Strategies for increasing affordability often involved trade-offs between various goals and impacts. It is important to consider all of these factors when evaluating potential solutions to unaffordability.
Earlier this year, the U.S. Department of Housing and Urban Development devoted an entire issue of a quarterly newsletter to land use regulations and the idea that local laws are strangling the nation's supply of affordable housing.
Some commentators on urban containment treat the issue as all-or-nothing: either strict limits on suburban development are good public policy everywhere, or they are good public policy nowhere. Perhaps a more nuanced view is appropriate.
