Mililani Town landscaping may substitute native Hawaiian species under LUO Sec. 21-4.70; HOA guidelines may govern which are approved for front yards.
Mililani Town's suburban master plan originally emphasized uniform ornamental landscaping, but drought-tolerant natives like ilima, akia, and uki uki are increasingly used in Mililani Mauka. LUO Sec. 21-4.70 governs city landscape requirements and allows native Hawaiian species as substitutions for standard plantings. No ordinance requires native-only landscaping. The Board of Water Supply Xeriscape Program and the Oahu Planting Guide provide voluntary guidance. Mililani homeowners should also review MTA architectural guidelines, which may restrict certain messy or invasive species and occasionally require specific front-yard turf coverage to maintain neighborhood consistency expected in the master-planned community.
No city penalties for non-native choices. MTA architectural violations are handled by the association with fines per its declarations and bylaws.
