Safety has become the bottom line and fundamental goal of urban renewal with the accelerated urbanization process. Building a safe and stable urban residential environment is a meaningful way to improve cities’ “social-ecological” resilience. Based on the theory of environmental crime prevention and space syntax, taking Tiexinli old residential area in Qinhuangdao City as the research object, using Depth map software to quantitatively analyze the integration degree, synergy degree, connectivity degree, depth value, visual clustering coefficient, and choice value of the residential space, the results show that the accessibility of the spatial system of the old residential area is differentiated. The accessibility of the by-pass road is the lowest and lacks activity support. The spatial layout of the residential area is single and concurrent, and the entrances, exits, and the subsidiary road fail to play a good role in ” access control. ” The environment and landscape of green space between houses and negative space in the residential area are poorly maintained, and the visibility effect is limited. Therefore, the renovation of the old residential area should focus on optimizing the road system, increasing the monitoring of the activities of the people, and enriching the activities of the public space. This research contributes to addressing potential crime issues in urban renewal. It offers feasible and forward-looking approaches to crime prevention and control in the redevelopment of old residential areas in Asian countries. Additionally, this method can be applied in the planning and design of new residential areas to identify and rectify potential crime risks within design schemes, ensuring the safety and living quality of residential communities.
