Kapolei FAQ
Is Kapolei itself within the SMA?
Most of the Kapolei urban core is inland of the SMA, but coastal-adjacent parcels and certain corridors may fall within the SMA boundary.
Do I need an SMA permit to rebuild a coastal-area wall?
Possibly. Any development within the SMA meeting Chapter 25's thresholds requires an SMA minor or major permit before work begins.
Mililani Mauka FAQ
Does my Mililani Mauka home need an SMA permit?
Almost certainly not, since the community sits inland well outside SMA boundaries, but always confirm with the Department of Planning and Permitting.
I own a beach lot elsewhere. Does Chapter 25 apply?
Yes. SMA rules apply based on the location of the project, so any coastal-area development on Oahu is governed by ROH Chapter 25.
