We’ve Changed How We Process Address Changes

We’ve worked with the Assessor and their partner, Just Appraised, to improve the way we process address changes. To enter an address change, you’ll need to register for an account, if you don’t already have one, and then log in, after confirming the e-mail address you entered during registration. Once you’ve logged in, look for the form called “Change of Address” and follow the instructions for completing it. Your change of address will be sent to both the Assessor and Treasurer.

Access the change of address form on Boulder County’s Just Appraised page.
