Tiny House Rules and Regulations in Queensland

Updated October 2026 | AHA Research Team

Queensland law doesn’t define a “tiny home”. The government splits them into two types: fixed tiny homes for living in permanently, and temporary ones, usually on wheels. A tiny home on wheels used like a caravan is treated as a caravan. To live in any tiny home permanently, it needs the right building approvals. Some councils let you stay in one in a backyard for a set time.

A fixed tiny home in a backyard can be a granny flat (called a secondary dwelling). It may not need planning approval, but it does need building approval, and its plumbing generally needs a permit from your council. You can rent a granny flat to anyone, but renting a tiny home may need council approval, so check first. Size limits depend on your council.

Quick Answers

Apart from very short stays, usually only while you build a house there. The councils we checked only let you live in a caravan or tiny home on wheels on your own land with a temporary home permit while you build an approved permanent home. You’ll usually need building approval for the house, or to be well on the way to getting it. To live in a tiny home on wheels permanently, it needs building and plumbing approval as a home, and may need planning approval.

For short stays, often yes, but it depends on your council. Where it’s allowed without approval, conditions usually apply, such as the main house being lived in, no rent being charged, and no wastewater being left on the property. Longer stays need council approval. For someone to live in it permanently, it needs building and plumbing approval as a secondary dwelling.

Usually about four to six weeks a year, in councils that allow it. Some councils don’t allow any stays without approval, so check your council’s local laws before your guests arrive.

Check first. The Queensland Government describes a tiny home on wheels treated as a caravan as one that isn’t connected to services such as town water and sewer. Living in a tiny home permanently may need building approval and plumbing and drainage approval. Ask your council before you connect it.

Often yes, but it depends on your council. A secondary dwelling that meets the criteria in the Planning Regulation 2017 and your council’s planning scheme, such as size limits, often doesn’t need planning approval. An overlay such as flood or bushfire can change that. You always need building approval and plumbing and drainage approval.

It depends on how you use it. A fixed tiny home always needs building approval (Queensland’s term for a building permit). A tiny home on wheels used like a caravan for short stays generally doesn’t. But if you live in a tiny home on wheels permanently, the Queensland Government says it needs building approval too, plus plumbing and drainage approval.

Tiny house on wheels (THOW)

Quick answer: A tiny home on wheels used for short, temporary stays is generally treated as a caravan. Some councils have local laws that let people live in one in a backyard for set periods. Living in one permanently is different. The Queensland Government says a tiny home that doesn’t meet the definition of a dwelling and doesn’t have the right building approvals isn’t considered suitable for permanent living.

Is it a caravan or a building?

The Queensland Government’s tiny homes guidance says the rules depend on how a tiny home is used and set up.

  • What the law calls a building. Under the Building Act 1975, a building is a fixed structure that is wholly or partly enclosed by walls or is roofed.
  • Used like a caravan. A tiny home that is only used for temporary accommodation and isn’t connected to services like town water and sewer is treated as a caravan, not a dwelling. Caravans are regulated under the Transport Operations (Road Use Management) Act 1995 (Queensland’s road-use law). Councils can also regulate them through local laws.
  • Building standards. A temporary tiny home doesn’t have to be built to the Building Code of Australia (the national building standards) or get planning approval.
  • What makes it a dwelling. Under the planning rules, a tiny home is a dwelling (a home for permanent living) if it is fixed to the land, can be used as a self-contained home, and has a kitchen area, a bath or shower, a toilet, a wash basin and laundry facilities.
  • Living in it permanently. If a tiny home is used for permanent living, whether it’s on wheels or not, and it’s the only home on the block or a secondary dwelling (granny flat), building approval and plumbing and drainage approval may be required. It doesn’t need planning approval if it meets the criteria in the Planning Regulation 2017. Otherwise, it may need planning approval under your council’s planning scheme.

When you don’t need council approval

Each council sets its own rules for temporary homes through local laws, so always check with yours. These are situations where you may not need council approval.

Short stays beside an existing house. Some councils have local laws that let someone stay in a tiny home on wheels in a backyard for set periods without council approval. Time limits and conditions vary between councils. In the councils we checked, conditions included a maximum number of days, a permanent home on the property, access to toilet, bathroom, laundry and water, and proper disposal of wastewater. One also required that no rent is paid and that the council is notified when someone moves in.

Storing an empty tiny home. Depending on your council’s local laws, you may not need approval to store a tiny home on wheels on private land if no one is living in it. Check your council’s rules.

Seasonal workers on farms. Under the Queensland Rural Workers’ Accommodation Initiative, small-scale accommodation for farm workers doesn’t need council planning approval until 16 December 2027, if it meets all the criteria in the Planning Regulation 2017. The land must be in a rural zone, at least 25 hectares, and house no more than 20 workers. No part of the accommodation can be in a flood, bushfire or landslide hazard area. The farm and the accommodation must have the same owner, and there can’t be any new or changed driveway access to the road. Building approval may still be needed. These rules cover rural workers’ accommodation in general, not tiny homes specifically. The Queensland Government says this is a temporary measure while longer-term solutions are worked out with councils.

Told you don’t need approval? Check with your council first.

If a seller or builder tells you a tiny home doesn’t need council approval, check before you buy. Whether yours needs approval depends on your state’s laws, your council’s rules, your property and how you plan to use the home. Get written confirmation from your council, or advice from a town planner, before you sign a contract.

When you need council approval

Living in it while you build your house. Some councils let you live in a tiny home on wheels on your block while you build a permanent home, but you need approval first. In the councils we checked, approvals lasted three to six months, with extensions possible in some cases while building was progressing. Conditions included having a current building or development permit for the permanent home, a minimum block size, and providing basic facilities such as a kitchen, bathroom, toilet, wastewater disposal and a safe water supply.

Living on a block long term. A tiny home on wheels used for temporary stays is treated as a caravan. To live on a block permanently, including a vacant block, the Queensland Government says a tiny home must meet the definition of a dwelling and have the right building approvals (see “Is it a caravan or a building?” above).

Connecting to services. The Queensland Government’s description of a tiny home treated as a caravan includes not being connected to services like town water and sewer. If you plan to connect yours, check with your council about the approvals you’ll need.

Renting it out, running a business, or having more than two. The state guidance says a tiny home, on wheels or not, may need planning approval from your council if it’s rented out as short-term accommodation or leased to a tenant, used as a home office or home-based business, or if there are more than two tiny homes on one property. Building approval and plumbing and drainage approval may also be needed. Some councils’ rules for short stays only apply if no rent is paid.

Towing and registration

Trailers and caravans used on Queensland roads must be registered with the Department of Transport and Main Roads (TMR). To tow an unregistered tiny home on Queensland roads, you need an unregistered vehicle permit from TMR.

Under Queensland’s light vehicle standards, a trailer can be no more than 2.5 metres wide and 4.3 metres high, including any load. The towing vehicle and trailer together can be no more than 19 metres long. Our buying guide covers these limits, plus electric brakes, driver licences and registration, in detail.

Wider than 2.5 metres? To move it on the road, you need a safe movement permit from TMR. The permit sets conditions for the trip, which can include the roads you can use, your maximum speed, when you can travel, warning signs, and pilot or escort vehicles.

If you’re planning a home wider than 2.5 metres, contact TMR about permit requirements and costs before you commit.

Tiny house on foundations

A fixed tiny home (one on foundations, or otherwise fixed to the land) used as a home is a Class 1a building, the building code’s category for houses. Under the Building Act 1975, building work needs a building approval unless a regulation lists it as accepted development, which covers only some minor work. A licensed building certifier assesses the application. This can be a private certifier or one working for your council. The plumbing and drainage for a new building generally needs a permit from your council under the Plumbing and Drainage Act 2018. Depending on your council’s planning scheme, you may also need planning approval.

Backyard tiny homes (secondary dwellings)

A fixed tiny home in a backyard can be a secondary dwelling, the planning term for a granny flat. A secondary dwelling is used together with, and is secondary to, a main home on the same lot, and is generally smaller. It can’t be built on its own. This is different from a dual occupancy, which is two homes on one lot, or on two lots that share things like a driveway, and the two homes can be a similar size. Your council’s planning scheme sets different rules for each, so check which one your plans fall under.

Do you need planning approval? It depends on your council. The Queensland Government says to check with your council whether a new secondary dwelling needs planning approval. Each council’s planning scheme sets its own rules, including how big a secondary dwelling can be. Every new secondary dwelling needs building approval.

Who can live in it? Since 26 September 2022, a secondary dwelling anywhere in Queensland can be rented to anyone, whether or not they’re related to the people in the main house. This change didn’t remove any need for planning or building approval. The state’s tiny homes guidance also says a tiny home leased to a tenant may need planning approval, so check with your council before you rent.

Renting out an existing granny flat? If a granny flat used by your household becomes a rental, extra fire safety and sound insulation requirements of the building code apply. Check with a building certifier before you rent it out.

What the building approval checks

A building certifier checks your tiny home against the building assessment provisions. These include the National Construction Code (NCC, the national building rules) and the Queensland Development Code (Queensland’s own building rules). Key requirements include:

  • Structure and installation: The Queensland Building and Construction Commission (QBCC) advises getting engineering and tie-down details from your supplier (how the home is anchored to the ground) to show it complies with the Building Act and the NCC. A tiny home fixed to the land and used as a home must be installed by a QBCC-licensed contractor, unless you’re an owner-builder with an owner-builder permit.
  • Ceiling heights: Under the NCC’s housing rules, habitable rooms (living areas and bedrooms, but not kitchens) need a ceiling at least 2.4 metres high. In a room with a sloping ceiling, at least two-thirds of the floor area must reach 2.4 metres (or 2.2 metres if it is an attic). Any part of the room lower than 1.5 metres isn’t counted in the floor area. Bathrooms, laundries and similar rooms need at least 2.1 metres.
  • Fire separation: Under the NCC’s housing rules, an external wall must be fire-resisting if it is less than 1.8 metres from another building on the same lot, such as the main house, or less than 900mm from a boundary with a neighbouring property. Windows and other openings in that wall must be protected too. The 1.8 metre rule doesn’t apply to the home’s own garage, carport or shed.
  • Energy efficiency: Most new houses in Queensland must achieve a 7-star energy rating for the building shell (roof, walls, windows and floors). Eligible small homes of 50 square metres or less need 5 stars, and eligible houses with raised floors need 6 stars. A compliant outdoor living area can count for up to 1 extra star. New houses also need a Whole of Home score of at least 60 out of 100, which measures the energy use of major appliances and fixtures, including any solar panels.

A tiny home as your main house

A fixed tiny home can be the only house on your block. In planning terms it’s usually a “dwelling house”, the same as any ordinary home, under the Planning Regulation 2017.

Do you need planning approval? Often not. The Queensland Government says a tiny home used for permanent living, that is the only dwelling on the lot, doesn’t need planning approval if it meets the criteria in the Planning Regulation. Councils can’t require planning approval for a dwelling house that meets those criteria. If it doesn’t, you may need planning approval under your council’s planning scheme. Some councils we checked say your zone, or an overlay such as flood or bushfire, can mean you need planning approval, so check with your council first.

Building and plumbing approval. Like any fixed tiny home, it needs building approval and plumbing and drainage approval. Building approval is given by a building certifier licensed by the QBCC (Queensland Building and Construction Commission). Your council handles plumbing and drainage approval.

Is there a minimum size? The National Construction Code doesn’t set a minimum floor area for a house. A small home must still meet all the same building rules as a standard house.

What’s changing in QLD

Queensland’s housing rules changed a lot in 2026, and some changes are still rolling out. This is what we could confirm as of October 2026.

A new Queensland Housing Code. In August 2026, the Queensland Government released the Queensland Housing Code. It sets statewide design and siting rules for houses and secondary dwellings, such as building height, setbacks, privacy, car parking, site cover and outdoor space. It replaces rules in the Queensland Development Code that date from 2010. Councils can choose to adopt it during a three-year transition period that started on 1 September 2026. If a council hasn’t adopted it by 1 September 2029, it will apply automatically.

What it means for backyard tiny homes. The Housing Code sets a default maximum size for a secondary dwelling: 50m² of internal floor area, or 60m² on lots of 1,000m² or more. Councils that adopt the Code can allow bigger secondary dwellings. A lot with a secondary dwelling also needs a third car space, which can be parked one behind another. Check with your council whether it has adopted the Code and what limits it uses.

Rural workers’ accommodation. A temporary exemption lets farms build accommodation for up to 20 rural workers without planning approval, if strict criteria are met. It ends on 16 December 2027. A separate part of the scheme, for reusing existing buildings nominated by the Planning Minister, ends on 16 December 2026. The Queensland Government says this extension is intended to be final.

FAQs

Tiny home on wheels: Not without checking first. The Queensland Government says leasing a tiny home to a tenant may need planning approval. At least one council we checked doesn’t allow rent to be charged under its local law. Talk to your council before you take on a tenant.

Fixed tiny home (secondary dwelling): Yes, in most cases. A secondary dwelling is a second, smaller home on the same block, like a granny flat. Since 26 September 2022, Queensland’s planning rules no longer limit who can live in one. This change came from the Planning (Secondary Dwellings) Amendment Regulation 2022. You can rent it to anyone, unless your planning approval has conditions about who can live there. If it does, you may need to apply to your council to change those conditions. This is called a change application. You still need all the right approvals. Renting it out can also mean extra fire safety and sound insulation rules apply, so the Queensland Government recommends asking a building certifier before you rent.

Tenancy agreements: If the tiny home is self-contained and the tenant can’t use the main house, you use a general tenancy agreement (Form 18a). If they share the kitchen or other facilities, a rooming accommodation agreement (Form R18) may apply instead. The Residential Tenancies Authority explains both.

Smoke alarms: Rented secondary dwellings must have interconnected photoelectric smoke alarms. Interconnected means they all sound together. Photoelectric means they sense smoke using light. This rule comes from the Fire Services Act 1990, which the Queensland Fire Department administers.

Tiny home on wheels: Not without checking first. Renting to holiday guests counts as “short-term accommodation” in Queensland’s planning rules, which means stays of less than 3 months in a row. Whether you need planning approval depends on your council’s planning scheme. Some councils we checked require planning approval, and some also require a yearly local law licence. We couldn’t find any official source that lets you use a tiny home on wheels as a holiday rental without approval.

Fixed tiny home (secondary dwelling): It depends on your council. Each council’s planning scheme sets its own rules for short-term rentals. Some don’t allow a secondary dwelling to be used for short-term accommodation at all. Others need a planning approval, a local law licence, or both. Check with your council before you list it.

No statewide limit that we could find: Queensland doesn’t appear to have a statewide night limit or register for short-term rentals. The state has looked at a registration system, but we found no sign that one has started.

Smoke alarms: By 1 January 2027, all existing homes in Queensland must have interconnected photoelectric smoke alarms (linked so they all sound together). They must go in every bedroom, on every level, and in hallways that connect bedrooms to the rest of the home. These rules come from the Fire Services Act 1990. The Queensland Fire Department has the full details.

Land valuation: Adding a tiny home, on wheels or fixed, won’t raise your land valuation. In Queensland, land is valued without houses, sheds or other buildings on it. Councils use this valuation to help work out your rates, and the state uses it for land tax. Your valuation can still change each year as land prices change.

Council rates and charges: Your land valuation is only one part of your rates bill. Councils also charge for things like water, sewerage and rubbish collection. Some councils charge these for each dwelling, so a second home can mean extra charges. One council we checked adds an extra rubbish charge for a granny flat, unless a family member lives in it. Check your council’s rates and charges before you build.

Land tax: If the property is your home, you can usually claim the home exemption. You may still qualify if you live there and rent out a granny flat. To qualify, the rented area must be no more than half the total living floor area, and the rent must be no more than market rent. If you don’t meet these rules, you may only get a partial exemption. Exemptions aren’t always automatic, so you may need to apply. The Queensland Revenue Office has the details.

Solar and rainwater tanks: Putting solar panels on a roof doesn’t need building approval, but the work must still meet building rules. A rainwater tank, including its stand, doesn’t need building approval if it covers no more than 10m² of ground, is no more than 2.4m high and has no side longer than 5m. This doesn’t apply to a tank for a new building or in cyclone areas. Check with a building certifier before you install one.

Composting toilets: In areas without sewerage, a composting toilet counts as an on-site sewerage facility, which is a system that treats toilet waste on your property. You need council approval to install one. Composting toilets sold in Queensland must meet the Queensland Plumbing and Wastewater Code. Ask the seller for a written statement that it complies, because your council needs it with your application.

Greywater: Greywater is used water from your shower, bath, basin and laundry. In Queensland, you can reuse it on your garden by bucketing it, but not kitchen water. You can also use a greywater diversion device or treatment plant. These must be installed by a licensed plumber, and most need council approval.

Tiny homes on wheels: We couldn’t find official Queensland guidance on off-grid setups for tiny homes on wheels. Being on wheels doesn’t exempt a tiny home from the Building Act. If you live in one permanently, it generally needs building approval. Ask your council how the toilet and greywater rules apply to your setup.

Common myth:

Going off-grid doesn’t mean you can skip approvals. In Queensland, composting toilets and most greywater systems still need the right approvals. See the Queensland Government’s guide to on-site sewage facilities before you plan your setup.

Tiny home on wheels: Yes. A registered tiny home on wheels can be sold like a trailer or caravan. After you sell it, you must transfer the registration out of your name within 14 days. The buyer pays the transfer fee, and there’s no vehicle registration duty on a trailer or caravan. See the Queensland Government’s guide to transferring a registration.

Fixed tiny home (secondary dwelling): Not on its own. Under Schedule 24 of the Planning Regulation 2017, a secondary dwelling is used together with, and is smaller than, another home on the same lot. To sell it separately, you would need to subdivide your land. In planning terms, this is called “reconfiguring a lot”, and it usually needs a development approval from your council.

What subdividing involves: Each new lot must meet your council’s minimum lot size and other planning scheme rules. You usually pay to connect services like water and sewerage to the new lot, and councils may charge infrastructure charges. In some areas, especially rural land, the minimum lot size is very large or subdivision isn’t allowed at all.

Our “What’s changing” section above covers the new Queensland Housing Code and rural workers’ accommodation. Two other changes started on 14 August 2026 that matter for small homes.

Easier energy rating for small homes: New homes under 50m² now need at least a 5-star energy rating for their building shell, instead of 7 stars. The building shell is the walls, roof, floor and windows. A compliant outdoor living area with a ceiling fan can count for up to 1 star of that rating.

Accessibility rules: New homes still need to meet the livable housing design standards, such as having a step-free entry. There are now more ways to comply. This includes a “ramp-ready” option for raised homes, where the plans show a ramp that can be added later.
