Assessor Level Appeals


If you disagree with the Assessor’s estimate of value, all property owners have the opportunity to appeal and provide evidence that it is inaccurate. The Douglas County Assessor provides several options to appeal property value from May 1 to June 8 each year (see Protest/Appeals Calendar). Reasons for an appeal might include:

  • Items that affect value are incorrect on your property record. You have an unfinished basement, not finished. You have a carport, not a garage. Your home has 1,600, not 2,000 square feet.
  • The estimated market value is too high. You have evidence that similar properties have sold for less than the estimated market value of your property.
  • The assessor’s record of acreage or square footage of land is incorrect.

Employees of the Assessor’s office have been trained to be polite and helpful. They will do anything within their means to help you get the information you need for an appeal. Please view them as an ally, not an adversary.

If you think your value is correct, but your taxes are too high, this is an issue you must take up with the officials who determine budgets for each taxing authority. Taxes can not be appealed through the Assessor’s office.

Appealing Your Property Value


Look up your property on the Assessor’s website.  This is easy to do from the Assessor home page.

Review the facts on the property record

Check the living area of your home, the size of your lot, the presence or absence of a garage or finished basement, the construction materials, the quality of construction and so on.

Review sales information for your specific neighborhood

Access “View Neighborhood Sales” from your Property Details page, or by clicking here. The results of this search will provide verified local sales that have been filtered to fall within the study period. You may also review the entire sales database with the Advanced Search reporting tool.

This application helps you review sales and their property characteristics. It is important to compare the features of these properties to yours. If there are differences, the values of the properties may be different.


The Assessor must make a decision and mail a Notice of Determination (NOD) to you before August 15th (the last working day in June during non-reappraisal years).


If you disagree with the Assessor’s determination, you can file a written appeal with the County Board of Equalization (CBOE) on or before September 15 (during non-reappraisal years the deadline is July 15) for real or personal property. The CBOE schedules and completes their hearings before November 1 (August 5 in non-reappraisal years). The board must notify you in writing within five business days after their decision is made.

If you are satisfied with the CBOE decision, the process ends there.

If not there are three options:

  1. Go to binding Arbitration,
  2. Appeal to the Board of Assessment Appeals (BAA), or
  3. Go to District Court

You must appeal within 30 days of the CBOE decision.

If you choose Arbitration after the CBOE decision, the decision reached at Arbitration is final and not subject to review.

If you are satisfied with the decision rendered by either the BAA or District Court, the process ends there. If, however, the decision rendered by either the BAA or District Court is unsatisfactory, you may then appeal to the Court of Appeals within 30 days of the BAA decision or 45 days of a District Court decision. The only appeal beyond that is to the Colorado Supreme Court.
