The purpose of affordable housing is to make quality, safe, affordable housing available for low and middle-income households. Rapid urbanization, rising population and the growing housing shortage has positioned affordable housing as a national priority in Kenya through the Affordable Housing Programme and the Big Four Agenda. But the challenges in implementation of affordable housing projects still remain like under allocation of resources, weak governance system, ineffective stakeholder participation and ineffective risk management practices etc. The study examined the impact of strategic decision-making strategies on the implementation of affordable housing projects in Kenya, with the Pangani Affordable Housing Project as a case study. The study employed a descriptive-correlational research design with the participation of 100 respondents to the project. Structured questionnaires were used to collect data which were then analyzed using SPSS version 27. The results showed that the variables of resource allocation (beta = 0.276; p<0.005), risk management practices (β = 0.188; p=0.008), stakeholder engagement (β = 0.313; p<0.005) and governance practices (β = 0.277; p<0.005) significantly positively affected project implementation. Stakeholder engagement proved to be the most successful predictor of successful implementation. The study finds that projects in Kenya's affordable housing market are more likely to be successful and sustainable when they utilize resources effectively, engage stakeholders in a participatory way, adopt a proactive approach to risk management, and are well-managed by transparent governance structures.
