Question: are tiny houses legal in australia?
Answer: From the ground to the roof, you can't go any higher than 4.3 metres and no wider than 2.5 metres. As for length, tiny homes can go up to 12.5 metres, but chances are you won't want it that long anyway. “The reason being to legally tow it on Australian roads, you need to keep it under 4.5 tonnes,” Darren said.
