B-2 Community Business
The mid-tier business district for Honolulu's commercial corridors. B-2 doubles the height allowance over B-1 (45 ft vs. 25 ft) while maintaining the same 80% lot coverage, enabling four-story mixed-use buildings and larger commercial developments on standard lots.
Common locations: Kapiolani Boulevard commercial sections, Ala Moana Blvd, portions of King Street and Beretania Street, and major commercial nodes outside Kakaako.
