The Library used to be the place to look up property assessments. Now property owners can look up their own assessments online, with the County Data Search.

In a January 14, 2011 press release, Arlington County reports:

Arlington’s 2011 real estate assessments are up 6.3% overall, nearly erasing last year’s decline of 7.2%. The commercial sector, including office and apartment properties, showed particular strength, gaining 12% and nearly recouping last year’s decline of almost 13%.
