Whether you can keep a pet in your New York apartment depends first on where the building sits. Inside the five boroughs, New York apartment pet laws give tenants a powerful protection: a landlord who knows about your pet and does nothing for three months loses the right to enforce a no-pet clause. Outside New York City, there is no equivalent state rule, and your lease controls almost everything. Federal disability law sits on top of both, requiring landlords anywhere in the state to accommodate service animals and emotional support animals regardless of what the lease says.
The NYC Three-Month Waiver Rule
New York City’s Administrative Code contains a tenant protection that exists nowhere else in the state. If a tenant in a building with three or more apartments keeps a pet openly for at least three months, and the landlord knows about it or should have known, the no-pet clause in the lease is treated as permanently waived for that animal.1New York City Administrative Code. New York City Administrative Code 27-2009.1 – Rights and Responsibilities of Owners and Tenants in Relation to Pets
“Openly and notoriously” is the operative phrase. Hiding the animal when the super comes by defeats the protection. Walking the dog through the lobby, taking it in the elevator, and letting building staff see it are what the rule contemplates.
The waiver covers renters in multifamily buildings and cooperative apartment owners across all five boroughs. Condominium owners are covered in Brooklyn, Queens, and Staten Island, but not in Manhattan or the Bronx. NYCHA properties are excluded and run their own pet policy: one dog expected to weigh under 25 pounds at full growth, one cat, or small caged animals like birds, fish, and guinea pigs.
One important limit: the waiver only blocks the no-pet lease clause. A landlord can still move to evict if the animal violates health codes, the Multiple Dwelling Law, or creates a genuine nuisance, even after the three months have run.
Pet Rules Outside New York City
Tenants in the rest of the state have no equivalent statute. No New York law forces a landlord to allow pets, and no waiver period kicks in with time. Your lease governs. If it says no pets, that clause is enforceable from the day you sign. If it is silent, you have a stronger argument that pets are permitted, but the landlord can add restrictions at renewal.
The state Multiple Dwelling Law does prohibit keeping farm animals such as chickens, goats, and swine in apartment buildings in any municipality that has adopted the law.2New York City Government. New York State Multiple Dwelling Law Beyond that, everything else is private contract. Read the lease before signing, and if a landlord tells you verbally that a dog is fine, get it in writing.
Service Animals and Emotional Support Animals
Federal law overrides no-pet clauses, breed restrictions, weight limits, and pet fees when the animal is an assistance animal for a person with a disability. Under the Fair Housing Act, landlords must make reasonable accommodations for both service animals trained to perform disability-related tasks and emotional support animals that alleviate the effects of a disability. This applies to every rental property in New York, including no-pet buildings, NYCHA housing, and buildings outside New York City.3U.S. Department of Housing and Urban Development (HUD). Assistance Animals
Under the ADA, a service animal is a dog individually trained to perform tasks related to a person’s disability, such as guiding someone who is blind or alerting someone who is deaf.4U.S. Department of Justice. ADA Requirements: Service Animals A dog whose only function is providing comfort does not qualify as a service animal under the ADA.5U.S. Department of Justice. Service Animals Emotional support animals do not need task-specific training; they qualify under the Fair Housing Act as long as a healthcare professional confirms the tenant has a disability-related need for the animal.
What a Landlord Can Ask For
When the disability or the animal’s role is not obvious, a landlord may ask for reliable documentation. A note from a healthcare provider with personal knowledge of the tenant’s condition, confirming both the disability and the therapeutic need for the animal, is the form HUD recognizes.6Department of Housing and Urban Development. Fact Sheet on HUD Assistance Animals Notice It does not have to come from a physician. A therapist, social worker, or other licensed provider can write it.7NY.Gov. Questions and Answers on Fair Housing Laws and Assistance Animals
Landlords cannot demand a diagnosis, require certification or registration of the animal, or rely on online ESA registries. HUD has said outright that documentation purchased from those websites is not reliable evidence.6Department of Housing and Urban Development. Fact Sheet on HUD Assistance Animals Notice Landlords also cannot charge pet deposits or pet fees for assistance animals, though tenants remain responsible for damage the animal causes.3U.S. Department of Housing and Urban Development (HUD). Assistance Animals
When a Landlord Can Say No
Denial is allowed only in narrow circumstances: the specific animal poses a direct threat to health or safety that no other accommodation can reduce, it would cause significant property damage that cannot be mitigated, or the accommodation would impose an undue financial burden on the landlord. Breed, size, and weight limits do not apply to assistance animals.3U.S. Department of Housing and Urban Development (HUD). Assistance Animals
Deposits, Pet Rent, and Fees
New York’s General Obligations Law caps the total security deposit for any residential lease at one month’s rent. The cap is absolute. A landlord cannot collect a separate “pet deposit” on top of it, and the label doesn’t matter: the statute covers any deposit or advance under any name.8New York State Senate. New York General Obligations Law 7-108 – Deposits Made by Tenants of Non-Rent Stabilized Dwelling Units
Monthly pet rent is different. Because it’s structured as recurring rent rather than a deposit, it sits outside the one-month cap. It has to be written into the lease to be enforceable; a landlord cannot add it mid-lease. And unlike the security deposit, which is refundable minus documented damages, pet rent is gone once paid.
A landlord who collects more than one month in deposits, whatever they call the extra, is violating state law, and the tenant can demand the excess back.9New York State Attorney General. Residential Tenants Rights Guide
Breed and Size Restrictions in Leases
Weight caps and breed restrictions in leases are generally enforceable as written. Caps often fall between 20 and 50 pounds, and breeds like pit bulls, rottweilers, and German shepherds are commonly named. If your lease has these clauses, violating them gives the landlord grounds to act even if the animal has never caused a problem.
There’s a twist that surprises many tenants. New York’s Agriculture and Markets Law bars local governments from regulating dogs “in a manner that is specific as to breed.” Your city or town cannot ban pit bulls or any other breed by ordinance, and the rule applies statewide, including New York City. But the prohibition targets government regulations, not private contracts. Landlords remain free to write breed restrictions into leases.
NYCHA has its own banned-breed list and a 25-pound weight limit for dogs. Tenants who registered dogs before the limit dropped from 40 pounds to 25 pounds in 2009 are grandfathered in, but new registrations must comply. Only a NYCHA hearing officer or a judge can order removal of a dog for violating the rule.
Dog Licensing
Every dog in New York State must be licensed once it reaches four months old, under the Agriculture and Markets Law. This applies whether you live in Manhattan or a rural town upstate. You apply through your local municipality, renew at least annually, and must show a current rabies vaccination.10New York State Senate. New York Agriculture and Markets Law 109 – Licensing of Dogs Required; Rabies Vaccination Required
Fees are set locally and are typically lower for spayed or neutered dogs. Licensing is not optional, and failing to license can result in fines. Licenses are not transferable; a new owner has to apply for a new one.
What Eviction for a Pet Violation Looks Like
A landlord cannot change the locks because of an unauthorized pet. The process is formal: a written notice to cure identifying the lease violation and giving time to fix it, then a notice of termination if the tenant doesn’t comply, then an eviction proceeding filed in court.
Even after a court finds the tenant breached a no-pet clause, the tenant gets a statutory lifeline. Under the Real Property Actions and Proceedings Law, the court must grant a 30-day stay before issuing a warrant of eviction, during which the tenant can correct the breach.11New York State Senate. New York Real Property Actions and Proceedings Law 753 – Stay in Premises Occupied for Dwelling Purposes For a pet violation, correcting it usually means removing the animal.
In New York City, the three-month waiver adds another layer. If the landlord knew about the pet for more than three months without filing suit, the no-pet clause is waived and eviction on that ground will fail.1New York City Administrative Code. New York City Administrative Code 27-2009.1 – Rights and Responsibilities of Owners and Tenants in Relation to Pets Outside the city, there is no such backstop, and a notice to cure should be taken seriously the day it arrives.
Liability and Insurance for Pet Owners
Pet owners bear primary responsibility when their animal injures someone, and lease indemnification clauses often require the tenant to cover legal costs and damages arising from incidents involving the pet. Those clauses are enforceable when clearly written. If your lease has one, expect the building’s insurer to seek reimbursement from you if a claim is filed.
Renters’ insurance is its own puzzle. Some policies exclude dog bites entirely, and others exclude specific breeds. If a landlord requires renters’ insurance as a condition of keeping a pet, confirm the policy actually covers your animal before you rely on it. A bill introduced in the 2025-2026 legislative session would prohibit insurers from refusing, canceling, or repricing homeowners’ and renters’ policies based solely on a dog’s breed.12New York State Senate. NY State Assembly Bill 2025-A10272 As of early 2026, the bill remains in committee. Until it passes, breed can still factor into coverage decisions in New York.
