The purpose of this paper is to clarify the influence of building codes on conversion of closed elementary and junior high schools in depopulated areas. Some results show as follows : (1)In the past, obligatory return of national subsidy for school construction prevented closed schools from conversion, but recently such a situation has been improved by deregulation. (2)In depopulated area, there are a lot of regions where waste water purifier is used. In such a region, installation of combined treatment purifier becomes a question of money. (3)Conversion from the usage with a loose requirement for fire extinguishing equipment to a severe usage needs more advanced fire extinguishing equipments.
