Frequently Asked Questions: Custom Tiny Houses on Wheels (THOWs) in Australia

1. What is a Tiny House on Wheels (THOW) in Australia? A THOW is a fully functional, permanent dwelling constructed on a heavy-duty trailer. Built to Australian road transport and residential standards, it offers a mobile, sustainable, and simplified living alternative.

2. How does a THOW differ from a caravan or camper trailer? THOWs are built to meet or exceed the National Construction Code (NCC) for habitable structures, using standard house materials (timber framing, insulation, plasterboard). Caravans are built to lighter, automotive-based standards (AS/NZS 3001) for recreational travel.

3. Is a THOW considered a caravan or a house for legal purposes? This is a grey area. Legally, it's classified as a caravan because it's on wheels and movable. However, for long-term placement, many councils assess it under their local planning schemes for "moveable dwellings" or as an ancillary structure.

4. Where can I legally park and live in my THOW in Australia? Permanent placement is subject to local council regulations. Common legal pathways include:

On private rural land (often easier with fewer restrictions).
As a secondary dwelling (granny flat) on an existing residential property, subject to council approval and specific rules.
In designated tiny house communities or some residential parks that allow them.
Short-term stays in caravan parks. You must always contact your local council first.
5. Do I need a special license to tow a THOW? If the combined Gross Vehicle Mass (GVM) of your tow vehicle and the THOW is under 4.5 tonnes, a standard car license (Class C) is sufficient. For heavier combinations, a Light Rigid (LR) license may be required. The THOW's width (max 2.5m) and height (max 4.3m) also dictate route planning and potential permit needs.
