Honolulu FAQ
Do I need a permit to install an above-ground pool in Honolulu?

What fence is required around a residential pool?
ROH § 16-6.2 requires a barrier at least 48 inches high with self-closing, self-latching gates; gaps may not allow passage of a 4-inch diameter sphere.

Generally no. Pools must clear utility and drainage easements. DPP review during Chapter 18 permit issuance flags conflicts before construction starts.
What if my Waipahu lot is too small for a code-compliant pool?
You may need a variance from the Land Use Ordinance in addition to the Chapter 18 permit, or consider a smaller spa that still meets Article 6 barrier rules.
