This study conducted a management system and business analysis related to urban and architecture in local small and medium cities. The current status of the management department of the master plans, which were established based on the laws related to the spatial environment and implemented projects based on them, was analyzed, and the problems were derived. The basic urban master plan of the local government is classified as a hierarchical higher plan than other plans established within the same city, but there was a problem in that the timing of each plan was different. As a problem, the contents of the sub-plan were not included in the upper plan, or the opposite phenomenon occurred. In addition, the management entity of the master plan and sub-projects was different. To solve this problem, it is necessary to form a consistent structure of systematic planning and management subjects. In addition, in the future planning stage, it is necessary to establish a master plan establishment system according to hierarchies. This study is meaningful in that it can be used to establish a master plan establishment system according to hierarchy in the future planning stage and to establish the same management entity as the master plan in the projects stage.
