My tenant's dog bit someone: is the landlord liable?

Who is liable for a dog bite

Dog-bite law differs a lot by state. Some states make the owner strictly liable for a bite, whether or not the dog had bitten before. Others follow the old rule that the owner is liable only if they knew the dog was dangerous, often called the one-bite rule, or use a negligence test. In most places the person liable is the dog's owner or keeper, which is the tenant, not the person who owns the building.

A landlord is more likely to face a claim when three facts line up: the landlord knew the dog was dangerous, the landlord controlled the place where the bite happened or could remove the dog under the lease, and the landlord took no reasonable step.

A few states and local laws widen who counts as a keeper. Ask a local attorney about your state.

What counts as knowing a dog is dangerous

• A prior bite or attack that someone reported to you.
• Written complaints from neighbors or tenants about aggression.
• A tenant telling you the dog has bitten before.
• A citation or order from animal control that you received.
• Your own observation of aggressive behavior on the property.

Know what the lease allows before a problem starts. A lease with a pet addendum usually lets you require a leash in common areas, limit the number of animals and ask for proof of vaccination. A lease that says nothing leaves you with fewer tools when a complaint comes in.

Knowledge is the heart of most landlord cases. A record of complaints you ignored is the opposite of what you want. A record of complaints you acted on, with dates, is what protects you.

What to do when you hear about an aggressive dog

1. Write down the complaint: who, when and what happened. Ask for it in writing.
2. Send the tenant a written notice that cites the lease's pet and nuisance terms and asks for a plan to keep people safe, such as a leash, a fence or training.
3. Check local rules. Animal control may require a dangerous dog to be confined or registered.
4. If the danger continues, follow your state's process to require removal of the animal or, as a last resort, to end the tenancy. Do this with a legal notice, not with a threat.
5. Keep a log of each step and each tenant response.

An assistance animal is not a pet under fair housing law, and a request for one needs its own process. An animal that poses a direct threat can still be dealt with, but the rules are specific. See the assistance animal guide.

Insurance and the lease

Dog bites account for a large share of liability claims under homeowners policies, according to the Insurance Information Institute, and some insurers limit or exclude cover for certain breeds or for any dog with a bite history. Landlord policies vary. Ask your agent whether your policy excludes any dogs or has a lower limit for animal injury.

• Require every tenant with a pet to sign a pet addendum that states the animal's details and the tenant's responsibility.
• Require a renters policy with liability cover that does not exclude the dog.
• Do not ban breeds in a way that violates fair housing or assistance animal rules. See the breed restriction guide.
• Report any bite on your property to your insurer promptly.

This is general information, not insurance or legal advice. Your policy wording, your state and your licensed agent or attorney decide what applies to you.

How DoorKeeping handles it

Each complaint and your notice to the tenant are saved with the lease through email to tenants, and a signed pet addendum is stored with it from your e-signed lease. A dated record of what you did, in one place, is what you need if a claim comes. DoorKeeping does not sell insurance or decide coverage.

Questions

Is a landlord responsible if a tenant's dog bites a guest?

Usually the tenant, as the owner, is. A landlord can be liable if they knew the dog was dangerous, had control to act and did not. The law differs by state.

Can I evict a tenant because their dog bit someone?

Possibly, if the lease and your state's law allow it, after proper written notice. Assistance animals have special rules, so ask a local attorney first.

Does landlord insurance cover dog bites?

Often it covers the landlord's own liability, but some policies exclude certain breeds or animals with a history. Confirm with your agent.
