There is 2 different kind of category one is the service animal that they provide life saving chores from them like seen eye dog, detect seizure, assisting with MS and ECT..
The other kind is emotional support that they comfort them with anxiety and other emotional issues that someone might have and that could any kind of animal like dog, cat, snake, pig or whatever and they need that mostly when they fly or do thing that make them uncomfortable which living in the house shouldn't be one of them...
As a landlord you are allowed to ask for documentation and a kind of service that animal provide.
Most people or owner if they are not legit don't know the difference between service animal or emotional support so you need to ask them which one is it?
Ask for their document and you are allowed as a landlord. Make sure when you get that paper you verify the legitimacy of that paper since THEY COULD BE BOUGHT ONLINE for $60 or so... Those documents are good only for one year so every year they have to provide you with a renewed one.
If is a emotional support make sure call the Dr that signed that paper to verify they exist and verify their lic with the state make sure they are still active and working.
But for service animal you can ask what kind of service they provide and what are the signs and how they provide that service and of course you need to verify their doc same with the state cuz their paper is different.
You can always ck https://adata.org/publication/service-animals-booklet for any question you might have.
I hope this helped....
