One of the primary aims of transit-oriented development (TOD) is to reduce auto dependency, especially for low-income as well as senior residents. This study aims at providing some guiding principles for development of affordable housing with respect to TOD concept. As such, the study employed an index called Affordability Index (AI) and adapted for the study area to assess the neighbourhoods' affordability. It is composed of housing cost, household transportation cost, and household income. The analyses were conducted on three neighbourhoods in Kuala Lumpur, Malaysia. The results reveal that the AI is lower for both owners and renters in the neighbourhood farther away from the LRT station, where there is less public transit facility, despite the existence of more affordable housing. On the contrary, the index is high in the neighbourhood where the distance to LRT station is shorter, connectivity index is higher, and there are more public transport facilities, despite the presence of high- and medium-cost housings. These findings can be used to plan for suitable public transport facilities in view of neighbourhood affordability.
