East Honolulu FAQ

Purely cosmetic replastering usually is exempt, but equipment replacement that alters plumbing or electrical circuits requires a trade permit under Chapter 18.

Yes. Sloped lots often require retaining-wall design, soils reports, and extra drainage details before DPP approves a pool permit.
Do I need a permit to replaster my existing pool?
Pure surface replastering typically does not require a permit, but any change to plumbing, structure, or barriers triggers permitting.
