The purpose of this study examine the defect management of Apartment by analyzing the consciousness on defect management based on various characteristics of residents through surveys of the defects of apartment recently in use and compare them with previous studies and examine them.

The construction defect that occurs repeatedly for a long time in the construction company A is the type of construction which is the most important type of crack on the building, and it is often caused by wood floor, the outer concrete wall, the bathroom ceiling, and the balcony ceiling.
In addition, the repair cost and many number of defects were high in the order of dew condensation, tile construction, facility piping, civil engineering work, flooring work, waterproofing work, and furniture construction.
We were able to analyze the difference in consciousness about the defect management of various customers through questionnaire survey on consciousness difference according to resident characteristics.
For residents’ of Apartment, the consciousness of defect management was divided into nine characteristics: gender, age, family composition number, house size, floor of residents, residence type, residential area, number of households, and building plan type. The survey showed that the 758 people were less satisfied with the high proportion of the population, and the satisfaction was disadvantageous in the real responsibility for the defect, and irrelevant to the residential area, the number of residents.

By establishing strategies for materials and construction methods that require improvement, there is a difference between actual occurrence and customer experience, and we need to establish countermeasures against defects in repetitive and concrete structure cracks, dew condensations, wall tiles, facilities, civil engineering, waterproofing, and furniture construction, and to improve the quality of our customers.
