How many years is the waterproof warranty period of commercial housing?

The waterproof works of the roof, waterproof toilet and room exterior wall of commercial housing are impervious for 5 years. Developers should be responsible for the quality of commercial housing sold. Both parties agree on the warranty scope, warranty period and warranty responsibility in the contract. Housing warranty period refers to the period when the property development and construction unit undertakes the warranty responsibility to the owner after the property is delivered for use. The warranty period of commercial housing shall not be less than the warranty period stipulated in the quality guarantee issued by the construction contractor to the real estate agent. The real estate agent is responsible for the warranty of the purchaser, but it is the construction contractor who actually undertakes the warranty work, and the warranty period shall be subject to the time promised by the construction contractor to the real estate agent. The warranty period is calculated from the date of delivery. In the process of living, if the house leaks during this period, the owner should claim compensation from the developer and ask for maintenance. The project warranty period should be calculated from the moment the house is delivered, and should be reflected in the house purchase contract.

Legal basis:

"Regulations on Quality Management of Construction Projects" Article 40 Under normal conditions of use, the minimum warranty period of a construction project is:

(a) the reasonable service life of the building foundation engineering, foundation engineering and main structure engineering 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 and decoration works, for 2 years.

The warranty period of other projects shall be agreed by the employer and the contractor.

The warranty period of the construction project shall be calculated from the date when the project is completed and accepted.

Derivative problem:

Who should I talk to if I have any questions after the warranty period?

After the warranty period, you can find the owners' committee or the property management unit. The exclusive part of the house is maintained by the owner himself, and some parts of the house or the facilities and equipment used in the house can apply for the use of public special maintenance funds for the house, which will be approved by the construction real estate department or the owners' meeting.
