If the person has been paying you rent, then give them a 30-Day Notice of Termination. If they have not been paying you rent (or some other type of consideration, such as buying groceries or paying the utilities), then they are a "tenant at will." Serve them with a 5-Day Demand for Possession. If they do not leave, then on the sixth day file an eviction action.
