Prefabricated Panel Structure Houses to Be Demolished
Not all prefabricated panel structure houses are to be demolished; only those identified as having safety hazards or included in urban renewal and demolition plans will be demolished. Specifically, the following two types of prefabricated panel structure houses will be demolished:
The first type consists of houses identified by professional institutions as having safety hazards. The 2025 policy precisely targets high-risk houses, with D-grade dilapidated houses being the primary focus for demolition. Being classified as a D-grade dilapidated house by a professional institution means that the structural safety of the house has reached a dangerous state, manifested by: foundation settlement exceeding 5 centimeters, which may lead to overall tilting or partial collapse of the house; cracks in load-bearing walls wider than 1 millimeter, directly affecting the wall's load-bearing capacity; and earthquake resistance levels below 70% of current standards, making them highly susceptible to structural damage during natural disasters such as earthquakes. Additionally, houses that are unable to withstand natural disasters are also prioritized for demolition, such as buildings with earthquake resistance below 70% of current standards or houses at risk of collapse due to low-lying terrain and poor drainage during floods. These houses pose a direct threat to the lives and property of residents due to their severely inadequate safety performance and must be demolished to eliminate hazards.
The second type consists of houses already included in urban renewal and demolition planning areas. According to the 2026 policy, the governance of prefabricated panel houses is included in the scope of urban renewal and the renovation of dilapidated housing, with treatment methods including original-site reconstruction and expropriation and resettlement. If a house is located within the planning scope of major infrastructure projects such as subways and elevated highways, or if the land use needs to be adjusted due to urban functional upgrades (e.g., for commercial areas or public facility land), the house may be demolished even if its structure is safe, as it may affect urban planning. Such demolitions are guided by public interests, with residents' rights and interests protected through expropriation compensation or resettlement plans, while promoting urban space optimization and functional enhancement.
It should be noted that for prefabricated panel houses that have not been identified as D-grade dilapidated houses, are not included in demolition plans, and are structurally safe, the policy encourages enhancing safety through reinforcement and renovation rather than direct demolition. Reinforcement measures may include adding structural columns, reinforcing load-bearing walls, and improving earthquake resistance, with specific plans to be determined after evaluation by professional institutions.
