Whether you manage one property or a growing portfolio, understanding California’s current laws on security deposits is essential to protecting your investment, avoiding disputes, and maintaining positive tenant relationships.
Key Takeaways
California limits most residential security deposits to one month’s rent for furnished or unfurnished units starting July 1, 2024, under AB 12.
Deposits must be returned within 21 days of move-out, along with an itemized statement and receipts for any deductions.
Acceptable deductions include unpaid rent, damage beyond normal wear and tear, and cleaning costs to restore the unit to its original condition.
AB 2801 and AB 414 bring new rules about transparency and electronic refunds that landlords should prepare for now.
Partnering with Advantage Property Management Services helps ensure full compliance, proper documentation, and reduced liability risk.
How Much Can California Landlords Collect?
The rules for how much a landlord can collect changed significantly with Assembly Bill 12 (AB 12), signed into law in 2023. This reform reduced the maximum allowable security deposit for most rentals in California to one month’s rent, whether the property is furnished or unfurnished, effective July 1, 2024.
Previously, landlords could collect up to two months’ rent for unfurnished units and three months for furnished ones. Under the new rule, only certain small landlords (those who own no more than two properties totaling four or fewer units) can continue collecting up to two months’ rent from tenants.

Rules for Holding a Security Deposit
California doesn’t require landlords to keep security deposits in separate trust accounts, but doing so is a best practice that builds credibility and simplifies recordkeeping. Many professional management companies, including Advantage Property Management Services, use dedicated accounts to ensure transparency and compliance.
Landlords should also provide tenants with a written lease clause outlining:
The amount collected and date received
The conditions under which deductions may be made
A statement confirming the deposit is refundable
Proper documentation helps avoid disputes and protects the landlord in case of a legal challenge.
When Can You Legally Deduct from the Deposit?
California law allows landlords to make deductions only for specific reasons. Acceptable deductions include:
Unpaid Rent or Late Fees
Any outstanding rent balance can be deducted from the deposit.Damage Beyond Normal Wear and Tear
Normal wear includes faded paint or worn carpets. Damage such as holes in walls, broken fixtures, or missing appliances qualifies for a deduction.Cleaning Costs
You can charge for cleaning required to return the unit to the same level of cleanliness it had at move-in, excluding ordinary use.Repair or Replacement Costs
If repairs are needed due to tenant negligence, landlords can deduct reasonable expenses.
Always keep invoices, receipts, or estimates to justify each deduction. AB 2801 emphasizes documentation and transparency, strengthening the tenant’s right to an accurate accounting of how their deposit was used.
The 21-Day Return Rule
Under California Civil Code §1950.5(g), landlords must return the tenant’s deposit within 21 calendar days after move-out. This return must include:
The remaining balance of the deposit
An itemized statement detailing any deductions
Copies of invoices or receipts for work completed
If work cannot be completed within that period, the landlord may provide a good-faith estimate of the charges, followed by actual receipts within 14 days of completion.
Failure to meet these requirements can result in the landlord owing up to twice the amount of the deposit in damages, plus potential legal fees.
Electronic Refunds and AB 414
Starting January 1, 2026, landlords in California will have the option, and sometimes the obligation, to issue electronic refunds for security deposits under Assembly Bill 414 (AB 414).
This bill modernizes the process, allowing funds to be returned via electronic transfer when both parties agree. It aims to reduce mailing delays, minimize lost checks, and increase accountability in the return process.
Advantage Property Management Services has already begun integrating electronic return systems to ensure seamless compliance well before the 2026 deadline.
Common Mistakes Landlords Should Avoid
Even experienced landlords can run into trouble with California’s complex security deposit laws. Here are some common missteps to avoid:
Collecting more than the legal limit under AB 12.
Failing to return the deposit on time or omitting required receipts.
Charging for normal wear and tear instead of legitimate damage.
Withholding deposits for unverified repairs or without proper documentation.
Using security deposits as last month’s rent, which is not permitted unless clearly stated and agreed upon in writing.
Professional management helps reduce these risks through consistent documentation, legal awareness, and standardized move-in and move-out procedures.

FAQs About California Security Deposits
1. Can I collect a pet deposit in addition to the regular security deposit?
No. The total combined amount, including pet deposits, cannot exceed the one-month rent limit set by AB 12 unless you qualify as a small landlord exemption.
2. What happens if a tenant breaks the lease early?
You may use the security deposit to cover unpaid rent during the time it takes to re-rent the property, but you must make reasonable efforts to find a new tenant promptly.
3. Do I have to provide photos of damages?
Photos are not required by law, but they are highly recommended as supporting evidence if a dispute arises.
4. Can tenants request a pre-move-out inspection?
Yes. Tenants have the right to request an inspection within two weeks of moving out so they can fix issues before deductions occur.
5. What if the tenant leaves no forwarding address?
Send the deposit statement and refund to the tenant’s last known address. You’ll have fulfilled your legal obligation even if the mail is returned.
