I just got off the phone with Airbnb and for emotional support animals it seems that it works like this. If the person books an entire place or studio they do not have to disclose they have an emotional support pet. But if the place says no pets and it is not an entire unit or studio they have some say over emotional support pets.
If the place is listed as entire unit, is an apartment or studio they have no say in the emotional support pet being there, and do NOT have to disclose about the emotional support pet prior as that leads to judgement for disability. Many hate on emotional support pets on Reddit. I understand there are people who take advantage but there are definitely people who don’t.
In NY and California you cannot charge over an emotional support pets but in other states you might to a certain extent. If emotional support pets are renting entire unit again, they are allowed to be there and the pet DOES NOT have to be disclosed prior.
