Hi BP Community, I need your input as to what to do in a situation I'm having with one of my tenants in California.   This particular tenant is a dog walker and had a pitbull that I discovered she was keeping in her home.  I gave her several warnings and eventually an evection notice last month.  Today she emails me and tells me that she has been seeing a therapist for anxiety and the therapist prescribed a emotional support animal animal or companion animal.  She also sent me a copy of the prescription from her therapist.    She said she did not realize that the dogs that she was walking helped her with her mental health, anxiety issues, until she was forced to stop her dog walking business.   So she started seeing a therapist and that is when the therapist prescribed her the service dog.   Seems like a deceitful way to get her pet in the house.  This tenant's lease ends In June and I was planning not to renew even before I found out about her service dog because  I've had a lot of issues with these tenants regarding, not only the dog, but also excessive noise (partying late nights). The tenants that lived below them moved out because of the noise they were causing.   How should I proceed in this situation since she only has a few months left in her lease. And if I don't renew her lease will she view it as retaliation?  Can I renew without giving a reason? Any advice would be appreciated.  Thanks
