California Lease Agreement: 10 Clauses Every Landlord Must Include

When a California lease is defective, it is usually not because the landlord did something aggressive. It is defective because the document was assembled from a template written for another state, or written for California three legislative sessions ago, and nobody has read it line by line since. The result is a contract that looks complete, gets signed by both parties, and then fails in the exact moment it was supposed to protect you: at move-out, at a rent increase, or in front of a small-claims judge.

This guide walks through the ten clauses that carry the most weight in a California residential lease, what each one has to say to survive contact with the Civil Code, and where landlords most often get them wrong.

Why California Is Different

California has some of the most tenant-friendly laws in the nation. As a landlord, your lease must comply with the California Civil Code, local rent control ordinances, and recently enacted legislation like AB 1482 (the Tenant Protection Act). Missing a required disclosure or clause doesn't just create risk — it can void parts of your agreement entirely.

Two features of California law make this harder than it looks. The first is layering. State statute sets a floor, but a local ordinance in Los Angeles, San Francisco, Oakland, or Santa Monica can impose stricter rent, eviction, and deposit rules on top of it, and the stricter rule generally governs. The second is pace. The deposit cap moved in 2024. Documentation standards for deductions moved again in 2025. A lease that was fully compliant the day you wrote it can drift out of compliance without a single word of it being edited.

And when a clause fails in California, it usually fails quietly. Nothing bounces it back to you. It simply stops being something a court will enforce, and you find out at the worst possible moment.

1. Security Deposit Terms (Civil Code §1950.5)

California previously capped security deposits at 2 months' rent for unfurnished units and 3 months' for furnished. As of July 2024, AB 12 reduced this to just 1 month's rent for most landlords, and this remains the current limit. Your lease must clearly state the deposit amount, the conditions for deductions, and the 21-day return timeline.

Labeling matters less than most landlords hope. Section 1950.5 defines security by what the money is there to do, not by what the lease calls it, so key deposits and similar refundable up-front charges count toward the same cap and renaming a charge is rarely a way around the ceiling. The narrow exception that lets qualifying small landlords collect up to two months' rent is narrower than it sounds, and it is worth confirming you actually qualify before you draft to it.

The return side is where the money is actually lost. Under Cal. Civ. Code § 1950.5 the clock is 21 calendar days after the tenant has vacated the premises, not from the lease end date and not from whenever you get around to inspecting. Inside that window you owe the balance and an itemized statement, and once repair and cleaning deductions together exceed $125 — an aggregate floor, not a per-item one — the statement has to carry backup: a description of the work plus the time spent and hourly rate if you or your employee did it, a copy of the bill, invoice or receipt if someone else did it or supplied materials, and either way the photographs subdivision (g) has required since 2025, with a written explanation of the cost. Miss that window and the deposit stops being yours to hold: under Granberry v. Islay Investments (1995) 9 Cal.4th 738, a landlord who does not comply with the statute loses the right to keep any of the security on the strength of the landlord's own accounting, and whatever the landlord still believes is owed has to be pursued as a claim the landlord proves, with the burden of proof on the landlord (§1950.5(m)). Bad faith costs more. Under §1950.5(h)(7) a landlord who in bad faith fails to comply with those requirements is not entitled to claim any amount of the security, and §1950.5(m) exposes a bad-faith claim or retention to statutory damages of up to twice the deposit on top of actual damages, in a small-claims forum that hears a natural person's claim up to $12,500. There is no statewide requirement to pay interest on a deposit, but some cities — San Francisco and Berkeley among them — do, so this clause should follow your city rather than the state.

2. Rent Increase Notice Requirements

Under AB 1482, annual rent increases are capped at 5% + local CPI (max 10%) for properties 15+ years old. You must provide 30 days notice for increases under 10% and 90 days for 10% or more. Include specific language about how and when rent may be adjusted.

The cap is not universal, and the exemptions are where leases go wrong. Newer construction falls outside AB 1482 on a rolling basis, and single-family homes and condominiums owned by individuals rather than corporate entities can be exempt as well — but only if the tenant has been given the statutory exemption notice. Leave it out and you lose the exemption for as long as it is missing. That is a drafting failure, not a legal one, and it is fixable going forward: §1947.12 lets the notice stand as a separate writing for a tenancy predating July 1, 2020, but requires it in the rental agreement for any tenancy commenced or renewed since. If you are relying on an exemption, the language establishing it belongs in the signed lease, not in your files.

3. Lead-Based Paint Disclosure

For any property built before 1978, federal law requires a lead-based paint disclosure. Failure to provide this can result in penalties up to $19,507 per violation. Include the EPA pamphlet and disclosure form as lease addenda.

This requirement is unusual in that it is federal, it applies in every state, and it is entirely mechanical. The lease needs the Lead Warning Statement, disclosure of any known hazards or records, the tenant's signed acknowledgment, and delivery of the EPA pamphlet before signing. There is no substantial-compliance argument worth leaning on: either the signed addendum exists in your file or it does not. For a pre-1978 building this is among the cheapest items on the compliance list, and a common omission.

4. Entry Notice Requirements (Civil Code §1954)

Landlords must provide 24 hours written notice before entering a rental unit, except in emergencies. Your lease should specify the notice method and permitted reasons for entry.

The notice has to be more than a courtesy heads-up. It should state the date, the approximate time, and the purpose of the entry, and the entry itself must fall within normal business hours unless the tenant agrees otherwise. A clause allowing the landlord to enter "at any reasonable time" or "to show the unit as needed" reads fine on paper and then becomes the exhibit in a harassment claim once a pattern of entries builds up. Draft the clause to your statutory obligation, and then actually paper each entry.

5. Maintenance Responsibilities

California's implied warranty of habitability requires landlords to maintain livable conditions. Your lease should clearly delineate maintenance responsibilities between landlord and tenant, including who handles minor repairs, pest control, and appliance maintenance.

Splitting responsibilities is legitimate. A lease can reasonably put light-bulb replacement, drain clogs caused by the tenant, and routine filter changes on the resident. What a lease cannot do is move the core obligation. The implied warranty of habitability covers weatherproofing, plumbing, heat, electrical service, sanitary facilities, and structural integrity, and it stays with the landlord no matter what the parties signed.

This is why an "as is" clause fails outright. Section 1942.1 makes any agreement waiving or modifying the tenant's rights under §1941 or §1942 void as contrary to public policy with respect to any condition that renders the premises untenantable — not merely unwise, not merely unlikely to survive a challenge, but treated as though those words had never been written into the agreement. The statute leaves one opening, and it is the one described above: the parties may agree that the tenant will improve, repair or maintain "all or stipulated portions of the dwelling as part of the consideration for rental." Read with the rest of the sentence, that opening covers work the tenant takes on as part of the bargain, not a condition that renders the premises untenantable — that stays outside anything the lease can shift. Light bulbs and filters fit inside it. A clause handing the tenant the habitability obligation wholesale does not. The provisions that tend to travel alongside fare no better: §1953 voids a lease term by which the tenant waives the deposit rights of §1950.5, the entry rights of §1954, or the right to assert a cause of action that may arise in the future, and §1717 turns a one-sided attorney-fee clause into a reciprocal one. Void, though, does not mean gone. The clause stays in the signed document, but nothing has to happen for it to be unenforceable: the tenant does not have to object in writing, or object at all, and can raise the defect for the first time as a defense in court. The months you spent administering the lease as written were never a safe harbor. On your side of the table the repair is cheap: strike the provision at renewal, or paper an addendum that supersedes it, instead of waiting to be told which sentence in your own lease a court was never going to back.

6. Late Fee Policy

California law requires that late fees be "reasonable" — typically no more than 5–6% of the monthly rent. Your lease must specify the grace period, the fee amount, and how it's calculated.

"Reasonable" in California means the fee should approximate the landlord's actual cost of handling a late payment, not punish the tenant for being late. A fee that operates as a penalty is unenforceable, and the downside is worse than losing the fee itself: a tenant who successfully challenges it can turn a straightforward non-payment matter into a contested case. Keep the grace period, the flat amount, and the trigger date explicit, and avoid daily compounding charges that grow without a ceiling.

7. Pet Policy and Pet Deposits

If you allow pets, your lease should detail any pet deposit (included in the overall deposit cap under AB 12), breed or size restrictions, and tenant responsibilities for pet damage.

Two things routinely go wrong in this clause. The first is the deposit arithmetic described above — a pet deposit sits inside the cap, not on top of it. The second is assistance animals. A service animal or a documented emotional-support animal is not a pet, is not subject to your breed or size restrictions, and cannot carry a pet deposit or pet rent. The cleanest drafting keeps the pet policy in one place and separately acknowledges that reasonable-accommodation requests are handled outside of it.

8. Subletting and Assignment Clause

California tenants generally have the right to sublet unless the lease explicitly prohibits it. Include clear language about subletting requirements and your approval process.

Because silence favors the tenant here, the clause has to be affirmative. If you want approval rights, state that assignment and subletting require written consent, describe what an application must contain, and commit to a response window. A flat prohibition with no process attached leaves you nothing to administer when the request actually arrives, and in cities with short-term rental or added-occupant ordinances the local rule may control regardless of what your lease says. A clause that gives you a documented approval process is worth considerably more than one that simply says no.

9. Mold and Bed Bug Disclosures

California Civil Code §1942.5 and local ordinances may require disclosures about mold and pest history. Include appropriate addenda covering these disclosures.

Treat these as delivery obligations rather than as paragraphs. California requires written notice to tenants about bed bugs, including general information and instructions for reporting an infestation, and requires disclosure of known mold conditions affecting habitability. Both are easier to satisfy as signed addenda than as sentences buried in the body of the lease, because what you will need later is proof of delivery on a specific date. The same logic applies to the other disclosures a California lease commonly carries, including registered-sex-offender notice, demolition notice where applicable, and the arrangement for any utility meter that serves more than one unit.

10. Termination and Renewal Terms

Specify how the lease terminates, what happens at the end of the term (auto-renewal vs. month-to-month conversion), and the notice requirements for non-renewal under AB 1482's just-cause eviction protections.

Under the just-cause rules, a covered tenancy does not simply end because the term ran out. Non-renewal has to rest on an enumerated at-fault or no-fault ground, and the no-fault grounds carry relocation-assistance obligations. A lease promising that the tenancy "terminates automatically at the end of the term with no further notice" overstates your position in a covered unit, and that is precisely the sentence a tenant's attorney will read back to you.

Where Non-Compliant Clauses Actually Come From

Many of the failures above were never drafting decisions at all. They were inherited. A landlord buys a building and inherits the prior owner's lease. A property manager carries one template across a portfolio spanning two states. A document is edited once, years ago, and renewed a dozen times since without anyone reading past the rent figure. The clauses that cause trouble are often the ones nobody chose; they were already in the file when it arrived.

That makes the useful exercise a comparison rather than a rewrite. What does this document actually say, and what do the current Civil Code and the local ordinance where the property sits require it to say? The gaps sort into three kinds: provisions that are missing entirely, provisions that are present but now understate what the law demands, and provisions that are affirmatively unenforceable and should be struck before the next signature rather than litigated afterward. The third category is the easiest one to leave alone, on the reasoning that a clause a court will ignore is harmless. It is not harmless. It signals to a tenant's counsel that the rest of the lease was not reviewed either.

Work from the expensive end backward. Deposit terms first, because that is where the statutory damages multiplier lives. Then rent increases and just-cause language, because those errors compound across the life of a tenancy. Then the disclosures, which are cheap to fix and absolute in effect. Then the everyday operational clauses — entry, maintenance, pets, subletting — which matter less in court and more in the day-to-day. Whatever you change, change it before the next renewal, and record the date you reviewed the document, so that next year you are auditing a known baseline instead of starting from zero.
