What Counts as a Successful Appeal?

An appeal is considered successful when the result shows a Change.

If the result shows No Change, the assessed value stays the same.

This distinction is important because your assessed value helps determine your property tax bill. If the value goes down, your share of taxes may also go down.

Appeal Success Rate by Property Class

• 2-05: Two-or-more story residence, over 62 years old, up to 2,200 sq ft

• 2-06: Two-or-more story residence, over 62 years old, larger size range

• 2-11: Apartment building with 2 to 6 units

• 2-99: Residential condominium

• 3-15: Two-or three-story apartment building (multi-family)

• 5-17: One-story commercial building

What the Data Shows
