The rapid pace of urbanization experienced in most Nigeria cities has contributed immensely to the quantitative and qualitative problem of housing. The sustainability of infrastructure demands an attention. This study aims at assessing building maintenance and infrastructural facilities in Akoko-Edo, Edo State, Nigeria. The data for the study were collected through questionnaires administered to users of residential buildings and the buildings’ owners within Akoko-Edo and construction professionals. One hundred and seventy one (171) questionnaires were distributed using random sampling technique; one hundred and thirty (130) questionnaires were returned and considered suitable for analysis. Descriptive statistical tools of relative importance index and mean item score were employed for the analysis. Findings reveal that all the respondents carry out one form of maintenance activity or the other. Majority of them prefer condition – based maintenance as the most frequently used maintenance class, they also agreed that direct labour organization and in-house labour are the most frequently adopted maintenance practices.
