Metro Denver Assessors Announce Real Property Valuations

Published on April 30, 2025

Denver, CO— Eight metro-Denver area Assessors today announced the results of the biennial revaluation of real property for their respective counties. Residential property in the Denver metropolitan area experienced relatively flat value changes, unlike the previous reassessment announced in 2023. The valuations announced today reflect values as of June 30, 2024, using data from the preceding two-year timeframe. It is important to recognize that each county has unique real estate trends, and research of local sales is critical to fully understand those sub-markets.

According to Colorado statutes, real property is revalued every two years in odd-numbered years observing transactions and market conditions from the timeframe of July 1, 2022, through June 30, 2024. Notices of valuation will be mailed to property owners by May 1, 2025. Property owners are encouraged to visit their Assessor’s website to review property characteristics and research sales that occurred in their area during the statutory timeframe, and if they feel the value is in error, an appeal can be filed between May 1 and June 9, 2025. In the Denver metropolitan area, most Assessors offer online appeal applications, and all accept written filings either via mail or drop off.

Certified property values are one part of a three-part equation to determine property taxes. The assessment rate, determined by the state legislature, and the tax rate (or mill levy), set by the various taxing authorities, are the other core components of determining property taxes. Property owners will not know the amount of their property taxes due in 2026 until the end of the year when both the tax rate and the assessment rate are set for each county.

Quotes from County Assessors:

Adams County Assessor Ken Musso said “Adams County experienced market conditions similar to Denver and the other metro counties in this valuation cycle. Sales were limited, compared to the last cycle, due to higher interest rates and market uncertainty. Most of the residential market areas in Adams County showed a decrease in value from -2% to -6%. We encourage property owners to review their account values and characteristics. Account, market and appeal information can be found on our website adcogov.org/assessor.”

Arapahoe County Assessor PK Kaiser said “The big news this year is that residential property values have remained relatively flat, and in some cases, even decreased slightly over the 2023 assessment period. For many of us who have experienced double-digit increases in property values the last few years that greatly affected our property taxes, this will come as a welcomed change. That said, those who want to appeal their property valuation are encouraged to do so before the June 9 deadline.”

Boulder County Assessor Cynthia Braddock said “Boulder County has seen a slowing in the real estate market similar to the Metro Denver Counties. Boulder County continues to be a desirable place to live and work; with most property values remaining stable. We encourage property owners to double-check their property information and review comparable property sales via our website. If they find any errors or disagree with the values, they are encouraged to file an appeal by the June 9 deadline."

City and County of Broomfield Assessor Jay Yamashita said “The City and County of Broomfield experienced a flat residential valuation market due to a weaker real estate market. Property owners should review their Notice of Valuations as soon as they are received and contact the Assessor’s Office with any questions. New for 2025 is an online appeal portal available on May 1, 2025, at Broomfield.org/AppealInformation.”

City and County of Denver Assessor Keith Erffmeyer said “We strive to value Denver’s properties as accurately as possible. We encourage Denver property owners to visit new denvergov.org/property website to verify details of their property and to use our efficient and effective appeals process if they have questions or documents to support a different valuation or classification of their property.

Douglas County Assessor Toby Damisch said “Since the last reappraisal, sales volume has decreased significantly in Douglas County across most property classes, with residential property affected the most. Home price levels have also dropped since the peak of the market in the spring of 2022, with nearly two-thirds of residences decreasing in value, most by single digits. Cost of homeownership remains very high, including elevated property taxes remaining from the last reappraisal, and is having a significant negative effect on the housing market. Aside from home prices, apartment building values and most commercial valuations have been stable with relatively flat value changes, as has vacant land. Large office buildings are an outlier this year, as there have been some indications of market stress that are reducing these assessments.”

Jefferson County Assessor Scot Kersgaard said “Few people will see the value of their property rise exactly 2%. Every area and every type of property has its own sales trends. Some will see their value up 10-15%, while many others will see no increase or even a small decrease. In fact, 64% of residential properties had declines or gains of less than 5%.”

Larimer County Assessor Bob Overbeck said “Even with a slowdown in real estate sales and relatively stable housing prices, demand remains strong for homes near Larimer County’s scenic parks, quality schools, trails, open spaces, and Rocky Mountain National Park. As of 2025, the median home price in the county is $550,600."
