No agreement, no agreement, no property rectification, no house maintenance period.

Regarding the length of the warranty period, according to Article 33 of the Measures for the Administration of Commercial Housing Sales: "The warranty period of commercial housing shall not be less than the warranty period stipulated in the quality guarantee issued by the construction unit to the real estate developer; If the duration is less than the minimum warranty period determined by the Regulations, the warranty period shall not be less than the minimum warranty period determined by the Regulations. " Therefore, the real estate agent bears the warranty responsibility for the purchaser, but the contractor of the construction project actually undertakes the warranty work, and the warranty period shall be subject to the time promised by the contractor of the construction project to the real estate agent. The "regulations" mentioned in this article refers to the "regulations on the implementation of residential quality warranty and residential use description system for commercial housing" stipulated in Article 32 of the Measures for the Administration of Commercial Housing Sales, in which Article 6 stipulates: "If the state has other provisions on the quality warranty period of residential projects, the warranty period shall be implemented in accordance with the state regulations."

3) According to Article 40 of the State Council's Regulations on Quality Management of Construction Projects, under normal use conditions, the minimum warranty period of construction projects is:

A The foundation engineering, foundation engineering and main structure engineering of building construction are the reasonable service life of the project specified in the design documents (note: this life may reach the service life of the building);

B Roof waterproofing works, leakage prevention for bathrooms, rooms and external walls with waterproof requirements, 5 years;

C heating and cooling system, which consists of two heating periods and cooling periods;

D. Installation and decoration of electrical pipelines, water supply and drainage pipelines and equipment, which is 2 years;

E the warranty period of other projects shall be agreed by the employer and the contractor;

F the warranty period of a construction project shall be calculated from the date of completion and acceptance of the project.

Therefore, it is more accurate to say that "the warranty period of the construction project is calculated from the date of completion and acceptance". Even if the real estate agent and the purchaser agree that the warranty period is calculated from the delivery date, it is likely to subtract the time from the completion and acceptance of the house to delivery. Buyers who buy weifang or xianfang must pay attention to the time limit of the warranty period when collecting the house, so as not to miss the warranty time.
