As China’s housing system reform deepens, part of the Code underwent revision in the late 1990s, forming the 2002 version. This version has been used for over a decade now. Over the past ten years, China has seen continuously accelerated city development and urbanization. It is also a crucial moment when Chinese people enjoy better and better livelihood. The Code more or less has some applicability issues in the face of the tremendous changes in the development of Chinese economic society, including changes in governmental functions, continuously deepened housing system reform, the aging population, diversification in residential area development and construction mode and scale, as well as the variety in building designs. During the standard review carried out by the Ministry of Housing and Urban-Rural Development of PRC (MOHURD) in April 2013, experts came to a conclusion about the review of The Code that “comprehensive revision should be done on the basis of preliminary study.

为有序、稳妥、恰当地开展修订工作，住房和城乡建设部城乡规划标准化技术委员会（以下简称城乡规划标委会）针对该《规范》修订将面对的主要问题及其技术内容，组织开展了本次配套研究项目，为《规范》的修订提供技术支撑。
In order to revise the Code in an orderly, reliable and appropriate manner, the Technical Standardization Committee of Urban-Rural Planning of MOHURD organized this complementary research project so as to address main problems and study technical content of the revision of the Code, and provide technical support.
