Can a Roommate / Landlord Charge Rent After Giving Notice, Entering Room

[LosAngel]

My question involves a roommate in the State of: California

I am renting from this housemate under the false presumption that the apartment was to be shared equally, but this was revoked two months after moved-in when the housemate in anger stated I need to move out in 30 days (witnessed by the other renter). So immediately I called the property management company (partially to seek housing elsewhere), and it was at this point it has been discovered that the housemate had no rights to assign or sublet his rooms per his rental agreement with the property management.

I also caught housemate snooping in the room I am renting, and taking pictures. Door was originally closed when I stepped out into the kitchen. He harassed me asking questions "are you moving out?" of the sort. I declined to answer and instead asked him why he was in the room (invasion of privacy), and what the pictures were for. His response: "for future damages". He did not have reason nor did he provide a 24 hour notice to enter room.

15 days after the verbal notice, housemate gave a written 30 day notice. However, I am already moving out and do not believe housemate has the right to collect rent based on said verbal notice, and breaking the laws (entering room)?

I need some assistance and solid information in backing up my case if he does choose to pursue civil court against the other renter and myself (we share the same room), as his written notice used heavy legal terminology (assumed copied and pasted from the internet), claiming retaining of security deposit (which was never asked or given), and negative reports on our credit (housemate does not have that kind of information neither).

You owe rent through the end of your tenancy.

Your roommate's entry into your room does not mean you don't owe rent.
