More than half of the world's population of over six billion people reside in urban areas, placing increasing responsibility on governments to provide fundamental human necessities, including housing. This challenge is particularly pronounced in Kenya, where many County Government PPP affordable housing initiatives have either failed or been stalled. Both National and County Governments have experienced difficulties in executing these projects, reflecting the nascent stage of PPP application in many underprivileged countries. In Meru County, the Affordable Housing Project (AHP) employs PPP, primarily in the form of joint ventures. This approach distinguishes it from other existing projects and generates a knowledge gap regarding the assessment of the impact of public-private partnerships on the implementation of affordable housing initiatives in this region. The aim of this research was to explore the effects of stakeholder’s management in public private partnership on implementation of affordable housing projects in Meru County, Kenya. Guided by stakeholder theory, the study employed a descriptive research design, collecting data through a structured questionnaire. A proportionate stratified random sampling method was used to select the study sample from County officials, non-governmental organization managers, development partners' managers, and household heads from selected study areas where the projects have been initiated, notably in the Buri, Maweni, Mjini, and Makandara wards. A total of 395 questionnaires were issued to the sampled respondents from a total target of 31978 who included the stakeholders in affordable housing project estates in Meru County that included county official managers in DoLPH (15), NGO’s managers (25), development partners’ managers (5) engaged in affordable housing and household heads (350). The collected data was analyzed and results presented in tables and figures, the qualitative information was presented in prose.
