Peoples lifestyles are diversifying due to an increase in the types of residents housing and family structures. The ratio of apartment housing in Korea was 59.9% (9806 households) in 2015, and this type accounts for the largest ratio among all housing types. However, the life of the physical housing is approximately 30–40 years, which is relatively shorter in comparison to that of overseas houses. Therefore, the certification system for long-life housing, which had longer social and physical service life, was newly established in 24 December 2014. However, all apartment houses only acquired the normal grade (grade 4).

The total number of certification cases was 283, and the data analysis and FGI (Focus Group Interview) investigation method were used as the methods of study. As a result of analysis and summary, 173 cases (61.13%) received 50 points and 106 cases (37.46%) received 51 points. All these cases were considered normal grade. The result of this study is as follows. First, a system to maintain the long-life housing certification system operation agency is necessary. Second, the reason for an item with no score was the evasion by construction companies due to an increase in both the construction expense and sale price.

Third, it is necessary to improve the detailed evaluation standards of the certification system and reexamine its scoring system. Long-life housing is a housing type in preparation for changes in the residential environment in future.
