Regulations on Prefabricated Panel Houses in Yinzhou District

As of September 2026, Yinzhou District has not introduced specific policies targeting prefabricated panel houses. However, based on the national and local policy frameworks, its management regulations can be summarized as follows:

1. National Policy Orientation: Classified Governance, Prioritizing the Handling of Dangerous Houses According to the State Council's '15th Five-Year Plan for Urban Renewal', prefabricated panel houses are required to undergo classified governance, with the core principle of 'avoiding a one-size-fits-all demolition approach'. Specific requirements include:

• Prioritizing the renovation of Class C and D dangerous houses: Class C (partially dangerous houses) need to be repaired through structural reinforcement and pipeline updates; Class D (entirely dangerous houses), due to high safety risks and low repair value, require the initiation of demolition and reconstruction procedures.
• Renovation goals: During the '15th Five-Year Plan' period, it is planned to renovate 500,000 sets (units) of prefabricated panel houses, with renovation methods covering seismic upgrades, energy-saving renovations, etc., to extend the service life of the houses.
• Demolition conditions: Demolition is only allowed when the house poses significant safety hazards (such as foundation settlement, failure of load-bearing structures) and the repair cost exceeds the cost of new construction.

2. House Safety Appraisal Standards: Four-Level Classification, Scientific Assessment Based on the 'House Safety Appraisal Standards' (JGJ125-2016), the safety of prefabricated panel houses is classified into four levels, and Yinzhou District implements this standard as the basis for governance:

• Class A: Structurally safe, can be normally inhabited without intervention.
• Class B: Individual components are aged (such as cracks in prefabricated panels), but it does not affect the main structure, requiring regular monitoring.
• Class C: The local load-bearing structure does not meet safety requirements (such as deformation of beams and columns), requiring reinforcement before use, and direct demolition is prohibited.
• Class D: The entire house is dangerous (such as severe wall tilting), and it must be immediately demolished to avoid collapse risks. The appraisal must be completed by a professional institution, and the results serve as the core basis for governance decisions.

3. Local Governance Practices: Prioritizing Repair and Reinforcement, Strengthening Monitoring

• Repair and reinforcement cases: For example, Building 53 on Dongdaqiao Road in Chaoyang District, Beijing (with a building age of over 60 years), continues to be used after seismic reinforcement and energy-saving renovations, proving that prefabricated panel houses that meet safety standards can have their service life extended through renovation.
• Regular physical examination system: Nantong City conducts physical examinations of urban residential buildings built over 25 years ago every 10 years, with the interval shortened to every 5 years for prefabricated panel houses; Hefei City conducts physical examinations of prefabricated panel houses built between 1970 and 1990 every 2 years. Yinzhou District may refer to such systems to implement more frequent safety monitoring of prefabricated panel houses.

4. Planning and Management Integration: Rural Areas Must Comply with Village Plans Yinzhou District's 'General Rules-based Village Planning Management Regulations' apply to rural areas outside the urban development boundary, requiring rural construction projects (including rural residential buildings, public facilities, etc.) to comply with national and local construction standards. If prefabricated panel houses are located in such areas, they need to comply with village plans or special plans, but no special regulations have been separately formulated for prefabricated panel houses.
