When Will Precast Panel Houses Be Demolished?

There is no unified regulation on when precast panel houses will be demolished. The decision depends on a comprehensive assessment of the house's safety condition, disaster resistance capability, and urban planning. Demolition procedures will only be initiated when specific conditions are met.

I. Core Conditions for Demolition

1. Meeting the criteria for dangerous houses According to the "Standards for the Appraisal of Dangerous Houses," the safety of houses is classified into four levels: A (safe), B (basically safe), C (partially dangerous), and D (overall dangerous). D-grade dangerous houses, due to foundation subsidence, severe damage to the main structure that cannot be repaired through renovation, must be demolished or rebuilt. C-grade dangerous houses can be addressed through reinforcement or reconstruction, but they may also be included in the demolition scope if the renovation costs are too high or the effects are limited.
2. Substandard disaster resistance capability Although some precast panel houses may function normally in daily use, they are prone to structural damage during disasters such as earthquakes and floods. If professional assessments determine that their disaster resistance capability is significantly lower than current standards, they may be listed for demolition.
3. Conflict with urban planning If a house is located within planning areas for subway construction, road widening, or urban core development, and the benefits from demolition can cover the reconstruction costs, it may be demolished according to the plan. For example, the "15th Five-Year Plan for Urban Renewal" in 2026 explicitly requires the "renovation of more than 500,000 sets (units) of C- and D-grade dangerous housing and precast panel houses," with some of them requiring demolition and reconstruction.

II. Policy Basis and Restrictions

1. The principle of 'no large-scale demolition and construction' The "Guidelines for Optimizing the Revitalization of Urban Stock Space" and the "Opinions on Continuously Promoting Urban Renewal Actions" issued in 2025 emphasize that urban renewal should be guided by classified handling and prioritizing the vulnerable, avoiding large-scale demolition.
2. Restrictions on demolition proportion According to policies in 2026, the demolished floor area within an urban renewal unit should not exceed 20% of the current total floor area in principle, and the demolition-to-construction ratio should not exceed 2. Calculations by the China Index Academy show that among the renovations of old residential communities nationwide in 2026, precast panel houses requiring demolition and reconstruction accounted for only about 17%.
3. Renovation preferred over demolition Data from the Ministry of Housing and Urban-Rural Development indicates that nearly 65% of old residential community renovation projects adopt a preservation and renovation approach (such as installing elevators and updating pipelines), with only about 35% involving demolition and reconstruction. The vast majority of precast panel houses will improve their living quality through old renovations rather than direct demolition.

III. Key Judgment Logic

The core basis for deciding whether to demolish a house is the house safety appraisal report, rather than the age or structural type of the house. Even if a house is of precast panel structure, if its safety level is A or B and its disaster resistance capability meets the standards, it will generally not be demolished. Conversely, even if a house is relatively new, if it is appraised as a D-grade dangerous house, it must be dealt with immediately.
