Tiny home rules in Davis County, UT — 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.
Davis County has no special tiny-home ordinance. A tiny house on a permanent foundation is treated as a single-family dwelling and must meet Utah's adopted building code and the zone's standards; a tiny home on wheels is an RV and cannot be a permanent residence in most residential zones.
Utah adopts the International Residential Code (including Appendix Q for dwellings under 400 square feet) statewide through the State Construction Code, and Davis County and its cities enforce it. A foundation-built tiny home must meet the IRC and the zone's lot-size, setback, and height rules, and it may also qualify as an internal or detached ADU under state and local law. Tiny homes on wheels are regulated as recreational vehicles and generally may not be occupied full-time on residential lots. There is no separate Davis County tiny-home ordinance; your city zoning governs.
Living full-time in an RV-style tiny home on a residential lot, or building without code compliance, can bring zoning enforcement and fines.
