A Study on the Determinants of the Apartment Common Area Usage Fee Considering the Contract Type of Electricity Charge

Of the various factors consisting apartment maintenance costs, common area usage fees can be affected by the electricity supply contract, and whether it is a comprehensive or single contract. Thus, it is necessary to consider selection bias in accordance with the contracts. However, previous studies regarding maintenance costs have only examined large categories of common usage fees. Thus, this study conducted empirical analysis using Sample Selection Models with the 955 apartment complexes data in Suwon, Seongnam, and Yongin obtained from the K-apt in 2019. The results showed that the apartment complexes’ characteristics (i.e. ratio of exclusive use area, number of parking lot per households, and ratio of underground parking lots) have significant impact on common area usage fees. Also, in case of rental housing complexes, common area usage fees were relatively low. Second, facility characteristics such as the number of elevators and availability of home network systems per household were derived as factors that increase common area usage fees. Third, regarding regional characteristics, results showed that common area usage fees in Suwon and Seongnam were relatively high.
