The search for quality of life in urban areas has become inevitable today. This missing attribute of today’s urban is at the heart of the city debate. Indeed, the latter now faces multiple dysfunctions. This then implies that ist development and management strategies must be rethought to the extent that it is more effective and able to meet the needs, expectations and aspirations of individuals in their daily lives. In reality, the state of the urban living environment reveals certain practices, emanating both from public decision-makers and from citizens themselves, who express that the urban space management policies adopted are mostly carried out. Outside the regulations. These urban fragilities of the living environment that characterize most Algerian cities, including the city of Ain-Beida, have pushed us to the process of urban diagnosis, through which we aim to assess the standard of living while detecting all gaps and nuisances in order to put an end to the informal urban with its resulting paradoxes. To carry out this work, the methodology adopted to measure this quality is based on the quantitative method which is often carried out via a survey through which we aim to capture the representations of the population as well as its perceptions through a set of themes: the commercial weight, the level of equipment, traffic and transport problems, accessibility to relaxation and meeting areas. The results obtained show that the different sectors of the city face various difficulties. The inhabitants of the central districts and certain pericentral districts express their satisfaction with the potentialities of trade and equipment but they declare the presence of congestion situations and traffic problems. However, the suburbs are devoid of even the basic necessities of commerce and green spaces and recreation, which pushes them to move to other neighborhoods or exit outside the city to meet their needs. However, some residents completely denounce living conditions which do not even meet their basic requirements.
