Abstract

Cracks, which account for the largest proportion of defect lawsuits in apartment buildings, are not clear on the criteria for defect determination, so judgments about defects are mixed. Interlayer cracks, which account for most of the crack defect judgment amount, tend to be judged as defects regardless of the crack width or condition, and repair methods are mostly set uniformly. This starts from the problem that the standards of the Ministry of Land, Infrastructure and Transport and the Construction Appraisal Practice, which the courts use as standards, do not match. It is necessary to establish a defect determination standard that can be applied to all stakeholders through the amendment of laws and the revision of the Court Appraisal Practice. In addition, it is necessary to apply the crack repair method according to the width and condition of the interlayer crack. If the defect determination and the application of the repair method for cracks are rationalized, it could serve as an opportunity to change the current trend of defect disputes that rely only on litigation.

공동주택의 하자소송 금액에서 가장 많은 비율을 차지하고 있는 균열하자는 하자판정 기준이 명확하지 않아 판결에 따라 하자에 관한 판단이 엇갈리고 있다. 균열하자 판결금액 대부분을 차지하는 층간균열은 균열의 폭이나 상태와 관계없이 모두 하자로 판정되는 추세이며, 보수공법 또한 대부분 일률적으로 정해지고 있다. 이는 균열하자 판정의 기준이 되는 국토교통부의 하자판정기준과 법원에서 기준을 삼는 건설감정실무의 기준이 일치하는 않는 문제에서 출발한다. 법령의 개정과 법원감정실무지침서의 개정 등을 통해 모든 이해관계자가 적용할 수 있는 하자판정 기준의 수립이 필요하다. 또한, 층간균열 보수공법 기준은 층간균열의 폭과 상태에 따라 공법을 적용할 필요성이 있다. 균열에 대한 하자판정과 보수공법적용을 합리화한다면 소송에만 의존하는 현재의 하자분쟁 추세를 바꿀 수 있는 계기가 될 수 있을 것이다.
