I want to keep my window open because it’s my preference. My landlord wants to keep it closed because they remotely controls the house’s A/C. They’ll walk right up to my room and slam it shut whenever they visits on random days to harass us about the kitchen looking like people live here.
I would guess that it isn’t trespassing in the normal sense since they own the house/building. Since the contract sounds like it allows them access inside and outside based on the kitchen stuff. Still would be good to see what legal protections you have for privacy as a renter in your area. If they are closing the window from the outside, it might not be legally trespassing (again in the normal sense of the law) as they could argue it is a facilities issue or something.
