Find Your Market Area

  • Market areas are groups of neighborhoods within the county that have similar trends in the market. For example, sales and resales within a market area will reflect similar influences, such as areas with higher foreclosure activity or areas where the market has remained stable. In Boulder County, we use market areas in establishing market trends for mass appraisal purposes.

Your market area number is listed on your Notice of Valuation on the lower left side of the page below your property address and account number.
