I own a condo, and for 3 years had nothing but problems from the tenant upstairs, mostly extreme noise issues when he would have 20 people there all night being as obnoxious as possible. The tenant was a friend of the owner, who exhibited worse behaviour when he lived there. The strata finally had the tenant evicted, but he and his friends continue to show up in the suite (which is now vacant, and the owner lives in another suite in the building), and the behaviour continues. Can he and his friends be banned from the building if their purpose in going there is to be disruptive? If the owner argues that he has a right to allow whoever he wants on his strata lot, can the ex tenant not be prohibited from using common property, such as the lobby, elevator, hallway and walkways?
