ROH Sec. 21-4.60 sets maximum structure heights for Mililani Mauka, with residential districts typically capping homes at 25 to 30 feet and applying sloped envelope planes.
Height limits in Mililani Mauka are defined by a combination of absolute caps and building envelope planes that slope inward from each side yard. ROH 21-4.60 establishes the measurement approach, while 21-3.70-1 provides the residential numbers. Most Mauka homes are capped around 25 to 30 feet with envelope planes that prevent tall second-story massing near neighbors. Rooftop chimneys, solar equipment, and minor architectural features may qualify for limited exceptions. MTA design review also evaluates scale and massing, sometimes requiring step-backs beyond the city's envelope requirements.
Plan check rejection, redesign expense, and fines where built work exceeds the allowed height or envelope.
