When you add in the facts that Tainan has been under less development pressure than other cities in Taiwan (economic development having long been centered in other locales), and that land in Tainan is zoned into very small plots, often long and narrow, unsuitable for redevelopment by commercial builders, you can see why there are so many unused old houses waiting to be rented, renovated, and reused.
古都基金會執行長張玉璜進一步分析：「由於府城土地分割面積小、形狀狹長，一般建商很難介入更新，再加上台南相較台灣其他都會，開發壓力較緩，以致閒置老屋眾多，給予私人承租再利用、甚至打造新風貌的機會。」
