Fire services are important as they are to save lives and properties. However, there are few studies in developing countries on the effect of poor roads condition on fire service delivery. Thus this study, therefore examines the optimality in location and the effect of road conditions on the response time of fire service in the Ogun West Senatorial District, Nigeria. The concepts of the central place theory provided the theoretical background for this study and they are operationalized by models of the location-allocation (L-A) methods. The data for the L-A models in the study are the coordinates of the locations of the 509 settlements and the four fire stations, as well as the road network in the study area. The result of analysis from the study revealed that the fire service mean response time can be reduced by 61.62 % from 18.97 minutes in the existing locational configuration of fire stations and on the existing condition of roads to 11.69 minutes if the locations are optimal and all roads are good. This study showed that fire service response time can be reduced in a given region if the locations of fire stations are carefully planned and the roads in the region are good.
