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.
It really depends on where you live and if the landlord lives in the same housebut: are there clearly written rules in the lease about the windows needing to stay closed? If not it is likely not justifiable for them to close them. Typically a landlord needs to provide 24-48 hours notice to enter the unit so if they are showing up on random days and entering that it likely illegal. Throwing away personal property is also illegal. The security cameras could also be illegal. The only way to know any of this would be to contact a local housing justice non profit (if it exists) or preferably a local tenant lawyer. You need to make sure you are documenting everything that seems like a violation, even just writing a note of when and what happened but photos and video could be preferable
