I don't have an ESA so I can't say firsthand, but my understanding is that in California, the Disabled Persons Act has this effect. Intuitively, I think the idea is that when your doctor certifies that you need an ESA, the reason is that you have a disability, so a landlord rejecting it would be illegal discrimination. Edit: I believe this only applies to housing, not restaurants or other businesses.
