Despite different approaches to economic growth over the years, inadequate distribution of resources has continued in Kenya. As part of measures to address this, the government adopted decentralized development by establishing the Constituency Development Fund (CDF). However, queries have been raised over effectiveness of the CDF projects on community welfare of which this study sought to evaluate. The study was anchored on decentralization theory and adopted descriptive cross sectional survey with a sample of 383 respondents from a target population of 94,637. The study was guided by two objectives: to identify and describe CDF projects addressing community welfare; and to examine the effect of selected CDF projects on community welfare. Questionnaires and interviews were used to collect primary data which were both qualitative and quantitative. Quantitative data from the sample was first analyzed using descriptive statistics mainly percentages. Pearson Chi-square test (χ2), Spearman’s Correlation and Symmetric Measure Gamma statistic were used to infer from sample to population to test statistically significant relationships. Content analyses have been used for qualitative data. The study established that a diversity of projects are funded by CDF but education, health and water/sanitation are the key CDF projects addressing community welfare and have strong and significant influence. CDF projects vary as per the immediate need of the community.
