The situation is aggravated by the fact that some building codes do not take into consideration different usage requirements. Regulations state that fire walls must be erected to subdivide areas into units no larger than 1500 square meters, or 2250 square meters, depending on the circumstances.
而建築法中，不考慮使用需求，一律強制適用一千五百平方公尺或二千二百五十平方公尺設一個防火區劃的規定，也不合理。
