Demolition of Prefabricated Floor Slab Houses in Guangzhou
The demolition of prefabricated floor slab houses in Guangzhou is not a one-size-fits-all approach; instead, it is classified and handled based on the results of housing safety appraisals, with only D-grade dilapidated houses requiring demolition and renovation.
I. Demolition Basis: Centered on Safety Appraisals
According to data from the Ministry of Housing and Urban-Rural Development in 2026, only about 15% of prefabricated panel residential buildings nationwide are appraised as D-grade dilapidated houses (overall danger requiring demolition), while the remaining houses can continue to be used after repair and reinforcement. The State Council's "15th Five-Year Plan for Urban Renewal" explicitly calls for "accelerating the demolition and renovation of D-grade dangerous housing" but does not list prefabricated panel houses as a whole as objects for demolition. The lifespan of prefabricated panel houses depends on maintenance conditions; their designed working life is typically 50 years, and 30 years is not a red line for demolition. The disposal method needs to be determined through professional appraisals.
II. Guangzhou Practice: Classified Governance and Model Innovation
Case of Original Demolition and Reconstruction
Huadu Juqun Street Building No. 2 (built in 1976) suffered from issues such as moldy walls, water leakage, and damaged load-bearing structures. After being appraised as a dilapidated house, original demolition and reconstruction were initiated in March 2024 and completed in January 2025. This project adopted the model of "homeowner-initiated renewal, self-financing, and government subsidies for preliminary expenses" without involving large-scale demolition compensation, providing replicable experience for the renovation of old prefabricated panel houses.Difference from Urban Village Renovation
Although the old renovation project in Lingtang East Area, Tianhe District, involves house demolition, it falls under the scope of urban village renovation and has no direct connection with the special governance of prefabricated panel houses. The core of its renovation is "priority for resettlement," ensuring the rights and interests of villagers through measures such as the construction of rebuilt houses and the lottery for the qualification to exchange for commercial housing. The dismantling is planned to be completed by mid-November 2024.
III. Policy Objectives: Steady Progress Rather Than Forced Obsolescence
The "15th Five-Year Plan for Urban Renewal" proposes to renovate 500,000 sets/units of C-grade (partially dangerous), D-grade dilapidated houses, and prefabricated panel houses by 2030 but emphasizes "steady progress in governance and renovation." The policy explicitly opposes "large-scale demolition and construction" and requires prioritizing the extension of the service life of houses through repair, reinforcement, and functional upgrades, with only irreparable D-grade dilapidated houses undergoing demolition and reconstruction.
Summary: The demolition of prefabricated floor slab houses in Guangzhou should be based on the results of professional appraisals, with D-grade dilapidated houses being the focus of demolition. However, the renovation models are flexible and diverse, and the policy orientation is to "ensure the basics, promote renewal, and prevent risks," avoiding resource waste and social conflicts.
