I live in Los Angeles California. I've lived in my apartment for over 1 year after signing a 12 month lease. Now that the 12 months on the lease are over, my landlord wants me to sign a new 12 month lease.

I don't want to sign another 12 month lease. I may go to school in a few months and I'd like to go month to month. I know she can raise the rent, but I'll accept that for the flexibility of leaving when I need to without breaking a lease.

But my landlord says I have to sign a new lease or she'll kick me out. She says I I live there "at her discretion". Is it legal for her to make me sign another 12 month lease, or can I tell her she can't make me, and go month to month?
