The general objective of the study was to assess how land-use planning can be effectively used to enhance socio-economic development in the Sunyani Municipality and Odumasi. It is based on the aforementioned that this research was designed to identify some of the inherent problems associated with land use planning and how it has impacted on socio-economic development in both Sunyani Municipal and Sunyani West District Assemblies in the Brong Ahafo Region of Ghana. Sunyani Municipality has several layouts but for the purpose of this study the sectors 2, 3 and 4 were purposely selected as these areas are high class residential and well planned communities in the Sunyani Municipality. In Odumasi sector 9 was purposely selected. All these sectors gave a total of 3516 (Sunyani, 3116 and Odumasi, 400). 84 landlords were interviewed in Sunuyani Municipality and 40 landlords were interviewed in Odumasi. . The study indicated that all the landlords interviewed had an approved site plan which was prepared from a planning scheme. The nature of land ownership can delay land use planning process as there are some cases of litigation over who owns land and has the right to sell land. The Assemblies could not effectively control physical developments as they were constrained by inadequate logistics and personnel. 55 percent of landlords in Odumasi did not have building permits. In response to these findings this recommendation among others were made: The District/Municipal Assembly in the study area should resource the Development Control Unit in terms of logistics to effectively monitor all forms of physical development.
