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.
Probably not criminal trespassing, since they are the owner of the property. It may fall under tenant harassment, unauthorized entry, constructive eviction, or other laws that pertain specifically to landlord/tenant relations.
Check to see if there are any local tenant’s rights or advocacy groups in your area that offer free legal consultations. They’d be able to advise you on the local tenant’s rights laws and whether they apply to your situation.
