About Historic Hawai‘i Foundation

Historic Hawai‘i Foundation is a statewide, membership-based 501(c)(3) nonprofit founded in 1974 that advocates for the preservation of Hawai‘i’s historic buildings, sites, cultural landscapes and communities. The organization provides grants, technical assistance, education, advocacy, and hands-on stewardship programs to support preservation work across the islands. In recent years Historic Hawai‘i Foundation has been active in recovery and planning after the August 2023 Lahaina wildfires, launched and advanced a Native Hawaiian Organization Stewardship Program to support culturally grounded site stewardship, produced digital story maps (for example the Kōloa Story Map) and continued its long-standing Preservation Honor Awards program. The organization’s EIN (23-7441972) and Form 990 filings are publicly available and match the charity’s official identity and web presence.
