Introduction to Security Deposits for Property Managers

Security deposits are a standard feature of renting residential properties in California, acting as a financial safeguard for landlords against potential damages or unpaid rent.

With the passage of Assembly Bill 12, effective July 1, 2024, California has introduced a significant change to its security deposit laws, capping security deposits at one month’s rent for both furnished and unfurnished rental properties.

This new law is designed to ease the upfront financial burden on tenants while still offering landlords protection against losses. For both landlords and tenants, understanding the updated security deposit requirements is essential for compliance and for preventing misunderstandings or disputes.

Staying informed about the latest legal requirements ensures that all parties can navigate the rental process smoothly and confidently.

Overview & New Deposit Limits (AB 12, 2024)

California’s security deposit laws for residential rental properties set some of the country’s strongest renter protections and, as of July 1, 2024, Assembly Bill 12—a law limiting security deposits and recent legislation—has made big changes to what landlords can collect under California’s security deposit limits.

• Standard Limit: Most California landlords can’t collect more than one month’s rent as a security deposit—whether the rental is furnished or unfurnished. The new law standardizes security deposit limits for both furnished and unfurnished units; previously, furnished units had higher limits than unfurnished units.
• Small Landlord Exception: If you own no more than two residential rental properties totaling four or fewer rental units, you may qualify for an exception and collect up to two months’ rent as a deposit. To qualify, the owner must be a natural person, a family trust, or a limited liability company in which all members are natural persons.
• Service Members: The one month’s limit always applies regardless of landlord type.

Example: Large landlords and those renting to service members are always capped at one month. If you’re a small landlord renting to a non-service member, you may collect two months’ rent as a deposit.​

Landlords should review their current security deposit policies and procedures to ensure compliance with the new law, as there are exceptions for small landlords and service members.

Deposit Returns, Deductions, and Documentation

Returning Security Deposits: Timelines & Rules

• The security deposit return process must be completed within 21 calendar days after the tenant moves out.
• All deductions must be detailed in an itemized statement provided to the tenant.

Allowable Deductions

• Landlords may deduct amounts from the security deposit for unpaid rent, necessary repairs (excluding normal wear and tear), and cleaning needed to restore the property to its original condition.

Required Documentation

• For deductions over $125, landlords must provide receipts/invoices and photos documenting condition and repair.​
• If landlord or employees do the repair, must include the hourly rate (which must be reasonable).

Pre-Move-Out Inspection

• Tenants are entitled to request a pre inspection of the rental unit in advance to identify and resolve potential deductions before vacating.
• Landlords must provide at least two weeks’ notice for this inspection. An initial inspection may also be conducted at the start of the tenancy to document the condition of the rental unit and help prevent disputes over deductions.

Security Deposit Collection and Storage

• No requirement for deposits to be held in separate bank accounts or interest-bearing accounts under state law.
• Some cities, like San Francisco and Los Angeles, require interest to be paid—check local ordinances.​

Failure to Comply

• If any portion is withheld without proper documentation or written notices, or deadlines are missed, landlords forfeit the right to withhold. If the landlord retained the entire security deposit in bad faith, the tenant may pursue legal action.
• Non-compliance can result in court awards of the withheld deposit plus up to twice the amount as damages. Tenants can file a claim in small claims court or civil court to recover their entire security deposit if the landlord fails to return it as required by law.

Penalties for Mishandling Deposits

• Up to twice the amount wrongfully withheld plus the original deposit may be awarded to tenants, especially for “bad faith” actions.
• Court costs, attorney’s fees, and even triple damages possible for egregious violations.

Tax and Financial Implications

Security deposits in California come with important tax and financial considerations for landlords. Under California law, the way security deposits are collected, retained, and returned can have direct tax implications.

For example, if a landlord retains part or all of a security deposit to cover unpaid rent, damages, or other allowable costs, the amount kept may be considered taxable income.

In cases where the retained amount exceeds $600 in a calendar year, landlords are required to issue IRS Form 1099-MISC to the tenant.

Additionally, landlords should be aware that retaining a security deposit in bad faith, such as making improper deductions or failing to return the deposit on time, can result in significant additional damages, including penalties and legal costs.

By understanding the tax and financial implications of security deposit collection practices and ensuring compliance with California security deposit laws, landlords can avoid costly disputes and maintain good standing with both tenants and tax authorities.

Overview of California Legal Codes

California Civil Code § 1950.5

Landlords must strictly adhere to California’s legal requirements for collecting and returning security deposits, including compliance with security deposit limits and understanding exceptions under the law limiting security deposits, or risk penalties and forfeiture of any withheld amounts.

Cal. Civ. Code § 1950.5

• Under the new law, California limits security deposits to one month’s rent for both furnished and unfurnished units, with exceptions for small landlords.
• Previously, the law distinguished between furnished and unfurnished units, allowing higher deposits for furnished units, but now the same one month’s rent limit applies to both.
• There is no requirement for landlords to store deposits in a separate or interest-bearing account.
• While not required to disclose the bank holding the deposit, landlords must maintain proper accounting and provide documentation upon return.

Cal. Civ. Code § 1950.5(c)

• Landlords must return the deposit within 21 calendar days of the tenant vacating the unit. When returning security deposits, landlords are required to provide an itemized statement explaining any deductions made.
• Landlords may deduct only allowable costs such as unpaid rent, repairs, and cleaning necessary to return the unit to its original condition, and must provide an itemized statement for any deductions. The cost of repairs must be reasonable, and landlords cannot deduct for normal wear and tear.
• If any portion of the deposit is withheld, a written itemized list of deductions must be provided. For deductions exceeding $125, landlords are required to include copies of invoices or receipts for repairs, and if the work is performed by the landlord or their employee, the hourly rate charged must be included and must be reasonable. As of recent legal updates, landlords must also include photos documenting the condition and reasons for the deductions.
• Before a tenant moves out, tenants have the right to request a pre inspection (also called an initial inspection) to identify potential deductions. Landlords must provide notice of the initial inspection at least two weeks before the tenant moves out.

Cal. Civ. Code § 1950.5(g)(2)

• Some cities, like San Francisco and Los Angeles, require landlords to pay interest on deposits. State law does not mandate interest.
• Not required by state law but strongly recommended. Some local ordinances may require it.
• Tenants have the right to request a pre-move-out inspection to identify potential deductions and correct issues before vacating. Property managers often conduct these inspections and play a key role in ensuring compliance with security deposit collection practices and legal requirements.
• If landlords fail to provide required photos, receipts, or notices, they may forfeit the right to withhold any portion of the deposit.

Landlords should review their property management procedures and security deposit collection practices regularly to ensure compliance with current legal requirements and avoid potential legal issues.

Cal. Civ. Code § 1950.5(f)-(g)

California law strictly enforces penalties for mishandling deposits.

• Failure to return the deposit within 21 days or to provide complete documentation may result in the landlord being liable for up to twice the amount wrongfully withheld, plus the original deposit.
• Failure to include required photos or invoices when deducting over $125 may lead to forfeiture of the withheld amount.

If a landlord retained a security deposit in bad faith, tenants may be entitled to additional damages and can pursue legal action in small claims court or civil court. Tenants can sue for the entire security deposit and additional damages if the landlord fails to comply with security deposit return requirements.

Cal. Civ. Code § 1950.5(l)

• Deposits are capped at two months’ rent for unfurnished units and three months for furnished units.
• Recent legislation, such as AB 12, has changed security deposit requirements, impacting both landlords’ investment strategies and property management practices.
• Deposits must be returned within 21 days, with detailed itemized deductions.
• Photos and receipts must be included for deductions over $125.
• Interest is required in some cities, but not under state law.
• Non-compliance can lead to triple damages, including the full deposit and twice the amount wrongfully withheld.

Key Takeaways

• Documentation: Receipts, invoices, photos for deductions >$125.
