Abstract
The problems of maintenance and management cost, especially, of repair work cost, posed by Japanese medium- and high-rise condominiums are analyzed here based on the annual financial reports compiled by the management association as of 1989. Chief findings are: (1) The annual average cost per housing site for minor repair (part of maintenance) is 508 yen/m_2・year, chiefly for the adjustment and checking of the laidout equipment. (2) The cost for major repair related to damaged outer walls or water proof reefs is covered by reserved cotributions. (3) The long-range standard and system for securing efficient repair work should be established along with planning the detailed checking list of time.
