Mililani Mauka FAQ

My Mililani Mauka lot slopes downhill. Does that change the permit?

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.

Pearl City FAQ

Can I pull a homeowner permit instead of hiring a licensed contractor?

Hawaii limits owner-builder permits and pool work typically requires licensed trade contractors for plumbing and electrical; check DPP homeowner rules before applying.

Do I need a new permit to replace my pool heater?

Yes when wiring, gas lines, or plumbing change. A straight like-for-like swap without altered utilities may qualify for a simplified trade permit only.
