How to Demolish a Prefabricated Slab Structure House

The demolition of a prefabricated slab structure house requires comprehensive decision-making based on structural safety, planning needs, or policy requirements, and must strictly adhere to legal procedures and measures to protect residents' rights and interests.

I. Basis for Demolition Decisions

1. Structural Safety Hazards: Houses identified as Grade D dangerous buildings by professional assessment (e.g., foundation settlement exceeding 5 cm, cracks in load-bearing walls wider than 1 mm, seismic resistance below 70% of current standards) must be prioritized for demolition due to excessively high repair costs or inability to meet safety standards. Local governments will organize legal procedures such as safety assessments, plan formulation, and public announcements before implementation.
2. Urban Planning Needs: If a house is located within the scope of major infrastructure projects like subways or elevated highways, or urban renewal plans, it must be demolished according to planning requirements. Such demolitions require advancement through stages including planning formulation and compensation negotiations.
3. Old Residential Area Renovation Policies: For buildings with minor safety hazards that still retain usability, governments tend to extend their lifespan through renovations (e.g., exterior wall insulation, pipeline updates). According to 2026 policies, 115,000 old urban residential areas nationwide will commence renovations, with only about 17% requiring demolition and reconstruction.

II. Legal Protections and Residents' Rights During Demolition

1. Safety and Legality: Prior to demolition, structural assessments and safety evaluations must be conducted to ensure no risks are posed to surrounding buildings or residents. The 2026 policy specifies that demolition areas within urban renewal units shall not exceed 20% of the current total building area, with a demolition-to-construction ratio not exceeding 2.
2. Compensation and Resettlement: Governments must provide reasonable compensation, including monetary compensation (not less than 110% of surrounding commercial housing market prices, e.g., compensation in Shanghai's Dong'an No.1 Village reached RMB 135,000/㎡) or property rights exchanges (e.g., Handan offers a 1:1.1 replacement ratio). Households with per capita living areas below 30㎡ shall receive compensation to meet minimum area requirements.

III. Practical Operational Recommendations

1. Understand Policies: Residents should proactively inquire about local demolition standards, compensation methods, and resettlement plans to avoid information asymmetry.
2. Seek Professional Advice: Consult government departments or lawyers when necessary to ensure rights are not infringed upon.
3. Participate in Negotiations: Actively engage in public announcements and consultation activities organized by the government, raise reasonable demands, and supervise the fairness of the demolition process.

Demolition must balance safety, planning, and livelihood concerns, strictly operating in accordance with laws and regulations to safeguard residents' legitimate rights and interests.
