How information asymmetries exacerbate building defects risks for purchasers of Australian residential multi-owned properties

Abstract

ABSTRACT Increasing urbanization is driving rapid growth in residential multi-owned properties (RMOPs) worldwide. Concerns about the quality of these buildings are also growing in many countries. Yet research into the quality of RMOPs (particularly apartments) remains scant and under-theorized. Addressing this knowledge gap, this paper reports the results of research which employed information asymmetry theory to provide new insights into the prevalence and risks of building defects in the Australian RMOP construction market. Using data about defects in 635 RMOPs built in Sydney between 2008 and 2017 and semi-structured interviews with sixty-six experienced practitioners, the results highlight the severity of the defects crisis. The research identified two types of information asymmetries which exacerbate the risk of buying into a defective building for RMOP customers: data fragmentation and data robustness. From a policy and practical perspective, this highlights the challenges faced by consumers in undertaking ‘due diligence’ and the need for reforms that address these information asymmetries.
