This webinar reports findings from a NITC study which assessed the affordability of HUD rental assistance properties from the standpoint of transportation costs. HUD housing is, by definition, affordable from the standpoint of housing costs; there are limits on the amounts renters can be required to pay. However, there are no such limitations on transportation costs, and common sense suggests that renters in remote locations may be forced to pay more than 15 percent of income, a nominal affordability standard, for transportation costs.

Using household travel models estimated with data from 15 diverse regions around the U.S., researchers estimated and summed automobile capital costs, automobile operating costs, and transit fare costs for households at more than 18,000 HUD rental assistance properties. The mean percentage of income expended on transportation is 15 percent for households at the high end of the eligible income scale. However, in highly sprawling metropolitan areas, and in suburban areas of more compact metropolitan areas, much higher percentages of households exceed the 15 percent threshold....

Edged Out: Location Efficient Housing and Low Income Households in the Portland Region

Transportation costs are typically a household’s second largest expense after housing. Low income households are especially burdened by transportation costs, with low income households spending up to two times as much of their income on transportation than higher income households (Litman, 2013).

Thus, access to location efficient housing is especially important to...

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? This study examines housing costs for households living in TODs.


  • Learn how many TODs there are currently in the U.S. and what methodology was used to identify them.
  • Learn what share of housing in TODs is affordable, what are the relative shares of designated versus naturally occurring affordable units and whether the level of affordability is the same for families of different sizes.
  • Learn ...
