Tiny home rules in Western Australia

From Modular Living Australia — the independent knowledge base Last updated: 8 Oct 2026

In Western Australia a tiny home on wheels is regulated under the Caravan Parks and Camping Grounds Regulations 1997, and the term "tiny home" is not defined in WA legislation.^[1][4] It can be lived in on private land for up to five nights with the property owner's approval, and since 1 September 2024 for up to 24 months with local government approval, which can be renewed; without an approval or exemption, using it outside a licensed caravan park risks committing an offence.^[1][2]

Western Australia changed its tiny home rules more decisively than any other Australian jurisdiction. On 1 September 2024, amendments to the Caravan Parks and Camping Grounds Regulations 1997 extended the period a local government can approve someone to live in a caravan or tiny home on wheels on private land from three months to 24 months, renewable.^[1]

That is a genuine shift, but it is easy to over-read. It did not create a right to live in a tiny home; it extended a discretionary approval power that local governments already had. The decision still rests with your shire or city, and the structure is still legally a caravan, not a house.

The starting point: caravans belong in caravan parks §

WA legislation generally restricts the use of caravans to licensed caravan parks, where a minimum level of services and utilities must be supplied. Using a caravan or tiny home on wheels outside a licensed park without an approval or exemption risks committing an offence — and that applies whether the land is private or public.^[2]

Everything below is an exception to that rule, not the rule itself.

The three tiers §

Before 1 September 2024 the ceiling was three months, or up to 12 months where the arrangement was in a caravan and the occupant held a building or demolition permit — and anything longer than three months required a separate application to the Minister for Local Government.^[3] The reform moved that decision down to the local government and lengthened it eightfold.

Conditions come with the approval §

A local government that grants an approval may attach health and safety conditions. Published guidance gives the example of requiring the applicant to have sufficient power, water, sewage and cooking facilities.^[2]

This is the practical crux for anyone buying a tiny home to live in long term. A structure that cannot demonstrate a lawful wastewater arrangement is unlikely to satisfy a condition of that kind, whatever the brochure says.

If the local government refuses an approval or revokes one, the Minister for Local Government retains the power to consider the approval.^[2]

What the regulations cannot do §

The camping regulations approve occupation, not construction. Published guidance is explicit that the construction of a building or permanent structure on the land is generally subject to planning or building approval and cannot be approved under these regulations.^[2]

In other words, the moment a tiny home stops behaving like a vehicle — fixed to the ground, hard-plumbed, decked in — it stops being covered by this pathway and becomes a building, assessed like any other building.

"Tiny home" has no legal definition in WA §

The state's own guidance acknowledges the underlying problem: tiny homes are built in a variety of ways, which leads to confusion about which legislation applies, because the term is not defined anywhere in WA legislation.^[4]

That means the classification of any particular product is a question of fact about how it is built and used, not a question of what it is called. Two units marketed identically can fall on opposite sides of the line.

Road limits still apply §

A tiny home on wheels only remains a caravan in any practical sense if it can actually travel. Published guidance puts the standard road limits at about 4.3 m in height, 2.5 m in width and roughly 9 m in length for travel without special permits.^[5] Beyond those dimensions an oversize permit is needed for each move — see delivery, transport and craneage.

The alternative: a fixed ancillary dwelling §

For anyone who wants a permanent second dwelling rather than a renewable approval to camp, WA's granny flat pathway — an ancillary dwelling — is the other route, and it produces a building with an approval rather than a vehicle with a permit. It is covered separately in granny flat rules in Western Australia.

The trade-off is straightforward. The camping pathway is cheap, fast and impermanent. The ancillary dwelling pathway is slower and costs more, and results in an approved dwelling that does not have to be renewed.

Questions to ask your local government §

1. Will you grant a temporary accommodation approval at this address, and for how long?
2. What conditions do you attach — specifically on wastewater, water and power?^[2]
3. What is the fee, and what is the renewal process at the end of the term?
4. Is there a local planning policy for tiny homes on wheels in this district?
5. If I later fix the unit to the ground or connect it to services, what approvals does that trigger?^[2]
