My question involves landlord-tenant law in the State of: California
I called my ex-landlord and gave her an oral 30-day notice on May 24th, which was agreed upon. I followed up with a letter dated May 24th and postmarked May 26th as a courtesy. I vacated unit on June 23rd, within full 30 days notice.
Now the ex-landlord is trying to extort additional rent from me, claiming I owe her rent through June 26th because the letter was postmarked on May 26th. Can she blatantly ignore the oral 30-day notice on May 24th (which I have a record on my cell phone statement)?
Doesn't the 30-day start from the date i.e. May 24th when I spoke to her on the phone and gave her an oral notice?
