Due to a number of influencing factors, construction costs in Kenya range significantly between regions. One important factor is the cost of building materials; areas nearer quarry or manufacturing centers typically have less expensive materials because transportation costs are lower there. Additionally, labor expenses vary, with wages in major locations such as Nairobi and Mombasa being greater than those in rural towns. Foundation needs are influenced by soil type and land topography; rocky or marshy locations demand more sophisticated (and expensive) engineering. Furthermore, the improvement of infrastructure—such as electricity and road access—can raise or decrease logistical costs. Timelines and overall building costs are impacted by county-specific variations in government regulations, levies, and approval procedures.

Climate and weather also matter since regions that experience high levels of precipitation or flooding would need more robust, weatherproof drainage systems and materials. The quality and speed of project execution can be affected by the availability of competent personnel in particular areas, which can affect both cost and time. Speculative land prices and real estate demand also drive increased construction costs in areas that are expanding quickly. Therefore, before starting any residential, commercial, or mixed-use construction project in Kenya, a thorough site investigation and regional cost evaluation are crucial.
