Assessor Department


Routine Property Review

The Assessor’s Office is required by State law to physically review your property at least once every five years and record any changes in property characteristics since their last visit. This review is part of an ongoing revaluation program to ensure the accuracy of our data and to assist us in estimating a fair and equitable value of your property for property tax purposes. This process is known as the quintile review. Reference (Minnesota Statutes, section 273.01)

In light of COVID-19 and for the protection of our property owners and staff we will be completing exterior property reviews only. No tag will be left on your door. Property owners will receive a letter asking them to call our office to verify their property information.

Please call 507-233-6606 if you have additional questions or concerns.

Homestead Applications:

There is a drop box located in the Law Enforcement Center parking lot off of Washington Street. If you have a homestead application to drop off, we encourage you to utilize the drop box. Again, if you have any questions we will be able to assist you over the phone @ 507-233-6606.
