Are emotional support animals different from pets?

The label matters, because each category carries different obligations. Mixing them up is how landlords end up in trouble.

• Pet: an animal kept for companionship that is fully subject to your lease, including pet rent, deposits, and breed or size limits.
• Emotional support animal: an assistance animal that eases symptoms of a disability through its presence. It needs no special training and is not a pet under fair housing law.
• Service animal: typically a dog individually trained to perform tasks for a person with a disability, covered by its own access rules.

An ESA qualifies through the tenant's disability and need, not through a vest, an ID card, or an online registry. None of those items prove anything on their own.

Once you have a valid ESA request, your ordinary pet rules step aside for that specific animal.

• No pet fee, pet rent, or pet deposit for the support animal.
• Your no-pets policy and any breed or weight restrictions do not apply to it.
• The tenant remains fully responsible for any damage or injury the animal causes.
• The animal must still not be a genuine nuisance or a documented threat to others.

In short, you waive the pet-related charges and limits, but you do not waive the tenant's duty to keep the property in good shape and the neighbors safe.

If the disability and the need are obvious, accept the request and move on. If they are not, you may ask for reliable documentation from a licensed health provider who actually knows the tenant. Keep your request narrow and respectful.

• Do ask for confirmation that a disability exists and that the animal helps with it.
• Do not demand the diagnosis, medical records, or the tenant's full history.
• Be wary of instant certificates sold online with no real provider relationship behind them.

What you may require, and how you may treat a questionable letter, differs by location. Some states regulate ESA documentation directly. Review the guides at /laws/ and check close calls with your own counsel.

An ESA request is not automatic approval. You may deny one when the specific animal poses a direct, documented threat that cannot be reduced. You may also refuse when accommodating the animal would impose an undue financial or administrative burden on you.

These exceptions are narrow and fact specific, so a blanket refusal is risky. Denial thresholds vary by state. Write down your reasoning, keep any supporting evidence, and get legal advice before you turn down a request that sits near the line.
