This study investigates the impact of construction-related risk factors on residential property development in Obio-Akpor Local Government Area (LGA), Port Harcourt, Nigeria. The research primarily seeks to identify the major construction-related risks affecting residential development and examine their effects on the cost, time, and quality performance of residential construction projects. A descriptive survey design was employed to assess the risks, targeting professionals, including estate surveyors and real estate developers in the study area. A sample size of 193 respondents was drawn using stratified random sampling from a target population of 379 professionals. Primary data was collected through structured questionnaires, and secondary data from journals and reports. The validity and reliability of the instrument were ensured, with a Cronbach's Alpha coefficient of 0.82. The study identified inflation and price fluctuations as the most critical risk factor affecting residential property development, followed by delays in approval processes, inadequate project financing, labor shortages, poor site management, insecurity, delays in material delivery, and design errors. The findings indicate that these risks significantly affect project costs, timelines, and quality. Cost overruns, project delays, and compromised quality were identified as the most critical outcomes of these risks. The study recommends addressing these challenges through improved financial management, streamlined regulatory processes, enhanced workforce training, and better security measures. It suggests that policy reforms focusing on increasing access to financing, reducing bureaucratic delays, and mitigating risks such as labor shortages and insecurity are essential for the sustainable development of residential property in Obio-Akpor LGA.
