How to Demolish Prefabricated Panel Houses

The demolition of prefabricated panel houses requires meeting specific conditions and following strict procedures. It is not a one-size-fits-all approach but rather a classified disposal method based on the principles of safety first and precise governance.

I. Demolition Conditions: Three Types of Houses Given Priority

1. Grade D Dangerous Houses: These are houses whose load-bearing structures fail to meet safety requirements as determined by professional institutions (e.g., foundation settlement exceeding 5 centimeters, cracks in load-bearing walls wider than 1 millimeter, and seismic resistance levels less than 70% of current standards). These houses must be demolished due to the risk of collapse.
2. Houses with Insufficient Disaster Resistance: Houses with seismic resistance levels less than 70% of current standards or those prone to damage in floods (e.g., prefabricated panel houses with poor integrity, which had a collapse rate more than three times that of brick-concrete structures during the Tangshan earthquake) should be prioritized for demolition.
3. Houses Affecting Urban Planning: Residential buildings located within the planning scope of major infrastructure projects such as subways and viaducts need to make way for urban planning.

II. Demolition Ratio Restrictions

According to policies, within a single urban renewal unit, the demolished floor area should not exceed 20% of the current total floor area in principle, and the demolition-to-construction ratio should not exceed 2. In actual renovations, only about 17% of old residential areas nationwide require demolition and reconstruction to avoid excessive demolition and construction.

III. Demolition Process

1. Safety Appraisal: A qualified institution issues a House Safety Appraisal Report, assessing the grade according to the Standards for Appraisal of Dangerous Houses. Only Grade C (partially dangerous houses) and Grade D (entirely dangerous houses) may be considered for demolition, with Grade D houses requiring mandatory demolition and Grade C houses eligible for repair, reinforcement, or reconstruction.
2. Classified Disposal: Grade D dangerous houses are directly demolished and rebuilt; Grade C dangerous houses are preferably handled through repair, reinforcement, or reconstruction; non-dangerous houses are mainly renovated (e.g., repairing walls and improving sound insulation and heat insulation).

IV. Compensation Plans

Residents can choose their preferred compensation method:

• Monetary Compensation: Not less than 110% of the market price of surrounding commercial housing.
• Property Rights Exchange: Replacement of new houses at a certain ratio (e.g., residential buildings in Handan are replaced at a ratio of 1:1.1).
• Housing Voucher Settlement: Purchase of commercial housing in designated areas with policy incentives.
• Original Site Relocation: Some projects support relocation to newly built houses.

V. Practical Challenges

Demolition requires coordination of complex property rights, disagreements among residents regarding compensation, financial pressures, and dynamic adjustments to planning. Local governments need to prioritize funding for Grade D dangerous houses and basic renovations.
