Kailua FAQ
Is my Kailua home in the SMA?
Properties within a set distance of the shoreline are likely inside the SMA; check the city's SMA map or contact DPP to confirm.
Do repairs need an SMA permit?
Ordinary maintenance is usually exempt, but structural additions or changes to footprint typically require at least a minor SMA permit.
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.
