California Security Deposit
Return Calculator

California limits security deposits to 1 month’s rent for large landlords (3+ units); 2 months’ rent for small landlords (≤2 units, unfurnished); 3 months’ rent for furnished units (Cal. Civ.

Code § 1950.5 as amended by AB 12, eff. July 2024) and requires landlords to return the deposit within 21 days after a tenant moves out.

The state does not require landlords to pay interest on security deposits. These rules are established by Cal.

Civ. Code § 1950.5.

Landlords who miss the 21 days return window or make unsupported deductions face penalties: tenant may recover up to double the deposit for bad faith retention plus actual damages. Both tenants disputing withheld funds and landlords defending deductions benefit from knowing exactly what California law allows and requires.

California's AB 12 (eff. July 1, 2024) reduced the deposit cap to 1 month's rent for landlords with 3+ units — a major change from the prior 2-month cap.

San Francisco, Los Angeles, and several other cities have local rent control ordinances that may impose additional deposit restrictions or require just-cause eviction, which indirectly affects deposit disputes. California's pre-move-out inspection requirement (Cal.

Civ. Code § 1950.5(f)) is mandatory — landlords must offer tenants a walk-through 2 weeks before move-out and provide a written itemized list of deficiencies that the tenant may address before vacating.

Small claims court limit is $12,500. Service animals cannot be charged pet deposits under state FEHA and federal law.

Under Cal. Civ.

Code § 1950.5, California limits security deposits to 1 month’s rent for large landlords (3+ units); 2 months’ rent for small landlords (≤2 units, unfurnished); 3 months’ rent for furnished units (Cal. Civ.

Code § 1950.5 as amended by AB 12, eff. July 2024).

This cap applies to the security deposit itself and typically does not include last month's rent, pet deposits, or other fees that may be collected separately under California law. Landlords who collect more than the statutory maximum may be required to reimbursement the excess and could face additional penalties.

The deposit limit in California is designed to prevent landlords from demanding excessive upfront payments that create barriers to housing access. For a rental with monthly rent of $1,500, the maximum security deposit under California law would be calculated based on the 1 month’s rent for large landlords (3+ units); 2 months’ rent for small landlords (≤2 units, unfurnished); 3 months’ rent for furnished units (Cal.

Civ. Code § 1950.5 as amended by AB 12, eff.

July 2024) formula. Tenants should verify that the total amount collected at move-in does not exceed the statutory cap, and should request a receipt documenting the deposit amount, the date paid, and the account where the deposit is held.

California tenants should be aware that security deposits are separate from other move-in costs. Application fees, pet fees, cleaning deposits, and last month's rent are distinct charges that may or may not be subject to separate regulations.

Read your lease carefully to understand exactly what each payment covers and whether it is reimbursable.

California law requires landlords to return security deposits within 21 days after the tenant vacates the rental unit. This deadline is strict — California's return window is shorter than the national average, which falls around 30 days.

The clock typically starts when the tenant surrenders possession of the unit and returns all keys.

Along with the deposit (or any remaining balance after deductions), the landlord must provide an itemized written statement listing each deduction. California law specifically requires this itemization, and failure to provide it within the statutory window can result in the landlord forfeiting the right to retain any portion of the deposit.

Each deduction must be documented — vague entries like "cleaning" or "damages" without specifics are generally insufficient.

To protect your rights as a tenant in California, always provide your landlord with a forwarding address in writing when you move out. Some states require the forwarding address before the return deadline begins to run.

Take date-stamped photos or video of the unit at both move-in and move-out to document the property's condition. If the landlord fails to return the deposit or provide an itemization within 21 days, send a written demand letter via certified mail before pursuing legal action.

Under California law, landlords may deduct from the security deposit for the following: unpaid rent, cleaning to restore to move-in condition, repair of damage beyond normal wear and tear, restoration of personal property if lease allows. These deductions must be reasonable, documented, and itemized in the statement provided to the tenant.

Landlords cannot deduct for normal wear and tear — this is a critical distinction that is frequently disputed between landlords and tenants.

Normal wear and tear in California generally includes minor scuffs on walls, worn carpet from everyday foot traffic, small nail holes from hanging pictures, faded paint due to sunlight exposure, and minor door or window wear. Damage beyond normal wear includes large holes in walls, stained or burned carpet, broken windows, unauthorized modifications, pet damage, and excessive filth requiring professional cleaning.

The line between wear and damage is not always clear, which is why move-in and move-out condition documentation is critical.

California is one of only 6 states that require or strongly encourage a walk-through inspection before the tenant moves out. This inspection gives the tenant an opportunity to address any issues the landlord identifies before the final move-out, potentially reducing or eliminating deductions from the deposit.

If your landlord offers a walk-through, take advantage of it — and bring a checklist and camera to document the unit's condition during the inspection.

California does not require landlords to pay interest on security deposits. No statewide requirement; some local ordinances (SF, LA, West Hollywood) require interest.

This places California in the majority — only 14 of 51 jurisdictions require deposit interest. While tenants do not earn interest on their deposits in California, they still have full rights to the return of the principal amount, less any lawful deductions.

Even without an interest requirement, California tenants should be aware that their deposit money is being held for the duration of the lease. This represents a real opportunity cost, particularly for larger deposits.

When negotiating a lease in California, consider whether the deposit amount is reasonable relative to the monthly rent and whether any of the upfront costs can be reduced.

California does not require landlords to hold security deposits in a separate or escrow account. This means a landlord may commingle the deposit with personal or business funds, which carries some risk for tenants if the landlord faces financial difficulties.

Approximately 16 jurisdictions require separate accounts for deposit funds. California tenants may want to ask their landlord where the deposit is being held, even though disclosure is not always required by law.

The penalties for security deposit violations in California are significant. Under Cal.

Civ. Code § 1950.5: tenant may recover up to double the deposit for bad faith retention plus actual damages.

These penalties apply when a landlord fails to return the deposit within the statutory deadline, makes improper deductions, or fails to provide the required itemized statement.

California's double-damages provision means that a landlord who wrongfully withholds a $2,000 security deposit could owe $4,000 to the tenant, plus any attorney fees and court costs awarded. This penalty applies when the landlord's withholding is found to be willful or in bad faith — an honest mistake in calculating deductions may not trigger the penalty multiplier, but failing to return the deposit at all almost certainly will.

To pursue a security deposit claim in California, tenants typically file in small claims court, which handles disputes up to a specified dollar amount without requiring an attorney. The process involves filing a complaint, paying a small filing fee, and presenting evidence at a hearing.

Key evidence includes the lease, proof of deposit payment, move-in and move-out photos, the landlord's itemized deductions statement (or lack thereof), and any correspondence about the deposit. Many California courts also offer mediation services that can resolve deposit disputes faster than a full hearing.

Security deposit disputes are often part of a broader landlord-tenant conflict. If the dispute escalates to eviction, the California Eviction Timeline Calculator shows notice periods and court timelines by cause of action.
