Waipahu structure heights follow ROH 21-4.60 with envelope planes in 21-3.70-1, typically 25 feet in R-5 districts and higher caps in A-1 and A-2 districts near Waipahu Town Center.
ROH/LUO Sec. 21-4.60 sets maximum structure heights with building envelope plane controls. District-specific residential limits in ROH 21-3.70-1 typically apply a 25-foot cap in R-5 districts covering the core Waipahu plantation blocks. Apartment districts A-1 and A-2 near Waipahu Town and Waipahu Street allow substantially taller structures, reflecting the CDP's dense working-class multi-family character. Rooftop equipment, chimneys, and solar structures receive limited exceptions in 21-4.60 but must respect envelope planes. Two-story plantation homes typically comply, but adding full third stories often requires variances. Waipahu Cultural Garden Park adjacency can add design review for taller projects.
Exceeding district height prompts notices of violation, can force structural alteration or partial demolition, and accrues daily civil fines under LUO enforcement.
