March 26, 2026

Recently, a notice was mailed to Olmsted County property owners regarding the 2026 assessed value and/or classification of their property. 

If property owners do not agree with their estimated market value, they are encouraged to follow these steps to begin the appeal process:

• Contact the Olmsted County Assessor’s Office. 
  • Collect documentation to support your opinion (e.g., a recent appraisal, recent sale of like property, recent change in revenue, etc.). 
  • Call 507-328-7670. 
  • Visit the Assessor’s Office located at 151 4th Street SE in Rochester, 8 a.m. – 4 p.m., Monday through Friday. 

• If property owners are not satisfied after their discussion with the Olmsted County Assessor’s Office, they are welcome to attend the appropriate meeting of their Local Board of Appeal and Equalization (LBAE) or the Open Book meeting listed on their Valuation Notice. Go to the Olmsted County website and select “If the issue is not resolved” for more information on meeting dates and times. If a meeting is not offered in your jurisdiction, please call 507-328-7670.

Property owners must have attended a local board of appeals meeting or called 507-328-7670 if a meeting is not offered in their jurisdiction, prior to attending the county board of appeals. If your jurisdiction has an open book meeting, you may appeal directly to the county board of appeals.
