Rio Grande County address changes for tax records need a signed request

Moved, or changed your mailing address while owning property in Rio Grande County? This is one update you cannot phone in. The Assessor accepts an address change only in written form, signed by at least one current owner. A call or a casual mention does not count.

The reason is worth understanding, because it explains why the rule feels stricter than it needs to be. Your tax notices and your assessment notices both follow whatever mailing address sits in the county record, here in Del Norte, the Rio Grande County seat. Get that address wrong and the mail keeps flowing — just to the wrong door. You end up missing paperwork you would much rather have seen early, while deadlines tick by without you.

The signature does double duty. Beyond pointing the mail correctly, requiring a current owner’s written, signed request makes it far harder for someone else to quietly reroute your property notices and slip a fraudulent change past the office. That small friction is protecting you.

So fold it into the moments when addresses tend to drift. Just closed on a place? Pull up the Assessor’s record and file the address-change form if anything is off. Already own and about to move? Send the signed change in before the next tax season finds you at an address you left behind.
