Purpose of this study is to clarify the formation and development process of the system of architectural agent for procedures required by laws. Conclusion of this study is as follows: 1. Kyoto was the first prefecture which had this ordinance enacted April 1930. 2. Many prefectures had this ordinance enacted especially before and after 1950, when the Kenchikushi Law for Architects & Building Engineers was enacted by the Diet. Eventually, 23 prefectures had it enacted. 3. This ordinance was originally intended to rule architectural agents for procedures required by laws, but from their business experience they began to think themselves of architectural engineers. 4. The trend became more prevalent even after the enactment of the Kenchikushi Law, but the ordinance was curiously repealed with prevalence of the Kenchikushi.
