I live in a house. I live on the ground floor and have private/exclusive access to the back yard. My landlord recently made sure to add it to my new updated lease. The guy upstairs is an entitled jerk. I’ve had to call the cops on him for noise. He fights with his gf. He tried to beat in my doors when I filed a noise complaint. I put in ring cams because I couldn’t put a restraining order on him without the videos of him trying to break in. For the past 4 years he’s come into the back yard to spray down rugs that his dog pees on. Frequently, I have my back door/screen door open and I am in various forms of undress. A few weeks ago I was in my towel and he walks back there and starts spraying down his piss rugs. For context, the hose is directly outside the window and door. I told my landlord he needed to tell him to stop on Tuesday. Today, the ring cam dinged him doing it again. I sent the video to the landlord. What do I do next? My sister suggested locking the gate around the house to the back but then the garbage and recycling bins will end up outside my front window. Something I also don’t want. A friend suggested putting up a no trespassing sign, and then calling the police. I’d prefer to TRY to be amicable. I don’t even know at this point if my landlord talked to him yet. What do I do?
