California Security Deposit Laws

January 8, 2026

Key Takeaways

  • Security deposit limits have changed. As of July 1, 2024, most California landlords may collect no more than one month’s rent as a security deposit, regardless of whether the unit is furnished, with limited exceptions for small property owners.
  • Deposits must be handled and deducted properly. Landlords may only deduct for approved reasons such as unpaid rent, damage beyond normal wear and tear, cleaning, or unauthorized alterations, and must keep deposits available for return after move out.
  • Strict return deadlines and penalties apply. Any remaining security deposit must be returned within 21 days of move out along with an itemized statement if deductions are made, or landlords risk significant financial penalties for late or improper returns.

As a landlord in California, long term success begins with a clear understanding of your legal responsibilities, including the state’s security deposit rules. 

Knowing how to properly collect, hold, and return security deposits can help you avoid costly mistakes, missed deadlines, and disputes with residents. 

In this guide by Keyrenter Contra Costa, you will learn the essentials of California security deposit law so you can manage deposits confidently, stay compliant, and protect your investment.

Maximum Security Deposit Law

Before July 1, 2024, the maximum security deposit a landlord could charge in California depended on whether the rental unit was furnished or unfurnished. For unfurnished units, the limit was two months’ rent. For furnished units, landlords could charge up to three months’ rent.

This changed with the passage of Assembly Bill 12, which took effect on July 1, 2024. Under the new law, landlords may collect a maximum security deposit equal to one month’s rent, regardless of whether the unit is furnished or unfurnished.

There is a limited exception to this rule. Landlords who own no more than two rental properties with a combined total of four units may collect up to two months’ rent as a security deposit.

Additional Pet Deposits

California landlords are generally allowed to charge an additional deposit for residents who have pets. However, residents with assistance animals must be exempt from pet deposits. 

Assistance animals include service animals and emotional support animals and are protected under federal fair housing laws.

Landlords must also make reasonable accommodations for residents with disabilities, even if the investment property has policies that would otherwise restrict pets or access. 

Examples of reasonable accommodations may include:

  • Assigning an accessible parking space even when parking is first come, first served.
  • Adjusting rent payment dates to align with disability income payments.
  • Allowing a resident with a mobility impairment to move to a ground floor unit.
  • Providing notices in accessible formats such as electronic copies, large print, or braille.

Security Deposit Storage

California law does not require landlords to store security deposits in a specific type of account or to provide notices about where the deposit is held. Landlords are not required to use interest bearing accounts.

The primary requirement is that the funds remain available and intact so they can be returned to the resident after move out, minus any lawful deductions.

Security Deposit Deductions

Landlords in California may make deductions from a security deposit for specific, allowable reasons, including:

  • Covering damage that goes beyond normal wear and tear.
  • Unpaid rent owed under the lease agreement.
  • Cleaning costs needed to return the unit to the same level of cleanliness as at move-in.
  • Replacing items listed in the lease that the resident removed.
  • Restoring the unit after unauthorized alterations.

However, landlords may not deduct for pre-existing conditions that existed before the resident moved in, damage caused by the landlord’s failure to properly maintain or repair the property, normal wear and tear such as faded paint or loose doorknobs, or costs related to upgrading or improving the unit.

Security Deposit Returns

California law sets a strict deadline for returning a resident’s security deposit. Any remaining portion must be returned within 21 days after the resident moves out. If deductions are made, the landlord must also provide an itemized statement detailing those deductions within the same time frame.

Failure to return the deposit on time can result in significant penalties. A landlord who misses the deadline may be required to return the full amount wrongfully withheld. If a court determines the deposit was withheld in bad faith, the landlord may be liable for up to twice the amount of the security deposit.

Conclusion

Security deposits are a highly regulated part of renting property in California, and landlords must follow the rules carefully to avoid disputes and legal penalties. 

Understanding how much you can charge, how deposits may be used, and when they must be returned is essential for protecting your investment and maintaining positive resident relationships.

Keyrenter Contra Costa handles 21-point tenant screening, online rent collection, 24/7 emergency maintenance coordination, routine inspections, move-in and move-out documentation, and financial reporting through AppFolio.

If a tenancy ends in an eviction, full service management also includes coordinating the eviction process rather than leaving the owner to handle it alone. 

If a placed tenant breaks the lease within the first six months, Keyrenter Contra Costa will re-lease the property at no charge.

For owners who want ongoing support after a property is leased, full service management keeps rent collection, maintenance, inspections, documentation, and other day-to-day responsibilities with a dedicated property manager rather than placing them back on the owner’s plate.

Fee Structures: Leasing-Only vs Full Service

Leasing-only pricing is typically a single, one-time fee tied to securing a signed lease. After that, the owner is responsible for ongoing tasks such as rent collection, maintenance, and turnover.

Full service pricing is usually an ongoing management fee based on a percentage of collected rent, paid while the manager actively oversees the property. 

Management fees commonly range from a small percentage to several percentage points of monthly rent, depending on the services provided, property type, and market. Keyrenter Contra Costa publishes its plans and guarantee conditions on its pricing page, while exact pricing is discussed during a consultation.

The cost difference can become more significant when a property experiences vacancy, maintenance issues, or turnover. Leasing-only may have a lower upfront cost, but it does not cover the ongoing responsibilities that come with managing a rental after move-in.

How to Decide: A Decision Matrix for San Ramon Investors

Leasing-only pricing is typically a one-time fee for securing a signed lease agreement. After move-in, the owner handles rent collection, maintenance, and turnover.

Full service usually involves an ongoing fee based on a percentage of collected rent. Rates vary by property and services, with exact pricing discussed during a consultation.

Portfolio Size

One door and a local owner willing to self-manage after placement often leans toward leasing-only. Two or more doors, especially spread across San Ramon, Danville, or Pleasanton, usually makes full service more practical simply because coordinating multiple maintenance calls and lease renewals solo gets harder fast.

Owner Involvement and Location

An owner who lives in the Tri-Valley and wants to stay involved might choose leasing-only and handle the rest themselves. An owner who relocated out of state, or who simply doesn’t want a 2 a.m. call about a burst pipe, needs full service.

Risk Tolerance and Asset Value

A higher-value San Ramon home, particularly one in the $700,000 to $2 million range that the brief identifies as typical for the area, carries more downside from a bad tenant, an unresolved maintenance issue, or an eviction handled incorrectly.

Full service’s guarantee stack, including the 30-day leasing guarantee, the six-month tenant guarantee, and rental eviction cost coverage, exists specifically to offset that downside.

Bottom Line

The choice between leasing-only and full service depends on how involved you want to be after a lease is signed. 

Leasing-only suits owners who prefer to self-manage, while full service provides ongoing support with rent collection, maintenance, inspections, and other responsibilities. Keyrenter Contra Costa helps San Ramon owners choose the approach that best fits their property.

Frequently Asked Questions

Can I Switch From Leasing-Only To Full Service Later?

Yes, an owner may be able to transition an existing rental to full service management after the property has been leased. The manager would typically review the existing lease, property condition, tenant history, and current management needs before taking over. 

Confirming the transition process and any applicable fees with the property management company can help avoid gaps in service.

What Happens If A Leasing-Only Tenant Stops Paying Rent?

With leasing-only management, the owner generally becomes responsible for addressing unpaid rent once the leasing service ends. 

That may include communicating with the resident, following required notice procedures, and deciding whether further action is necessary. Owners who prefer not to handle these issues themselves may want ongoing management that includes rent collection and eviction coordination.

Is Full Service Property Management Worth It For One Rental Property?

It can be, depending on how much time the owner has and how involved they want to be. A local owner who is comfortable handling maintenance, rent collection, and resident communication may prefer leasing-only. 

An owner who wants those responsibilities handled on their behalf may find full service worthwhile even with a single property.

What Should I Ask Before Choosing A Property Management Service?

Ask exactly where the service begins and ends, what happens after a lease is signed, how maintenance and emergencies are handled, what fees apply, and how the agreement can be canceled. 

Owners should also confirm whether inspections, rent collection, eviction coordination, financial reporting, and other ongoing services are included or billed separately.
