 Honolulu, Hawaii, has "Ohana Dwelling Units," which although similar to ADUs, limit occupancy to "family" and have other regulatory requirements.Ohana Dwellings in Hawaii were created as an allowed use in the zoning code in 1981 as a way to encourage the private sector to create more housing units (without government subsidy), preserve green fields (open space) and ease housing affordability.In 2015, Honolulu amended its zoning code to add a new use—ADUs—as a sort of Ohana Dwelling, but with fewer restrictions.
