Vertical movements in most residential storey buildings in urban areas in developing countries are made using reinforced concrete stairs. However, there seem to be movement difficulties owing to poorly designed and constructed staircases. The objective of this study is to determine the existence and extent of differential measurements (DMs) in stair construction and their effects on building users. Using 120 residential storey buildings selected by purposive sampling in ten sub metropolitan districts in the Greater Kumasi area, the study adopted survey questionnaires, observations, and physical measurements of stairs to collect data. The study revealed that differential measurements in stair construction and associated problems exist in residential storey buildings. Its awareness level is low owing to the low number of publications on the health impact of building units in the country and the occupancy evaluation of existing buildings. We noted that professional bodies and other educational institutions should develop a complete guide/manual on the construction of residential storey stairs and agreeable standards for construction works for the Ghanaian construction industry. Further, it is recommended that on-site training for carpenters/joiners on the construction/erection of formwork for stairs and masons on working on and around stairs/staircase areas must be employed to avoid DMs on stairs.
