ROH Sec. 21-4.60 limits Mililani Town residential building heights to roughly 25 feet flat or 30 feet pitched, with HOA guidelines often further restricting visible bulk in this master-planned community.
Under ROH 21-4.60 and 21-3.70-1, Mililani residential structures typically cannot exceed 25 feet for flat roofs or 30 feet under pitched-roof envelope planes. Height is measured from grade to the highest roof point, with limited allowances for chimneys and equipment. Mililani HOAs frequently restrict second-story additions, dormers, and rooftop structures through design review, even where ROH would permit them. The Ko'olau and Wai'anae mountain views are part of the community aesthetic, and HOA guidelines emphasize preserving those view corridors. Commercial zones near Mililani Town Center and Mauka have their own heights.
Height violations can force roof modifications or demolition, void occupancy certificates, and bring HOA enforcement including fines and liens.
