California Security Deposit Laws: The One-Month Cap, 21-Day Return, and Penalties
Deposit Cap · Allowable Deductions · 21-Day Return · Itemized Statement · Interest · Penalties
California security deposit law is set almost entirely by one statute — Civil Code section 1950.5 — and it changed in a big way on July first, 2024. Assembly Bill 12 cut the maximum deposit to a single month’s rent for most landlords, replacing the old two-and-three-month limits that many leases and online guides still repeat. This guide walks the whole California framework end to end: how much you may collect now, what you can and cannot deduct, the twenty-one-day return deadline, the itemized statement and receipt rules, the tenant’s pre-move-out inspection right, where city interest rules apply, and the penalty a court can impose when a landlord keeps a deposit in bad faith.
Whether you own one condo or a small portfolio, the rules below apply the same way, because Civil Code section 1950.5 governs statewide. What varies is the layer some cities add on top — interest on deposits, and in a few places extra notice steps. Where a local rule matters, this guide flags it so you know to check the ordinance for the city where your unit sits. Everything here is general information, not legal advice; confirm the current figures and consult a licensed California attorney before acting on a specific dispute.
Below, a short overview video summarizes the California deposit rules; the sections that follow break down each piece in detail — the new cap and its small-landlord exception, deductions versus normal wear and tear, the return timeline, interest, penalties, the move-out walkthrough, and the small-claims path if a dispute cannot be resolved.

The AB 12 One-Month Cap — the Rule That Changed in 2024
The single most important thing to know is that California’s deposit cap dropped. For decades, Civil Code section 1950.5 let a landlord collect up to two months’ rent for an unfurnished unit and up to three months’ rent for a furnished unit, on top of the first month’s rent. Assembly Bill 12 changed that. For any deposit collected on or after July first, 2024, the maximum security deposit is one month’s rent, and that single limit applies whether the unit is furnished or unfurnished. If your lease template, your management software, or an older guide still says two or three months, it is out of date — and charging the old amount is now a live legal error that can expose you to a refund claim.
The Old “Two Months Unfurnished, Three Months Furnished” Rule Is Gone
Before July first, 2024, California allowed up to two months’ rent (unfurnished) or three months’ rent (furnished) as a deposit. That is the figure many lease forms and web pages still show. It no longer reflects California law. Under Assembly Bill 12, the deposit is capped at one month’s rent for nearly every landlord. Collecting more than the current cap can force a refund and, if a dispute reaches court, undermine your position. Always verify the current cap before you set a deposit amount.
The Small-Landlord Exception
Assembly Bill 12 kept a narrow carve-out for small owners. A landlord may collect up to two months’ rent as a deposit only if both conditions are met: first, the landlord is a natural person, or a limited liability company in which every member is a natural person; and second, that landlord owns no more than two residential rental properties that together contain no more than four dwelling units offered for rent. A landlord who exceeds either threshold — owning through a corporation, or owning a third property or a fifth unit — is back to the one-month cap.
The Service-Member Override
There is an override inside the exception. Even a qualifying small landlord may charge only one month’s rent when the tenant is a service member on active duty. In other words, the two-month small-landlord allowance never applies to a military tenant; that tenant always gets the one-month cap. This mirrors California’s broader protections for service members, and it means you cannot use the small-landlord exception to charge a deploying tenant a larger deposit.
| Situation | Maximum Deposit (on or after July 1, 2024) |
|---|---|
| Most landlords (furnished or unfurnished) | One month’s rent |
| Small landlord: natural person / all-natural-person LLC, no more than two properties and four units | Up to two months’ rent |
| Any landlord, tenant is an active-duty service member | One month’s rent |
| Pre-July 2024 history (no longer current) | Two months (unfurnished) / three months (furnished) |
Takeaway
Since July 2024, the California deposit cap is one month’s rent for most landlords. A qualifying small landlord — a natural person or all-natural-person LLC with no more than two properties and four units — may charge two months, but never to a service member. The old two-and-three-month rule is history. Verify the current cap before setting any deposit.
What a Landlord May Deduct — and What Counts as Wear and Tear
Civil Code section 1950.5 lists the only purposes a California landlord may deduct from a security deposit. The landlord bears the burden of proving each deduction is legitimate, so anything not clearly on the list is presumed to be the landlord’s cost to absorb.
Permitted Deductions
- Unpaid rent. Rent that remains owed for the final month or any earlier period.
- Cleaning to move-in condition. The reasonable cost to return the unit to the same level of cleanliness it had when the tenant moved in — not a blanket “make it spotless” charge.
- Repair of damage beyond ordinary wear and tear. Broken fixtures, large holes, pet-stained flooring, and similar damage the tenant or their guests caused.
- Restoring or replacing personal property. Where the lease specifically allows it, the cost to restore or replace furnishings, keys, or other personal property provided with the unit, other than through normal wear.
Not Deductible — Ordinary Wear and Tear
Ordinary wear and tear is the natural deterioration that happens from living in a unit normally, and the landlord must absorb it. California treats these as non-deductible:
- Faded or lightly scuffed paint, and small nail holes from hanging pictures.
- Carpet worn thin along walkways from ordinary foot traffic, with no stains or pet damage.
- Minor marks, loose grout, or caulk that has aged around tubs and sinks.
- Worn but still-functioning appliances and fixtures that simply reached the end of their useful life.
The Prorating Rule for Paint and Carpet
Even when repainting or carpet replacement is justified by real damage, a landlord generally cannot charge the tenant the full cost of a brand-new surface. Paint and carpet have an expected useful life, so the charge should be prorated for age — a tenant who damaged a carpet that was already several years into its life should pay only for the remaining life, not a whole new carpet. Charging the full amount for an old surface is a common way landlords lose deposit disputes.
Takeaway
You may deduct only for unpaid rent, cleaning to the move-in level, and damage beyond ordinary wear and tear — plus restoring lease-listed personal property. Faded paint, worn carpet, and small nail holes are wear and tear you absorb. Prorate paint and carpet for age; never bill a tenant for a brand-new surface.
The 21-Day Return Deadline and the Itemized Statement
The deadline California landlords miss most often is the twenty-one-day return rule. Under Civil Code section 1950.5, no later than twenty-one calendar days after the tenant moves out, the landlord must deliver two things: any remaining portion of the deposit, and a written itemized statement explaining every deduction. The clock runs from the day the tenant actually surrenders the unit — keys returned, belongings out — not from the date the lease says it ends.
What the Itemized Statement Must Include
The statement must describe each deduction and its amount. When the deductions for repairs or cleaning come to more than one hundred twenty-five dollars, the landlord must attach supporting documentation: copies of invoices or receipts for work done by a third party, or, if the landlord’s own employees did the work, a written description of the work, the time spent, and the reasonable hourly rate charged. A tenant can waive the receipts in writing, but attaching them is always the safer course.
Missing the Deadline Can Forfeit the Whole Deduction
If a landlord fails to send the itemized statement and any refund within twenty-one days, the landlord can lose the right to keep any part of the deposit — even for real, documented damage. The twenty-one-day rule is treated as a hard deadline, not a target. Calendar it the moment the tenant surrenders, and mail the deposit and statement with proof of mailing well before day twenty-one.
No Forwarding Address? The Clock Still Runs
A California tenant is not required to give a forwarding address, and the absence of one does not pause the twenty-one-day clock. If the tenant leaves no address, mail the deposit and itemized statement to the last known address — commonly the rental unit itself — and keep proof of mailing. Do not sit on the funds waiting for an address; the obligation to send the statement on time still applies.
Takeaway
Return the deposit and a written itemized statement within twenty-one calendar days of move-out. Attach receipts whenever repair or cleaning deductions exceed one hundred twenty-five dollars. Miss the deadline and you can forfeit the right to keep anything — even for genuine damage.
The Pre-Move-Out Inspection Right
One of the most useful — and most overlooked — features of California law is the tenant’s right to an initial inspection before moving out. Under Civil Code section 1950.5, a departing tenant may request an inspection roughly two weeks before the end of the tenancy. The landlord must give reasonable written notice of the tenant’s option to be present, and if the tenant requests it, conduct the walkthrough.
At that initial inspection, the landlord gives the tenant an itemized list of the cleaning and repairs that would otherwise be deducted. This gives the tenant a genuine chance to fix the issues before the final move-out. If the tenant remedies the listed items, the landlord cannot then deduct for them. The landlord may still deduct for damage that was concealed at the initial inspection, for issues that arose afterward, or for items the tenant chose not to cure.
Why the Initial Inspection Protects Both Sides
For the tenant, the initial inspection is a chance to earn back more of the deposit by curing problems. For the landlord, offering it correctly reduces disputes, documents the unit’s condition before surrender, and demonstrates good faith — which matters if a deduction is later challenged. Handled well, the pre-move-out walkthrough turns a common flashpoint into a shared checklist. California also publishes guidance through the California pre-move-out inspection notice, which explains the notice a landlord provides.
Interest on Deposits — a Local Question
California has no statewide requirement to pay interest on a security deposit, and no statewide rule that the deposit be held in a separate account. Many California landlords hold deposits in a general account and pay no interest, which is entirely lawful statewide.
The important exception is local. A number of California cities do require landlords to pay annual interest on deposits for covered units. These include San Francisco, Los Angeles, West Hollywood, and Santa Monica, among others such as Berkeley and Oakland. The interest rate is typically set each year by the local rent board, and the rules on which units are covered vary by city. Because these ordinances change and are strictly local, treat interest as a “check your city” item rather than a statewide obligation, and verify the current rate before a return.
Separate Account and Non-Refundable Fees
Two further points often confuse landlords. First, California does not require a separate deposit account statewide, though keeping deposits segregated is a sound practice. Second, and more important, California does not allow non-refundable deposits or fees of any kind. Under Civil Code section 1950.5 every security deposit is refundable, no matter what the lease calls it — a “non-refundable cleaning fee” or “non-refundable pet fee” is treated as part of the refundable deposit and must be accounted for at move-out. A pet deposit is allowed, but it counts toward the overall cap and is refundable like any other deposit.
Takeaway
There is no statewide interest requirement and no separate-account mandate, but cities such as San Francisco, Los Angeles, West Hollywood, and Santa Monica require interest — check the local ordinance. And remember: no California deposit or fee can be non-refundable. Every dollar collected as a deposit is refundable.
Penalties for Bad-Faith Withholding
California backs the deposit rules with real teeth. Under Civil Code section 1950.5, if a court finds that a landlord retained the deposit in bad faith, it may award the tenant statutory damages of up to twice the amount of the security deposit, in addition to any actual damages the tenant proves. That multiplier is on top of returning whatever was wrongfully withheld.
Bad faith is not merely being wrong about a deduction. It generally means the landlord acted unreasonably — ignoring the twenty-one-day deadline, inventing charges, refusing to itemize, or keeping the deposit with no legitimate basis. A landlord who returns the deposit and a clear itemized statement on time, with receipts for larger charges, is well protected even if a specific deduction is later disputed. The penalty exists to punish the landlord who treats the deposit as free money, not the one who makes a good-faith judgment call.
How the “Twice the Deposit” Math Adds Up
Consider a deposit of one month’s rent that the landlord withholds entirely with no itemized statement. The tenant can sue for the wrongfully withheld amount, plus up to twice the deposit in statutory damages for the bad-faith retention. On a typical California rent, that quickly reaches several times the original deposit — far more than any legitimate deduction would have been. The lesson is simple: the cost of doing it right is trivial next to the cost of doing it wrong.
The Move-Out Procedure, Step by Step
Put the rules together and the California move-out becomes a repeatable checklist rather than a judgment call. Follow this sequence and penalty exposure all but disappears.
Offer the initial inspection
Once the tenancy is ending, give written notice of the tenant’s right to a pre-move-out inspection about two weeks out. If requested, walk the unit and hand over an itemized list of proposed deductions the tenant can cure.
Inspect and photograph at surrender
When the tenant returns the keys, inspect promptly and photograph every room. Compare against the signed move-in checklist to separate tenant damage from wear and tear.
Calculate lawful deductions
Deduct only for unpaid rent, cleaning to move-in level, and damage beyond wear and tear. Prorate paint and carpet for age. Gather an invoice or receipt for each charge.
Write the itemized statement
List every deduction with a description and amount. Attach receipts or invoices whenever repair or cleaning deductions exceed one hundred twenty-five dollars.
Return within twenty-one days
Mail or deliver the remaining deposit and the itemized statement within twenty-one calendar days of move-out, using a method that gives you proof of mailing.
A thorough move-out record starts at move-in. Use a documented California move-in and move-out checklist and photographs at both ends so you can prove exactly what the tenant caused. When you do withhold, a clean California security deposit itemization form keeps the statement organized and defensible.
When a Dispute Reaches Small Claims Court
Most deposit disputes never reach a courtroom, but when they do in California, they usually land in small claims court — a forum designed to be used without a lawyer. As of 2026, an individual can sue for up to twelve thousand five hundred dollars in California small claims, which comfortably covers a deposit dispute and the statutory multiplier in most cases. Verify the current limit, which the Legislature adjusts over time.
✓ The Landlord Who Wins
- Signed move-in checklist plus dated move-in photos.
- Written notice offering the pre-move-out inspection.
- Itemized statement mailed within twenty-one days.
- Receipts attached for every charge over the threshold.
- Proof of mailing (certified mail or a tracked method).
✕ The Landlord Who Loses
- No move-in documentation to compare against.
- A vague statement listing “cleaning” or “painting” with no detail.
- Deductions for ordinary wear and tear.
- Full-price charges for old paint or carpet, not prorated.
- A return sent after the twenty-one-day deadline.
The pattern is consistent: California deposit cases are won on paper. The landlord who documents condition at both ends, offers the initial inspection, itemizes clearly, attaches receipts, and mails on time rarely loses — and the tenant who keeps their own photos and a copy of the written statement is equally well positioned to recover a wrongful withholding.
Special Situations: Sale of the Property, Roommates, and Rent Increases
Beyond a routine move-out, a handful of situations trip up California landlords because the deposit rules interact with other events. Three come up often.
When the Property Is Sold
If a landlord sells the rental, Civil Code section 1950.5 requires that the deposit be handled in one of two ways. The seller may either transfer the remaining deposit (after any lawful deductions) to the new owner — the successor in interest — or return the remaining deposit directly to the tenant with a full accounting. If the deposit is transferred, the seller must notify the tenant, by personal delivery or first-class mail, of the transfer, any deductions taken, the amount transferred, and the new owner’s name, address, and phone number. This matters to buyers too: if these steps are skipped, the new owner can be held jointly liable with the seller for repaying the deposit. A landlord buying an occupied California property should confirm in escrow that deposits are transferred and documented.
Roommates and a Single Deposit
Where several tenants share a lease and a single deposit, California treats the deposit as one sum tied to the tenancy, not as separate shares. When one roommate leaves and another stays, the landlord’s twenty-one-day obligation is generally triggered only when the tenancy as a whole ends and the unit is surrendered — not each time one roommate moves out mid-lease. Sorting out each roommate’s share of a refund is usually a private matter among the tenants. Landlords should return the single deposit to the tenants collectively unless the lease or a written agreement directs otherwise, and avoid getting drawn into splitting it.
The Deposit Cap and a Rent Increase
The one-month cap is measured against the rent. If rent later rises, California does not let a landlord automatically demand more deposit to “top up” to the new one-month figure for a deposit that was already lawfully collected. Landlords weighing a rent increase should review the separate rules that govern it — see our guide to California rent increase laws — and should not treat a permitted rent bump as a license to collect a larger deposit from a sitting tenant. Set the deposit correctly at signing and leave it there.
Documentation: the Evidence That Wins Deposit Cases
Every rule above ultimately turns on proof. California places the burden on the landlord to justify each deduction, which means the landlord who cannot document a charge loses it — regardless of whether the damage was real. Build the evidence file across the whole tenancy, not at the end.
At Move-In
- A written condition checklist, room by room, signed and dated by the tenant.
- Timestamped photos or video of every wall, floor, fixture, and appliance, stored where the date cannot be doubted.
- A written note of any pre-existing wear, so it is never later charged to the tenant.
During the Tenancy
- A dated log of every maintenance request and the landlord’s response, which also rebuts a habitability defense.
- Records of any lawful entry to inspect or repair, made with proper notice under California entry rules — see California landlord entry laws.
At Move-Out
- The written initial-inspection list, if the tenant requested the pre-move-out walkthrough.
- A second set of timestamped photos taken at surrender, to compare against move-in.
- Invoices, receipts, or a documented in-house cost for every charge, attached when repair or cleaning deductions top one hundred twenty-five dollars.
- Proof that the itemized statement and refund were mailed within twenty-one days.
The Single Most Common Failure
The deduction California landlords lose most often is the vague one: a line that reads “cleaning” or “painting” with a number and nothing behind it. A tenant can challenge that in small claims and usually win, because the landlord cannot show the work, the cost, or that it went beyond ordinary wear and tear. Specificity is the whole game — “professional carpet cleaning to remove pet odor, invoice attached” survives; “cleaning” does not.
Landlord Best Practices to Avoid Deposit Disputes Entirely
The cheapest deposit dispute is the one that never happens. A few disciplined habits protect a California landlord across an entire portfolio.
- Document move-in exhaustively. A signed checklist and dated photos of every room create the baseline that decides every future deduction.
- Set the deposit at the current cap, and no higher. One month’s rent for most landlords, two only if you genuinely qualify for the small-landlord exception, and one for a service member.
- Call it a deposit, and treat it as refundable. Never label a fee non-refundable; every dollar you collect as a deposit is refundable in California.
- Offer the initial inspection every time. It reduces disputes and demonstrates good faith.
- Calendar the twenty-one-day deadline at surrender and mail the statement with proof, well before it expires.
- Screen carefully before you ever hand over keys. The tenants most likely to leave a unit in disputed condition are often the ones a thorough screening would have flagged.
That last point is where most disputes are actually won — before the lease is ever signed. A prior eviction, a pattern of damage, or unstable finances rarely appears out of nowhere; it usually leaves a trail an applicant’s history reveals. Screening for it is the single highest-leverage habit a California landlord can build.

Frequently Asked Questions
How much can a landlord charge for a security deposit in California?
Since July first, 2024, Assembly Bill 12 caps the security deposit at one month’s rent for both furnished and unfurnished units. A narrow exception lets a small landlord — a natural person, or a limited liability company whose members are all natural persons, who owns no more than two residential rental properties totaling no more than four dwelling units — collect up to two months’ rent. Even that small landlord is limited to one month’s rent when the tenant is a service member. The older two-months-unfurnished and three-months-furnished limits no longer apply. Verify the current law, as figures change.
How long does a California landlord have to return a security deposit?
No later than twenty-one calendar days after the tenant moves out, the landlord must return the deposit along with an itemized written statement of any deductions, under Civil Code section 1950.5. The clock runs from surrender of the unit, not from the lease end date. Missing the twenty-one-day deadline can forfeit the right to keep any part of the deposit.
Can a landlord charge a non-refundable deposit or cleaning fee in California?
No. Under Civil Code section 1950.5, every security deposit in California is refundable, regardless of what it is called. A landlord cannot label money non-refundable to avoid the return rules — any cleaning fee, pet fee, or similar charge collected as a deposit is treated as part of the refundable security deposit and must be accounted for at move-out.
What can a California landlord deduct from a security deposit?
A landlord may deduct only for unpaid rent, cleaning needed to return the unit to its move-in level of cleanliness, repair of damage beyond ordinary wear and tear, and — if the lease allows — the cost to restore or replace personal property such as furniture or keys. A landlord may not charge for ordinary wear and tear, such as faded paint, worn carpet, or minor nail holes.
Does a California landlord have to provide receipts for deductions?
Yes, when deductions for repairs or cleaning total more than one hundred twenty-five dollars, the itemized statement must include copies of the invoices, receipts, or, if the landlord’s own staff did the work, a description of the work with the time spent and the reasonable hourly rate. A tenant may waive the receipts in writing, but the safer practice is always to attach them.
What is a pre-move-out inspection in California?
Under Civil Code section 1950.5, a departing tenant has the right to request an initial inspection roughly two weeks before moving out. The landlord must give the tenant a written itemized list of the cleaning and repairs that would be deducted, so the tenant has a chance to fix them before move-out and avoid the deductions. The landlord cannot then deduct for anything the tenant remedied or for new issues arising after the initial inspection.
Does a California landlord have to pay interest on a security deposit?
There is no statewide requirement to pay interest on a security deposit in California. However, several cities — including San Francisco, Los Angeles, West Hollywood, Santa Monica, Berkeley, and others — require landlords to pay annual interest on deposits for covered units. Rates are set locally and change, so check the current ordinance for the city where the unit sits.
What is the penalty if a California landlord wrongfully keeps a deposit?
If a court finds the landlord retained the deposit in bad faith, Civil Code section 1950.5 lets it award the tenant statutory damages of up to twice the amount of the security deposit, on top of any actual damages the tenant proves. That is a powerful incentive to return the deposit and the itemized statement on time and to document every deduction.
Does a California tenant have to give a forwarding address to get the deposit back?
A tenant is not required to give a forwarding address, and the twenty-one-day deadline still runs. If the tenant leaves no forwarding address, the landlord should mail the deposit and itemized statement to the last known address, which is usually the rental unit itself, and keep proof of mailing. Providing a forwarding address simply makes the return smoother.
Can a California tenant use the security deposit as last month’s rent?
Not unless the lease specifically designates part of the deposit as last month’s rent. A security deposit is meant to cover unpaid rent and damage after move-out, so a tenant who simply stops paying and says to use the deposit is treated as in default and can face a pay-or-quit notice. At move-out, the landlord may apply the deposit to any unpaid rent. For the demand process, see our guide on dealing with a non-paying tenant.
