landlord rights during 30 day notice period
I rented a room in my home with use of a bathroom and kitchen to a couple of college students and their dog. It went wrong, very quickly. I gave them a notice to quit/vacate on 2/27 so that they must vacate by 3/31. In the interim, they are parking where I ask them not to, running a space heater that I forbid them to have in the house, blowing fuses from too many appliances, letting the dog jump on and scratch up the door, and defecate on the walkway, and refusing to allow me access to their space to show the room (even with notice) by putting signs up stating that they ”will not be home and if I enter they will consider it breaking and entering and contact police.” I feel intimidated and harassed in my own home and do not know where my rights begin and end. There was never anything in writing. What are my rights in terms of room access and enforcing things like parking and electric issues or the heater while I wait out the next 30 days?
