Tiny home rules in Waipahu, HI — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Waipahu has no separate tiny-home category. Permanent tiny homes on foundations are regulated as ADUs, and movable tiny homes on wheels are not allowed as permanent dwellings.
Honolulu has no dedicated tiny-home ordinance. Under ROH Sec. 21-5.720, permanent tiny homes on foundations in Waipahu are regulated as accessory dwelling units, subject to size, parking, occupancy, and setback rules. Movable tiny homes on wheels fall under state and county rules for recreational vehicles and are generally prohibited as permanent dwellings in residential zoning districts. Building code adoption is at ROH Sec. 16-1.1. Waipahu's dense lots and multi-generational households make compact ADU-style tiny homes appealing, but lot-size and parking rules still apply.
Living in a tiny home on wheels in a residential district or placing a permanent tiny home without an ADU permit can result in zoning enforcement action.
