National Demolition of Prefabricated Panel Houses

The handling of prefabricated panel houses across the country does not involve comprehensive demolition but rather focuses on 'governance and renovation.' This is achieved through various approaches such as safety inspections, reinforcement and renovation, original demolition and reconstruction, and expropriation and resettlement, with demolition being carried out only for houses that meet specific conditions.

Strictly Defined Scope of Demolition, Focusing on High-Risk Houses

According to policies, prefabricated panel houses eligible for demolition must meet the following criteria:

1. Grade D Dangerous Houses: The load-bearing structures of these houses can no longer meet safety requirements for use, and the entire building poses significant risks, such as severe wall cracking and beam-column deformation. Minor repairs cannot address the fundamental issues, so priority is given to demolition and reconstruction.
2. Some Grade C Houses: If localized hazards in a house can be eliminated through engineering measures (such as reinforcement and maintenance), repair methods are preferred. However, if the building is severely aged with concentrated functional defects (such as the lack of elevators and aging pipelines) and residents have a unified willingness for renovation, it may be included in the reconstruction scope.

Strictly Limited Demolition Proportions to Avoid Large-Scale Demolition and Construction

Policies set clear upper limits on the scope and scale of demolition:

• Demolition Area Proportion: Within a single urban renewal unit, the demolished building area should not exceed 20% of the current total building area in principle, preventing excessive demolition and construction from impacting urban functions.
• Demolition-to-Construction Ratio Control: The demolition-to-construction ratio (the ratio of demolished area to newly built area) in a project should not exceed 2, ensuring reasonable building density and floor area ratio after renovation and avoiding resource waste.

Renovation as the Mainstream Approach, with Demolition Accounting for Only a Small Portion

It is estimated that by 2026, approximately 26,000 old residential communities across the country will be included in renovation plans, with only about 17% truly requiring demolition and reconstruction, while the remaining 83% will be handled through reinforcement, renovation, or functional upgrades. The policy emphasizes 'precisely targeting high-risk houses,' meaning that based on housing safety appraisal reports, houses with structural safety hazards will undergo demolition or renovation, rather than a 'one-size-fits-all' approach of demolishing all prefabricated panel houses.

Summary

The handling of prefabricated panel houses across the country adheres to the principle of 'safety first and classified strategies.' Through scientific assessment and precise intervention, it balances residents' safety needs with the pace of urban renewal. Demolition is targeted only at Grade D dangerous houses and some eligible Grade C houses, with strict limits on area proportions and demolition-to-construction ratios. Overall, renovation and reinforcement are the mainstream approaches.
