Spatial Distribution of ADUs in 2016

According to City data, there were 100 new ADUs (accessory dwelling units) created in Honolulu in 2016. All of them were mapped to identify which City Council District had the most and least new ADUs.

Ikaika Anderson's district tops the list with 36% or one out of every 3 ADUs. A closer look at the building permit data shows that 29 were in Kailua, 2 in Waimanalo, and 5 in Kaneohe. Trevor Ozawa's district of Hawaii Kai ranked second with 20% of all ADUs. Perhaps a surprise, Brandon Elefante's district that includes Pearl City and Waipahu, had the 3rd lowest rate, adding just 4 new ADUs. At the bottom of the list: Ron Menor's district that includes Kapolei and Mililani, did not have any ADUs.
