Tiny home rules in Kent, 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.
Kent allows foundation tiny homes as permanent dwellings under the WA Building Code and as ADUs under HB 1337. Tiny homes on wheels are RVs and cannot be permanent residences outside licensed parks.
Kent distinguishes between tiny homes on foundations (built to the Washington State Building Code and Appendix Q of the IRC for homes under 400 square feet) and tiny houses on wheels (THOWs). A foundation-built tiny home may serve as a primary residence or an ADU on any lot where residential dwellings are allowed, subject to ADU size caps under Title 15 and HB 1337 compliance. A THOW is legally an RV and cannot be used as a permanent dwelling on a residential lot. THOWs may be parked temporarily under Kent RV parking rules or in licensed RV parks and mobile-home parks. Tiny-home permits follow the same process as full-size single-family permits: land use review, building, plumbing, mechanical, and electrical. Critical Areas and floodplain standards apply. Homeless-response tiny shelters in licensed encampments are separate use.
