I've recently moved into a new (and rather expensive) condo. It's fine, except for the fact that the neighbours upstairs frequently soak my balcony with water. I know that part of the reason is that they're watering their plants (which causes a small amount of water to drip down), but just now it seems like they emptied a large bucket of water, and it soaked a lot of stuff on my balcony (and dripped down onto at least the one below me). My roommate has also said that they've poured water on him when he barbecues, and he's been forced to stop using the BBQ because of it (which is ridiculous). I mentioned it to the landlord, and he went to try to talk to them but nobody was home. I can't go up and do anything myself, because I don't have the permissions to get up there (everyone is issued a key fob that allows them to go to their floor, the garbage/storage rooms and to get into the front door - you can't go anywhere else).
