My question involves landlord-tenant law in the State of: California
I have a duplex and the back tenant signed a lease with he and his wife and 2 older sons living in it. His older son in his 30's took up living in the garage because it gave him more independence. He moved out a few months ago.
Now that he is no longer living there, I think this will give me a new opportunity to tell my tenant that we need to make up a new lease that is month to month.
My new tenants that live in the front house told me that they think someone new is living in the garage. In the past 4 other tenants knew this and got along fine with the back tenants. My new tenant who I am now seeing red flags of being a difficult person who doesn't get along with other people, is saying that there is body odor coming from the garage and she feels like she can't stand going into her garage because of it. She told me that I can be fined for allowing someone to live in the garage. I need to do my research but I know that my long staying tenant will say to me that since his son left they need additional income and renting out the garage which I will have to explain to him is breaking the contract if there is indeed a new person living in the house/garage/unit.
What if he denies that anyone is living there? I am sure that if I request to look in the garage I first have to give them notice and by the time I give that to them they will clean up the area so there is no evidence
If there is a new person living there, yes they broke the lease but I do not want to loose them as tenants. As far as I see they are good tenants that pay rent on time for the last 5 years and will give them an opportunity to sign a new month to month lease.
Any advice would be appreciated.
