Overall Prefabricated Panel Houses

The renovation or demolition of prefabricated panel houses should be classified and handled according to the actual condition of the houses, rather than a one-size-fits-all approach of complete demolition. The specific situations are as follows:

Prefabricated Panel Houses Requiring Demolition and Reconstruction

1. Severe Structural Safety Deficiencies
   Prefabricated panel houses that have been professionally assessed and meet the criteria for D-grade dilapidated houses must be demolished and rebuilt. These houses typically exhibit issues such as foundation subsidence and significant damage to the main structure (e.g., cracks in load-bearing walls, fractures in floor slabs), making it impossible to meet safety requirements through reinforcement and repair. For example, during the 2024 national building safety inspection, over 35% of prefabricated panel houses showed隐患 (potential hazards) such as wall cracks and loose floor slabs; if assessed as D-grade dilapidated houses, they require demolition.

2. Inadequate Disaster Resistance
   Due to improper handling of structural joints, prefabricated panel houses generally have weak earthquake resistance. If a house is located in a high earthquake-risk area or is assessed as unable to withstand the local basic seismic intensity, it needs to be demolished and rebuilt to ensure resident safety.

3. Conflict with Urban Planning
   If a prefabricated panel house is located within the development scope of the urban core area, within the red line for infrastructure construction (e.g., subway, road expansion), or obstructs urban functional upgrades (e.g., fire lanes, public green space planning), demolition is necessary to achieve efficient land use.

Prefabricated Panel Houses Primarily for Renovation

1. Good Structural Safety but Outdated Functionality
   For prefabricated panel houses with intact main structures and no serious safety hazards, priority should be given to reinforcement renovation and functional upgrades. For example, extending the service life by adding seismic components, repairing structural cracks, and updating water and electricity pipelines, while improving community amenities (e.g., installing elevators, adding parking spaces).

2. Within the Scope of Old Community Renovation Policies
   According to the Ministry of Housing and Urban-Rural Development's plan, the renovation of old residential communities built before the end of 2000 will be basically completed by the end of 2025. Most prefabricated panel houses that have been in service for more than 25 years and do not meet the criteria for dilapidated houses will be included in the old community renovation system, with measures such as roof repair, exterior wall insulation, and greening optimization to enhance living quality.

Policy Basis and Implementation Principles

1. Classification and Disposal Principles
   The 2025 policies clearly classify dangerous housing into C-grade (partially dangerous) and D-grade (overall dangerous): D-grade must be demolished or rebuilt, while C-grade should primarily be reinforced and renovated, avoiding extensive demolition and construction.

2. Urban Renewal Orientation
   The policies emphasize efficient land use in the era of existing stock, prioritizing the revitalization of existing spaces through renovation and only implementing demolition for necessary dilapidated houses, balancing safety needs with resource conservation.
