Tiny home rules in Pinal County, AZ — 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.
A permanent tiny home on a foundation is regulated as a single-family dwelling or an accessory dwelling unit and must meet the building code and ADU rules. Pinal County's zoning code bars mobile or manufactured homes as a guest house/casita except where such homes are permitted in the zone.
Pinal County has no separate 'tiny home' ordinance. A tiny house built on a permanent foundation is reviewed as a site-built single-family dwelling or, if it is a second unit on the lot, as an accessory dwelling unit subject to the county's ADU size, number, and five-foot setback rules. A tiny house on wheels is treated as a recreational vehicle or manufactured/mobile home and cannot be used as permanent housing unless the zone allows it. The zoning code specifically provides that mobile homes and manufactured homes are prohibited as a guest house or casita, except where a mobile home or manufactured home is a permitted use in the zone. Cities apply their own tiny-home standards.
Placing or occupying a tiny home in violation of zoning or the building code is a violation subject to fines, stop-work orders, and removal by Pinal County.
