Demolition of Prefabricated Slab Houses in Jiangsu

Not all prefabricated slab houses in Jiangsu are demolished; instead, they are classified and handled based on the results of housing safety assessments. The specific handling methods are as follows:

I. Class A and Class B Houses
Housing safety assessments classify houses into four grades: A, B, C, and D. Class A houses are structurally safe, while Class B houses have some dangerous components that do not affect the main structure. For these two types of houses, daily maintenance is the primary approach, and living conditions can be improved through renovation projects in old residential areas. Renovation work typically includes roof repairs, replacement of aging pipelines, elevator installations, and other infrastructure upgrades. For example, during the 14th Five-Year Plan period, Yangzhou completed the renovation and upgrading of 781 old residential areas, and in 2026, it advanced the renovation of another 56 old residential areas, all aiming to maintain and enhance the functionality of Class A and Class B houses.

II. Class C Dilapidated Houses
Class C houses are defined as partially dilapidated, and their handling methods include partial reinforcement, restricted use, or observation. For such houses, the central budget's urban renewal special fund provides support. For renovation projects of dilapidated houses on state-owned land identified as Class C or D, the subsidy standard does not exceed 70% of the total approved project investment. This policy aims to reduce renovation costs through financial subsidies and encourage property owners or management units to promptly repair houses with partial safety hazards.

III. Class D Dilapidated Houses
Class D houses are considered entirely dilapidated, and the handling requirements are more stringent. According to regulations, Class D dilapidated houses should immediately cease use and prohibit entry, and they must be demolished or handled as a whole according to the requirements of the local government. The 15th Five-Year Plan for Urban Renewal issued by the State Council in 2026 explicitly proposes accelerating the demolition and renovation of Class D dangerous housing and plans to renovate more than 500,000 units (rooms) of Class C and D dangerous housing and prefabricated slab houses on state-owned land in cities and counties during the 15th Five-Year Plan period to eliminate major safety hazards.

IV. Special Renovation Models
Some regions have explored innovative renovation methods for prefabricated slab houses. For example, some prefabricated slab buildings in Xieqiao Lane Community, Tianning District, Changzhou, which had significant safety hazards, were renovated and rebuilt using a model of "community-led, government-guided, jointly funded, and in-situ reconstruction." This model integrates property owners, the government, and social capital to achieve structural safety upgrades while retaining the original residential functions, providing a reference example for the renovation of similar houses.
