Abstract
In order to raise the safety of an apartment, the improvement in capability of the person in charge of a construction check organization should be measured. Tightening up penal regulations is unavoidable at the same time. Four structural calculation standards of the Building Standard Law need to have consistency. For the buyer protection, it is not appropriate to concentrate the responsibility on a municipal corporation. It is required to solve in the process of construction and dealing, and the seller takes out an insurance policy compulsorily for that purpose. The buyer should admit paying the expense.
