Do I need a planning permit for a granny flat in Victoria?
Victoria lets a small second dwelling of up to 60 square metres be built without a planning permit in most cases, where no flooding, environmental or other special planning controls apply.[1] A building permit is still required.[1]

What Modular Living AI covers §
Modular Living AI answers questions about factory-built housing in Australia — modular homes, prefabricated and kit homes, granny flats, tiny homes and transportable homes — across New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania, the Australian Capital Territory and the Northern Territory. It draws on the guides in these topics, and on the Australian government pages those guides cite — planning departments, building regulators, revenue offices and national bodies such as the Australian Building Codes Board and the Australian Taxation Office. Answers label each source as one of our guides or an official source.
You can ask in any language. Questions in other languages are translated into English, answered and checked in English, then translated back; if the translation changes or drops any number or citation, the checked English answer is shown instead. Sources stay in English.

Limits and privacy §
Modular Living AI has a daily usage limit. When the limit is reached, or the AI is unavailable, you see matching guides from site search instead. Answered questions are not stored. Questions it cannot answer are saved without anything that identifies who asked, so we can see which guides to write next — see Privacy.
What is not covered here §
This page describes the assistant only. It does not cover builder recommendations, personal advice, or any topic our guides do not yet cover; for those, the guides index and editorial policy explain what the site does and does not publish.
