A New Conceptual Framework for Understanding the Contribution of Spatial Planning and Zoning Parameters to Social Justice

Land-use allocations—such as housing density, parcel size, housing typologies, parks, and other green areas—constitute key spatial planning (zoning) parameters that significantly shape how resources and opportunities are distributed within cities. As such, they play a central role in producing or constraining social justice across urban areas and communities, functioning as mechanisms through which planning and development processes deliver—or withhold—critical resources. Yet the literature remains limited in explaining how the allocation of specific zoning parameters contributes to social justice outcomes, which parameters matter most, and which dimensions of social justice they affect. This paper addresses this gap by examining and conceptualizing how spatial planning (zoning) parameters shape social justice in cities. A conceptual review approach, guided by Jabareen’s methodology, is employed to analyze and categorize planning parameters according to their specific contributions to social justice in cities. Accordingly, the study identifies three dimensions of social justice shaped by these parameters—inclusion, accessibility, and recognition—each addressing a key aspect of urban justice. Building on these concepts, we develop a new conceptual framework, referred to as the Conceptual Framework for Just Urbanism. At its core is the logic of difference, which explains how planning parameters are allocated unevenly across geographies, demographic groups, and socioeconomic conditions, producing spatially differentiated inequalities. The study concludes that planning parameters and zoning are powerful carriers of urban justice through their distribution of resources and opportunities.
