No. LUO Sec. 21-4.70 permits native Hawaiian species as landscape substitutions but does not require them citywide. Kakaako master plans encourage native use voluntarily.

Yes, HOAs and condo boards may set stricter plant lists for common areas; the city does not preempt those internal rules so long as LUO landscape minimums are met.
