Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change?

Is Transit-Oriented Development Affordable for Low and Moderate Income Households?, a study funded by the National Institute of Transportation and Communities (NITC), examines housing costs for households living in TODs. Led by Reid Ewing of the University of Utah with co-investigators Nicole Iroz-Elardo and Arlie Adkins of the University of Arizona, the team examined the housing affordability of TODs in U.S. cities across 23 regions. The analysis of housing costs revealed a lot of variability across different regions. Of all the examined housing developments, only 16 projects/developments out of 117 across 85 TOD sites were deemed 100% “affordable” – meaning that all the units in those 16 developments were affordable to households earning up to 80% of the average median income for that county.
