Marshall Fire

Assessor Information for those impacted by the Marshall Fire

The Boulder County Assessor’s Office will work to assist county residents to reach a fair market value for any property that was destroyed or damaged by the Marshall Fire.

Property values, which are used to determine annual property tax payments, will be adjusted downward to reflect the destruction to a physical residence or structure. In all cases your land values will hold its value, but the physical residence or structure will be prorated to reflect the reduction in value caused by the fire in the year of the destruction or damage.

  • For Destroyed properties (in 2021) the State of Colorado will reimburse Boulder County taxes for the destroyed physical residence or structure. Property owners will receive a tax bill for the land only assessed at the residential rate of 7.15%
  • Damaged properties will receive a 2021 tax bill for the entire property (land and structure) at the assessment rate of 7.15%.

Additionally, upon request, and free of charge, we can provide copies all official valuation documents, property descriptions, photographs, and more.

The documents below contain further explanation of the Assessor’s process in valuing properties destroyed and damage by natural causes:
