Industrial vacancy rates in August 2009 ranged between 8% and 21% across the 50 major US metropolitan markets, covered by data provided by NAR/TWR.
Vacancy rates are significant indicators of the prevailing demand-supply balance in the local industrial market. Very low vacancy rates tend to reflect very little or no excess supply of industrial space in the local market, while the risk of oversupply is considerably greater in markets with high vacancy rates. Within this context, when evaluating metropolitan industrial markets for investment targeting puproses, vacancy rates provide important summary information regarding relative market tightness.
Los Angeles was the industrial market with the lowest vacancy rate of 8.2%, in August 2009, according to the data provided by NAR/TWR. The next four industrial markets with the lowest vacancy rate are Houston, Kansas City, Long Island and Las Vegas, with the first three posting an average vacancy of 9.7% and the last one posting an average vacancy rate of 9.8%.
