17% Prefabrication Rate in Housing Construction

When the prefabrication rate of housing construction is 17%, it is necessary to determine compliance with policy requirements based on the building type and height.

According to the document (Hu Jian Jian Cai [2025] No. 250) issued by the Shanghai Housing and Urban-Rural Development Management Committee, the requirements for the prefabrication rate or assembly rate of residential buildings are directly related to building height. For super high-rise residential buildings with a height exceeding 100 meters (excluding 100 meters), the policy explicitly requires that the prefabrication rate of individual buildings should be no less than 15%, or the assembly rate of individual buildings should be no less than 35%. If a residential building has a prefabrication rate of 17%, it may fall into the category of such super high-rise buildings using the prefabrication rate indicator. In this case, it is necessary to further verify whether the actual height of the building exceeds 100 meters: if it meets the height requirement, a prefabrication rate of 17% already satisfies the policy minimum; if the building height does not reach 100 meters, it is necessary to confirm whether other clauses apply or whether there are any special exemption circumstances.

For non-residential buildings (such as public buildings, industrial buildings, etc.), Document Hu Jian Jian Cai [2025] No. 250 does not directly mention specific requirements for the prefabrication rate value of 17%. The standards for the prefabrication rate or assembly rate of such buildings may be stipulated by other special policies or local regulations, and further analysis is required in combination with specific building types and local details. For example, public buildings may place more emphasis on the assembly rate indicator, while industrial buildings may have differentiated requirements due to their structural particularities.

Key points to note:

1. Building type and height are the core criteria for judgment. For residential buildings, it is necessary to first confirm whether the height exceeds 100 meters, while for non-residential buildings, it is necessary to look up special policies for the corresponding category.
2. Policies may be subject to dynamic adjustments. Document Hu Jian Jian Cai [2025] No. 250 is the currently valid version, but in the future, if it is revised or supplementary clauses are issued, the latest document shall prevail.
3. Comprehensive evaluation is required in actual projects. The prefabrication rate is only one of the indicators for evaluating prefabricated buildings. It is also necessary to comprehensively determine project compliance in combination with the assembly rate, full decoration ratio, green building standards, etc.

If the building is a super high-rise residential building with a height exceeding 100 meters, a prefabrication rate of 17% complies with policy requirements; if it is of other types, it is necessary to further check local regulations or consult the competent authorities to confirm compliance.
