The diversity in perspectives on informality is the starting point of the present article, which presents an everyday sociological point of view of this phenomenon. In this sense, it exposes the transition of informality from a problem-like reading, towards its understanding as the space for the construction of social life, through the examination of this phenomenon’s manifestations in the context of informal commerce. It proposes an approach to the every day practices of individual and collective actors, as well as the theoretical construction of the concept by exploring its course in the academic field in order to achieve a conceptualization that contributes to the formulation of urban public policies. The present article is a contribution from the urban, political, and legal sociology that encourages the generation of complex perspectives on informality within the academy as well as in the public administration area.
