Requirements for Renovating Prefabricated Panel Houses
Renovating prefabricated panel houses must meet requirements in planning approval, quality and safety, building safety assessment, and priority removal of specific types.
Planning and Approval: Renovation must align with local overall land use planning, urban and rural planning, and other requirements. Construction is strictly prohibited in prohibited areas such as farmland protection zones and ecological protection red lines. Before renovation, an application must be submitted to relevant departments, go through the approval process, and obtain the necessary permits before construction can commence. This is a prerequisite for renovation to ensure that the renovation behavior is legal and compliant.
Quality and Safety: During the renovation process, the structural safety and functional rationality of the house must be ensured, with particular attention to safety factors such as earthquake resistance, wind resistance, and fire prevention. The use of general-purpose standard design drawings is encouraged to enhance building design standards. Construction personnel must possess the corresponding skills and experience, and some regions promote craftsman training and management. Township governments or relevant departments will strengthen supervision during the construction process, conduct regular inspections, promptly rectify problems, and carry out acceptance inspections after completion to comprehensively ensure the quality and safety of the renovated houses.
Building Safety Assessment: The building safety assessment report is of crucial importance. It classifies buildings into four grades: A, B, C, and D. Grade A indicates structural safety, Grade B means individual components are dangerous but do not affect the main structure, Grade C represents a partially dilapidated building, and Grade D signifies an overall dilapidated building. The assessment result determines the disposal path. Houses graded A or B with no major issues in the main structure are suitable for old residential area renovation. Grade C dilapidated buildings with repair potential enter the repair and reinforcement path, which includes strengthening walls, beams, columns, floor slabs, foundations, and enhancing earthquake resistance. Grade D dilapidated buildings, whose structural safety has reached a dangerous state, are given priority for removal.
Priority Removal of Specific Types: The 2025 demolition policy precisely targets two types of high-risk buildings, namely Grade D dilapidated buildings and prefabricated panel houses built before the 1980s. In addition, buildings that are difficult to withstand natural disasters, such as those with earthquake resistance below 70% of the current standard, or those vulnerable to floods, as well as buildings that affect urban planning, such as residential buildings within the planning scope of major infrastructure projects like subways and elevated highways, are also on the priority removal list.
