Hawaii has a high elderly population compared to the mainland United States. There are a number of factors that contribute to the high percentage of elderly in Hawaii, which includes lifestyle, weather, genetics, and diet, to name but a few. Currently, there are a limited number of housing options available for the elderly in Hawaii. Current forecasts indicate an increase in the retirement population, which will further stress the elderly housing situation of the State. The theory of senior cohousing communities, as an alternative form of elderly housing in Hawaii, is based on a literature review of the historical successes already in practice in other locations outside of Hawaii. Case studies of faith-based organizations in Hawaii that exemplify designing, building, and living in community were chosen, analyzed, and incorporated into a prototype design that is reflective of Hawaii. Surveys of senior residents, currently living in a community setting in Hawaii, were conducted. GIS mapping was utilized to determine the optimal site selection for locating community resources that are vital to the elderly population. Senior cohousing communities can offer seniors the security of living amongst other seniors who will be integral members in their daily lives. Faith-based organizations can be the foundation upon which these communities are built. Inherent components of these organizations could include land holdings, outreach social services, parish ministries, and community-service programs. All of these can play a vital role in the success of these communities. Senior cohousing communities can be another alternative to the current senior housing options available in Hawaii. The compilation of this project’s research and findings has resulted in a guideline that can aid the public in the process, site selection and design to further the development of such communities
