Tiny home costs and what actually varies by state

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

Published guidance puts a professionally built tiny home at about A$3,500–A$5,500 per m², with entry-level builds from about A$85,000 and mid-range homes at A$120,000–A$160,000; one builder's turnkey prices run from A$101,900 to A$163,900.^[1][2][3] One industry site puts the home itself at only 70–80% of total project cost.^[1] No source located publishes tiny home prices by state, and all of these figures are commercial guidance, not independent survey data.

This guide was planned as a state-by-state price comparison. The research did not support one, and saying so is more useful than manufacturing the table. Tiny homes — particularly those on wheels — are manufactured products sold and delivered nationally, and no source located for this guide publishes Australian tiny home prices broken down by state. What genuinely changes at a border is not the price of the home but the approval pathway, the insurance thresholds, the exposure requirements and the delivery distance. This guide covers the national price picture first, then those variables.

What the published ranges say §

The per-square-metre figure is the one that surprises people. At A$3,500 to A$5,500 per square metre^[1], a tiny home is more expensive per square metre than a conventional house, not less. The reason is arithmetic rather than exploitation: a kitchen, a bathroom, a hot water system and an electrical switchboard cost roughly the same whether they serve 20 square metres or 200, and in a tiny home they are spread across almost no floor area. Tiny homes are cheaper in total and dearer per unit.

Price is driven mainly by length, bathroom and kitchen specification, off-grid systems and the degree of custom design^[2] — which is a useful list, because the first and last are the two most people can actually change.

The number that matters: 70 to 80 per cent §

The single most useful figure located for this guide is not a price. It is that the dwelling price represents only 70 to 80 per cent of total project cost, with the recommendation to add 20 to 30 per cent to the home price for a realistic total^[1].

Published prices are for the home only, before site costs^[1]. A A$100,000 tiny home is therefore a A$125,000 to A$145,000 project, and the difference is not optional extras — it is the land or site arrangement, the connections, the approvals and, very often, an off-grid system.

Indicative figures for those items include around A$25,000 for a remote rural block and A$15,000 for an off-grid setup covering solar, water tank and composting toilet^[1]. Licensed tradespeople are required by law in every Australian state for electrical and plumbing work, at an indicative A$5,000 to A$14,000^[1].

What actually varies by state §

Four things move at a border, and none of them is the manufacturer's price list.

Approval pathway. Whether a tiny home is treated as a caravan, a moveable dwelling, a Class 1a dwelling or a secondary dwelling determines what approvals are needed and what they cost. This differs by state and often by council, and is covered in the tiny home rules guides for New South Wales, Victoria and Queensland rather than here.

Licensing and insurance thresholds. For a fixed tiny home built by a contractor, the statutory insurance obligation starts at very different points. New South Wales requires a licensed building contractor with Home Building Compensation Fund insurance for projects over A$20,000; Victoria requires a registered domestic builder with domestic building insurance for work over A$16,000; Queensland requires a QBCC licensed builder with home warranty insurance mandatory for projects over A$3,300^[5].

That last figure is the one to notice. A Queensland fixed tiny home almost certainly falls inside the warranty scheme; a Victorian or New South Wales project of the same value may or may not, depending on where the contract price lands. The insurance is a cost, and its absence is a risk — see Building insurance and warranty schemes by state.

Exposure requirements. Cyclone-rated construction is required north of the Tropic of Capricorn in Queensland^[5], and bushfire attack level requirements apply on many sites in the southern states. Both change the structure rather than the finishes, and both are priced into a build rather than added to it.

Delivery. A tiny house on wheels is built in one place and towed to another. Distance from the manufacturer is a real and state-dependent cost that no national price list includes, and it is the most common reason a quoted price and a delivered price differ.

The DIY route, honestly §

Building your own is the cheapest path on paper and the most expensive in ways that do not appear in a budget. One documented DIY builder spent A$45,000 on materials — but the account also records a year off work and significant family support^[1].

Licensed electrical and plumbing work cannot be self-performed regardless of skill^[1], so a DIY build is always a partial DIY build. Anyone comparing a A$45,000 materials figure with a A$100,000 turnkey price is comparing two numbers that measure different things.

What is not covered here §

No independent Australian survey of completed tiny home project costs has been located for this guide, and no source located publishes tiny home prices by state. The ranges above are published by builders and industry sites with a commercial interest, and describe their own products and service areas.

Land and site costs vary enormously and are not covered beyond the indicative figures given. Ongoing costs — site fees, insurance, registration, maintenance — are not covered here; registration fees as published by state governments are in Tiny home on wheels running costs. Resale values for tiny houses on wheels are not covered by these sources, and the general point about tenure and resale is made in Valuation and resale of modular homes.
