Property Ownership

What is 'accessory dwelling unit' (ADU) and how has Hawaii addressed its housing shortage through ADUs?

AA. ADUs are prohibited in all Hawaii residential zones to maintain neighborhood character
BB. ADUs (ohana units, carriage houses, basement apartments) are secondary dwelling units; Hawaii has enacted legislation encouraging ADU construction to increase housing supply on existing residential lots✓ Correct
CC. ADUs are only permitted in resort zones in Hawaii
DD. Hawaii requires government approval at the state level for all ADU construction

Explanation

ADUs (accessory dwelling units) are smaller, secondary housing units on the same lot as a primary residence. Hawaii has streamlined ADU permitting and updated zoning to encourage construction as a solution to the housing crisis. State law (Act 39, 2019) prohibits counties from imposing some restrictions that had limited ADU construction. ADUs provide multigenerational housing and additional rental income for homeowners.
