Regulations – Vic Roads trailer regulations (specific to Victoria, Australia)
If you are planning to build a tiny house on wheels in Victoria; In the absence of Tiny House specific regulations the key roadworthiness regulations must follow as the link below.
A summary from Tiny Footprint
- The length of a trailer, other than semi-trailer, should not exceed 12m. Prior to making your decision it will be important for you to decide how the home will be transported as there are restrictions on the maximum length of towing vehicle and what it is towing. If you are considering more than 9m in length, ensure you have made a decision about transport as that may determine other factors. Example if greater than 9m you may wish to transport via a low loader due to overall length restrictions and then your height is best to be under 4.1m to keep the costs contained for moving. (permit costs are higher if over 4.1m and some roads may be restricted to use).
- A registered trailer must not exceed 2.5m in overall width to travel without a special permit. The trailer can go out to 3.5m wide but have a special permit to be moved on the day. The maximum distance measured across the body including wheel guards and support arms, but excluding signalling devices and side mounted lamps.
- The height of any tiny home build must not exceed 4.3m in height, or 4.1m if you plan to move it on a low loader trailer.
- A caravan or trailer equipped with cooking facilities or living or sleeping accommodation must have only outward opening or sliding doors. At least one such door must be located on the left-hand side or at the rear. – tiny footprint note: this is important when taking design ideas from a U.S based plan..
- Definition of Trailer Types based on weight. This is relevant for both trailer ratings required i.e. trailer hitch ball size, trailer brakes and requirements for the vehicle that will pull the trailer. LIGHT TRAILER (TB)—A trailer with a GTM* not exceeding 3.5 tonnes, other than a trailer of Category ‘Very Light Trailer’ MEDIUM TRAILER (TC)—A trailer with a GTM* exceeding 3.5 tonnes but not exceeding 10 tonnes.
*GTM is the weight of the fully loaded trailer imposed on the trailer’s axle when it is coupled to the tow vehicle.
Tip : if you are considering to keep within 8m length and 2.5m wide with a registered trailer, this is the ‘norm’. If you are considering greater than 8m in length and or greater than 2.5m talk to your state road authority and an experienced tiny house building company before making a final determination.
In 2019 Tiny Footprint Pty Ltd is building a tiny house on wheels measuring 12m in length and 3.5m wide and 4.1m in height with a total weight of no more than 8t.
