This article critically examines the principles for assessing the quality and sustainability of social housing architecture projects, using the Mucajá Housing Complex, located in Macapá, Amapá, as a case study. Through a qualitative research methodology, including document, design, bibliographic, and photographic analysis, the physical and environmental aspects of the housing complex will be evaluated. The article identifies how the principles of flexibility, functionality, accessibility, and the sustainable use of natural resources were incorporated into the Mucajá project, analyzing its ability to meet the present and future needs of the residents, as well as its contribution to environmental preservation. The results indicate that the Mucajá Housing Complex does not satisfactorily meet most of the Principles of Sustainability and Quality in Housing Project Design. It highlights the complete absence of verifiers that meet the Principle of Sustainable Use of Natural Resources and the Principle of Flexibility, as well as the high inaccessibility of the Complex. This demonstrates that the housing complex is disconnected from most sustainability indicators.
