Lease landed for a top-floor one-bedroom in Maspeth and the rider says tenants can’t install window ACs, only use the landlord’s through-wall sleeve unit for an additional monthly charge. The super already showed me the sleeve in the wall and said it’s easier for insurance. I own a window unit from my last apartment and planned to use it, but the lease specifically bans it. Is this common in NYC? Can they really stop me from putting my own unit in a window that opens onto the backyard? I don’t want to start a lease by fighting, but paying every month for an AC I didn’t pick feels wrong.
