What should I do if the external wall of my house leaks and the property management is not completely solved?

Second, the problem of water leakage on your roof: this is a project quality problem left over from history. Article 2 of the "National Measures for Quality Assurance of Construction Projects" stipulates: "The leakage prevention of roofing waterproof projects, toilets, rooms and external walls with waterproof requirements is 5 years"; It also stipulates that the maintenance fund shall be collected by the maintenance fund, and the maintenance cost without the maintenance fund shall be shared by the beneficiary owners. As far as I know, you didn't collect public maintenance funds when you handed over the house.

Article 54 of the Regulations on Property Management in Fujian Province: "When there are potential safety hazards in the property, which may endanger public interests or the legitimate rights and interests of others, the relevant owners shall timely repair and maintain it, and other owners shall cooperate. If the relevant owners fail to perform the maintenance obligations, the owners' committee may entrust the property management enterprise to maintain or take emergency preventive measures on their behalf upon the decision of the owners' meeting or directly in accordance with the agreement of the owners' convention, and the expenses shall be borne by the relevant owners. "You can refer to the" Measures for Quality Assurance of Housing Construction Projects "and the" Regulations on Property Management in Fujian Province "to see what kind of property you belong to.
