Honolulu FAQ
Must I live on the lot to have a Honolulu ADU?
Not under city law. Honolulu's Bill 7 ADU program does not require owner occupancy. However, the ADU must be operated as a long-term rental (180+ day leases) under a recorded covenant on the property.
Can I sell my Honolulu ADU separately from the main house?
No. The ADU must remain part of the same legal lot as the principal dwelling. Hawaii's condominium property regime statute (HRS 514B) is the only path to separate ownership and is not used to subdivide ADU lots.
