Tiny home rules in Spokane County, WA — 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.
Spokane County has no separate tiny-home ordinance. A permanent tiny house on a foundation is regulated as a single-family dwelling or accessory dwelling unit under Zoning Code Chapter 14.606; a tiny house on wheels is treated as a recreational vehicle and can't be used as a permanent residence in most
There is no standalone tiny-home category in the Spokane County Zoning Code. A tiny house built to residential building code on a permanent foundation is a single-family dwelling; if it is a second unit it must meet the ADU standards of SCC 14.606, including the detached-ADU 800 sq ft ground-floor cap, 2-bedroom limit, and 10,000 sq ft minimum lot. Manufactured homes built to HUD standards are also treated as single-family dwellings. A tiny house on wheels is generally a recreational vehicle under state law and cannot serve as a permanent dwelling in residential zones. The county sets no minimum dwelling-size floor beyond building-code habitability requirements, so most 'tiny homes' fit within existing dwelling and ADU rules.
Occupying a tiny house on wheels or an RV as a permanent residence in a residential zone, or building without permits, is a code violation enforced by Spokane County Building and Planning.
