FAQs: Tiny homes in Queensland unpacked

For the purposes of this document, the term tiny homes can refer to:  

• prefabricated pods and modular units
• flatpack or kit studios
• transportable or relocatable buildings
• small prefabricated Class 1a dwellings (single dwellings including houses, attached houses, row houses or townhouses)
• modular homes
• prefabricated or prefab homes
• transportable homes
• relocatable homes
• granny flats or secondary dwellings
• backyard studios or pods.

These structures are usually manufactured off‑site and then delivered, assembled, or installed on a residential property.  

Yes. Tiny homes are subject to the same planning, building and plumbing laws that apply to traditional homes. This includes meeting National Construction Code requirements and obtaining all necessary approvals before purchase or installation.

Before purchasing or installing a tiny home, home owners should:

• contact their local council to confirm planning and zoning requirements
• engage a private building certifier to identify the approvals needed and Class 1a compliance pathway, such as planning, building and plumbing
• treat the project like any home construction by planning for site access, services and engineering
• request documentation from the supplier, including engineering, tie-down details and product information to ensure full compliance with the Building Act 1975, the National Construction Code (NCC) and the Building Code of Australia (BCA)
• keep copies of approvals, certificates, contracts and warranties for future reference.

Proceeding without approvals can be costly and lead to enforcement action and penalties, including by your local council.  

A tiny home that is fixed to land and used as a dwelling must be installed by an appropriately licensed contractor.

In Queensland, installing a tiny home is residential construction work when the structure:

• is fixed to the ground (for example, by footings, tie‑downs or service connections), and
• is intended to be used as a Class 1a dwelling.

In these circumstances:

• installation must be carried out by a QBCC‑licensed contractor
• a home owner cannot install a tiny home themselves unless they are acting as an owner builder and hold the required owner builder permit
• owner builders are not eligible for Queensland Home Warranty Scheme (QHWS) cover for the overall build or installation.

If a tiny home remains on wheels and is not fixed to land or connected to services, it may fall outside building laws (see Question 7). 

Yes. QHWS may apply to tiny homes and other prefabricated or flatpack homes, but only for on-site residential construction work (including installation). It does not cover off-site manufacturing or defective products or installed by an owner builder.  

Covered by QHWS (generally):

• On-site installation and related building work (e.g. footings, service connections, assembly).
• Defective on-site installation work and resulting damage.
• Completion of unfinished on-site installation work (in relevant circumstances).

Not covered by QHWS:

• Off-site prefabrication/manufacture of the home or components.
• Transport/delivery of the prefabricated structure to site.
• Defective products/materials (including faults in the prefab/flatpack home itself), even if supplied and installed under one contract. Owners would need to seek remedies under Australian Consumer Law (ACL), through the Office of Fair Trading, and/or any manufacturer warranties.
• Where a tiny home is assembled by the home owner as an owner builder, QHWS does not apply to the overall build, even if licensed contractors are engaged for individual components (see Question 6). 

If you engage a QBCC-licensed contractor to install it:

• The installation contract is considered a contract for residential construction work.
• The contractor must take out QHWS cover for:  
  • the value of their installation contract, plus
  • the value of the materials (including the flatpack itself).

If the contractor fails to start the work:

• You may be entitled to a refund of the lawful deposit:  
  • 5% for installation contracts over $20,000
  • 10% for smaller contracts.

Note: This applies only when the contract is fixed price and was ended due to the contractor’s default.

If the contractor starts but doesn’t finish:

• You may be entitled to a QHWS claim to:  
  • complete the installation, and
  • fix any defective work that may have already occurred.

If the installation is defective:

• the QHWS covers the defective installation and damage caused by it
• the QHWS does not cover defects in the flatpack home itself. 

If you assemble the tiny home yourself (as an owner builder):

• It does not apply, even if you hold an active building licence or trade qualifications. See questions 3 and 4 above for more information.  

If you engage licensed contractors for specific work:

• Any licensed contractor you engage (such as a plumber) must take out QHWS insurance if their contract value exceeds $3,300.
• That insurance only covers defects in that contractor’s work. 

Yes.  

A tiny home on a trailer with wheels that is not fixed to land or connected to utilities is treated as a caravan and is regulated under transport and vehicle registration rules rather than building laws.  

Once fixed to land and used as a dwelling, it becomes a Class 1a building and must meet all building, planning and plumbing requirements. 

Installers should:

• hold the correct QBCC licence for the type of work they are carrying out
• make sure installation work meets all planning, building and plumbing requirements (see question 2)
• take out QHWS cover for building work valued at more than $3,300, including for installation of prefabricated or flatpack homes
• ensure installation work is completed to the standards expected under the QBCC Act and NCC
• rectify any defective installation work. 

Individual building products that contribute to the make-up of the building (e.g. windows, plumbing products, smoke alarms) are subject to NCBP laws.

NCBP laws apply to everyone involved in supplying or installing building products, including suppliers, manufacturers, importers and installers. This means every party in the supply chain has legal responsibilities to ensure the materials and components used in a tiny home:

• are safe
• meet relevant regulatory requirements
• are capable of performing as represented.

If a tiny home contains a non‑conforming building product, action may be taken against any responsible party, not just the installer. These laws apply regardless of whether the home is constructed traditionally on‑site or delivered as a flatpack or prefabricated structure.  

If the issues relate to something other than NCBP laws (such as the quality or damage to the product), consumers may also have rights under Australian Consumer Law, and complaints can be made through the Office of Fair Trading or the ACCC.
