Urban Honolulu FAQ
Does a Waikiki hotel renovation need an SMA permit?
Usually yes. Waikiki is entirely within the SMA, so most exterior and valuation-triggered work needs at least an SMA minor permit under Sec. 25-5.2 and often a major permit.
How does HCDA review interact with SMA permits in Kakaako makai?
HCDA handles Kakaako development plan approvals, while SMA permits under Chapter 25 apply separately for projects within the SMA boundary, requiring both approvals in many cases.
Waipahu FAQ
Does SMA apply to Waipahu properties near West Loch?
Properties inside the Special Management Area boundary inland of the West Loch shoreline require SMA permit review under Chapter 25 for qualifying development activities.
How do I find the SMA boundary for my parcel?
The Department of Planning and Permitting and city GIS maps show the Special Management Area boundary. You can also request a determination from planning staff.
