抄録

We consider that some constructive defects of a house should not be avoided in general, because many workers of various kinds of technical fields joint together to build a house. In Japan, dwellers has required the finish in a fine degree as well as the traditional and manual work level, though houses has been built by industrialized construction methods more or less at present. Then the claim for defects in the houses actually has become as one of the social problems. In this paper, We aim to make precisely real situations of defects in Japanese houses, relations between defects and some housing factors, and to find some rules with periodical variation of the appearance of defects. The following conclusions have been obtained as results : (1) The reliability of the dweller's answers about defects of his house is able to be confirmed in high degree by comparing the various estimates for defects by dwellers with inspectors. (2) Some relations are recognized between defects of houses and housing factors, i.e, that the appearance of defects is highest in the ready-built houses for sale and low housing costs, and it shows a tendency for prefabricated houses and apartment houses to decrese by moving into the latest year, which means the progress of industrialized construction methods. (3) A periodical variation and cumulative frequency distributions of the appearance of defects are divided into four patterns, so that they will be a basic index on the occasion of estimating defects qualitatively on a specific house (include a defective house).
