California's New Security Deposit Rules for 2026: One Month, 21 Days, and the Photos That Protect Your Deductions
California tightened its security-deposit rules for 2026. Most landlords may collect no more than one month's rent as a deposit, with a limited small-owner exception allowing up to two months. The deposit, minus lawful deductions, must be returned within 21 days with an itemized statement. And for deposits taken on or after January 1, 2026, you generally must photograph the unit before and after any cleaning or repairs, or you can lose the right to deduct. Returns and statements can now be handled electronically by agreement.
Security deposits are one of the most common sources of landlord-tenant disputes, and California added several rules for 2026 that raise the stakes for owners who handle deposits casually. Here is what changed, and what it takes to keep a deduction defensible.
The one-month cap
For tenancies beginning on or after July 1, 2024, the maximum security a landlord may generally demand is one month's rent, whether the unit is furnished or unfurnished. A limited exception allows some small owners to collect up to two months: broadly, a natural person (or an LLC whose members are all natural persons) who owns no more than two residential properties totaling no more than four units, subject to statutory conditions. Refundable pet deposits count toward the cap, and local ordinances can be stricter.
The 21-day return and itemized statement
The core rule is unchanged: within 21 days after the tenant moves out, you must return the deposit balance along with an itemized statement of any deductions. Missing that deadline, or failing to itemize, is one of the most common ways owners lose a deposit dispute. We cover the 21-day deadline and its penalties in more detail separately.
The photo requirement
For deposits taken on or after January 1, 2026, owners generally must document the unit's condition with photographs, before performing any cleaning or repairs after regaining possession, and again afterward, and make those images available to the tenant with the itemized statement. This matters because skipping the required documentation can forfeit your right to deduct at all. Consistent move-in and move-out photos are now not just good practice; they protect the deduction itself.
Electronic returns and statements
California also modernized how deposits come back. Where a deposit was paid electronically, it can be returned electronically, and the itemized statement can be emailed along with the required photos. Owners and tenants can agree to non-standard arrangements, and in multi-tenant situations each tenant can receive their share. The 21-day deadline still applies regardless of the method.
What still voids a deduction
The fundamentals have not changed: you may deduct for unpaid rent, cleaning to return the unit to its move-in condition, and repair of damage beyond ordinary wear and tear, but not for normal wear. Deductions that lack documentation, arrive after the 21-day window, or ignore the new photo requirement are the ones that fail. When a tenant disputes a withholding, careful records are what protect you.
