Under the Americans with Disabilities Act (28 CFR § 36.302(c)(6)), staff at a business or other public accommodation may ask only two questions when it is not obvious that a dog is a service animal: (1) Is the dog a service animal required because of a disability? (2) What work or task has the dog been trained to perform? They may not ask about your disability, demand medical documentation, require certification or registration paperwork, or insist the dog demonstrate a task.
The two-questions rule is the single most important piece of public-access law for handlers to memorize. It limits what staff can ask, and it’s the line a manager crosses when they push for more. Knowing the rule cold lets you answer cleanly, walk in, and move on with your day instead of getting tangled in a conversation that has no legal basis.
This guide walks through the exact wording of the rule, what counts as a legal question vs. an illegal one, what to do when staff cross the line, and how the rule applies to specific settings like restaurants, hotels, hospitals, and grocery stores.
What does the ADA two-questions rule actually say?
The Department of Justice’s regulation at 28 CFR § 36.302(c)(6) governs public accommodations under Title III of the ADA. The exact text is short:
“A public accommodation shall not ask about the nature or extent of a person’s disability, but may make two inquiries to determine whether an animal qualifies as a service animal. A public accommodation may ask if the animal is required because of a disability and what work or task the animal has been trained to perform. A public accommodation shall not require documentation, such as proof that the animal has been certified, trained, or licensed as a service animal.”
Three things matter in that paragraph. First, the rule applies only when the dog’s role is not obvious. A dog actively pulling a wheelchair or guiding a blind handler is obvious — staff don’t get to ask anything. Second, both questions are about the dog, not the person. Third, the rule explicitly bars demands for documentation. There is no certificate, no card, no registration database that staff can lawfully require.
What are staff allowed to ask, word for word?
Any phrasing that boils down to these two ideas is fair game:
- Question 1 — Necessity: “Is the dog a service animal required because of a disability?” Variations like “Is that a service dog?” or “Is your dog a service animal?” are all legal.
- Question 2 — Task: “What work or task has the dog been trained to perform?” Variations like “What does your dog do for you?” or “What is your dog trained to do?” are legal.
Your answer to question one is yes. Your answer to question two should be a short, concrete task: “He alerts me to changes in blood sugar,” “She interrupts panic attacks,” “He retrieves dropped items because I use a wheelchair,” or “She guides me because I’m visually impaired.” You do not have to name your disability. You do not have to elaborate.
What are staff NOT allowed to ask or demand?
The DOJ has been explicit about what crosses the line. Staff cannot:
- Ask about the nature or severity of your disability.
- Require medical documentation, a doctor’s note, or any letter.
- Require a service-dog ID card, vest, harness, certificate, or registration paperwork.
- Require the dog to demonstrate the task it’s trained to perform.
- Charge a pet fee, deposit, or surcharge for the dog (cleaning fees for actual damage are still allowed).
- Refuse entry because of breed, size, or fear of allergies in other patrons.
- Require advance notice that you’ll be bringing a service dog.
The DOJ’s ADA Requirements: Service Animals guidance and the Frequently Asked Questions about Service Animals and the ADA document spell each of these out. They are the primary source any business can be referred to.
| Question or Demand | Legal under ADA? | Why |
|---|---|---|
| “Is that a service dog?” | Yes | Restates question 1 |
| “What is your dog trained to do?” | Yes | Restates question 2 |
| “What’s your disability?” | No | Bars inquiry into disability nature |
| “Show me your paperwork.” | No | ADA forbids documentation requirement |
| “Can you make him do the task?” | No | ADA forbids forced demonstration |
| “We charge $50 for pets.” | No | Pet fees barred for service dogs |
| “We don’t allow that breed.” | No | Breed bans cannot exclude a service dog |
What if staff ask an illegal question or refuse entry?
Stay calm and stay short. A clean script handles most cases:
“Under the ADA, you can ask me two questions: whether my dog is required because of a disability, and what task he’s trained to perform. The answer to the first is yes. He’s trained to [task]. I’m not required to provide documentation or have him demonstrate.”
If staff still refuse entry or escalate, ask for a manager. If the manager refuses, you have three escalation paths:
- File an ADA complaint with the U.S. Department of Justice at ada.gov. Complaints can be filed online and trigger a DOJ review.
- File a complaint with your state attorney general’s civil-rights division. Most states accept ADA-related public-accommodation complaints.
- Consult a disability-rights attorney. Title III of the ADA allows private lawsuits for injunctive relief and, in some states, damages.
Document everything: date, time, location, names of staff, what was said. Keeping a short note on your phone immediately after the incident makes any later complaint far stronger.
Does the rule apply differently in restaurants, hotels, and hospitals?
The rule itself is the same in every Title III public accommodation, but a few setting-specific notes matter:
- Restaurants: Service dogs are allowed in dining rooms, even where state health codes ban pets. Food-prep areas (kitchens) can lawfully exclude any animal, including service dogs.
- Hotels: No pet fees, no pet deposits, no “designated pet rooms.” The hotel cannot restrict you to a smoking floor or a back-of-house room.
- Hospitals: Service dogs go where the public goes — lobbies, exam rooms, patient rooms. They can lawfully be excluded from sterile environments like operating rooms and burn units.
- Grocery stores and pharmacies: Full access. The Food Code’s animal ban explicitly carves out service animals.
- Schools and government buildings: Title II of the ADA covers these (28 CFR § 35.136), with substantively the same two-questions rule.
Why did the DOJ adopt the two-questions rule?
The 2010 ADA amendments tightened the definition of “service animal” and limited businesses’ ability to interrogate handlers. The DOJ’s stated reasoning was twofold: protect handler privacy (asking about disability is invasive) and prevent businesses from using paperwork demands as a backdoor exclusion. There is no federal service-dog registry the DOJ could point staff toward, so requiring documentation would have meant requiring something that does not exist. The two-questions rule resolves both problems by limiting inquiry to the dog’s role.
The rule has held up in court. Courts have consistently rejected business-side arguments that they should be able to ask more, citing the DOJ’s clear regulatory text and Title III’s broad protection of disabled people from access discrimination.
Do I need to carry an ID card or letter to answer the two questions?
No. The ADA does not require any documentation, and the rule explicitly forbids businesses from demanding it. That said, many handlers carry a USAR digital ID, an Apple Wallet pass, or a printed ID card voluntarily because it shortens interactions. A staff member who’s about to ask a third or fourth illegal question often de-escalates the moment they see something on a phone screen — even though they can’t legally require it. The card doesn’t grant any rights you don’t already have under federal law; it just makes day-to-day access friction lower.
If you carry credentials, make sure your phone shows the dog’s role and a verification link to a registry that publishes the record (USAR’s verification page lives at /verify/). That’s the practical shortcut. Don’t hand over a paper letter from your doctor — that would over-disclose your disability and is never required.

Common questions about ada two questions rule
What are the two questions a business can ask about my service dog?
Under 28 CFR § 36.302(c)(6), staff may ask: (1) Is the dog a service animal required because of a disability? (2) What work or task has the dog been trained to perform? They may not ask about your disability or demand documentation.
Can a business demand a service dog ID card or certificate?
No. The ADA explicitly forbids requiring documentation, registration paperwork, or proof of certification. Many handlers carry an ID card voluntarily for convenience, but no federal law allows a business to demand one.
Do I have to demonstrate my service dog's task?
No. The DOJ’s regulation prohibits requiring a service dog to demonstrate the task it’s trained to perform. You only need to verbally name the task in response to question two.
What if staff ask about my disability?
That question is not allowed. You can decline to answer and remind staff that the ADA limits inquiry to whether the dog is required and what task it performs. If they refuse access after that, ask for a manager and document the incident.
Can a restaurant charge me a pet fee for my service dog?
No. The ADA prohibits pet fees, deposits, or surcharges for service dogs. The business may still charge for actual property damage if the dog causes any, applied the same way it would for any guest.
What if my service dog's role is obvious — do staff still get to ask?
No. The two-questions rule applies only when the dog’s role is not readily apparent. A dog actively guiding a blind handler, pulling a wheelchair, or alerting to a seizure is obvious and staff cannot ask any clarifying questions.
Where do I file a complaint if a business refuses entry?
File an ADA complaint with the U.S. Department of Justice at ada.gov. You can also complain to your state attorney general’s civil-rights division and consult a disability-rights attorney about Title III enforcement.
Does the rule apply to hotels and Airbnb-style rentals?
Hotels are public accommodations covered fully. Pet fees and deposits are barred. Owner-occupied short-term rentals with fewer than five units may fall outside Title III; the Fair Housing Act may still apply for longer-term stays.
