Boulder County Assessor to mail property appraisal information for new construction – May 1

2020 property value notices will be mailed to owners of new construction and remodels; Annual appeals period runs from May 1 to June 1

Boulder County, Colo. - On May 1, the Boulder County Assessor’s Office will mail Notices of Value (NOVs) to owners whose properties have experienced a change in value over the past year due to the creation of a new lot or subdivision, new construction, an addition. remodel or other physical changes to an existing property, or to new owners who did not receive a tax bill in 2020.

The NOVs include customized property information such as the legal description, property description, and the value of the property (current and prior).

Real property value in Colorado is determined on a two-year cycle, with the main reappraisal period taking place in odd years. County assessors are responsible in even years for appraising the real property value of new construction and properties that undergo changes.

By Colorado law, the 2020 real property value is based on June 30, 2018 market data. (Real property values for the 2021 reappraisal will be based on market data as of June 30, 2020, absent of any legislative changes.)

Property Value Appeals

From May 1 through June 1, an owner may protest the real property value or the classification established by the Assessor. This is the taxpayer's opportunity to correct values based on misclassifications, errors in property descriptions, or other discrepancies that may exist in the property records. This period is open to all property owners in the county and is not limited to new construction and remodels only.

All appeals must be filed by June 1. The easiest way to file an appeal is through the online application at www.boco.org/AssessorAppeals.

Note about COVID-19 impacts

County Assessors in the State of Colorado recognize the impacts COVID 19 has had on Colorado’s economy this year; however, assessors do not have the authority to adjust the current (2020) market value. The Colorado Assessor’s Association is currently working with Colorado public officials to help find a way to address these issues The Assessor’s Office urges you to contact your local state representatives regarding the COVID-19 pandemic. Your local state legislators can be found on this website: https://leg.colorado.gov/find-my-legislator.

“We cannot accept appeals based on taxes or effects on property value due to the present pandemic crisis. As it stands now, the economic impacts of the current pandemic will be addressed in the 2021 revaluation of all real property,” said Cynthia Braddock, Boulder County Assessor.

“We are held to the valuation process established in the State Constitution and statutes that limit us from considering these impacts” Braddock added.
