The ADA and animals in public
The law
The statute people cite at the wrong moment, and the one that now shapes housing enforcement as well.
What it covers
Title II covers state and local government services; Title III covers public accommodations, which is most businesses open to the public. Both require access for service animals, defined as dogs individually trained to do work or perform tasks for the benefit of a person with a disability, with a separate provision for individually trained miniature horses.
The work or task has to be related to the disability, and the definition expressly excludes animals whose sole function is to provide comfort or emotional support. An emotional support animal has no public access rights under the ADA, and no letter changes that.
The two questions
Where it is not obvious what a dog does, staff may ask only two things: whether the dog is required because of a disability, and what work or task it has been trained to perform. They may not ask about the disability, demand documentation, require the animal to demonstrate the task, or charge a surcharge.
When a business may exclude
- The animal is out of control and the handler does not take effective action.
- The animal is not housebroken.
- The animal poses a direct threat, assessed individually rather than by breed.
Why this now matters in housing
Because HUD adopted the ADA training test for its own housing enforcement in May 2026. The line between a trained service animal and an untrained emotional support animal used to separate public access from housing. It now runs through housing too, which makes getting the characterisation right worth more than it used to be.
Common questions
- Can a business ask for papers?
- No. There is no documentation requirement and no register, and asking for papers is itself a common ADA mistake by businesses.
- Are psychiatric service dogs covered?
- Yes, where individually trained to perform a task. The task is what distinguishes them from an emotional support animal.
