According to the Chongqing Municipal Housing and Urban-Rural Development Commission, Chongqing's “Technical Guidelines for Good Houses” will be implemented on December 15, 2025, setting a “new standard” for affordable housing construction in Chongqing based on dimensions such as safety and resilience, comfort and livability, green and low carbon, smart and convenient. In terms of safety and resilience, Chongqing encourages key areas to adopt seismic resistance measures higher than the requirements of the regulations. At the same time, a full-chain fire protection system will be established, and the configuration of fire protection facilities will be strengthened in key areas such as electric bicycle charging areas. In terms of comfort and livability, Chongqing proposed three types of “60, 90, and 120” packages suitable for families with different numbers of people, with a floor height of no less than 3 meters to ensure spacious and transparent space, and put forward quantitative requirements for physical environmental indicators such as indoor lighting, ventilation, and sound insulation. In terms of green and low carbon, Chongqing has made it clear that the proportion of green building materials used is not less than 70%. Promote energy-saving technologies such as solar photovoltaic power generation and sponge city facilities.
