Waipahu FAQ
What setback applies to a Waipahu home?
Most Waipahu R-5 lots require a 10-foot front yard and 5-foot side and rear yards under ROH 21-4.30 and 21-3.70-1. Plantation-era homes on narrow lots may be grandfathered with smaller setbacks.
Can I add an ADU on a small plantation lot?
Possibly. ADUs must meet ROH 21-4.30 setbacks plus ADU-specific rules. Narrow plantation lots often lack the side yard required for an ADU, so DPP pre-review with a licensed design professional is recommended.
