In this paper, the building maintenance costs for the local government office buildings are analyzed and the cleaning costs especially is clarified. Annual cleaning cost is the same amount of about 40〜60 % of annual energy costs. Next, the actual situation of cleaning management is defined based on the analysis of labor-man hour date of the past cleaning works. With regard to the overall ordered floor area to the cleaning contractors in a year, the ordered floor area for the regular cleaning work is a little. With the labor-man hours for the cleaning works, the regular cleaning works of one on two times in a year exceed the daily cleaning works for some government buildings. With the rooms such as, "Passage and Elevator hall", "Rest room", and "Entry hall", labor-man hours spent for the cleaning works occupies more than half of those of the overall number of daily cleaning work. With the rooms and articles such as, "Office room" and "Lighting equipment", labor -rnan hours spent for the cleaning works occupies more than half of those of the overall number of regular cleaning works. Consequently, in order to reduce cleaning costs, it may be required to focus on the management of these labor-man hours.
