Though the nation is starved for new inventory, most new building permits were authorized more than a decade ago.
HousingWire reports that the National Association of Realtors compared building permits from 2000, 2005, and 2015, and created a map that shows when counties across the U.S. authorized the most permits.
According to the data, 60 percent of counties peaked in building permits in 2005, compared to 28 percent in 2000 and 12 percent in 2015. Washington D.C. and North Dakota were among the few places that peaked in 2015.
Also, the U.S. Census Bureau created a tool that compares how many building permits were authorized for each county to how many were needed.
For example, in San Francisco, 2,996 new housing units were needed to meet the need for new homes on the market, and 3,665 new units were authorized by building permits in 2015. In Dallas, the need was much higher at 15,558 new units, but 21,698 new housing units were authorized.
