Pet Deposits, Pet Rent & ESA Rules in California 2026
State pet-deposit treatment, federal Fair Housing Act assistance-animal rules, and what California landlords can and cannot ask.
California treats a household pet and a disability-related assistance animal as two entirely different things, and confusing the two is where most landlords get into trouble. For an ordinary pet you keep wide discretion: you can adopt a no-pet policy, restrict breeds or size, and charge pet rent. For a service animal or emotional support animal (ESA), the animal is a reasonable accommodation under the California Fair Employment and Housing Act (Gov. Code §§ 12927, 12955) and the federal Fair Housing Act, and most of your usual pet rules stop applying.
The Civil Rights Council's assistance-animal regulation (2 CCR § 14331) requires housing providers to grant these requests unless the specific animal poses a direct threat or an undue burden. On top of the federal baseline, California added AB 468 (Health & Safety Code §§ 122317–122319.5), effective January 1, 2022, which sets real standards for the ESA letters tenants rely on. Together these rules define exactly what you can ask, what you can charge, and when you can lawfully refuse.
This page walks through the CA-specific framework a landlord needs before responding to any animal request in 2026.
How California Treats Pet Deposits
Total deposit (including pet deposit) capped at 1 month's rent on or after July 1, 2024 (AB 12). Small landlords (≤ 2 properties / ≤ 4 total units) may charge up to 2 months. Pet deposits are explicitly counted toward the cap.
Recent California Pet-Related Statute
AB 2216 (2024, eff. Jan 1, 2025), for housing receiving covered public assistance, blanket "no pets" policies on new leases are prohibited; landlords cannot ask about animals before a conditional offer.
Service animals vs. ESAs vs. pets
The three categories carry different rights. A service animal under the ADA is a dog (and in limited cases a miniature horse) individually trained to perform tasks for a person with a disability, such as guiding, alerting, or retrieving. An emotional support animal is not task-trained; it provides comfort that eases the symptoms of a diagnosed disability. In housing, California's FEHA and the federal Fair Housing Act protect both as assistance animals, so for rental purposes the practical rights are similar even though the ADA covers only service animals.
An ordinary pet is neither. If the animal is a genuine assistance animal, your pet policies give way; if it is just a pet, you keep your usual discretion over whether to allow it, which breeds, and what to charge.
What you can (and cannot) ask
When a disability and the animal's need are not obvious, you may request reliable documentation that the tenant has a disability and a disability-related need for the animal. You may not demand medical records, a diagnosis, or details about the person's condition.
For a service animal whose need is not obvious, you are limited to two questions: is the animal required because of a disability, and what work or task is it trained to perform. You cannot require certification, registration, an ID card, or a demonstration of the task. Many online 'registries' sell meaningless certificates, and their absence is not grounds to deny a legitimate request.
AB 468 and what a valid ESA letter must show
California's AB 468 (Health & Safety Code §§ 122317–122319.5) tightened the standards for ESA documentation, which helps landlords screen out fraudulent letters. A health care practitioner writing an ESA letter must hold a valid, active license and include the license effective date, number, jurisdiction, and type in the documentation. The practitioner must have completed a clinical evaluation of the individual and must have held a client-provider relationship for at least 30 days before issuing the letter.
Practitioners who sell ESA documentation without meeting these standards face escalating civil penalties of $500 for a first violation, $1,000 for a second, and $2,500 for a third and subsequent violations. If a letter is obviously from an instant online mill with no genuine treating relationship, you have a stronger basis to ask for documentation that complies with AB 468.
Fees, deposits, and pet rent
You may not charge a pet deposit, pet rent, or any extra fee for a service animal or ESA. Assistance animals are accommodations, not pets, so breed, size, and weight restrictions and pet fees do not apply to them. You may still hold the tenant responsible for actual damage the animal causes, charged against the ordinary security deposit like any other damage.
That deposit itself is capped. Under Civil Code § 1950.5, as amended by AB 12 (effective July 1, 2024), most landlords may collect no more than one month's rent as a total security deposit; a small owner (no more than two properties and four total units) may collect up to two months' rent, except that a military service-member tenant is always capped at one month. For ordinary pets that are not assistance animals, you can charge pet rent and set pet policies, but any pet deposit still counts toward that same overall cap.
When you can lawfully deny an animal
A reasonable accommodation is not unconditional. You may deny a specific assistance animal if it would pose a direct threat to the health or safety of others, or would cause substantial physical damage to property, that cannot be reduced by another accommodation. This must rest on the individual animal's actual conduct or history, not on breed, size, or stereotype. You may also deny a request that imposes an undue financial or administrative burden or fundamentally alters your operations, a high bar that is rarely met in ordinary residential housing.
Respond to requests promptly; under California guidance, unreasonable delay can itself be treated as a denial and a form of disability discrimination. Note too that misrepresenting an untrained pet as a service dog is a misdemeanor under Penal Code § 365.7, but that is a matter for enforcement, not a reason to reject a documented request out of hand.
The Cost of Mishandling a California ESA Request
The most common mistake in California ESA cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more documentation than HUD permits, or imposes a pet fee on an accepted assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied on its merits.

Frequently Asked Questions
Can a California landlord charge a pet deposit for an emotional support animal?
No. Service animals and ESAs are reasonable accommodations under FEHA, so you cannot charge a pet deposit, pet rent, or extra fee for them. You may still deduct for actual damage the animal causes from the standard security deposit.
Do I have to accept any ESA letter a tenant hands me?
Not automatically. Under AB 468 (Health & Safety Code sections 122317-122319.5), a valid ESA letter must come from a licensed practitioner who conducted a clinical evaluation and had a client-provider relationship of at least 30 days. You may ask for documentation that meets these standards if the letter appears to be from an instant online mill.
What can I ask a tenant with a service dog?
If the disability and the animal's need are not obvious, you may ask only two questions: whether the animal is required because of a disability, and what task it is trained to perform. You cannot require certification, registration, an ID card, or a task demonstration.
Can I refuse an assistance animal based on its breed or size?
No. Breed, size, and weight restrictions do not apply to service animals or ESAs. You may deny a specific animal only if it poses a direct threat or would cause substantial property damage based on that animal's actual behavior, not its breed.
How much security deposit can I collect in California?
Under Civil Code 1950.5, amended by AB 12 effective July 1, 2024, most landlords are capped at one month's rent total. A small owner with no more than two properties and four units may collect up to two months' rent, but military service members are always capped at one month. Any pet deposit counts toward that cap.
Are ordinary pets treated the same as assistance animals?
No. For ordinary pets you keep normal discretion: you can adopt a no-pet policy, restrict breeds, and charge pet rent, subject only to the overall deposit cap. Those rules do not apply to genuine service animals or ESAs, which must be accommodated.
