Tiny home rules in Lake Havasu City, 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.
In Mohave County, a tiny home on a permanent foundation is a dwelling built to the 2018 IRC and may qualify as an accessory residence, while a tiny home on wheels is an RV that cannot be a permanent residence on a standard residential lot.
Classification decides how Mohave County treats a tiny home. A tiny house on a permanent foundation is a dwelling under the 2018 IRC and may serve as the primary home if the lot meets its zone, or as an accessory residence under Ordinance 2025-06, which allows one attached and one detached unit per single-family property. The IRC's tiny-house provisions cover homes 400 square feet or less, allowing reduced ceiling heights and loft access. A tiny home on wheels registered as a travel trailer or park-model RV does not meet the building code as a permanent home and cannot be lived in full-time on a standard residential lot outside a licensed RV park.
Living full-time in a tiny home on wheels on a standard residential lot is a zoning violation subject to daily penalties. A foundation tiny home built without a permit draws a stop-work order.
