Our Purpose
Ripon Revaluation is an independent civic education and data platform built for property owners in the City of Ripon, Fond du Lac County, Wisconsin. When the 2026 assessment notices arrived with an aggregate 69% citywide revaluation increase, many homeowners had the same urgent questions: How much did my property change? What might that mean for my taxes? And how does my increase compare to my neighbors and ward?
This tool answers those questions with clear math, privacy-safe community comparisons, and practical resources for Open Book and Board of Review — without requiring you to navigate complex assessor documents alone.
Independent & Nonpartisan
This platform is not affiliated with or endorsed by the City of Ripon municipal government, Fond du Lac County, the State of Wisconsin, or Associated Appraisal Consultants, Inc. (the contracted assessor for the 2026 revaluation).
The 69% Revaluation & Community Data
The assessor reported an overall 69% aggregate increase in total assessed value across the City of Ripon — a market update revaluation required by Wisconsin law (Sec. 70.10, Wis. Stats.) to bring assessments to 100% of fair market value. That citywide figure does not mean every property increased exactly 69%, and a 69% valuation jump does not mean your property taxes will increase 69%.
By contributing assessment notice data through our unified submission form, Ripon residents help build an accurate, ward-level picture of how the revaluation actually landed across all 11 official election wards. This community-driven dataset supports informed conversations during Open Book and Board of Review.
