California Security Deposit Law: What Your Landlord Can and Cannot Deduct

California Tenant Defense System | Justice Foundation

Security deposit disputes are the most common landlord-tenant conflict in California — and one where tenants most frequently lose money they are legally entitled to recover. California Civil Code Section 1950.5 provides detailed rules governing security deposits, and landlords who violate those rules face significant financial consequences. Understanding the rules before you move out is the key to getting your deposit back.

The Legal Limits on Deductions

California law strictly limits what a landlord can deduct from a security deposit. Permitted deductions include: unpaid rent, damage beyond normal wear and tear, and cleaning costs to restore the unit to the condition it was in at move-in (if it was professionally cleaned at move-in). That’s the complete list. The landlord cannot deduct for normal wear and tear — the gradual deterioration that results from ordinary use over time. Worn carpet from normal foot traffic, minor wall scuffs, small nail holes from pictures, and faded paint are all normal wear and tear, not damage. Deducting for these items is illegal.

The 21-Day Rule

The landlord must return your security deposit — or provide an itemized statement of deductions with supporting documentation — within 21 calendar days of the date you vacate. The itemized statement must include the amount of each deduction, an explanation of what the deduction covers, and copies of receipts or invoices for any repairs or cleaning claimed. A landlord who fails to provide the itemized statement and documentation within 21 days forfeits the right to make any deductions — the entire deposit must be returned.

How to Protect Yourself

Document the condition of the unit at move-in and move-out with photographs and video. Request a pre-move-out inspection — California law requires landlords to offer this at least two weeks before the end of the tenancy if requested. Get a written list of any items the landlord identifies at the pre-move-out inspection so you can fix them before you leave. Return the keys on the lease end date with a forwarding address in writing. The Justice Foundation kit includes move-in and move-out inspection checklists and demand letter templates for recovering wrongfully withheld deposits.
