While the Americans with Disabilities Act applies to may situations and places you may go with your service dog, it doesn't apply everywhere. Go here to read about where the ADA does apply. But here are some other laws you should know about.
The Fair Housing Act Amendment (FHA)
the law that says landlords must make reasonable accommodations for tenants with disabilities. That means service dogs, emotional support animals (which don't
have to be dogs) and service dogs in training must be allowed in no pets
housing and that landlords can't charge any additional fees or deposit
for these animals. Some landlords are exempt from the FHA, though. For
instance, they have to have more than four rental units in order for
the FHA to apply. They can require you to provide documentation verifying you need a reasonable accommodation but it doesn't have to say what your disability is. If you feel you've been denied access or discriminated against under
this law, you can file a complaint with the U.S. Department of Housing and Urban Development (HUD).
Air Carriers Access Act (ACAA)
This is the law that says airlines flying within the US must make reasonable accommodations for customers with disabilities. This means they must allow service dogs and emotional support animals (which don't have to be dogs) to fly in the cabin of the plane and they cannot charge an additional fee for the animals. Airlines can require you to provide documentation if you want to fly with a psychiatric service dog or an emotional support animal, though. If you feel you've been denied access or discriminated against under
this law, you can file a complaint with the
U.S. Department of Transportation.
