The rapid development of modern cities, the continuous expansion of the area, and the scale effect brought by the agglomeration of the population also bring the risk of rapid spread of diseases. As a unit of urban organization, the community became the main isolation unit during major public health incidents and played an important role in delaying the spread of the epidemic. Especially in the residential community, from the ecological circle that undertakes residential functions to meet the needs of prevention and control, medical care, commerce, and convenient services. At the same time, it exposes disadvantages such as insufficient public space and insufficient supporting facilities. During the emergency period, different types of residential communities have adopted similar management methods and changes in local spatial morphology, some of which will gradually become public consciousness and be integrated into future community renewal and design. In the post-epidemic era, the resilient cities and healthy cities theories have promoted changes in residential community space. The idea of urban micro-renewal comes from the reflection on large-scale urbanization and over-rational urban planning to improve the quality of residential areas and achieve sustainable development. It has the characteristics of strong restoration, strong continuity, and gradual renewal. This article first sorts out existing urban residential micro-renewal cases and research directions from the morphological changes of urban areas, residential clusters, and building units. Then explores and innovates the methods and content of micro-renewal from the perspective of epidemic prevention. In response to the top-down prevention and control measures of city managers and the bottom-up spatial transformation of residents, it promotes the evolution of formal and informal urban forms.
