The implementation and enforcement of the Building Code Standards Structural Provisions for mid-rise residential Buildings in Nigeria have caused severe consequences regarding structural building collapse in the development of mid-rise residential building projects. This is as a result of poor level of implementation, enforcement, and compliance and the key factors and causal factors that impede and impact risks on consumers the development of the industry and the professional practice. This research identifies and examines the failures within the research context framework (Technical, Legal, administrative and Sociological) for mid-rise residential building projects through quantitative and qualitative research analyses. And data were collected through the administration of paper-based questionnaires, semi-structured face-to-face interviews, site case measurement of mid-rise building developmental projects, and focus group discussion which were structured around the key factors, causal factors, and the impact risks associated with the implementation's development, professional practice and consumers. This targets professionals and other relevant stakeholders, key staff of the companies, and mid-rise residential building development projects. Using SPSS for quantitative analysis and NiVivo 10 software as the basis for qualitative analysis, the findings reveal that the administrative related failure was the most influential in leading to Poor-implementation, enforcement, and compliance with building code standards and regulations in mid-rise residential projects, followed by the technical failure and to a lesser extent sociological factor, together with a new exploratory approach to enhance compliance. In view of these findings, this research highlight the need to develop a credible, and acceptable best practices for building enforcement control to improve administrative failure, technical failure, and sociological failure aspects of building code standards and regulatory compliance within mid-rise residential development projects in Nigeria, which should encompass monitoring, the continual review of compliance, and training for capacity development for positive social impact.
