Quick Answer: California security deposit rules now cap deposits at one month’s rent for most rentals. Landlords must return deposits within 21 days of move out. As of 2026, move in and move out photos are also required. Both landlords and tenants benefit from understanding these rules before signing or renewing a lease.
Indeed, security deposits are one of the most misunderstood parts of renting in California. Whether you own a rental home or you’re moving into one, California security deposit rules affect how much money changes hands and what happens to it. Furthermore, California has updated these rules significantly in recent years. However, many landlords and tenants still operate under old assumptions. As a result, getting this wrong can be costly for both sides.
1. The New Deposit Limit Under California Security Deposit Rules
The biggest change to California security deposit rules came from Assembly Bill 12. It took effect July 1, 2024. Under AB 12, most residential landlords can only charge a security deposit equal to one month’s rent. Specifically, this applies whether the unit is furnished or unfurnished.
Before this law, landlords could charge up to two months’ rent for unfurnished units and three months’ rent for furnished ones. Therefore, those older limits no longer apply to most new leases.
The Small Landlord Exception
There is one important exception. If you own no more than two properties with a total of four or fewer rental units, you may still charge up to two months’ rent as a security deposit. Additionally, this exception is designed for smaller, independent landlords. According to California Civil Code Section 1950.5, these rules apply specifically to residential tenancies.
What This Means in Practice
For tenants, the new cap significantly lowers upfront move-in costs. For example, a tenant renting a $3,000/month home previously could have been asked for a $6,000 deposit plus first month’s rent. Instead, that same tenant now pays $3,000 for the deposit. For landlords, however, this means updating lease agreements to reflect the current legal limits.
2. The 21 Day Return Deadline
Once a tenant moves out, California security deposit rules give landlords exactly 21 calendar days to return the deposit. Alternatively, landlords must provide a written, itemized statement of any deductions within that same window.
This deadline starts the moment the tenant vacates and returns the keys. Missing this deadline is one of the most common mistakes landlords make. Moreover, it is also one of the most avoidable.
What Deductions Are Allowed?
Landlords may deduct for unpaid rent and cleaning costs if the unit was left dirtier than at move in. They may also deduct for repairs covering damage beyond normal wear and tear. However, landlords cannot charge for ordinary wear and tear. For instance, minor scuffs on walls, carpet wear from regular use, and small nail holes are not deductible.
In our experience managing properties across Ventura and Santa Barbara Counties, disputes over wear and tear are among the most frequent issues between landlords and tenants. Furthermore, clear documentation at move-in and move-out makes all the difference in resolving these disputes quickly.
Starting January 1, 2026: Electronic Refund Requirement
Under AB 414, if a tenant paid their deposit electronically, landlords must also return it electronically. This applies unless both parties agree in writing to a different method. Still, this is a new procedural requirement that many landlords are not yet aware of.
3. The New Photo Documentation Requirements
AB 2801 introduced one of the most significant procedural changes to California security deposit rules in recent memory. For tenancies that began on or after July 1, 2025, landlords must now photograph the rental unit before a new tenant moves in. Additionally, they must photograph it again after the tenant moves out and once more after any repairs are completed.
Why This Matters
Moreover, landlords must share these photos with the tenant in writing. Failure to follow this process can eliminate the landlord’s right to make any deductions from the deposit, even if real damage occurred. Consequently, this rule protects tenants from unfair charges. Equally, it protects landlords who document everything correctly.
For landlords managing properties on their own, this adds a new layer of responsibility. Specifically, it requires a consistent, documented system for every tenancy. Many property owners find that working with a professional management team helps ensure compliance with evolving requirements like these.

4. The Pre Move Out Inspection Right
California law gives tenants the right to request a pre-move-out inspection before they leave. This allows both parties to walk through the property together. During this walkthrough, the landlord identifies issues the tenant can fix before vacating, potentially saving them from deposit deductions.
Despite this right existing in state law, many tenants still do not know about it. Similarly, many landlords do not proactively offer it.
Why This Benefits Both Sides
For tenants, requesting this inspection provides the chance to address minor issues before they become deductions. For landlords, conducting the inspection creates a clear paper trail. As a result, it reduces the likelihood of disputes after move-out. The California Department of Consumer Affairs offers guidance on this process that both landlords and tenants should review.
5. What Happens If a Landlord Violates These Rules?
California security deposit rules carry real consequences for non-compliance. If a landlord fails to return the deposit within 21 days, misses the itemized statement deadline, or makes bad faith deductions, a tenant can sue in small claims court. In those cases, the tenant may recover up to twice the wrongfully withheld amount, plus the deposit itself.
Indeed, California courts take these cases seriously. Judges consistently rule in favor of tenants when landlords cannot produce documentation, miss deadlines, or charge for normal wear and tear. Because of this, compliance is not just a legal formality. Also, it is a financial risk management issue.
Understanding and following California security deposit rules from day one protects your investment and avoids preventable legal disputes. Nevertheless, keeping track of every new law, deadline, and documentation requirement is a full time job on its own.
Frequently Asked Questions About California Security Deposit Rules
What are the current California security deposit rules for 2026?
California security deposit rules in 2026 cap deposits at one month’s rent for most residential rentals under AB 12. Small landlords with no more than two properties and four total units may charge up to two months’ rent. Landlords must return deposits within 21 days of move-out. For tenancies starting after July 1, 2025, photo documentation is also required at move in, move out, and after repairs.
How long does a landlord have to return a security deposit in California?
A landlord must return the security deposit, or provide a written itemized statement of deductions, within 21 calendar days after the tenant vacates and returns the keys.
Can a landlord charge first, last, and security deposit in California?
No. Under AB 12, collecting first month’s rent plus a two-month security deposit would exceed the one-month cap for most landlords. Landlords can collect first month’s rent and a security deposit of up to one month’s rent, for a total of two months upfront in most cases.
What can a landlord deduct from a security deposit in California?
Landlords may deduct for unpaid rent, cleaning costs if the unit was left dirtier than at move-in, and repairs for damage beyond normal wear and tear. Deductions for ordinary wear and tear, such as minor wall scuffs or routine carpet wear, are not permitted.
What Happens If a Landlord Returns the Deposit Late?
If a landlord misses the 21 day deadline, California courts treat the failure seriously. Specifically, the tenant may pursue the landlord in small claims court for the full deposit plus a penalty of up to twice the withheld amount. Therefore, timeliness is not optional.
What is the new photo rule for California security deposits?
Under AB 2801, for tenancies beginning on or after July 1, 2025, landlords must photograph the rental unit before move in, after move-out, and after completing any repairs. These photos must be shared with the tenant in writing. Landlords who skip this step risk losing the right to make security deposit deductions.
