The island of Oahu (Honolulu County, Hawai’i) is facing a shortage of housing for its growing senior population. The construction of accessory dwelling units (ADUs), or small, second homes built on the same lot. for senior housing may be a possible solution. A qualitative document review was utilized to examine the existing Honolulu ADU cost reduction for those wishing to build an ADU on their properties for the purposes of senior housing. There were several publications and articles found through the search. From these articles, four major themes emerged: tax breaks, financing options, green building, and sharing of utilities. These themes led to a secondary level document review and analysis of each of these themes.
