Legal analysis: Who will bear the maintenance cost of house leakage should be decided according to the actual situation. If the house leaks water, if the fault party can be determined, it will be compensated directly by the fault party. Housing maintenance fund, with the consent of more than 2/3 owners, can apply for the use of maintenance fund maintenance. If there is no maintenance fund, the relevant owners need to share the maintenance costs in proportion. However, in real life, many owners will shirk the leakage of their houses and refuse to bear the part of the expenses that should have been shared.

Legal basis: Article 280 of the Civil Code of People's Republic of China (PRC), the decisions of the owners' congress or owners' committee are legally binding on the owners.

If the decision made by the owners' congress or the owners' committee infringes on the legitimate rights and interests of the owners, the infringed owners may request the people's court to revoke it.
