From Robert Whitcomb’s “Digital Diary,’’ in GoLocal24.com

There’s a very useful article by Aaron Renn in Governing Magazine about how “poor neighborhoods” with lots of owner-occupied dwellings provided a springboard for people to enter the middle class. It sure beats massive, impersonal and often crime-ridden public-housing projects. An example would be those New England neighborhoods of “three-deckers” in places like South Boston. The owners often live on just one floor and rent out the rest of the building – a way to start gaining middle-class wealth.

But, as I’ve noticed in the U.S. cities where I’ve lived – Boston, New York, Philadelphia and Providence – public policies and changing social attitudes have eroded the benefits of this “starter housing’’ for years. Among Mr. Renn’s observations:

“The rise of zoning and ever-stricter building codes … played a role, especially in recent years, preventing the construction of traditional starter neighborhoods.”

“Changing zoning regulations to create more affordable neighborhoods in some of America’s most expensive cities would help establish platforms for upward mobility. …{But} other factors played into making these old neighborhoods what they were. They were high in social capital, characterized by intact married families, and populated with people who possessed the skills needed for building maintenance. These exist today in some immigrant communities, but less so in society at large.’’

(Ah yes, the collapse of marriage and the stability that went with it.)

Policy makers take note, particularly considering a housing-cost crisis that shows few signs of abating.
