When it comes to allowing or restricting service animals in your business, it is important to understand your rights and obligations under the Americans with Disabilities Act (ADA). Doing so will help your business accommodate customers with disabilities while avoiding disputes and liability.

This article breaks down the ADA regulations pertaining to service animals in business settings, so you can remain compliant and avoid a lawsuit.

What is a Service Animal?

Under the ADA, a service animal is generally defined as a dog of any breed or size that has been trained to perform work or tasks for a person with a disability. Service animals are working animals – not pets. The work or task performed by the dog must be directly related to the person’s disability. Examples of service animal tasks include:

• Guiding individuals who are blind or have low vision
• Alerting individuals who are deaf or hard of hearing
• Pulling a wheelchair
• Assisting during a seizure
• Retrieving items

 
Emotional support or therapy animals are not considered service animals under the ADA. A common misconception that gets businesses in trouble is that service animals must be clearly identified. The ADA does not require that service animals wear a vest, ID tag, or harness.

Which Businesses Must Comply?

For private businesses, service animals are covered under Title III (public accommodations and commercial facilities) of the ADA. This means that all private businesses and nonprofit organizations that serve the public must comply with ADA service animal requirements. This includes restaurants, retail stores, hotels, service providers, and many other establishments that qualify as places of public accommodation.

Businesses covered under Title III are expected to make “reasonable modifications in policies, practices, or procedures,” to accommodate individuals with disabilities, including allowing service animals into their business. For example, a business with a “no pets” policy is generally required to make an exception for service animals.

What Businesses Can and Cannot Ask?

When it is not clear that an animal is a service animal, the only business owners can ask customers with an animal are:

1. Is the dog a service animal required because of a disability?
2. What work or task has the dog been trained to perform?

 
The ADA also places clear limits on what business owners and employees may ask or require. Specifically, businesses may not:

• Require certification, identification cards, proof of training, or other documentation for a service animal;
• Ask about a person’s disability;
• Require the dog to demonstrate its trained task or ability; or
• Require individuals with service animals to sit in a designated section.

 
When Can a Service Animal be Removed?

The ADA recognizes three situations where a business may deny access to an individual with a service animal or ask that the service animal be removed. The three exceptions are:

• The animal is out of control and the handler does not take effective action to control it,
• The animal is not housebroken, or
• Making the required modification to policies, practices, or procedures to accommodate a service animal would “fundamentally alter” the nature of the goods, services, programs, or activities provided by the entity to the public.
  • This is a very narrow exception and, in most cases, businesses can provide accommodations without fundamentally altering the goods or services provided. One example would be parts of a zoo where the displayed animals are prey or predators of dogs, and the presence of a service animal could cause the displayed animals to become agitated.

 
If a service animal is excluded on these grounds, the business should still offer the individual the opportunity to obtain goods or services without the animal present.

Common Questions:

• Can businesses charge pet fees?

No, the ADA does not permit businesses to charge owners for having their service animal in a facility unless the animal causes damage.

• Are emotional support animals treated the same as service animals under the ADA?

No, the ADA only protects task-trained service animals, not emotional support animals. However, because of the two-question rule and the prohibition on asking for training verification, it may be difficult for a business owner to confirm that an animal is a trained service animal. Even if a business owner suspects a customer is lying about the status of an animal, the business should err on the side of caution and allow the animal.

• If a staff member is allergic or scared of dogs, can the business deny entry?

No, businesses with employees who are allergic or fearful of dogs must still allow service animals into public areas.

• Are there health or safety exceptions?

Not necessarily; establishments that prepare or serve food must permit service animals in public areas, even when state or local health regulations prohibit pets.

• Are employees permitted to bring a service animal to work?

An employee’s request to bring a service animal to work should be evaluated as a potential reasonable accommodation under Title I of the ADA.

Good Practices for Businesses

A few proactive steps can help businesses avoid misunderstandings and reduce legal risk:

• Train employees on the ADA’s two-question rule and ensure staff understand that service animals should not be treated the same as pets.
• Focus on the animal’s behavior rather than the person’s disability.
• Document incidents involving disruptive or out-of-control animals.
• When removing a service animal becomes necessary, explain the reason clearly and professionally.
