Who may be liable
The upstairs neighbor is not the only party who may be liable. It depends on the cause and the area of responsibility.
- a neighbor — if the source is inside their apartment;
- the management company, homeowners' association or housing construction cooperative — if the cause relates to common property or inadequate building maintenance;
- a contractor — if the flooding relates to repairs or other work;
- the developer — if a construction defect is identified during the warranty period;
- several parties — if the causes and responsibility are shared.
