Can I take posetion of my apartment after month by month expires

Hello l:

A month to month agreement expires every month. If you want to take possession, you're going to have to give your tenants at LEAST 30 days written notice to vacate.

Agreed, month to month requires a month's notice by LL or by tenant. If no 30 day notice is given by either side the "lease" renews for another month.
