Pet policies used to be one of the easier parts of running a rental—charge a separate pet deposit, maybe pet rent, and move on. California's security deposit rules have changed that math, and landlords who haven't revisited their pet fee structure recently may be charging more than the law allows.
Pet Deposits Count Toward the Overall Deposit Cap
Under AB 12, California caps most residential security deposits—including any pet deposit—at one month's rent total for most landlords (with a narrow exception letting certain small landlords charge up to two months' rent under specific conditions). A pet deposit is not a separate bucket outside this cap; it's part of the same overall limit. Charging a full-cap general deposit and adding a separate pet deposit on top very likely exceeds the statutory cap.
Non-Refundable Pet Fees Are Legally Risky
California doesn't clearly authorize non-refundable pet fees as a category separate from the security deposit. Any upfront payment tied to a pet that isn't clearly rent is generally treated as a security deposit under Civil Code §1950.5—meaning it must be refundable, subject to the same 21-day return and itemization rules, and counted against the overall cap.
Monthly Pet Rent Is a Safer Structure
Because deposit-style pet charges are capped and refundable, many landlords have shifted to monthly pet rent instead—an ongoing add-on to base rent rather than an upfront deposit. Pet rent isn't subject to the deposit cap, though it does count toward gross rent for AB 1482's rent increase calculations, so it should appear clearly in the lease as its own line item.
Service and Assistance Animals Are a Separate Category
Fees, deposits, and pet rent generally cannot be charged for service or emotional support animals, since these are treated as a reasonable accommodation rather than a pet. A landlord can still hold a tenant responsible for actual damage the animal causes—through the normal deduction process at move-out, not an upfront charge.
Building a Compliant Pet Policy
- Keep any pet-related deposit within the same one-month cap—never stacked on top
- Use monthly pet rent, not a non-refundable fee, if additional recurring revenue is the goal
- Clearly exempt service and assistance animals from all pet-related charges
Bottom Line for Landlords
- A separate pet deposit on top of a full-cap deposit is very likely a violation
- Non-refundable pet fees carry real legal risk under Civil Code §1950.5
- Monthly pet rent is the more defensible structure
- Never charge fees, deposits, or pet rent for a service or assistance animal
FAQ
Can a landlord charge a separate pet deposit in addition to the security deposit?
Not really—under AB 12, a pet deposit is generally treated as part of the same overall security deposit cap, not an additional amount on top of it.
Are non-refundable pet fees legal in California?
They're risky. Amounts collected upfront for a pet are generally treated as part of the refundable security deposit under Civil Code §1950.5, regardless of how the fee is labeled.
Can a landlord charge pet rent for an emotional support animal?
No—assistance animals are treated as a reasonable accommodation, not a pet, so landlords generally cannot charge pet rent, pet deposits, or pet fees for them.
Keep rent, deposit, and pet rent separated correctly
LeaseConnectPro's lease templates separate rent, security deposit, and pet rent into distinct fields, so the deposit cap is never accidentally exceeded.
