Problems with Prefabricated Finished Housing

The problems with prefabricated finished housing (such as prefabricated panel houses) mainly include four aspects: housing quality and living performance, governance and renovation, developer-related issues, and the diversity of governance paths.

Housing Quality and Living Performance Issues:
Prefabricated panel houses are primarily composed of cement components. Although steel bars are incorporated, their overall earthquake resistance is weaker than that of modern buildings, and they offer insufficient protection against disasters such as earthquakes or floods. Their sound insulation and thermal insulation effects are poor, making them prone to stuffiness in summer and coldness in winter, with significant sound interference between neighbors. The internal structure is fixed, with walls mostly serving as load-bearing structures, making large-scale spatial renovations difficult and limiting personalized living needs. Additionally, cement components are prone to cracking due to aging, increasing the risk of water leakage and affecting residents on upper and lower floors. The design lifespan is typically 30-50 years, and houses built in the 1970s-1980s are approaching or have exceeded their service life, with aging problems being widespread.

Governance and Renovation Challenges:
Complex property rights relationships are one of the main obstacles. Most prefabricated panel houses are "housing reform houses," and residents have deep emotional attachments to them, making it difficult to unify demolition compensation plans and hindering project progress. Demolition and reconstruction costs are high, involving land compensation, resettlement fees, etc. Local government funds are prioritized for dilapidated housing governance, making it difficult to quickly demolish non-D-grade dilapidated houses or those in core areas. Current policies adopt differentiated standards for dilapidated housing appraisal and urban renewal. Some houses, although aged, have sound main structures and are prioritized for "old renovation" (such as reinforcement and pipeline replacement) rather than demolition. Dynamic planning adjustments also increase uncertainty in demolition.

Developer-Related Issues:
Some developers operate without full qualifications, engaging in illegal pre-sales or misleading consumers through false advertising, and even misappropriating pre-sales funds, leading to project stalls. Pre-sales contracts may contain unfair clauses, or developers may unilaterally change plans or designs without notifying buyers. After delivery, common issues include wall cracks, leakage, and other quality problems, as well as disputes over delayed delivery or non-compliance with delivery standards.

Diversity of Governance Paths:
Based on housing safety appraisal results (grades A-D), disposal methods include old residential area renovations (such as roof repairs, pipeline replacements, elevator installations), repair and reinforcement (for C-grade dilapidated houses), and expropriation and demolition (requiring project implementation or inclusion in reconstruction plans), among others, not all of which involve demolition. Policies emphasize classified disposal, prioritizing居住安全 (living safety) while also considering resource utilization efficiency.
