California 30 day notice requirements
I just moved out of a home and had a disagreement with the landlord. I gave a 30 notice on the 17th or last month. Since the month had 31 days, I took that to mean that my tenancy was over on the 17th of the next month. When I moved in, I was required to pay first month (prorated since he wanted me in ASAP and I moved in in the middle of the month), last month and 100% of the monthly cost for a deposit.
Since I just moved, I'm having a hard time finding my copy of the rental agreement. He's agreed to send me a copy because we're debating about whether I should be prorated for the half month I paid in advance and didn't use (due to giving my 30 day notice in the middle of the month). Under what circumstances will he be able to keep all of my last month's rent? Is there something specific I should look for in the rental agreement when I get a copy? Is there a specific law/code that references this?
Also, does anyone have a legal definition of "normal wear and tear," that has been uphold in courts? The wording it, unfortunately vague and I don't know what I'm liable for and what I'm not. There are some obvious things I have to pay for and won't dispute, but there are some things that I think are debatable.
