Roomate Issues

[Joe Camarillo]

Hi everyone, a friend of mine is currently having an issue with a roomate and I was attempting to give them some advice. Im wondering have others handled this situations as landlords, or while being in a similar situation. I currently have a 2 bedroom apartment, and they have been renting out a room to a friend on a month to month basis, and recently they have brought in a pet that breaches the lease contract with the apartment complex. My friend is the only one currently on the lease. They have been trying to get them to remove the animal through a more civil manner, but I was wondering if they do not ultimately comply with removing the animal, could they possibly evict him, and if so, what routes would you guys take in issuing a notice of compliance, etc.?

Thank you 

Matt
