A comparative analysis of housing quality rating systems: Insights for contextual adaptation and policy development

Housing quality has emerged as a central concern amid growing pressures from urbanization, sustainability imperatives and post-disaster reconstruction. While many sophisticated rating systems were developed to evaluate housing performance, their design and applicability remain poorly understood in contexts with divergent regulatory, institutional and market conditions. This study conducts a comparative analysis of eight internationally recognized housing quality rating systems, guided by an original framework encompassing seven content and procedural dimensions. Through qualitative coding and cross-system synthesis, the research identifies three functional categories, systems that enforce minimum standards, define housing quality across a graded spectrum or facilitate management practices. The analysis reveals that these categories reflect underlying institutional logics, with each system's effectiveness shaped not only by its technical content but by its alignment with regulatory authority, market incentives and organizational capacity. Rather than supporting direct adoption, the findings emphasize the need for tailored frameworks that respond to local priorities and constraints. Furthermore, the study outlines key operational considerations, such as criteria localization, enforcement infrastructure and evaluation timing, that affect system transferability. Together, these insights provide a foundation for developing housing quality systems that are context-sensitive and institutionally grounded, offering practical guidance for reform and policy adaptation in diverse housing environments.
