I live in California and I'm on a month to month lease with 3 other roommates. About 2 months ago we found out that our landlord is planning on selling our house. After much consideration, I decided to ask my girlfriend to move in with me at another place. We only looked at two places, and applied to one, and I didn't get the time to tell my roommates I was considering moving out, when I found out today that we got the place (we only sent the applications in Monday)
So, now I have two weeks until I move into the new place (Aug 1st), and I'm curious about the law surrounding it. Can I legally give my roommates two weeks notice in California and move out before the next months rent is due, or do I have to give them a 30 days notice, and pay them a prorated amount for the rent through the 19th? Also, since it's a month to month, and my roommates would be picking up my part of the rent, do I legally have to tell my landlord that I'm moving out with a 30 day notice, or could I send her certified mail telling her what day I'll be moved out (August 1st or 2nd? Our rent is due on the 3rd of every month)
Another question, since I'm moving out now, can I legally ask my roommates for my portion of the deposit, or will I have to ask the landlord (who doesn't speak any English) for my portion of the deposit?
Thank you for any help you can provide.
