Custom-printed decals that tell customers exactly who's welcome through your door
Short answer: Yes, businesses can generally display a "Service Animals Only" decal to communicate that pets are not permitted while service animals are welcome. However, the wording and enforcement of the policy must be consistent with the Americans with Disabilities Act (ADA), which protects access for individuals with disabilities who use qualifying service animals.
These decals are commonly displayed on storefront doors, entrance windows, and other visible locations to help communicate a business's animal-access policy before customers enter. Understanding what the ADA allows, how service animals differ from pets and emotional support animals, and what information a decal should communicate can help businesses choose appropriate wording while respecting service animal access rights.
