Special Assessments
Aug. 12, 2025 —City of Mandan staff recently launched a new dashboard that will allow users to search a parcel or address for the property’s current special assessment balance. This joint effort across several departments is intended to make it easier for individuals to view current special assessments on a property and make online payments.
The Special Assessment Inquiry dashboard is available here or at cityofmandan.com/specials.
