To spread the positive effects of urban renewal, Taipei's Urban Renewal Ordinance stipulates that except in extraordinary cases, for a private urban renewal project to be approved, residents must live on the same street block and the land area must be at least 2000 square meters (around 605 ping).
為了擴大更新效果，「台北市都市更新自治條例」規定，除了特殊例子外，自辦更新案者必須是同一個街廓內，面積在 2000 平方公尺（約 605 坪）以上者才得以申請。
