Recently, my 1 year lease for a house ended, and I moved out at the end of the 12th month. I did not, however, give a 30 days notice, since I assumed it was implied since the lease was going to be up. The landlord is charging me for an extra months rent since I didn't give the notice. Is that legal? The landlord was planning on selling the house after my rent was up, and had several people come and look at the house while I was living there. I live in California by the way if that matters
