My question involves landlord-tenant law in the State of: California
I moved in with a friend into another friends home so the 3 of us all live in this home together. It was understood that the owner of the home would move out and get someone to rent his room. I have only lived there for 3 months and the landlord (who lives with us) is very violent and aggresive. he and my roommate have gotten into numerous physical fights (the landlord is a male the roommate is a female) These fights go on for hours at all hours of the night. I am terrified of this man and scared for my own safety and the safety of my dog when I am not home.
He was angry with my roommate and snapped on me and I immediatly grabbed a night bag and left. The next day I told him I can no longer live there. He says that since I am breaking the lease he is going to sue me for the rest of the years rent.
What are my rights in this situation? Can he sue me for breaking a lease under these circustances and if so will he win? I wanted to keep it short but I cant give more details if needed.
