- Plumbing and Building Regulations
The Tiny House Approval Flow Chart provides an overview of common tiny house occupancy scenarios. The first question on that chart is “do you own the land?” As a land owner, you can make applications to and apply for permits from your local government. If you don’t own the land, then you will need the owner’s consent to make applications or apply for permits.
General enquiries about a land parcel can be made by anybody, so you can find out about planning policies, applicable overlays, local laws and other regulations without needing the landowner’s consent.

A tiny house is a dwelling of no more than 50m2 built on a wheeled trailer base, constructed of domestic grade materials and finishes, that is capable of being permanently occupied.
A tiny house cannot (and is designed not to) be moved under its own power and is designed and built to look like a conventional dwelling.
ATHA’s definition of a tiny house does not relate to permanently fixed smaller sized homes on foundations. A house on fixed foundations, of any size, can be assessed under the National Construction Codes.
Tiny houses on skids (THOS) are likely to be in this category too.
The application and enforcement of planning policies and building codes in Australia is managed by local government, within overarching state frameworks.
Tiny Houses on Wheels (THOW) are not transportable homes currently covered under building regulations nor are they a recreational vehicle such as a caravan, yet they may be connected to a trailer base. If not on foundations THOW are not “buildings” for the purposes of current state and territory laws or building codes.
Many local government areas currently classify a THOW as a caravan by default, thus limiting their use to temporary occupation, often with restrictive conditions.
THOW are not usually recognised in national vehicle regulations as caravans or recreational vehicles, but they can be built on trailers that comply with Vehicle Standards Bulletin 1 (VSB1) for dimensions and weight as "loads".

Tiny Houses on Skids (THOS) are currently likely to be considered as buildings, even if they are only temporary.

A retrofitted bus, van or truck, wagon, retrofitted sea container, caravan, tent, yurt, non-retrofitted vehicle or ‘donga’ transportable or park home, is not a tiny house for ATHA’s purposes.

“The right zoning balances productive use and protection of neighbours and sensitive environments.”
Intensive use zones such as those for industry need to be buffered from residential zones and sensitive environments. Productive rural land will often have policies that limit the extent of buildings on a property.
Residential zones include a range of allowable densities - from high-density apartments to low-density detached houses and rural-residential land. Non-residential zones generally cannot contain dwellings, except in specific cases.
When looking at land options, first check the local government website for planning and development information where you can search by street address or property description. You will also encounter overlays (flooding, bushfire, heritage, biodiversity) that supplement zoning and help manage risks.
Some councils are complaint-driven—if a complaint establishes legal non-compliance (for example, more dwelling units than allowed), Council must act to enforce the law.
“Overlays like flooding or bushfire can change what is allowed on the same piece of land.”
Planning policy is about managing impacts on neighbours and the environment. The aim is to achieve orderly and sustainable development. This is primarily achieved by a land zoning scheme combined with a set of policies that govern development within each zone. Intensive use zones such as those for industry need to be buffered from residential zones and sensitive environments for example. Productive rural land will have policies that aim to preserve that use by limiting the extent of buildings on a property as another example.
Zones for residential use will include a range of allowable densities, from high density apartment towers, through medium density townhouses, low density detached houses to very low density rural-residential or “acreage” land. Non-residential zones cannot contain dwellings, perhaps except for a single caretaker’s unit in some cases.
Lower density residential zonings quite often limit a parcel of land to housing a single-family unit, or a restricted number of unrelated people cohabiting (a group house). We are seeing an increase in the acceptance of a secondary dwelling (granny flat) in these zones in several States, which is potentially good news for tiny houses and housing supply generally.
When looking at land options, first check the local government website for a planning and development information section where you may be able to perform a property search to find out the zoning and the applicable zoning policies for a particular plot of land. You will usually need a street address or real property description (RPD) for such a search. Some search tools are map based, avoiding the need to enter an address or RPD.
When searching for planning information on a property you will likely also encounter land “overlays” that supplement the zoning, for example flooding or bushfire hazard, among others. Land in the same overall zoning may be subject to different overlays. Overlays are there to help understand and manage impacts and risks, for example; heritage, biodiversity, habitat, bushfire or flooding.
We are aware of tiny house owners being issued with eviction notices, even on large rural allotments where there seems to be plenty of space. In some of these cases there have been three or more “dwelling units” on the same property. If the zoning policy only allows for a primary residence and possibly a secondary dwelling, but not “multiple dwellings”, Council has a legal obligation to insist on the removal of excess dwelling units.
Some Councils are complaint-driven, meaning they only act if a complaint is made, they don’t go around looking for non-compliance. Once a complaint has been made and it is established as being legally valid, Council must act to enforce the law.
Tip: To avoid falling foul of planning policy, be informed about the land zoning, applicable overlays and the policies that follow from these for your parking spot. Also be aware of your potential (real or imagined) impacts on neighbours. If they can see your tiny house, they may start asking questions with the Council about whether it has a right to be there.
“Development” has a specific meaning in planning schemes and there will be subtle differences from location to location, but the general meaning is anything that changes the landform or land use is development.
All development will trigger planning assessment, but some development is “self-assessable” or “as of right”.
Fencing, clothes lines and small garden structures are examples of development that typically does not require making an application or notifying Council. In such cases, it is up to you to understand the rules and make sure that you comply.
All other development will typically trigger an additional level of compliance assessment. This may simply mean lodging a form with Council or obtaining sign-off from a Building Certifier. The general rule is, the higher the potential impact, the more complex (and costly) a development application becomes. A proposal for multiple dwellings or a tiny house community will be more complex to prepare and assess than that for a single dwelling for example.
Building policy is about ensuring the health and safety of people interacting with buildings. It also includes performance requirements, such as for energy efficiency and water consumption. The overarching compliance instrument is the Building Code of Australia (BCA) which is part of the National Construction Code (NCC). This is developed and maintained by the Australian Building Codes Board (ABCB) which is Federally funded. Each State and Territory has the right to add “State Variations” to the BCA. State and Territory Building Acts and Regulations also apply, but these are mainly administrative. The BCA is the primary construction code.
As noted above, tiny houses built on a registered trailer base are typically not “buildings” for the purposes of the BCA or State and Territory Building Acts. This can have positive and negative implications.
A tiny house connected to infrastructure and/or permanent foundations, or added to with a deck, or even steps constructed on site, will likely be deemed to be a building, or to contain “assessable building work” by local government compliance officers. All such work must be assessed for compliance with relevant codes and standards, most commonly this means compliance with the BCA.
To connect to infrastructure, particularly a municipal sewer, a building permit is often a prerequisite.
The law currently only requires the trailer to comply with Australian Standards and Codes. Anything added onto that trailer (the load) just needs to remain with the weight and dimensional requirements of VSB1, nothing more.
If you are trying to get a completed THOW assessed as a building, unless there has been a paper-trail with certificates issued by suitably qualified specialists covering the construction from the outset, it can be extremely difficult to demonstrate compliance with the BCA.
Building Code compliance is assessed by a Building Certifier. Some local government areas have building certifiers on staff, but there is also the (more common) possibility of using a Private Building Certifier that you appoint to assess your building permit application.
If you are thinking to DIY your build, then it will be essential to complete an Owner Builder’s course to understand what needs to be done to generate the paper trail required for building approval.
Also do some tiny house specific training such as offered by ATHA members and long-standing tiny house advocate, Fred’s Tiny Houses, or the like. You will not learn about building onto a trailer in a conventional owner-builder course!
Our March 2024 newsletter included discussion about what is involved in obtaining building approval and some of the challenges facing tiny houses on wheels.

A proposal for multiple dwellings or a tiny house community will be more complex to prepare and assess than that for a single dwelling for example.
Some Council websites have a self-help tool to determine the level of assessment required, but for others it may be necessary to seek advice from an independent Town Planning Consultant to fully appraise the opportunities and constraints of a particular block of land and the approval pathway required, particularly if you intend to have more than a single dwelling unit on the property.
Tip: “Development” does not apply to vehicles. If a tiny house on wheels is registered (or capable of being registered) as a vehicle, it is not subject to development assessment or policies. Parking vehicles on private land is not development, but most local government areas will have Local Laws or something similar restricting the use of a vehicle such as a caravan for accommodation purposes.

There are currently no recognised construction standards for THOW in Australia. Some THOW are built as DIY projects by enthusiastic amateurs with little or no qualifications. There are also Australian licensed builders with full trade qualifications constructing THOW to NCC performance equivalence on purpose-built trailers engineered to carry the load of such construction. The law currently only requires the trailer to comply with Australian Standards and Codes. Anything added onto that trailer (the load) just needs to remain with the weight and dimensional requirements of VSB1, nothing more.

Building Code compliance is assessed by a Building Certifier. Some local government areas have building certifiers on staff, but there is also the (more common) possibility of using a Private Building Certifier that you appoint to assess your building permit application.
Private building certifiers are independent consultants, but they are bound by law to adhere to a rigorous process of compliance assessment. Once a certifier grants approval, they will also lodge a record of that with the local authority. The information that a building certifier will require is highly technical and as such can be very difficult for an unqualified person to understand, source or supply. The easiest way is to have your builder manage, and take responsibility for, the process for you.

A tiny house may be deemed to be a dwelling unit for planning purposes, and as such, it may require a formal application to Council to demonstrate how the proposed use complies with relevant planning policies and codes.
A tiny house may be deemed to be a dwelling unit for planning purposes, and as such, it may require a formal application to Council to demonstrate how the proposed use complies with relevant planning policies and codes. Planning approval may be granted, but it will always be subject to conditions, which usually include the requirement for further approvals, such as a building permit and/or services connection permit. Unless the tiny house can satisfy all planning approval conditions, that approval cannot be exercised.
Obtaining building approval for a tiny house on wheels needs careful project management to ensure that all the compliance evidence required by, and to the satisfaction of, the Building Certifier, can be supplied.
A tiny house may pass as a caravan, in which case it is not subject to planning or building assessment, but Local Laws and the like will still apply. Tiny house dwellers are sometimes under the impression that because their THOW is a caravan “no approvals are required.” Whilst this may be technically correct, it does not always mean that it is possible to live permanently in your THOW on your own land or somebody else’s, or to connect it to a services infrastructure.
NSW currently has fairly liberal rules about living in a caravan, but these are under review and it seems likely that the outcome will have greater restrictions on THOWs. The official wording is “to provide clarity” but that doesn’t necessarily mean making it easier. For more information and to make a submission to the NSW Government planning framework review for caravan parks, camping grounds, manufactured home estates and moveable dwellings see: https://www.planning.nsw.gov.au/policy-and-legislation/housing/housing-sepp/caravan-parks-manufactured-home-estates-and-moveable-dwellings
Some caravan parks will accept THOW on a long-term basis, like a park cabin or permanent on-site caravan. This is currently the most certain opportunity for living permanently in a THOW, but not everyone wants to live in such a situation. Tiny House Villages or Communities are potentially a variation on the concept of a caravan park.
Property in a rural area may have the option to install worker’s accommodation or similar additional dwelling units “as of right” without further assessment. Traditionally this was intended for seasonal workers, or multi-generational families. More recently we have seen the advent of farm-stay and/or bed and breakfast style accommodation as a means for farm owners to diversify their income stream. Depending upon the intended use and local government policies, multiple dwelling units for un-related people on a working farm may be a possibility.
There is also “Rural Residential” land which has the character of a hobby farm or an acreage block that is typically too small to generate a primary production income but is substantially larger than a suburban house block. This category of land zoning is typically not granted the same flexibility with accommodation options as a full working farm. Please be aware it is this type of land zoning upon which some tiny home eviction situations have been reported.
Alternative pathways typically include some risk of being forced to move on, but in many cases, they are currently the only feasible option for people unable to obtain a building permit for their THOW.

We hope that you have found this information useful. There is still a long way to go before living in a moveable tiny house is an option for all who choose it. ATHA continues to take the call to government, but we are just a handful of volunteers and Australia is a big country, so please, help us to help you by making personal contact with your local elected representative to ensure that they know tiny houses are an option that a great many people are interested in.
Point out the Shire of Esperance in WA as the first local government area in Australia to welcome tiny house living. Ravensthorpe and Capel Shires, also in WA, have since followed suit and others are actively exploring options. The Surf Coast Shire in Victoria is currently conducting a tiny house trial. Shellharbour in NSW recently announced plans for a trial. Find out more good news on our website: https://tinyhouse.org.au/atha-news/
