Certification is now available at the Tiny House Registry, for tiny houses on wheels. Certification provides a path for documenting the construction of a tiny house on wheels, demonstrating that it meets specific guidelines and is intended for use as a permanent residence.
Guidelines are provided only for tiny houses on wheels (THOWs) for a couple of reasons:
- Houses on foundations are already considered permanent residences, whereas THOWs are considered RVs and therefore not to be lived in permanently. By providing a new definition and another set of guidelines, we hope THOWs will eventually be accepted as homes rather than recreational vehicles.
- Houses on foundations already have an extensive set of guidelines, the International Residential Code for One- and Two-Family Dwellings. THOWs don’t have any standards, so some folks are making dangerous mistakes in construction. RVIA standards address electrical and plumbing systems but don’t cover the structural elements and aren’t intended to provide a durable, all-season home.
