The purpose of the NOV is to inform you of any increase or decrease in your property valuation and advise you of your right to appeal. The valuation is determined by the Assessor’s Office and is a factor used to calculate property taxes.

For residential properties, the valuation is the Assessor’s best evaluation of the market value of the home (what it would have sold for) as of June 30, 2022. The value is derived from market sales and applied to your property based on its characteristics as of January 1, 2023 (which considers renovations, construction, etc. that existed at the beginning of the year).

By state law, the Assessor’s Office, an independent elected office, reappraises all properties every other year. The BOCC does not set valuations or the assessment rate. For residential properties, Colorado law requires that the “market” approach to valuation is used. The market approach determines the value of a property by analyzing the selling price and characteristics of market sales of similar properties.

The deadline to submit an appeal for 2023 was June 8th. You can learn about your appeal and abatement options at summitcountyco.gov/appeals.

If there is incorrect information about bedrooms, square footage, land size, or other factors in your valuation, the Assessor’s Office would like to know so they can review your value accordingly.

While revenues would increase, the County’s obligations and expenses to serve the County have also increased due to inflation and labor pressure since the pandemic.
