California Security Deposit Return Law & Calculator

1. The 21-Calendar-Day Return Rule (Cal. Civ. Code § 1950.5(h)(1))

Under California Civil Code § 1950.5(h)(1), housing providers have a mandatory window of exactly 21 calendar days to return a tenant's security deposit. The clock begins on the calendar day the tenant vacates the property and turns over possession (returns all keys).

Within this 21-day period, the landlord must provide:

• A full refund of the deposit, OR
• An itemized statement listing each specific deduction, the remaining balance, and a refund check for the remainder.

Delivery may be completed by personal delivery, first-class mail postage prepaid, or by electronic deposit if both parties previously consented in writing.

2. The $125 Itemized Receipt Requirement (Cal. Civ. Code § 1950.5(h))

California has one of the strictest documentation requirements in the United States. Under subdivision (h), if total deductions for repairs and cleanings exceed $125, the landlord is legally required to attach copies of supporting documents:

• Outside Contractors: If third-party vendors or cleaning services performed the work, the landlord must attach copies of the contractor's itemized bill or invoice, including the contractor's name, address, and phone number.
• In-House Employees: If the landlord or their employees did the work, the statement must detail the time spent, the specific task, and the reasonable hourly rate charged.
• Purchased Materials: If supplies or replacement parts were bought, copies of store receipts or vendor bills must be attached.

If repairs cannot be completed within 21 days due to circumstances beyond the landlord's control, the landlord must provide a good-faith estimate within 21 days and deliver final receipts within 14 calendar days of completion.

3. Photographic Evidence & Cleaning Rules (AB 2801)

Enacted under California Assembly Bill 2801 (effective 2025), significant new statutory requirements govern photographic documentation and cleaning deductions under Civil Code § 1950.5:

• Move-Out Before & After Photos (§ 1950.5(g)(2)): From April 1, 2025, landlords must photograph the rental unit after possession is returned (prior to repairs or cleaning) and again after completing repairs or cleaning to support any deduction.
• Mandatory Move-In Photos (§ 1950.5(g)(1)): For tenancies commencing on or after July 1, 2025, landlords must also take move-in photographs immediately before, or at the inception of, the tenancy to substantiate initial unit condition.
• Cleaning Restriction (§ 1950.5(e)): Landlords cannot charge for professional cleaning unless reasonably necessary to restore the premises to its condition at the inception of the tenancy, ordinary wear and tear excepted.

4. Security Deposit Caps Under AB 12 (Effective July 1, 2024)

Effective July 1, 2024, California Assembly Bill 12 amended Civil Code § 1950.5(c) to establish a standard ceiling on residential security deposits:

5. Tenant Right to an Initial Pre-Move-Out Inspection (§ 1950.5(f))

Under subdivision (f), a housing provider must notify the tenant in writing of their right to request an initial walkthrough inspection within a reasonable time after receiving or delivering a notice to terminate tenancy.

The inspection must take place no earlier than two weeks before the termination date. Following the inspection, the landlord must provide an itemized list of identified repairs or cleaning needed to avoid deductions, giving the tenant an opportunity to remedy those issues before turning over the keys.

6. Normal Wear and Tear vs Unlawful Deductions

Under Cal. Civ. Code § 1950.5(e), landlords are strictly prohibited from using security deposit funds to repair defects resulting from ordinary wear and tear. Deductions are lawful only for:

7. Bad-Faith Penalties: Up to Twice the Deposit (§ 1950.5(m))

If a California landlord retains any portion of a tenant's security deposit in bad faith, subdivision (m) (formerly subdivision (l)) provides that the court may award statutory damages of up to twice the amount of the security deposit, in addition to actual damages.

Examples of bad-faith conduct recognized by California courts include:

• Failing to send any statement or refund within 21 days without a valid legal excuse.
• Inventing inflated or fabricated repair charges.
• Refusing to furnish required receipts for deductions of more than $125 upon request (§ 1950.5(h)).
• Deducting for pre-existing damage noted on the move-in inspection sheet.

8. How to Demand Your Deposit Refund

If your landlord has missed the 21-day statutory deadline or withheld unauthorized deductions without supporting receipts, your recognized first step is delivering a formal demand letter citing California Civil Code § 1950.5.
