In 2002, the National Property Bureau began to conduct audits of 10,701 state-owned houses in Taiwan. At the end of the following year, the audit revealed that unused or "low-use" (under 50 % occupancy) units amounted to 76 % of the whole. The overwhelming majority was made up of Japanese houses. In Taipei alone there were more than 1,200 of them.
國有財產局自 2002 年開始，對於全省總共 1 萬 0701 棟公有房舍展開清查，隔年年底的清查結果發現，閒置或容積率低於二分之一的「低度使用」者高達 76％，其中絕大多數都是日式宿舍，光在台北市就有超出 1200 棟。
