Kaneohe FAQ
Can I add a third story to my Kaneohe home?
Usually not in R-5 zoning, as the 25 to 30 foot cap generally restricts residential structures to two stories plus roof.
Do rooftop decks count toward height?
Usable rooftop decks with railings often count as an additional story and may exceed envelope-plane limits; check with DPP.
Urban Honolulu FAQ
How tall can I build a house in Urban Honolulu?
Most residential districts cap structures at 25 feet under ROH 21-4.60 with a 30-foot envelope plane rising from side yards. Apartment and mixed-use districts in Waikiki and Kakaako allow much taller buildings.
Why are Waikiki and Kakaako buildings so much taller?
Those districts carry separate height maximums under special district rules and, in Kakaako, Hawaii Community Development Authority oversight. View-corridor protections still limit where high-rises may rise.
