The apartment management market has been expanding as apartments have become a representative type of housing in South Korea. Recently, the government has been trying to construct and disseminate the management system through the discussion about efficient apartment management. In the paradigm shift in apartment management, the management method has an important effect on management efficiency. This study analyzed the factors affecting the management method of 1,595 apartment complexes located in Seoul as of 2015. The main results of this study are summarized as follows. First, it was found that the apartment complex characteristics, such as the type of apartment complex (residential only vs. multi-use apartment complex), the size of the apartment complex, the proportion of the exclusive area to the total complex area, the number of parking spaces per dwelling unit, the size of the exclusive area per dwelling unit, the age of the building, and the brand of apartment complex, directly affect the decision of the management method. Second, it was confirmed that there are significant differences in the facility and equipment characteristics, such as community service facilities, the number of elevators per dwelling unit, the number of CCTVs per dwelling unit, and the home network systems, in determining the management method. Third, the results of this study show that management characteristics like the comprehensive contract type of the electricity charges have different impacts on the management method.
