Did a housing shortage, not overbuilding, drive the housing bubble?
Core argument: From 1996 to 2005, Closed Access cities including New York, Los Angeles, Boston, and San Francisco issued fewer than 2.6 housing permits per 100 residents, versus a national average of 6.5, as regulatory constraints limited new construction.
During the Great Housing Bubble, the U.S. faced a housing shortage, particularly in Closed Access cities like NYC, LA, Boston, and SF, where regulatory constraints limited new construction. From 1996 to 2005, these cities issued fewer than 2.6 housing permits per 100 residents, compared to a national average of 6.5. Despite rising incomes, residents in these cities spent an increasing portion on rent, driving prices higher. The shortage led to mass migration to Contagion cities like Phoenix, which struggled to meet demand despite a 50% increase in building permits from 2001 to 2004. The housing bubble was not due to overbuilding but rather a lack of supply in key areas, causing prices to rise sharply. This undersupply persisted even as housing starts collapsed before the financial crisis, highlighting a fundamental mismatch between housing availability and demand.
