This paper examines stakeholder engagement and participation in mass housing development projects within Abuja's Public-Private Partnership (PPP) initiatives. Through case studies of prominent projects like Sunnyvale Estate, Garki II District Development, and the Life Camp Extension Project, it aims to explore the multifaceted roles of government agencies, private entities, local communities, residents, and the limited involvement of non-governmental organizations (NGOs) and advocacy groups. Drawing from extensive literature, the study delves into the theoretical underpinnings of stakeholder engagement within the context of Public-Private Partnerships and housing development, emphasizing the importance of transparency, accountability, and social acceptance. Methodologically, the study adopts a qualitative approach, employing case studies and literature review to analyze the extent of stakeholder involvement in Abuja's mass housing projects, with a focus on government agencies, private developers, local communities, residents, and NGOs. Results and discussion underscore the significant roles played by government agencies and private developers in driving housing development projects, while also acknowledging the active participation of local communities and residents. However, the limited involvement of NGOs and advocacy groups poses challenges to achieving inclusive and sustainable housing solutions in Abuja. In conclusion, the paper emphasizes the importance of enhancing stakeholder engagement and participation to address Abuja's housing challenges effectively, advocating for transparency, accountability, and inclusivity in future PPP housing projects. Recommendations include prioritizing community involvement in decision-making processes, adopting socially responsible practices by private developers, and strengthening the role of NGOs and advocacy groups in advocating for housing rights and social equity.
