Kailua and Honolulu County
Kailua is associated with Honolulu 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.
Kailua by land and water
The Census records 2.82 square miles of water within Kailua, or 26.6% of its total area. It is 45.6 percentage points lower than the 72.3% recorded for Honolulu County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Kailua CDP has 4.3 times the land area of nearby Maunawili CDP (1.83 square miles). These areas describe boundaries, not comparable property prices.
