The performance level of the structural systems of residential buildings is directly related to quality during the design, execution and use phases and, in order to guarantee safety and efficiency in these stages, buildings must present a minimum level of performance, according to the recommendations of the standard of housing performance (ABNT NBR 15575).The research involves qualification of points of nonconformity with the minimum criteria required in NBR 15575/2013 and evaluation of pathologies that affect these buildings.To this end, a questionnaire was applied in five works, in the execution phase, in order to diagnose the knowledge of the builders, with respect to the minimum recommendations and their application in the new projects and, in order to evaluate the pathologies, observed by the technical team of the works.The results indicate a good level of knowledge about the recommendations, only the topics related to the resistance of the elements of reinforced concrete in a fire situation, present indicators below the minimum specifications required.Therefore, it can be concluded that the procedures adopted by the technical teams during the design and execution of housing units indicate a satisfactory basis for the minimum performance of their structural systems.
