The Han family compound is located in Shangli ancient town in the Sichuan province and is a well-preserved building complex of the Qing Dynasty in the ancient town. In 2005, in order to develop tourism, the government began using part of the courtyard as a museum; however, due to financial and human resources, the museum was closed, and the Han family compound fell into a dilapidated condition. In this paper, through a field survey, we found that the Han family compound has three compounds, the third of which has been abandoned, while the second compound has been developed by the Han family's descendants as a bed and breakfast, and the first compound has been left unattended by the government due to the right to use it. Through interviews with local visitor centers, village committees, and original Han family compound occupiers, we learned that the Han family compound is facing a difficult maintenance situation due to a lack of attention, unclear boundaries of authority and responsibility, a lack of available technical and financial support, and lack of professional restoration personnel. Therefore, we have to consider the problem of ancient building maintenance and protection. This paper briefly analyzes the current conservation concept of ancient building maintenance, and draws on excellent cases of ancient building maintenance at home and abroad to summarize the corresponding strategies to enhance the ideology of residents' maintenance and protection, use the conservation strategies of IPOGEA and ITKI, and give modern functions to ancient buildings in order to achieve the goals of building maintenance and protection and the sustainable development of the Han family compound. The aim of this study is to provide some reference for the conservation and development of similar architectural heritage.
