Demolition of Prefabricated Panel Houses in Zhejiang Province

The demolition of prefabricated panel houses in Zhejiang Province is not being carried out comprehensively but rather through a conditional, step-by-step, and differentiated strategy, with the results of housing safety appraisals and residents' wishes as the core basis. The specific policies and practical points are as follows:

1. Policy Orientation: Emphasis on Self-Renewal and the Principle of 'Owner-Led'
Zhejiang Province encourages the self-renewal of old residential areas with prefabricated panels built before 2000 and with prominent structural hazards through 'original demolition and reconstruction'. The policy clearly adheres to the principle of 'owner-led, government-guided, and market-operated', meaning that owners independently decide whether to renew and drive the renovation through fundraising, while the government only provides policy support and procedural guidance. This model avoids 'one-size-fits-all' demolition, fully respects residents' wishes, and reduces financial pressure.

2. Scope of Application: Focus on Dangerous Houses and Non-Self-Contained Residences, Prioritizing High-Risk Areas
The policy prioritizes two types of houses:

• Houses appraised as Grade C or D dangerous houses: Among them, Grade D dangerous houses, due to the risk of overall collapse, require 'accelerated demolition and renovation'; Grade C dangerous houses are mainly reinforced and repaired.
• Non-self-contained residences and old residential areas with severely inadequate facilities: Prefabricated panel houses, due to their weak seismic performance and limited design life (usually 50 years), are listed as key objects encouraged for renewal. However, it should be noted that not all prefabricated panel houses need to be demolished. Only when the house has structural safety hazards or residents have a strong willingness to renew will it be included in the renovation scope.

3. Residents' Wishes: High Approval and Signing Rates as Prerequisites for Project Initiation
To ensure the smooth progress of renovation, the policy sets strict thresholds:

• The initial approval rate must reach 95%: Residents of the community need to express strong support in the early stages.
• The formal signing rate must reach 100%: Before the project starts, all owners must complete the signing to avoid project stagnation due to individual objections.
  For example, the Changcheng Jiaoyuan Community in Yuecheng District, Shaoxing, became the first successful case of self-renewal of a prefabricated panel community in Zhejiang Province through 100% resident signing.

4. Governance Path: Parallel Demolition and Renovation, Prioritizing Grade D Dangerous Houses
According to the '15th Five-Year Plan for Urban Renewal', the governance of prefabricated panel houses follows the framework of 'steady progress' and is carried out in parallel with 'accelerating the demolition of Grade D dangerous houses':

• Grade D dangerous houses: Due to extremely high safety risks, they need to be immediately demolished and rebuilt.
• Other prefabricated panel houses: Mainly reinforced, repaired, or functionally upgraded, and only demolished and rebuilt through self-renewal when residents strongly request it and the house conditions allow.
  This strategy balances safety needs with resource utilization efficiency, avoiding excessive demolition and resource waste.
