You can buy a tiny house on wheels in South Australia, register it as a caravan through Service SA and tow it wherever you like. That part is simple. What happens when you park it on a block and start living in it is not.
South Australia has no tiny house approval pathway. What it has instead is the Planning, Development and Infrastructure Act 2016, the Planning and Design Code, and council officers who each have to decide whether your tiny home is a parked vehicle or a change in the use of the land. Those two answers lead to very different outcomes.
We build tiny houses on wheels in East Lismore, New South Wales, and deliver Australia wide including into Adelaide and regional South Australia. What follows is the position as we understand it in 2026, with sources named so you can check them.
Can you live in a tiny house in South Australia
The honest answer is that it depends on your council and on how permanent your setup looks.
Guidance published by the Department for Infrastructure and Transport, titled Ancillary accommodation, caravans and moveable housing, is the clearest statement of the state position we have found. It says a caravan requires development approval where it “is being occupied on vacant or unused land or where the caravan is permanently fixed to the land”. Parking a caravan on a residential property where someone already occupies the house does not require approval, provided the caravan stays parked rather than fixed to the ground.
Read that carefully, because the distinction is doing a lot of work. A caravan sitting behind your house is fine. A caravan that somebody lives in, on a vacant block, is not.
The same FAQ deals with tiny houses on wheels separately, describing them as small scale accommodation buildings, usually on wheels and moveable, used as permanent or semi permanent residential accommodation. That framing matters. Under the Planning, Development and Infrastructure Act 2016, development includes a change in the use of land as well as building work, so a permanent residential use can trigger approval even when no concrete is poured.
There is one clear exception. Where a home has been damaged by flood or bushfire, state guidance allows temporary accommodation in a caravan for a period not exceeding two years, or until a new dwelling can be occupied, whichever comes first.
What the rules actually say
Registration. A tiny house on wheels is a light trailer if its aggregate trailer mass is under 4.5 tonnes. South Australia changed its trailer rules on 1 July 2023, and from 1 September 2023 a trailer must have an entry on the Register of Approved Vehicles before it can be registered. We manufacture our own trailers in house and deal with that compliance chain, so the registration through Service SA is straightforward. All of our homes are 2.5 metres wide, the standard legal limit, so width alone never requires an oversize permit.
What turns a vehicle into a building. State guidance identifies three triggers for building work: connection to the ground through stumps, piers or footings, connection to services such as drains and water lines, and attached permanent structures such as decks and verandahs. Keep the wheels on, use flexible connections and keep any deck free standing, and you stay on the vehicle side of the line.
Wastewater. On site wastewater in South Australia is regulated under the South Australian Public Health (Wastewater) Regulations 2013, administered by councils. Any connection into a septic system or a common effluent scheme is wastewater work and needs approval in its own right.
Ancillary accommodation is a different animal. The Planning, Development and Infrastructure (General) (Ancillary Accommodation and Schedule 6A) Amendment Regulations 2023, gazetted on 16 November 2023, loosened the rules on who may occupy a granny flat. Useful reform, but it applies to fixed buildings needing planning consent and building consent and assessed as Class 1a under the National Construction Code. It is not a pathway for a tiny house on wheels.
Time limits. Outside the two year disaster provision we are not aware of a statewide occupancy limit for a caravan on private land in South Australia. Anyone quoting you a fixed number of days is guessing. Ask your council in writing.
Council by council reality
City of Onkaparinga publishes one of the more direct pages in the state, titled Granny flats, tiny homes and caravans. Asked whether a tiny home on wheels needs approval, the council answers yes, “as it is considered development”, because there has been a change in the use of land or building work. It confirms a privately owned caravan parked on a residential property does not need approval provided it is not fixed to the land, and repeats the two year limit for temporary accommodation after flood or fire damage. Looking south of Adelaide, read that page first.
Adelaide Hills Council is a harder read, because the real constraint there is bushfire. Much of the council area sits under the Hazards (Bushfire Risk) Overlay in the Planning and Design Code, which changes what is assessable and what conditions attach. As at 2026 the council publishes no dedicated tiny house page, so call the duty planner with your address and ask directly.
Mount Barker District Council covers a lot of large rural living allotments where a second dwelling is a live question, but again nothing is published in tiny house specific form.
We will say the awkward thing plainly. No South Australian council we are aware of has published a tiny house approval pathway of the kind Tasmania has. Some officers are pragmatic, some are not, and the difference between a good outcome and a bad one is usually whether you asked before you arrived.
Getting a tiny home to South Australia
It is roughly 1,900 kilometres by road from our East Lismore workshop to Adelaide, usually run out through the Newell and Sturt Highways. We quote delivery per job, because the number depends on the model, the route and the season.
Distance is rarely the problem. Site access is. A 9.5 metre home on a trailer needs a swept path to get where it is going, and Adelaide Hills driveways are steeper and tighter than they photograph. Before you pay a deposit, send us pictures of the entry, the gate width, any overhead branches and the final standing spot. We would rather tell you it will not fit than find out on the day.
Which of our models suits South Australia
7.4m Spirit, from $123,000. The obvious choice for a suburban back yard in Adelaide behind an existing house, where the whole exercise depends on fitting down a side access and not dominating the block.
8.4m Haven, from $165,000. The middle of our range. It gives you a proper separate bedroom without becoming a difficult tow, which matters on a 1,900 kilometre delivery.
9.5m Grand, from $165,000. For rural blocks in the Barossa, the Fleurieu, the Riverland or the Mid North where access is generous and you want the extra length for living space rather than storage.
Climate should shape your specification more than your model choice. Adelaide summers are hot and dry, and the Riverland and Yorke Peninsula hotter again, so insulation, shading and cross ventilation earn their keep. Solar is worth costing early if the block has no mains power, and rainwater storage is close to essential on rural land.
Frequently asked questions
Can I legally live in a tiny house in Adelaide?
You can own one and register it as a caravan through Service SA. Living in it long term on a block is treated as development under the Planning, Development and Infrastructure Act 2016, because it is a change in the use of the land. The Department for Infrastructure and Transport FAQ says a caravan occupied on vacant or unused land, or fixed to the land, needs development approval. Ring your council before you buy.
How long can a caravan or tiny house stay on my land in South Australia without approval?
There is no single statewide number. State guidance says a caravan simply parked on a property where the house is occupied does not need approval, provided it is not fixed to the land and nobody is living in it. Once it becomes someone’s home, the position changes. Councils enforce this differently, so confirm the local view in writing.
Does my tiny house need to be registered in South Australia?
If it is on wheels and you want it road legal, yes. It is a light trailer under 4.5 tonnes aggregate trailer mass. Since 1 September 2023 the trailer must have an entry on the Register of Approved Vehicles before Service SA will register it. We manufacture our own trailers and handle the compliance side so the paperwork is in order when it arrives.
What happens if I connect the tiny house to water and sewer?
Connecting to services is building work under state guidance, and on site wastewater is regulated by the South Australian Public Health (Wastewater) Regulations 2013 through your council. That connection is usually what turns a registered caravan into a building in the council’s eyes. Most owners use a flexible connection and a portable or holding tank arrangement instead.
Is a tiny house on wheels the same as ancillary accommodation?
No. Ancillary accommodation, what most people call a granny flat, is a fixed building that needs planning consent and building consent and is assessed against the National Construction Code. A tiny house on wheels is a registered vehicle. They are two different approval pathways, and a council that says yes to one may still say no to the other.
Can I put a tiny home on a bushfire prone block in the Adelaide Hills?
The Hazards (Bushfire Risk) Overlay in the Planning and Design Code applies across much of the Adelaide Hills and it changes what is assessable. A registered caravan is not assessed under the bushfire building provisions, but access, water supply and where you park it will all matter to the council and to your insurer. Get advice from the council before you commit.
How much does it cost to get a tiny home delivered to Adelaide?
Delivery is quoted per job because it depends on the model, the route and the site. It is roughly 1,900 km by road from our workshop in East Lismore to Adelaide. The bigger cost risk is usually the last hundred metres, not the first 1,900 kilometres. Send us photos of the driveway and we will tell you straight if it is a problem.
