The Moon administration is currently pushing for a policy to select 100 new cities annually for Urban Regeneration New Deal project. As the government is showing a strong will towards urban regeneration, there has been growing interest in urban regeneration nationwide. As the interest in urban regeneration grows, there is a heightening awareness that vacant houses in declining areas can be used as local resources that can be used differently from before. At this point, the case of Gunsan City’s urban regeneration leading district, which was carried out using vacant houses and stores in the region, provides significant implications. Especially, it is considered that Urban Regeneration Support Center, the mediating organization, took an important role in this project. From the case of Urban Regeneration Support Center in Gunsan that used vacant houses and stores, the following implications can be drawn. First, the urban regeneration project should play a mediating role between landlord and tenant. It is necessary to coordinate opinions between landlord and tenant. Through mediation, landlords should be asked to charge lower rent compared to the surrounding area and tenants should pay proper rent. Second, it should constantly serve the role of a manager. It is necessary to provide support not only in connecting landlord and tenant during the contract process but to offer support for difficulties in the process of moving in and to provide management consulting. Third, the project should pay attention to publicity along with the development of the region. Instead of emphasizing only the development of the region, it should also care about the restoration of communities and sharing of profits when implementing the project. Currently, local governments are increasingly interested in using vacant houses and stores in declining areas in order to promote the Urban Regeneration New Deal project. In addition, there are many studies and efforts on the continuously increasing use of vacant houses and stores. At this point, this study is significant in that it introduces the case of Gunsan city and draws implications. It is expected that with the continuous implementation of the Urban Regeneration New Deal project, a model based on various cases of vacant houses and stores will be established.
