Tiny home rules in Hamilton County, OH — 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.
Hamilton County has no countywide tiny-home ordinance. Whether a tiny house on a foundation or on wheels is allowed depends on your municipality's or township's zoning resolution under ORC Chapter 519 and the Ohio Residential Code.
Ohio townships regulate the size, use, and location of dwellings under ORC 519.02, and municipalities do so through their own zoning codes. Site-built tiny homes on foundations are treated as dwellings and must meet minimum-size, setback, and Ohio Residential Code standards where they apply. Tiny houses on wheels are often classified as recreational vehicles or trailer coaches (which ORC 519.02 expressly lets townships regulate) and may be barred as permanent residences outside licensed parks. There is no single Hamilton County answer; check your local zoning office for minimum dwelling size and whether RV-style tiny homes are permitted.
Local zoning enforces via citations and fines; unpermitted tiny homes may be declared illegal dwellings and ordered removed.
