City of Aspen adopts a standard "Building Valuation Table" published by the International Conference of Building Officials in the Building Standards Magazine. The square footage is multiplied by the value provided to obtain an assigned value for the proposed structure which reflects the cost of construction for this region. The permit and plan check fees are based on average of that estimated cost. Please see City of Aspen Valuation Policies for Residential (PDF) and Commercial (PDF) projects. If your project's valuation does not match our policy, please see the Valuation Adjustment Policy (PDF).
