Emotional Support animals

[Sean McNealley]

Hi there, first post on BP but figured this would be a good place to get some advice. 

I have had a tenant for roughly a year now, and we do not allow pets (unless they were there when we purchased the property) she hasnt had an animal for the last year. She all of the sudden needs an emotional support animal. My fear is that every tenant in my 6 unit will get upset and say its not fair etc. Has anyone had any experience with how to address this issue? Any advice would be appreciated, thank you
