My tenant in California, who has been on a month to month lease sine 5/2008, has violated the lease by having a fire in the yard, which is against the county ordinance. He has done this in the past, and I have given him warnings verbally and by email that he needs to stop. I think I am no longer required to give him 60 days notice to move, and can serve him a 3 day notice to move for violating the lease? Is this true even if I didn't give him a written warning to stop fires, (does email count as written?) If I want to give him extra time, say 30 days, how would i do that?
