Pearl City 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 in residential districts.
Honolulu has no dedicated tiny-home ordinance. Under ROH Sec. 21-5.720, permanent tiny homes on foundations in Pearl City 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. Military families exploring tiny-home options near Pearl Harbor should consult DPP early and also verify any base-specific housing rules that apply on federal land.
