Had to do this once at my old apartment. Building next door had some kind of alarm that would beep for 10 minutes straight, stop, then do it again like an hour later. Over and over. Forever. Went on for months. Right outside my bedroom window.

After realizing no one else in either building was going to do something about it I taped a very large, very rude note on the front door of the building calling them out. It was gone within a couple days.

This is what happens when you provide no way for anyone to contact your building’s management.
