Assessment Process

The Assessor is responsible for listing, classifying, and valuing all property in the county in accordance with state laws. Colorado law is very specific in establishing how Assessors value property:

  • Real property must be revalued every odd numbered year
  • The actual value of real property is based on its value as of the appraisal date, which is the June 30th of the year prior to the reappraisal year
  • Residential property may be valued using only the market approach to value. In this approach the value of the subject property is based on an analysis of comparable sales to predict the price properties would have sold for on the Appraisal date
  • For tax years 2019 and 2020, the assessor must use a minimum of the comparable sales between January 1st, 2017 and June 30th, 2018. However, the assessor may include and analyze additional sales that occurred up to five years preceding June 30th, 2018, adding sales in six month increments. Gunnison County typically uses a minimum of 24 months which includes all sales consummated after the previous reappraisal, and accounts for seasonal differences in the market. For the 2019 reappraisal, it was necessary to extend the time period to 5 years for commercial property, between 2 to 5 years for vacant land, and 2 to 3 years for residential improved, depending on the economic area and neighborhood

Information Collection

The first step in the assessment process is to gather information on ownership, location, use, sales, building measurements, construction type, construction costs, and rental income.

Primary sources for this information are real property deeds and declarations, subdivision maps, building permits, and local building contractors. Other primary sources are declarations filed by owners of taxable personal property and appraisers who conduct on-site inspections to gather land and building characteristics. The assessor stores, updates, and maintains this information for current and future use in the assessment process. Other factors that influence value may be location, availability of services, and rental rates.

A property's value may alter over time due to physical changes, such as new rooms finished in the basement or extensive remodeling and modernization. Changes made to maintain your property's current value, such as painting your home, replacing your roof or making repairs would not necessarily increase the value of the property. But, if these tasks were not performed, the condition of the home would deteriorate which could adversely affect the value.

Most of the information gathered by the Assessor is public record and all of the public information available on individual properties is provided on our website through the property record search.
