Navigating the void between Decency and Affordability:Housing in Mekelle, Ethiopia

Housing affordability and housing decency are often treated as overlapping concerns in urban housing policy, yet households may occupy housing that appears financially affordable while remaining crowded, poorly serviced or materially inadequate; conversely, they may access better housing only by reducing expenditure on essential non-housing needs. This thesis examines this decency-affordability disconnect in Mekelle City, Ethiopia, through a decencysensitive affordability framework grounded in household composition, local perceptions of acceptable housing and residual non-housing capacity. The study draws primarily on a prewar 2015/16 household survey of renters and mortgage-paying owners in Mekelle, supported by evidence from low-cost condominium housing and the Dingur informal-settlement case. It develops a five-category household lifecycle typology (FA-SD5), applies adult-equivalence adjustment, derives a locally grounded system of Normatively Required Habitable Rooms (NRHR), and constructs a Normative Housing Decency Index (NHDI). It then compares conventional ratio-based affordability with residual-income and normative affordability measures, before integrating housing and non-housing gaps into an affordability-regime framework. The findings show that conventional affordability measures obscure important forms of deprivation. Some households whose observed housing costs fall below the 30 percent threshold still fail to meet minimum decency requirements, while others approach better housing conditions only by constraining residual resources for food, education, health, transport and other needs. Household composition and lifecycle stage shape these outcomes, particularly where larger or later-stage households face simultaneous pressure on space adequacy and non-housing capacity. The case evidence further suggests that formal and informal housing pathways can produce distinct forms of constrained adjustment, including immobility, below-benchmark housing access and structural traps. The thesis contributes to housing theory and policy by conceptualising affordability as a dual-sufficiency condition: housing must be financially attainable and normatively adequate, while also leaving households with sufficient resources for non-housing needs. In policy terms, the study shows the limits of single-threshold affordability measures and offers a diagnostic framework for more context-sensitive housing assessment, targeting and intervention in developing-city contexts.
