The purpose of this study is to understand what health and safety hazards low-income households are
subject to by surveying the real conditions of the defective housing of low-income households, and to find
improvement strategies. For this purpose, we visited the concentrated areas of the multi-dwelling unit
(MDU) (also known as multi-family residential) housing in Jungwon-gu and Sujeong-gu in Seongnam City,
Kyunggi-do, one of the representative areas in Korea with a massive distribution of the low-income class.
Based on the survey data, the level of housing defects were comparison analyzed per income decile (decile 1,
decile 2, deciles 3–4), and per housing location, in the categories of subsidence, cracks in the wall,
delamination, water leakage/infiltration, condensation, and contamination. The housing condition per income
class was more defective in the decile 2 households rather than in the decile 2 households, and in the
substructure more than in the superstructure. Among the six defects, contamination problems, caused by
substandard living conditions, were the most frequent cases. Structural defects, subsidence and cracks in the
wall, were found in the main living areas—the bedrooms and the living rooms. It was confirmed in this study
that the conditions of low-income housing are serious, and that it is necessary to explore specific
countermeasures in the near future.
