Affordability and accessibility of condominium housing in urban Ethiopia using a combined transportation and housing cost (CHT) index model: implication for sustainable urban infrastructure, policy and development

Condominium housing is a critical housing option, but its affordability measures continue to be debatable. This study examined the mutual effect of housing & transportation monthly expenses on housing location affordability and accessibility, considering three comparable locations- inner-city, intermediate, and outer-city condominium locations in Addis Ababa, Ethiopia. 1152 condominium residents were surveyed to assess urban housing location affordability using the combined H+T affordability index, GIS, one-way ANOVA, and Logit model. Housing affordability is diversified in the city, distance to CBD & transport are significant factor. Outer-city and intermediate neighbourhoods are unaffordable & inaccessible, with 55% and 48% index, respectively. Outer-city residents and lower-incomers face higher financial burdens. Nevertheless, inner-city is affordable & accessible, and residents enjoy better proximity to services. It contributes insights to enhance literature and debates on the model. H+T index provides up-to-date understanding and informs policymaking for innovative, smart, and sustainable, location-sensitive, integrated, and pro-poor policies.
