East Honolulu residential lot coverage follows ROH 21-3.70-1, which caps impervious surface at 75 percent for dwellings permitted after May 1, 2019, impacting Hawaii Kai marina and ridge parcels.
ROH/LUO Sec. 21-3.70-1 sets residential district standards including the 75 percent impervious-surface cap for dwellings permitted after May 1, 2019. In Hawaii Kai Marina parcels, Portlock oceanfront lots, Hawaii Loa Ridge, and Kuliouou hillside lots, the cap limits driveway, pool, and hardscape expansion that would otherwise stress drainage infrastructure. Pre-2019 homes may exceed the cap as legally nonconforming but lose that status when substantially redeveloped. The impervious cap interacts with Chapter 14 drainage rules, and DPP often requires stormwater BMPs for projects close to the threshold. Tree canopy and permeable pavers can count toward compliance in limited circumstances.
Exceeding the impervious cap can block building permit issuance, require redesign before continuation, and force removal of excess hardscape with after-the-fact fees.
