  • Distribution Partner: Inter-Island Solar Supply
  • Installer: HI Tech Plumbing
  • Completed: 2022

Project Overview

Nanakuli Homestead, located in Waiʻanae, Oʻahu, represents a transformative project aimed at addressing overcrowded living conditions, beach evictions, and neglected homes in the Nanakuli Homestead community. In response to these challenges, a cooperative effort was initiated involving various organizations, including the Nanakuli Hawaiian Homestead Community Association (the neighborhood association), Urban Housing Communities (UHC), USDA Rural Development, Department of Hawaiian Homelands, Hawaiian Housing Finance and Development Corporation, and Hawaiian Community Development.

UHC introduced an innovative financing structure, never before used in Hawaii, to fund the construction of 48 affordable apartments at substantially below-market rents. This initiative serves as a lifeline for Oahu's most vulnerable families, providing them with homes in a community that beautifully reflects Hawaii's cultural heritage.

The project, part of the larger Nanakuli "village center," offers a range of on-site amenities, including a resource center, BBQ/picnic area, tot lot, laundry facilities, secure gated access, onsite security, and a dedicated manager. These features create a welcoming and safe environment for residents.
