Real Property

  System Upgrade Underway

NOTE: All assessment and property tax systems will be undergoing an upgrade beginning August 28, 2020, and may not reflect the most recent data. Please contact 311 if you need immediate assistance.

The Assessment Division's Real Property Section determines values for Denver's residential and commercial real estate. Under the direct supervision of the Deputy Assessor/Chief Appraiser, the Section is organized into five teams:

  • Attached Housing values Condominiums, Townhouses and Row Houses;
  • Commercial & Industrial values all Non-residential Properties except land;
  • High Density values Land, Multifamily Dwellings and Apartments;
  • Residential East values Single Family Detached Houses located East of Colorado Blvd; and
  • Residential West values Single Family Detached Houses West of Colorado Blvd.

Depending on the type of property, appraisers use the cost, market, and/or income approaches to value with certain limitations. For example, the Colorado Constitution Taxpayer Bill of Rights (TABOR) amendment, which was approved by voters in 1992, requires all assessors to use ONLY the market (or direct sales comparison) approach in valuing residential property. For commercial real property, the capitalization of net income approach to value is generally the appropriate method.

By May 1 each year, Notices of Valuation are sent to real property taxpayers whose values have changed since the prior year. If this value appears incorrect, the taxpayer may protest the assessment. Protest instructions are included with the Notice of Valuation.

Denver Property Appraisals
Under Colorado law, all counties must reappraise real property every two years. Results are released in odd-numbered years (2015, 2017, etc).

Tax Rates are set in December each year by taxing authorities like the City and County of Denver, Denver Public Schools and others listed on the tax bill. For more information regarding how tax rates are determined, contact the taxing authorities directly.
