Tiny home rules in Mililani Mauka, 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.
Tiny homes in Mililani Mauka are regulated as ADUs under ROH Sec. 21-5.720 when on a foundation, but the Mililani Mauka Community Association often prohibits them outright; tiny homes on wheels are not permitted as dwellings.
Honolulu has no separate tiny-home ordinance. A permanent tiny home on a foundation is regulated as an accessory dwelling unit under ROH Sec. 21-5.720, meaning size, parking, setback, owner-occupancy, and 30-day minimum rental rules apply. Tiny homes on wheels are RVs under state and county rules and cannot be used as permanent dwellings in residential districts. In Mililani Mauka, the Community Association's covenants and design guidelines often prohibit detached secondary dwellings and any non-conforming architecture, making tiny homes difficult to approve even when the city would allow them. Building standards follow ROH Sec. 16-1.1.
RV dwellings on residential lots can trigger zoning citations; HOA enforcement may require removal or re-use.
