How Much Security Deposit Can I Charge in California?

Under California AB 12 (effective July 2024), residential security deposits are generally limited to one month's rent, regardless of whether the unit is furnished or unfurnished. A limited exception allows small landlords (those owning no more than two residential rental properties totaling no more than four units) to charge up to two months' rent, but only if the tenant is not a service member. Deposits cannot include separate non-refundable "pet deposits" or other non-refundable charges. All deposits must be held in trust and returned per the 21-day statutory process.

What follows is the complete framework for security deposit amounts, structures, and best practices.

The Current California Cap: AB 12

Effective July 1, 2024, California AB 12 substantially reduced security deposit caps:

Standard cap: One month's rent for both furnished and unfurnished units

Small landlord exception: Landlords who own no more than two residential rental properties, collectively containing no more than four dwelling units, may charge up to two months' rent, but only for non-servicemember tenants

Servicemember exception: For servicemember tenants (active duty military), the cap is one month's rent regardless of landlord size

This is a significant change from prior law, which allowed up to two months for unfurnished and three months for furnished units.

Who Qualifies for the Small Landlord Exception

The exception applies to landlords who meet ALL of the following:

1. Owns no more than two residential rental properties
2. Those properties collectively contain no more than four dwelling units
3. Ownership is by a natural person, family trust, or LLC where all members are natural persons

If you own three or more properties, or if your holdings contain more than four total units, the exception does not apply, even if the specific property being rented is a single-family home.

Corporate and institutional owners generally do not qualify.

Non-Refundable Fees Are Not Permitted

California does not permit non-refundable pet deposits or other non-refundable charges labeled as security. All security-related deposits must be refundable subject to lawful deductions per Civil Code 1950.5.

Some landlords attempt to charge:

• Non-refundable pet deposits
• Non-refundable cleaning fees
• "Pet cleaning" charges labeled as non-refundable

None of these are enforceable. They must either be structured as refundable deposits within the cap or removed entirely.

Ongoing monthly pet rent is different and is generally permitted.

---

What Deposits Cover

Security deposits under California law can be used for:

1. Unpaid rent
2. Damage beyond normal wear and tear
3. Necessary cleaning to restore move-in condition
4. Other costs specifically authorized in the lease

These are the only permitted deduction categories. See our companion article on security deposit deductions for detailed treatment.

Practical Application on the Peninsula

Example 1: Standard Carmel rental

Owner has three rental properties. Cap is one month's rent.

Rent: $6,000/month Maximum deposit: $6,000

Example 2: Small landlord with two properties

Owner has one single-family rental and one condo (two total properties, two total units). Tenant is not a servicemember. Small landlord exception applies.

Rent: $5,500/month Maximum deposit: $11,000

Example 3: Small landlord, servicemember tenant

Same owner as example 2, but tenant is active duty military. Exception does not apply for servicemembers.

Rent: $5,500/month Maximum deposit: $5,500

Example 4: Furnished mid-term rental

Owner has multiple properties. Furnished 30-day+ rental at $10,000/month.

Rent: $10,000/month Maximum deposit: $10,000 (furnished status no longer allows higher deposit)

Setting the Deposit Amount

Even where a higher deposit is legally permitted, market considerations affect what deposit level makes sense.

Arguments for maximum deposit:

• Higher protection against damage and unpaid rent
• Better filter for financially prepared tenants
• Cushion for larger properties with higher potential loss exposure

Arguments for lower deposit:

• Broader applicant pool
• Faster leasing
• Less friction at move-in

For most Peninsula rentals, one month's deposit is the standard, driven by both AB 12 and market norms. Owners who qualify for the two-month exception often still choose one month's deposit for market competitiveness.

---

Alternatives to Larger Deposits

For situations where higher risk protection is desired but a larger deposit is not available, alternatives include:

Higher qualifying criteria. Screening for higher credit scores, income ratios, and rental history reduces risk without requiring larger deposits.

Co-signers or guarantors. For borderline applicants, a co-signer provides additional recourse.

Renters insurance requirement. With adequate liability coverage.

Pet rent structure. Monthly ongoing charge rather than upfront deposit.

More thorough screening. In-person interviews, more extensive rental history verification.

These alternatives collectively can provide risk protection equivalent to (or better than) a higher deposit.

Managing Deposits in Compliance

California requires proper handling of security deposits during the tenancy:

• Deposits must be held in trust (not commingled with operating funds)
• Property managers must hold deposits in broker trust accounts (California Business & Professions Code)
• Interest on deposits is generally not required in most California jurisdictions (some local ordinances differ)
• Deposits should be documented in writing at the start of tenancy

At Cypress & Pine, deposits are held in a broker trust account per California law. This is a required practice for licensed property managers.

---

What Happens at Move-Out

Regardless of deposit amount, the 21-day return process applies. See our companion article on security deposit deductions for detailed treatment. Key points:

• Itemized deductions within 21 days of vacating
• Receipts for deductions over $125
• Return of any remaining balance
• California penalties for non-compliance

Failure to properly handle the move-out return can result in forfeiture of any deductions and statutory damages.

Common Questions

Can I ask for the last month's rent up front separately?

Yes, but the "last month's rent" is treated as part of the security deposit for cap purposes. So if rent is $6,000 and you take $6,000 as last month's rent, you cannot take additional security deposit.

Can I require certified funds for the deposit?

Yes, this is common practice and permitted.

What about a pet deposit specifically?

Any pet-related deposit is included in the total deposit cap. There is no separate pet deposit allowance.

Can I increase the deposit if the tenant renews?

Under limited circumstances. This is legally complex and often creates fair housing questions. Consult an attorney before implementing.

What if the tenant pays more than the cap voluntarily?

You still cannot legally retain more than the statutory cap. Excess must be refunded.

The Cypress & Pine Approach

For properties we manage, security deposit handling includes:

• Cap verification based on owner circumstances (property portfolio, servicemember status)
• Compliant deposit collection
• Broker trust account holding (required under California license)
• Full move-in inspection documentation (baseline for future disputes)
• Move-out processing with itemization
• 21-day return of any balance

Our approach reflects the current AB 12 requirements. Owners with holdings that qualify for the small landlord exception can choose to charge up to two months, though we generally recommend one month as the market-competitive standard.
