A VvE (Vereniging van Eigenaars) is a mandatory association for all apartment owners within a building. When you buy an apartment, you automatically become a member. This is a legal requirement and you cannot opt out.
As a member, you share responsibility with other owners for the maintenance, costs and management of the building. This includes shared elements such as the roof, facade and common areas.
The VvE ensures that these parts are maintained and that decisions are made collectively.
