This study assessed the locational characteristics of filling stations in Osogbo, Nigeria. Multi-stage sampling technique was employed for the study. Three residential zones: the core, transition and suburban zones were identified, 121 filling stations were identified across the 3 residential zones, these comprised 46, 61 and 14 in the core, transition and suburban zones respectively. In each zone, 1 out of every 10 filling stations were selected, thus, 5, 7 and 2 filling stations in the core, transition and suburban zones making a total of 14 filling stations were selected. In selecting the sampled residents, buildings within 500 metres radius to each selected filling station were surveyed. A total of 3,056 residential buildings were identified. Using systematic random technique, 10% of the total numbers of buildings were sampled resulting in the selection of 311 residents for questionnaire administration. The data collected include coordinates of the facilities using the Global Positioning System (GPS). GIS was used to spatially locate the filling stations on digitized Google Earth Thematic map of Osogbo, also, the Nearest Neighbour Analysis was adopted in the analysis to establish the spatial spread of filling stations in the residential zones of Osogbo. The findings revealed a geographical spread of filling stations across the different residential areas of Osogbo. The study also revealed that the distribution of filling stations in the core, transition and suburban areas of Osogbo were highly clustered which is an indication that planning standards are not strictly adhered to when siting filling stations.
