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.

Most Pearl City residential districts cap structure height at 25 feet in R-5 and 30 feet in R-7.5 and R-10 under ROH 21-4.60 and 21-3.70-1 envelope planes. FAA limits may apply near flight paths.
Does proximity to Pearl Harbor affect height?
Yes. FAA Part 77 imaginary surfaces may restrict absolute building height near the Joint Base approach corridors. Homes in some Pearl City areas must review both ROH and FAA limits before adding stories.
