Can My Landlord Charge a Pet Deposit on Top of a Security Deposit in California?

In California, a landlord cannot charge a pet deposit that pushes your total deposit balance above the legal limit. As of July 1, 2024, state law caps total security deposits at one month's rent for most properties, and any pet deposit is legally considered part of that cap. If your landlord is overcharging you, you have legal paths to demand a refund or sue for statutory damages.

What the Law Says in California

Under California Civil Code Section 1950.5, 'security' is broadly defined to cover any payment, fee, deposit, or charge collected at the start of a tenancy to cover defaults in rent or physical damage to the property. This means that legally, there is no separate category for a 'pet deposit'—any refundable fee you pay for your pet is legally treated as part of your overall security deposit.

This distinction became critical on July 1, 2024, when California Assembly Bill 12 (AB 12) took effect. AB 12 amended Civil Code Section 1950.5 to cap the maximum security deposit most landlords can collect at a single month's rent, regardless of whether the unit is furnished or unfurnished. Because pet deposits are legally categorized as security deposits, they must fit inside this overall one-month cap.

For example, if your monthly rent is $2,500, the maximum total deposit your landlord can collect is $2,500. They cannot legally charge a $2,500 standard security deposit and then demand an additional $500 pet deposit on top of that, as this would bring the total upfront deposit to $3,000, violating the state cap.

Exceptions, Pet Rent, and Support Animals

There is a narrow exception to the one-month cap for 'small landlords' under Civil Code Section 1950.5(c)(4). If your landlord is a natural person (or an LLC where all members are natural persons) and owns no more than two residential rental properties that collectively contain four or fewer units, they can charge up to two months' rent as a total deposit. However, they cannot use this exception if you are an active-duty military service member.

While California law heavily restricts upfront pet deposits, it does not outlaw monthly 'pet rent'. Landlords are generally permitted to charge an additional monthly recurring fee for housing a pet, as long as it does not violate local rent control ordinances. However, any such fee must be true rent, not a disguised refundable deposit or a one-time non-refundable fee. Under Civil Code Section 1950.5(m), no part of a security deposit can ever be declared non-refundable.

Additionally, if your animal is a legally documented Service Animal or Emotional Support Animal (ESA), they are not legally considered pets under federal and state fair housing laws, such as the California Fair Employment and Housing Act (FEHA). Landlords cannot charge any pet deposit, pet fee, or pet rent of any kind for a verified service or support animal, regardless of their deposit cap.

What You Can Do Next to Protect Yourself

If your landlord has demanded or already collected an illegal pet deposit that exceeds California's strict limits, you do not have to accept the violation. The first and most effective step is to formally notify them in writing. Many landlords and property management companies are either unaware of the AB 12 amendments or assume tenants won't double-check the law. Providing them with a formal written notice citing Civil Code Section 1950.5 often prompts a swift correction or refund.

If the landlord refuses to comply, you can pursue the excess funds through California Small Claims Court. Under Civil Code Section 1950.5(l), a landlord who wrongfully and in bad faith claims or retains a security deposit can be held liable for actual damages plus statutory damages of up to twice the amount of the security deposit. This means a landlord trying to squeeze an extra illegal deposit out of you could end up paying a heavy financial penalty.

Steps

• Calculate your maximum legal deposit by checking your monthly rent amount and verifying if your landlord qualifies for the small landlord exception (no more than 2 properties / 4 units total).
• Review your lease agreement to identify how the landlord has labeled and itemized the security deposit, pet deposit, or any other upfront fees.
• Draft a polite but firm written demand letter citing California Civil Code Section 1950.5 and AB 12, requesting that they adjust the lease terms or refund any deposit collected in excess of the one-month cap.
• Keep strict records of all communications, lease drafts, receipts, and pet documentation in a secure location as evidence in case you need to file a claim in small claims court.

Common mistakes

• Assuming a 'non-refundable pet fee' is legal—California Civil Code Section 1950.5(m) explicitly outlaws non-refundable deposits or upfront fees of any kind.
• Paying an illegal deposit first with the plan to fight it later without getting the agreement in writing or establishing a paper trail.
• Conflating an Emotional Support Animal (ESA) with a standard pet, which leads to paying illegal deposits or pet rent for an exempt assistance animal.

Questions people ask

Can my landlord charge monthly pet rent on top of my rent?

Yes. While California's AB 12 limits upfront security deposits (including pet deposits) to one month's rent, it does not ban monthly pet rent. Landlords can charge a reasonable monthly recurring pet rent, provided it complies with local rent control laws and is not charged for an ESA or service animal.

What happens if I signed my lease before July 1, 2024?

The AB 12 cap of one month's rent only applies to leases signed, renewed, or extended on or after July 1, 2024. If your lease was signed prior to that date, the old limits (up to two months' rent for unfurnished units) remain legally valid until your lease is renewed or a new agreement is drafted.

Do I have to pay a pet deposit for my Emotional Support Animal (ESA)?

No. Under California's Fair Employment and Housing Act (FEHA) and the federal Fair Housing Act, ESAs and service animals are assistance animals, not pets. Landlords are strictly prohibited from charging any pet deposits, pet fees, or monthly pet rent for a verified assistance animal.
