Prefabricated Panel Houses in Chengdu

The prefabricated panel houses in Chengdu have not been completely demolished, mainly due to factors such as housing structural safety, differing opinions among residents, difficulties in demolition, property rights and funding issues, and policy restrictions. Currently, a graded renovation policy is mostly adopted.

I. Reasons for Non-demolition

1. Housing Structural Safety: Some prefabricated panel houses are of steel-concrete structure with a designed service life of over 50 years. If the main structure is intact and regularly maintained, and they are identified as non-dangerous houses by professional institutions, they can still be safely used without mandatory demolition.
2. Differing Opinions Among Residents: Elderly residents have emotional attachments to their old homes and are less willing to relocate; younger residents are more inclined to exchange for new homes, but disagreements over compensation plans often lead to stalled demolitions.
3. Difficulties in Demolition Implementation: Prefabricated panel houses have significant structural differences, and demolition can easily trigger safety hazards in adjacent buildings. Construction may cause dust and noise pollution, requiring complex environmental approvals and increasing implementation costs.
4. Property Rights and Funding Issues: The property rights of housing reform houses are complex, making it difficult to negotiate compensation standards. Residents are reluctant to self-finance, and developers need to balance profits with demolition costs, leading to slow project progress.
5. Policy Restrictions: Current regulations prioritize the demolition of only 17% of dangerous houses or plots urgently needed for planning. If a house is not within the urban renewal red line, it may be retained for a long time.

II. Policy Disposal Methods
Sichuan Province promotes graded handling:

• Grade A or B: The structure is basically safe, with renovation as the main approach, including refurbishing exterior walls, replacing water and electricity pipelines, repairing leaks, and improving fire safety facilities. The government is responsible for public areas, while residents finance their own renovations or elevator installations.
• Grade C: There are local structural hazards, with priority given to seismic reinforcement (such as adding load-bearing columns, repairing cracks, and removing rust) and replacing supporting facilities. Demolition and reconstruction can only be applied for when technical reinforcement is impossible or meaningless, but the conditions are stringent.
• Grade D: The house is completely damaged and must be vacated, included in urban renewal or demolition projects, with disposal methods including demolition and reconstruction, monetary compensation, or resettlement housing.

III. Renovation Funding and Seismic Requirements
Financial investments are mainly used for public facilities (such as road repairs, greening, and pipeline renovations); residents need to bear part of the construction costs for in-situ reconstruction. The policy emphasizes that renovations must meet current seismic standards, and if the original house lacks seismic structures, reinforcement is mandatory.

IV. Specific Case
Central Garden Phase II (Wuhou District) is a prefabricated panel commercial housing community. In 2018, homeowners initiated a "self-demolition and self-reconstruction" proposal, and by 2023, the approval rate reached 99%. However, due to insufficient policy basis, it has not yet been implemented, and the plan has been submitted to the government for approval.
