The study intended to examine how project management triple constraints and performance of affordable housing program in Kenya. Specifically, the study aimed to examine how project scope management and moderating influence of community participation influence affordable housing program in Kenya. The study was based on the theory of triple constraints. The study adopted descriptive research design. The target population of this study was 24,000 housing units project under the affordable housing program in Kenya. The study used simple random sampling to select 393 project managers from the target population. This study used both primary and secondary data. Secondary data was obtained from annual reports under affordable housing program. The study used semi-structured questionnaires to collect data. A pilot test was conducted to test the reliability and validity of the data collection instruments. Quantitative data was generated from the closed ended questions and qualitative data was obtained from open ended questions. Thematic analysis was used to analyze qualitative data and presentation of results was in a prose form. Statistical Package for Social Sciences (SPSS version 24) was used to analyze all quantitative data. Inferential and descriptive statistics were used to analyze qualitative data. Frequency distribution, mean (measure of dispersion), standard deviation (measure of dispersion) and percentages were inclusive in descriptive statistics. Inferential data analyses were done using Pearson correlation coefficient, regression analysis. The hypotheses were tested at 5% level of significance. The study results were presented in tables and graphs. Qualitative data was interpreted by attaching significance to themes and patterns observed by the use of content analysis. The study found that: project scope management significantly influences performance of affordable housing program in Kenya. The study further established that community participation has moderating influence on the relationship between project management triple constraints and performance of affordable housing program in Kenya. The project scope can be improved by setting clear goals and objectives. The goals should have the proposed idea and then define the objectives that will guide the achievement of the set goal. The challenge of unrealistic deadlines can be resolved be having an open communication with the clients to determine whether there are other factors that drive the project deadline.

Key Words: project management triple constraints, affordable housing program, project scope management, community participation
