Equity is not an approach to value, yet for assessment purposes it can be as important as one. Equity is all about fairness. Specifically that your property tax burden is fair when compared to your neighbor, or your competition. Most states that I have worked in require that tax jurisdictions must assess based on equity, or “uniformity.” This is to ensure that the tax burden is distributed fairly. The exceptions that I am aware of are Florida and Ohio. (Full disclosure: I have worked property tax appeals in ME, VT, NH, MA, CT, RI, NY, PA, NJ, DE, MD, VA, WV, OH, NC, SC, GA, AL, FL)
