Should the property be responsible for the water leakage on the windowsill?

Legal analysis: it is the responsibility of the developer that the owner's window leaks rain.

After the delivery of the house, if it is not caused by human factors, then all responsibilities shall be borne by the developer.

If the leaking room passes the warranty period, all parties are not at fault, because the waterproof layer naturally ages and causes water leakage. It needs to be repaired by itself.

Legal basis: Article 7 of the Measures for Quality Warranty of Housing Construction Projects promulgated by the Ministry of Construction states that under normal use, the minimum warranty period of housing construction projects is:

(a) the basic project and the main structure project are the reasonable service life of the project specified in the design documents;

(2) 5 years for roofing waterproof works, toilets, rooms and external walls with waterproof and anti-leakage requirements;

(3) The heating and cooling system consists of two heating periods and cooling periods;

(four) electrical pipelines, water supply and drainage pipelines, equipment installation for 2 years;

(five) the renovation project is 2 years.

The warranty period of other projects shall be agreed by the construction unit and the construction unit.
