South Australia

State level

South Australia treats tiny homes as ancillary accommodation, requiring both planning and building approval under the Planning, Development, and Infrastructure Act 2016. Under this framework, mobile tiny homes may be treated as caravans with associated time limits on occupancy, while fixed dwellings must meet building codes and may need planning approval. Uniquely, South Australia allows tiny homes to be self-contained, though they must remain subordinate to the main dwelling and share utility connections. These structures must also be appropriately sited to avoid negative impacts on neighbours and meet National Construction Code safety standards. At the state level, the Department of Planning, Transport and Infrastructure oversees both building administration and road rules for tiny homes on wheels, meaning registration and transport requirements are also governed centrally.

Local Government level

At the local government level, the regulatory picture becomes considerably more varied. Individual councils have jurisdiction to interpret planning rules, and prospective tiny home owners need to understand the planning scheme and regulations that apply to their specific council area. South Australia has a broadly progressive stance on tiny homes, with some councils showing support - though permanently downsized homes must still comply with the Building Code of Australia and local planning laws.

For example, the City of Onkaparinga has published specific guidance on tiny homes and granny flats, and Adelaide Hills Council is among those leading the way in embracing tiny homes at a local level.

Because regulations can differ so significantly between councils, it's important to contact your specific local council directly before purchasing or placing a tiny home. As councils differ in their laws around caravans - which is often the classification applied to tiny homes on wheels - it's not possible to make a broad statement about what will be approved or not.

Key questions to ask your council include how they classify the structure (caravan, secondary dwelling, or relocatable home), whether a development approval is required, and what time limits, if any, apply to occupancy.
