Appeal Information

The Appeal Process

The month of May is set aside in the Assessor's Office for assisting property owners with questions and concerns. If you wish to appeal the valuation of your property, you may do so by emailing, by visiting the Citizens Assistance Center office at One Descombes Drive or mailing the appeal form that is included with the Notice of Valuation. The form must be signed by a property owner or their agent. Appeals cannot be accepted by phone.

The appeal period for real property is May 1 through June 8 of every year.

Appealing in a Reappraisal or Intervening Year

Colorado statute require all assessors to revalue all properties in a reappraisal (odd) year. In a reappraisal year, all property owners will receive a mailed Notice of Valuation. In an intervening (even) year, only properties with a change in value due to things like finished basements, additions, receive a mailed Notice of Valuation. Complete the Real Property Protest Form to appeal your value if you did not receive a Notice of Valuation.

By Colorado statute, only sales from July 1, 2020 through June 30, 2022 can be used to appeal the value. Qualified comparable sales can be accessed using the links below. Sales are listed by subdivision. Broomfield experienced significant increases in overall value for all residential property, reflecting the strong economic conditions across the city and county.

Sales that have occurred after June 30, 2022 cannot be used to appeal a value. Property listings cannot be used to appeal the value. Sales that have occurred after June 30, 2022 will be used in the 2025 reappraisal.

Reasons to Appeal

An appeal should concern one of two items:

  • The property characteristics. The number of baths, square footage of home or the basement being finished or unfinished are just a few things that can affect the property valuation.
  • The actual value is too high. By law the appraiser sets values on property using information from a 24 month sales data gathering period. Perhaps a property owner has proof that similar properties have sold for less during that time period.

Reasons Not to Appeal

You should not appeal if you feel your taxes due are too high. If you feel your value is fair but that your property taxes are too high, this is a matter to discuss with the taxing authorities.

The taxing authorities (school boards, special districts, etc.) hold annual public budget hearings to determine the funds needed for next year's operations, which will determine the mill levy. Most hearings are in the fall. Being present at the budget hearings makes you more involved and informed about the cost and quality of services provided. The assessor reports the total assessed value to the taxing authorities in December each year so an accurate mill levy can be set. View the FAQs for more information on mill levies and taxing authorities.

After Filing An Appeal

The BOE will conduct hearings through Aug. 5. BOE hearing results are then mailed as a Notice of Decision.

If you are unhappy with the BOE's decision, you can file an appeal with the Board of Assessment Appeals, District Court or enter into binding Arbitration, within 30 days of the decision. This information is provided in the decision mailed to you by the BOE.
