Can You Sue Your Landlord If a Neighbor's Dog Bites You in NY?

Getting bitten by a dog that belongs to another tenant raises an immediate question. Who do you actually go after? The dog’s owner might not have much insurance or money.

Landlord liability for dog bites is often the more realistic path. This is especially true when the bite happened in a hallway, lobby, or shared yard.

This blog explains when a landlord can actually be held responsible. It covers what recently changed in New York law and what evidence helps support a claim.

1. Why This Question Comes Up So Often in Shared Buildings

Multi-family buildings create close contact between tenants and their neighbors’ pets. Lobbies, stairwells, mailrooms, and shared yards put people and dogs in the same space daily.

This proximity means landlord liability for dog bites comes up constantly in apartment and multi-family settings. A tenant bitten in a common area often has no relationship with the dog’s owner at all. Filing a claim against a stranger can feel far less realistic than looking to the building’s owner instead.

Our Dog Bite Accident practice page covers how our firm evaluates these cases. This includes situations involving multiple potentially responsible parties.

2. What Flanders v. Goodfellow Changed for Third Parties

For years, New York limited dog bite claims to strict liability alone. A victim had to prove the owner knew, or should have known, the dog was dangerous. Ordinary negligence claims were not allowed at all.

That changed in April 2025.

According to the New York Court of Appeals decision in Flanders v. Goodfellow, negligence is now a valid legal theory in dog bite cases. The court overruled decades of precedent. That precedent had blocked negligence claims for harm caused by domestic animals.

This matters for landlords specifically. The ruling opened the door to a new argument. A third party, not just the dog’s owner, can now be shown to have failed to exercise reasonable care. Landlord liability for dog bites became a more viable path once negligence claims were back on the table.

3. When a Landlord's Own Actions Create Liability

A landlord is not automatically responsible just because a tenant’s dog bit someone. Liability generally depends on what the landlord knew. It also depends on what they did, or failed to do, about it.

Several situations tend to support a claim:

The landlord received prior complaints about the dog’s aggressive behavior
The lease allowed the landlord to require a dog’s removal, and they chose not to enforce it
The landlord had control over common areas where the dog was allowed to roam freely
The landlord had actual knowledge of a prior bite or attack involving the same dog

According to New York Agriculture and Markets Law Section 123, an owner of a dog legally declared dangerous faces strict liability for medical costs. A landlord’s own liability works differently. It generally depends on negligence principles instead.

4. What You Need to Show the Landlord Knew

Building a claim against a landlord usually comes down to proving they had some level of awareness beforehand. Useful evidence includes:

Written complaints or emails sent to building management about the dog
Testimony from other tenants who witnessed prior aggressive behavior
Maintenance or incident logs mentioning the dog
Lease provisions addressing pet behavior or breed restrictions
Any prior 911 calls or animal control reports tied to the same dog

Without proof of prior knowledge, a claim against the landlord becomes much harder to support. This is why documentation matters so much.

5. Landlord Liability for Dog Bites vs. the Dog Owner's Liability

These are two separate claims that can sometimes be pursued together. The dog owner’s liability depends on strict liability or negligence tied directly to the animal. Landlord liability for dog bites depends instead on the landlord’s own knowledge and conduct.

Our earlier post, Who Is Legally Liable for a Dog Bite Injury in New York?, covers the dog owner side of this equation in more depth. This post focuses on when a landlord shares that responsibility instead.

A victim is not required to pick only one theory. Both the owner and the landlord can potentially be named in the same claim.

6. Evidence That Strengthens a Claim Against a Landlord

Landlord claims depend heavily on prior knowledge. The evidence gathered after a bite carries real weight. It helps to:

Photograph your injuries and the location where the bite occurred
Ask neighbors whether they ever complained about the dog
Request building maintenance or incident records through your attorney
Keep copies of your lease and any building pet policies
Report the bite to NYC Health and to building management in writing

Written communication with management creates a paper trail. This can support your claim later. A phone call alone is much harder to prove.

7. Frequently Asked Questions

Does it matter if the landlord lives in the building?

Not necessarily. What matters most is whether the landlord knew about the dog’s behavior and had some ability to act on it. Living on site is not the deciding factor.

What if my lease says pets are not allowed at all?

A no-pet clause can actually support a claim. It may show the landlord had grounds to have the dog removed. Failing to act on that authority strengthens the negligence argument.

Can I sue the landlord even if the dog owner has insurance?

Yes. A landlord’s potential liability is separate from the dog owner’s insurance coverage. Both can be pursued, depending on the facts.

Does this apply to a single-family rental too?

It can, though shared common areas make landlord knowledge easier to establish. A single-family rental generally requires more direct proof of what the landlord knew.

How long do I have to file a claim?

Personal injury claims in New York generally must be filed within three years of the bite. Acting sooner helps preserve evidence and witness memories while they are fresh.

8. Next Steps After a Dog Bite in Your Building

Landlord liability for dog bites often depends on evidence that can disappear quickly. This includes witness memories and informal complaints that were never written down. Acting early gives your claim a stronger foundation.

The 2025 Flanders v. Goodfellow decision opened the door to negligence claims against third parties, including landlords.
Prior complaints, lease terms, and maintenance records are often the strongest evidence of a landlord’s knowledge.
A landlord’s liability is a separate legal theory from the dog owner’s liability. Both can sometimes be pursued in the same claim.
Written documentation holds up far better than verbal reports. This includes emails and formal complaints proving what a landlord knew.
