Abstract
In this paper, the author defined the actual conditions of the architectural organization on the local authority, Fukuoka prefecture, especially the feature of two sector; one had a function relating to building and repairing, and the other to supervising the building law, before the last war. The results of research are as follows ; the former sector had belonged to the civil engineering section and needed a long term to establish architectural organization, and the latter sector had an early chance of independence, because of supervising the building law. As two sectors were independent each other, the staff exchange between two sectors had not existed. The actual number of staff on both sectors had differed from the number which were regulated by the local authority law.
