Pearl City structure heights follow ROH 21-4.60 with residential envelope planes in 21-3.70-1, typically 25 feet in R-5 districts covering Waiau, Manana, and the core Pearl City CDP.
ROH/LUO Sec. 21-4.60 sets maximum structure heights and introduces the building envelope plane concept. District-specific residential limits in ROH 21-3.70-1 generally apply a 25-foot cap in R-5 districts covering most of Pearl City and 30-foot limits in R-7.5 and R-10 districts in Pearl City Highlands. Pearl City lies near Joint Base Pearl Harbor-Hickam and FAA Part 77 imaginary surfaces further cap absolute heights near flight paths. Rooftop equipment, chimneys, and solar structures receive limited exceptions in 21-4.60 but must still respect envelope planes. Two-story plantation-era homes in Waimalu typically comply without issue, but remodels adding a full third story usually require variances.
Exceeding district height prompts notices of violation, can force structural alteration or partial demolition, and accrues daily civil fines under LUO enforcement.
