Tiny home rules in Urban Honolulu, 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.
Urban Honolulu has no dedicated tiny-home ordinance; permanent tiny homes are regulated as ADUs under ROH Sec. 21-5.720, which effectively limits them to R-5 through R-20 neighborhoods outside the dense apartment core.
The Revised Ordinances of Honolulu treat permanent tiny homes as ADUs under Sec. 21-5.720, meaning they are generally restricted to Country and R-3.5 through R-20 residential zones. In Urban Honolulu, this excludes most of Waikiki, Ala Moana, Kakaako, and downtown where apartment and mixed-use zoning dominates. Eligible tiny-home sites exist in Manoa, Kaimuki, Nuuanu, Palolo, and similar single-family areas. Building code adoption at ROH Sec. 16-1.1 requires tiny homes on foundations to comply with the adopted residential code. Tiny homes on wheels are classified as recreational vehicles and cannot serve as permanent residences in residential districts.
Living in an unpermitted tiny home, placing an RV-style tiny home as a residence, or siting one in an apartment or commercial district can result in civil fines and removal orders.
