Factors influencing defects in residential buildings

Building defects can lead to several issues, including financial burden, personal safety, and illness. This study investigated the factors influencing defects in residential buildings (FDRBs). A total of 56 articles were found after conducting a systematic literature review (SLR) using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) review method. The gathered documents were used to identify and categorize the factors influencing building defects. Twenty-nine variables were produced through three main factors—technical, human, and environmental. The findings indicated that technical factors have a greater influence than human and environmental factors. The key variables influencing the defects were poor maintenance, poor workmanship, and a faulty design. This study recommends conducting control programs throughout the project cycle to minimize or prevent numerous defects. The study findings could better understand owners and contractors on defects-related issues and assist practitioners in the future to reduce defects.
