Treatment of Prefabricated Slab Houses in Ningbo
The treatment methods for prefabricated slab houses in Ningbo are divided into three categories based on the specific conditions of the houses: mandatory demolition, renovation, and preservation.
Mandatory Demolition: This category primarily targets houses with significant safety hazards, such as those identified as Grade D dilapidated houses by professional institutions (with issues like cracked walls, subsided foundations, and loose floor slabs). The structures of these houses are severely damaged and cannot be repaired through reinforcement. It also includes houses that affect major planning, such as those located in urban core areas or obstructing municipal engineering projects, as well as houses built before 2000 with no reinforcement value. According to policy requirements, these houses must be cleared by the end of 2027, and the principle of 'relocation before demolition' shall be implemented to ensure the safety of residents. For example, a 40-year-old prefabricated slab house in Beilun Beijixing Village, Ningbo, has been included in the mandatory demolition scope due to serious safety hazards.
Renovation: This category applies to houses with basically safe structures but functional defects, such as Grade B/C prefabricated slab houses (with issues like water leakage, poor insulation, and outdated facilities). These houses will undergo comprehensive upgrades by 2028, including structural reinforcement, functional improvements (such as updating water and electricity lines and installing elevators), and convenience-oriented renovations (such as adding parking spaces and improving green spaces). The renovation costs are mainly subsidized by the government. For example, during the renovation in Xi'an's Lianhu District, the government subsidized 90%, with each household only needing to bear a little over 2,000 yuan. Ningbo is also promoting the organic renewal of villages by increasing subsidies for the renovation of old rural houses and implementing renovations on eligible prefabricated slab houses.
Preservation: This category targets prefabricated slab houses built after 2005 with high construction standards and intact structures. These houses can continue to be used but must undergo safety inspections every five years, with the inspection costs covered by residential special maintenance funds. Due to their relatively recent construction and good quality, these houses do not require demolition or large-scale renovation but need regular inspections to ensure long-term safety.
