was worth.
"I can just stop paying rent." You can, but there is no statutory protection for it. Withholding is a defense you must later prove, and if the court disagrees you are evicted.
"I'll repair it and deduct whatever it costs." Only up to one month's rent, only after notice and a reasonable time, and only twice in twelve months.
"I moved out, so it's over." The affirmative claim survives the tenancy.
"I never told them, but they should have known." Constructive notice is possible for obvious or long-standing conditions, but a tenant who reported nothing usually loses on element three.
"They raised my rent after I complained — that's just business." Within 180 days it is presumed retaliatory under § 1942.5.
Where it came from
The old rule came from agricultural England, where a lease was in substance a conveyance of land and the buildings on it were incidental. Applied to twentieth-century urban apartments, it produced a result nobody would have designed: a tenant who could not repair the building, could not inspect it before signing in any meaningful way, and had no bargaining power, nonetheless bore the whole risk that it would become uninhabitable.
Green (1974) discarded it, holding the modern residential lease is a contract for a package of goods and services and that the covenants in it are mutually dependent. The tenant's rent obligation and the landlord's maintenance obligation rise and fall together.
The Legislature had already been moving in the same direction, and the statutory scheme at §§ 1941 to 1942.5 supplies what Green did not: a definition of untenantability, a self-help remedy with limits, a rent-collection bar, and a retaliation presumption.
The non-waiver provision is the keystone. A warranty that could be disclaimed in the lease would have been worth nothing, because the party drafting the lease is the one the warranty runs against.
Common questions
Can my lease waive the warranty of habitability?
No. Civil Code § 1942.1 makes any agreement waiving the rights under §§ 1941 or 1942 void as against public policy, however it is worded.
I paid rent the whole time. Did I give up my claim?
No. You recover the difference between the rent you paid and the reasonable rental value of the unit in its defective condition, for the period covered by the limitations period.
Can I stop paying rent until it is fixed?
You can withhold, but there is no statutory protection. Withholding is a defense you must prove was justified, and if a court disagrees you can be evicted. Repair and deduct under § 1942 is the safer route within its limits.
How much can I repair and deduct?
Up to one month's rent, after giving notice and a reasonable time to repair — presumed to be 30 days — and no more than twice in any 12-month period.
My landlord raised the rent right after I complained. Is that legal?
There is a presumption of retaliation under Civil Code § 1942.5 if it happens within 180 days of your exercising habitability rights, and the section carries its own damages and attorney's fees.
I already moved out. Is it too late?
No. The affirmative claim survives the tenancy. The deadline depends on the theory — four years on a written lease, but only two years for a personal injury caused by the condition.
