Tiny Home Industry 2025 — Australia
Tiny houses have moved from fringe to feasible. With affordability stretched and build times blowing out, Australians are turning to tiny homes on wheels (Tiny homes on Wheels), modular builds and kit homes as faster, lower‑cost paths to a roof over their head. Here’s the state of the industry, what’s changing in regulation and finance, and how to make a plan that actually works.

2025 snapshot
Demand is still rising. Builders report faster pipelines for modular and prefab homes (10–16 weeks in factory, then weeks on site), and even architect‑led flat‑pack systems are cutting cost and time by assembling in days, not months. Savvy buyers are using tiny homes as backyard second dwellings, regional retreats or stepping stones out of the rent trap. Savings versus conventional builds vary by spec, but factory control and repeatable components keep prices predictable. Supply chains are also less weather‑exposed, reducing the variance that plagued on‑site builds through 2022–24.
What’s driving it? Affordability pressures, rental scarcity, and the appeal of energy‑efficient, off‑grid capable designs. Meanwhile, local councils are experimenting with policy: some now run tiny‑home pilots or have removed minimum house sizes, while others still limit stays unless approvals are in place. Expect regulation to keep evolving through 2025–26 as states reconcile planning, building and road rules. The standout shift this year is in finance: major‑bank support for prefabricated, off‑site construction has opened cleaner funding paths for permanently installed modular homes, accelerating adoption where land and services are available.
On the ground, the market is segmenting. Tiny homes on Wheels continue to suit flexible living, farm stays and backyard accommodation where local rules permit shorter occupation or specific approvals, while fixed modular/kit dwellings are the route to mortgage‑style finance, long‑term tenure and compliance with NCC standards. For buyers, the winning playbook is simple: secure written council guidance early, pick a reputable manufacturer, lock a fixed‑price contract with clear milestones, and structure finance to draw in stages — reducing cash‑flow pain without compromising build quality.
Build types: Tiny home on Wheels, modular and kit
Tiny home on Wheels: Built on a trailer to road‑legal limits (typically up to ~2.5m wide, 4.3m high, 12.5m long and 4.5t), towable and relocatable. Best for flexibility and speed, but financing is different to a standard mortgage and long‑term parking depends on local rules.
Modular/prefab: Built to ~90–95% completion in a factory, transported in sections and finished on site. Advantages include time certainty, weather‑proof production, and agreed scope/cost. Good fit where you have land and want a code‑compliant, permanent dwelling.
Kit homes: Materials arrive as a kit; you owner‑build or engage trades. This can dramatically reduce cost if you coordinate trades well, and suits capable DIYers or buyers with family/friend networks in the trades. Consider your time, compliance obligations and contingency budget.
Regulations: a patchwork (for now)
Rules span three layers: road (towing sizes/weights), building (NCC compliance if fixed) and planning (where you can put it and for how long). Fixed tiny homes are assessed like any small dwelling and must meet the National Construction Code as a Class 1 building; Tiny homes on Wheels generally fall under caravan/movable‑dwelling frameworks and are not assessed under the NCC unless fixed or certified as permanent.
Policy is shifting. Some councils have released tiny‑home guidance; stays beyond short, temporary limits typically trigger approvals under state movable‑dwelling regulations. Keep an eye on NCC 2022 amendments and state transitional arrangements as they flow through 2025.
Finance & lending: what actually works
Mortgages on the tiny home itself? Not for Tiny homes on Wheels. Without land security and a building classification, mainstream home loans aren’t available. If you own land and are building a fixed tiny home as a compliant dwelling, standard construction/renovation loans may apply—subject to lender policy, valuations and minimum loan sizes.
Personal/asset loans (most common for Tiny homes on Wheels): Many borrowers combine two or three unsecured personal loans (often $50–$60k caps each, sometimes higher via builder‑linked finance) staged to build milestones, avoiding paying all interest while the build is underway. Lenders will assess income, credit history and existing debts; beware “caravan” loans mis‑sold for tiny homes—the VIN will often reveal it’s just a trailer, and limits/pricing may be worse than a well‑structured unsecured blend.
Equity release: If you have a conventional home, a modest top‑up to ~80% LVR can be the cleanest funding path, avoiding LMI and high unsecured rates. Rural/undeveloped blocks are harder: banks often dislike sub-$150k mortgages, restrict LVRs to ~50–60% on certain zonings, and may avoid vacant land without a build plan. Specialist or private funding exists but costs more.
CBA’s flexible prefab construction policy (new in 2025): Commonwealth Bank now supports progressive funding during the off‑site build for prefabricated homes. Customers with a fixed‑price contract (up to around $1.5m) can access progress payments before the home is affixed to land — typically up to 60% of the contract price, or up to 80% when building with a CommBank Assessed Manufacturer. The policy is designed to solve the historic cash‑flow gap for modular builds and gives borrowers clearer, mortgage‑style pricing and staged drawdowns tied to manufacturer milestones. It does not apply to Tiny homes on Wheels used as movable dwellings, but it’s a significant step forward for factory‑built homes intended to be permanently installed on land.
Where can I put one?
Common legal pathways include: (1) as a secondary dwelling/granny flat on land where your planning scheme permits it (fixed build to NCC, approvals required); (2) as a movable dwelling under caravan/camping rules for short stays or with council approvals for longer occupation; (3) in a caravan park, lifestyle or manufactured-home estate that accepts tiny homes; or (4) on rural land where local planning allows temporary or additional dwellings.
Because rules differ by council, pre‑application meetings and written advice are gold — don’t move a Tiny home on Wheels in and hope.
Tip: Check services (power/water/waste), bushfire and flood overlays, and road access for delivery. Even relocatable homes need compliant connections and setbacks. If you’re off‑grid, budget for solar, batteries, rainwater and wastewater systems sized to the occupants and local climate.
FAQs
How much does a tiny home or kit/modular cost in practice?
Ranges are wide, but kit shells can start from tens of thousands for simple studios, while full modular homes price more like conventional builds. Factory build plus on‑site completion compresses timelines and reduces weather risk; owner‑building a kit can save if you manage trades well and stay compliant.
Can I live in a Tiny home on Wheels full‑time?
Often not without approvals. Many councils treat Tiny homes on Wheels like caravans: short, temporary stays may be allowed without approval, but long‑term residence usually needs consent or a clear planning pathway. Always check the local planning scheme and any tiny‑home policies in writing before you buy.
Can I get a normal mortgage?
Only if the home is fixed and assessed like a Class 1 dwelling on land you own with appropriate tenure. Tiny homes on Wheels aren’t mortgageable assets by themselves. Most Tiny home on Wheels buyers use a mix of personal loans, equity release, or, less commonly, specialist/private funding that trades off cost for flexibility.
What about road‑legal size and weight?
For towing without oversize permits, builders typically target about 2.5 m width, 4.3 m height, 12.5 m length and a 4.5 t maximum laden weight. Always confirm your design meets the limits in your state and factor vehicle towing capacity, brakes and licensing before committing to a build.
How do I de‑risk my project?
Get written council advice early, lock a fixed‑price contract, stage loan drawdowns to build milestones, allow a 10–15% contingency, and plan services or off‑grid systems with compliance in mind. If you own a home, compare an equity top‑up to unsecured blends — cleaner structure, lower rates and simpler repayments.
Does CBA’s prefab policy cover Tiny homes on Wheels?
No. CBA’s flexible construction policy targets prefabricated homes that will be permanently affixed to land under a fixed‑price contract. Tiny homes on Wheels are treated as movable dwellings and typically don’t qualify for mortgage‑style construction lending. If you’re set on a Tiny home on Wheels, compare equity top‑ups and staged personal‑loan blends.
How do progress payments work with assessed manufacturers?
With a fixed‑price contract, CBA can release funds during the off‑site build. Typical settings allow up to roughly 60% of the contract before installation — or up to 80% if you use a CommBank Assessed Manufacturer. Draws are tied to factory milestones and verified invoices, easing cash flow during production.
What insurance and warranty checks should I make?
Confirm the builder’s home warranty/defect cover, factory QA, and transport/cranage insurance. For fixed homes, ensure NCC compliance, engineering sign‑off and connection certificates. For Tiny homes on Wheels, check trailer VIN, braking and weight compliance, plus park/council permissions. Keep certificates and manuals — finance, insurance and resale depend on documentation.
