Security Deposit Rules Every California Landlord Must Know
Published by Nicholas Darracq | North County Premier Property Management | 2026
Security deposit disputes are one of the fastest ways to end up in small claims court — and one of the easiest things to get wrong as a California landlord.
Between AB 12’s new deposit limits, AB 2801’s photo documentation requirements, and AB 414’s electronic return rules, the landscape has changed significantly in the past two years.
Here’s a complete breakdown of what California law requires, what you can and can’t deduct, and how to protect yourself.
How Much Can You Charge?
The New Standard: One Month’s Rent
As of July 1, 2024, Assembly Bill 12 (AB 12) limits the maximum security deposit for any residential rental to one month’s rent.
This applies regardless of whether the unit is furnished or unfurnished. Before AB 12, landlords could charge up to two months’ rent for unfurnished units and three months’ rent for furnished units. That distinction no longer exists.
This one-month cap includes everything — the security deposit, any pet deposit, key deposit, cleaning deposit, or any other refundable charge by any name.
You cannot collect a “security deposit” of one month plus a separate “pet deposit” on top of it. It all counts toward the one-month limit.
The Small Landlord Exception
There is one exception.
If you are a natural person (or an LLC where all members are natural persons, or a family trust), and you own no more than two residential rental properties containing a total of four or fewer dwelling units offered for rent, you may charge up to two months’ rent as a security deposit.
This exception is relevant for many Carlsbad landlords who own one or two single-family rentals. If you personally own two rental homes and nothing else, you qualify.
However, there is a hard limit on this exception: if the prospective tenant is an active-duty military service member, the small landlord exception does not apply.
The maximum deposit for a service member is one month’s rent, period, regardless of how many properties you own.
Existing Deposits Are Grandfathered
AB 12 applies only to deposits collected on or after July 1, 2024.
If you collected a lawful two-month deposit under the old rules before that date, you are not required to refund the difference. The higher deposit remains in effect until the tenancy ends.
What Can You Deduct?
California Civil Code Section 1950.5 allows landlords to deduct from a security deposit for four specific reasons — and only these four:
1. Unpaid Rent
If the tenant owes rent at move-out, you may deduct the amount owed from the deposit.
2. Cleaning
You may deduct the cost of cleaning the unit to return it to the same level of cleanliness it was in at the beginning of the tenancy, exclusive of ordinary wear and tear.
As of January 1, 2025, you cannot charge for professional carpet cleaning unless it is reasonably necessary to address conditions beyond normal wear and tear.
Routine carpet cleaning at turnover, without documented damage or excessive soiling, is no longer a valid deduction.
3. Repair of Damage Beyond Normal Wear and Tear
You may deduct for repairs to damage caused by the tenant, their guests, or their pets that goes beyond what would naturally occur from ordinary use of the unit.
You cannot deduct for conditions that result from normal aging or use.
4. Restoration of Personal Property
If the lease permits it, you may deduct for the cost of restoring or replacing personal property (such as furnishings) that was damaged by the tenant beyond normal wear and tear.
Normal Wear and Tear: What You Cannot Deduct For
This is where most disputes happen.
California law defines normal wear and tear as deterioration that results from the intended use of a dwelling, including breakage or malfunction due to age or deterioration.
Not Deductible (Normal Wear and Tear)
- Carpet worn thin from normal foot traffic
- Small nail holes in walls from hanging pictures
- Faded or slightly discolored paint from sunlight exposure
- Minor scuffs on walls or baseboards
- Worn finish on hardwood floors in high-traffic areas
- Loose door handles or cabinet hardware from regular use
- Faded window coverings
- Minor wear to countertops from daily use
Deductible (Tenant Damage Beyond Normal Wear and Tear)
- Cigarette burns in carpet or countertops
- Large holes in walls
- Pet urine stains or odor in carpet or subfloor
- Broken windows or mirrors (not from settling or age)
- Excessive grease buildup in kitchen requiring professional cleaning
- Unauthorized paint colors that require repainting
- Broken blinds from misuse
- Mold caused by tenant negligence (blocking ventilation, etc.)
- Flea infestation left by tenant’s pets
Depreciation Matters
You cannot charge a tenant the full replacement cost of an item that has naturally depreciated.
For example, if carpeting has an expected useful life of 10 years and the tenant damaged it in year 7, you can only deduct approximately 30% of the replacement cost — the remaining useful life the tenant’s damage eliminated.
The same principle applies to paint, appliances, and other items with a finite lifespan.
Courts regularly reject deductions where landlords charge full replacement cost for items that were already partially depreciated.
The 21-Day Rule: Returning the Deposit
Within 21 calendar days after the tenant moves out and returns the keys, you must do one of two things:
- Return the full security deposit, or
- Provide a written itemized statement explaining every deduction, along with the remaining balance
This is 21 calendar days — not business days. Weekends and holidays count.
Missing this deadline is one of the strongest pieces of evidence a tenant can use against you in court, and it can result in forfeiture of your right to keep any portion of the deposit.
What the Itemized Statement Must Include
The statement must list each specific deduction, the dollar amount, and the reason.
For any repair or cleaning that costs more than $125, you must include copies of receipts or invoices.
If the work has not yet been completed within the 21-day window, you may provide a good-faith estimate of the cost — but you must then send the actual receipts within 14 days after the work is done, along with any additional refund owed if the actual cost was less than the estimate.
Photo Documentation Is Now Required (AB 2801)
Assembly Bill 2801, which took full effect on July 1, 2025, added significant documentation requirements to the deposit return process.
Move-In Photos
For any tenancy beginning on or after July 1, 2025, the landlord must photograph the unit before the tenant moves in and provide those date-stamped photos to the tenant.
Move-Out Photos
For all tenancies (regardless of start date), the landlord must photograph the unit after the tenant moves out and before any cleaning or repairs are performed.
Post-Repair/Cleaning Photos
If you make a deduction for repairs or cleaning, you must also photograph the unit after the work is completed.
All Three Sets of Photos Must Be Included
Move-in, move-out, and post-repair photos must all be included with the itemized statement within the 21-day window.
Photos can be delivered by mail, email, flash drive, or by providing a link where the tenant can view them online.
If you fail to provide the required photos, you may forfeit your right to retain any portion of the deposit for the items that were not documented.
Anything not captured in move-out photos cannot be deducted later, unless the tenant’s personal belongings obscured the condition at the time of the walkthrough.
Electronic Returns (AB 414 — Effective January 1, 2026)
If the tenant paid rent or the deposit electronically during the tenancy, you must return the remaining deposit electronically using the same method — unless both parties have agreed in writing to a different return method.
For leases with multiple tenants, the deposit must be returned as a single payment payable to all adult tenants on the lease.
If the tenants want it split or directed to one person, all adult tenants must agree in writing.
The Pre-Move-Out Inspection
California law gives tenants the right to request a pre-move-out inspection, and landlords are required to inform tenants of this right in writing after receiving notice of move-out.
How It Works
The inspection must occur no earlier than two weeks before the end of the tenancy and requires 48 hours’ written notice to the tenant of the scheduled date and time.
During the inspection, the landlord identifies any conditions that could result in deposit deductions and provides the tenant with an itemized list at the time of the inspection.
Why It Matters
The purpose is to give the tenant an opportunity to address identified issues before the final move-out — patching nail holes, cleaning the oven, addressing carpet stains — so they can avoid deductions.
This benefits both parties: the tenant gets more of their deposit back, and the landlord gets a unit that requires less turnover work.
If you identify damage during the pre-move-out inspection and document it, but the tenant does not remedy it before the final move-out, you have a stronger position for retaining that portion of the deposit.
Conversely, if you fail to offer the inspection, a court may view your deductions less favorably.
Bad Faith Penalties
If a tenant believes you wrongfully withheld their deposit and takes you to small claims court, the consequences can be significant.
Statutory Damages
If the court finds that you retained the deposit in bad faith, it may award the tenant up to twice the amount of the security deposit as a penalty — on top of the actual deposit amount owed.
For a $3,000 deposit, that means potential liability of up to $9,000 ($3,000 owed plus $6,000 penalty).
What Constitutes Bad Faith
Bad faith goes beyond honest mistakes or good-faith disagreements about what constitutes normal wear and tear.
Courts look for patterns such as:
- Failing to return the deposit or provide an itemized statement within 21 days
- Making deductions without receipts or documentation
- Charging for pre-existing conditions or normal wear and tear
- Refusing to respond to the tenant’s inquiries
- Providing fabricated or inflated invoices
The Burden Shifts to You
If a tenant alleges bad faith, the burden of proof shifts to the landlord to demonstrate that the deductions were reasonable.
This is why documentation is everything — move-in photos, move-out photos, receipts, written communications, and a clear itemized statement are your best defense.
