A new report from the Metropolitan Area Planning Council studied the challenge families with children have finding housing, in Newton and across Greater Boston. (Boston Globe story here.)

Part if the issue is simply lack of inventory, especially in communities like Newton where “empty nesters are staying in their family homes long after they no longer need all those bedrooms.”  But it’s more complicated than just that….

….families face stiff competition from roommate households, who occupy more than a third of large rental units. With the combined incomes of multiple adults, roommate households can pay, on average, $450 more in monthly rent than the average family in a large unit. This makes it easy for roommates to outbid families for the available homes. We also find that most roommates have few other options: fewer than one in ten roommates could afford the median priced one-bedroom unit in the area. It also seems that the problem is getting worse; the lack of affordable smaller options has pushed more younger householders into roommate households since 2000, increasing competition for the limited supply of large units.

These results shed light on a topic of great concern to many people around the region, and demonstrate there is no one cause, and no one solution, to the lack of family housing in Greater Boston. The challenges facing families are symptomatic of the region’s broader housing crisis resulting from the underproduction of housing of all types, at many price points, across all communities. The needs of families cannot be addressed in isolation, but require comprehensive action to produce more housing to meet the needs of all the region’s residents today, and tomorrow.
