Latest Jiangsu Prefabricated House Standard

Admin September 18, 2026

The latest complete content of the Jiangsu prefabricated house standard has not been found yet, but there is a new draft standard for residential design in Jiangsu Province seeking opinions, which involves some regulations related to residential housing.

Floor Height Regulations in the Draft New Standard for Residential Design in Jiangsu Province

The Provincial Department of Housing and Urban-Rural Development has issued a newly revised 'Residential Design Standard (Draft for Opinions)', which clearly stipulates the floor heights for different types of residential housing, such as newly built commercial residential housing and affordable housing. The floor height of newly built commercial residential housing should not be less than 3.1m, while that of other types of residential housing, such as affordable housing, should not be less than 3.0m. For residential buildings with more than four floors, the floor height should not exceed 3.6m (except for local raised areas). Meanwhile, for residential housing equipped with underfloor heating, ducted fresh air systems, or centralized air conditioning systems, considering that these facilities require a certain amount of installation space, the floor height should not be less than 3.15m. These regulations aim to ensure that there is sufficient space inside residential housing to meet the normal living needs of residents and improve living comfort.

Indoor Net Height Regulations in the Draft New Standard for Residential Design in Jiangsu Province

In addition to floor height, the draft for opinions also stipulates the indoor net heights of bedrooms and living rooms. The indoor net height of bedrooms and living rooms should not be less than 2.60m, and the local net height should not be less than 2.20m. Moreover, the area with a local net height lower than 2.60m should not exceed one-third of the indoor usable area. Indoor net height is one of the important factors affecting the living experience. A reasonable indoor net height can avoid a sense of spatial oppression and make residents feel more comfortable and at ease when engaging in indoor activities.

Currently, there are approximately 18.5 million prefabricated panel houses across the country, which are classified into four grades—A, B, C, and D—according to the 'Standard for Dangerous House Appraisal'. More than 50% of the prefabricated panel buildings are rated as Grade A or B, indicating that their structures are basically safe. Only about 15% are classified as Grade D dilapidated houses that must be demolished. However, these data do not specifically represent the situation of the prefabricated house standard in Jiangsu. At present, the latest complete content of the Jiangsu prefabricated house standard has not been obtained.
