Addison and DuPage County
Addison is associated with DuPage County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Addison by land and water
The Census records 0.63 square miles of water within Addison, or 2% of its total area. It is 0.6 percentage points lower than the 2.5% recorded for DuPage County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Addison township has 6.5 times the land area of nearby Wood Dale city (4.87 square miles). These areas describe boundaries, not comparable property prices.
