Both the Grand County Assessor's Office and the Treasurer's Office participate in the eNotice online program. Simply go to to log into the eNotice website. This program allows a property owner to receive their tax and valuation notices via email instead of by regular mail. As an added benefit, the website will have a repository of all the notices sent this way for future access by the property owner. Each owner that signs up will have a separate and distinct account. This is a convenient way to receive notices and have easy access to those notices at any time, day or night.

Changing a Physical (situs) Address

The process to change a physical (situs) address for a property is to submit a written or email request to either the GIS or Assessor's Office, preferably from the owner of the property. Governmental or emergency service agencies may verbally request a change, in which case the property owner will be notified by mail at the mailing address we have on file.
