Tiny House Rules and Regulations in Tasmania

Updated October 2026 | AHA Research Team

In Tasmania, you can build a fixed backyard tiny home of up to 60 m² without a planning permit in the main residential zones, as long as it meets the planning rules. A proposal to raise that limit to 90 m² is still being assessed.

Living in a tiny home on wheels is different. Tasmania’s building regulator treats it like a caravan, not a building. But living in it on residential land still needs council planning approval, and it can’t be connected directly to water or sewer.

Before you start, check with your council about any planning codes that affect your site, such as bushfire or landslip. For building and plumbing rules, see Building Standards Tasmania.

Quick Answers

Only with council approval. Living in a tiny home on wheels counts as a residential use, so it is assessed under the planning scheme like any other home. The rules depend on your zone.

Only with council approval. On residential land, this applies whoever lives in it, including family. Approval is under the planning scheme or your council’s caravan by-laws.

We found no state rule that allows any stay without approval. Some councils have by-laws for the temporary use of caravans, so check with yours.

Not directly. Fixed plumbing can’t be connected to a tiny home on wheels. Instead, it can be parked next to plumbed facilities, such as an approved dump point connected to the sewer. These facilities need council approval before use.

Yes, in the main residential zones, if it is 60 m² or less and shares the main house’s driveway, parking, connections and meters. It must also meet your zone’s rules and any planning codes.

Usually not a building permit. A fixed tiny home is normally notifiable work, which needs a Certificate of Likely Compliance from a building surveyor. It becomes permit work, needing a council building permit, if it needs a planning permit or you build it as an owner builder. A road registrable tiny home on wheels is not a class of building under the NCC.

Tiny house on wheels (THOW)

Quick answer: In Tasmania, you need council approval to live in a tiny home on wheels on residential land, whoever lives in it. It must stay free-standing. If it is connected to water or wastewater, or joined to a deck or awning, it would normally be treated as a permanent structure.

Is it a caravan or a building?

Tasmania’s building regulator, Building Standards Tasmania (formerly part of Consumer, Building and Occupational Services, or CBOS), says in its regulatory note on tiny houses that a tiny home on wheels is a road registrable vehicle (one that can be registered for public roads and towed behind a car), like a caravan or camping trailer. It also says a road registrable vehicle is not a class of building under the National Construction Code (NCC, the national rules for building design and construction).

Being road registrable does not take a tiny home outside planning law. The State Planning Office says a tiny house used as a permanent home is a residential use, whatever its size, and is assessed under the Tasmanian Planning Scheme like any other house.

A tiny home on wheels only counts as road registrable while it stays free-standing. The regulator says it is no longer road registrable once it is connected to the ground by any building or plumbing work. The State Planning Office says a tiny house connected to water or wastewater, or joined to a deck or awning, would normally be treated as a permanent structure.

If your tiny home is not road registrable, the regulator says you need a licensed building designer or building surveyor to work out its building class under the NCC. If it is classed as a house (Class 1a), the normal building and plumbing approvals apply.

Planning approval to live in a tiny home on wheels is not building approval. The regulator says one does not imply the other.

When you don’t need approval to live in it

We found no state rule that lets someone live in a tiny home on wheels, even for a short time, without council approval. The regulator says living in one on residential land needs planning approval or approval under a council’s caravan by-laws. We also found no state guidance on storing an empty tiny home on wheels, so check with your council.

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 on residential land. The regulator says anyone who plans to live in a tiny home on wheels on land zoned for residential use needs council planning approval. This comes either under the planning scheme or under a council’s by-laws for caravans.

Living on a vacant block or in other zones. A tiny home used as a permanent home is assessed as a residential use under the Tasmanian Planning Scheme. The rules depend on your zone. Planning codes for things like parking, access, bushfire, flooding and landslip may also apply.

Council caravan by-laws. Some councils have by-laws for the temporary use of caravans and other mobile structures. These can apply even when you don’t need a planning permit, so check your council’s by-laws as well as the planning rules.

Water and wastewater. The regulator says fixed plumbing must not be connected to a tiny home on wheels. Instead, it can be parked next to plumbed facilities. These can be a Class 10 structure (a non-habitable building, such as a shed) with approved plumbing, a prefabricated bathroom pod with WaterMark-certified fixtures, or an approved dump point (a place to empty toilet cassettes and sink and shower water). A dump point can connect to the TasWater sewer, or to a sealed tank that an accredited contractor pumps out regularly. The tiny home’s fixtures can’t connect to a dump point directly. They must drain over it. All of these options need full council approval before use, and all plumbing must be done by a licensed plumber.

Short-stay accommodation. The State Planning Office says there are separate planning rules if you want to offer a tiny home for short-stay accommodation. Check with your council before you list it.

Towing and registration

To tow a tiny home on wheels on public roads in Tasmania, it must be registered as a trailer. You register it through Service Tasmania after it passes an inspection at an approved inspection station. A trailer is a light vehicle unless its Aggregate Trailer Mass (ATM, its maximum loaded weight) is more than 4.5 tonnes. Above that, it is a heavy vehicle under the Heavy Vehicle National Law. Under the Vehicle and Traffic (Vehicle Operations) Regulations 2024, a light vehicle can be up to 2.5 metres wide and 4.3 metres high, and the car and trailer together can be up to 19 metres long. Our buying guide covers these limits, plus electric brakes, driver licences and registration, in detail.

Wider than 2.5 metres? Using a light vehicle wider than 2.5 metres on a public road is an offence. The fine is up to 20 penalty units for a first offence and up to 40 for a repeat offence. The regulations let you apply to the Transport Commission for a permit, which can come with conditions. We found no general exemption for tiny homes. If you’re planning a home wider than 2.5 metres, talk to Transport Services (Department of State Growth) and your builder about how it will be moved before you commit.

Tiny house on foundations

A tiny home that isn’t road registrable is treated like any other building. The regulator says a building surveyor or building designer works out its class under the NCC, and if it is a house (Class 1a), the normal building and plumbing approvals apply. A fixed tiny home can be a backyard home alongside a main house, or your main house itself.

Backyard tiny homes (secondary residences)

Under the Tasmanian Planning Scheme, a fixed backyard tiny home is usually a secondary residence (often called a granny flat). This is a small, self-contained home that goes with the main house on the same lot. The planning scheme treats the main house and its secondary residence together as a single dwelling. A secondary residence can be attached to the main house, inside it, or a separate building.

The planning scheme’s definition doesn’t limit who can live in it. The State Planning Office says secondary residences can be used for ageing in place, multi-generational living and smaller household rentals.

The No Permit Required pathway

A secondary residence is No Permit Required (you don’t need a planning permit from council) in the General Residential, Inner Residential, Low Density Residential, Rural Living and Village zones, if it meets all the relevant planning rules. You still have to meet those rules, even though no permit is issued.

  • Size: a gross floor area of 60 m² or less. In Tasmania, this is measured from the outside of the walls.
  • One main house: it must go with a single main house on the same lot.
  • Shared access and services: it must share the driveway and parking with the main house, as well as the water, sewerage, gas, electricity and telecommunications connections and meters. It can have its own laundry or share one with the main house.
  • Zone rules: it must meet your zone’s rules for building height, setbacks (distance from boundaries) and site coverage. The General Residential and Inner Residential zones also have rules for private open space and privacy.
  • Planning codes: codes in the planning scheme can add extra rules, such as for parking and access, natural and heritage values, and hazards like bushfire, flooding and landslip.
  • Other zones: in all other zones, you’ll need a planning permit, or a secondary residence may not be allowed at all.

You can ask your council to confirm that your plans are No Permit Required. You can also get a Certificate of No Planning Approval Required from a licensed planning consultant.

If your home doesn’t meet these rules

A self-contained home that doesn’t meet the secondary residence rules is generally treated as a multiple dwelling (two or more separate homes on the same site). Multiple dwellings need a planning permit. In the General Residential, Inner Residential and Village zones they are Permitted, which means council must issue a permit, although it can add conditions. In the Low Density Residential zone they are Discretionary, which means council can say yes or no, the public can comment, and others can appeal. They are not allowed in the Rural Living zone.

The size limit may increase

Tasmania has proposed raising the limit to 90 m². Until that is approved, the 60 m² limit applies. See “What’s changing in Tasmania” below.

Approvals you still need

  • Building approval: In Tasmania, a detached house or unit is usually notifiable work (medium-risk building work). You apply to a licensed building surveyor, who checks the design and issues a Certificate of Likely Compliance. Council is notified that the work is taking place, but doesn’t need to give approval. If the home needs a planning permit, or you’re building it yourself as an owner builder, it becomes permit work. You then also need a building permit from council. Most work in hazardous areas is also permit work.
  • Occupancy permit: you need an occupancy permit before anyone moves in.
  • Plumbing: all plumbing work must be done by a licensed plumber. Drinking water and wastewater are public health matters, so every fixed connection must meet the Building Act 2016 and the NCC. Plumbing is approved by your council’s permit authority. Most work needs a Certificate of Likely Compliance. Higher-risk work, such as an on-site wastewater system (for example, a septic tank), needs a plumbing permit.

Building standards

Building code: The Building Amendment Act 2026 took effect on 5 June 2026. It reinstated NCC 2022 as Tasmania’s building code until 1 May 2027, when NCC 2025 will be adopted. NCC 2025 had applied briefly from 1 May 2026. Some projects that were already underway may fall under transitional rules, so check with your building surveyor.

Energy efficiency: In Tasmania, the NCC 2022 energy efficiency rules for houses are replaced with the older 2019 rules. This means the 7-star NatHERS (Nationwide House Energy Rating Scheme) requirement used in most other states doesn’t apply. The Tasmanian Government has said new homes need a minimum 6-star rating.

Ceiling heights: Under the NCC’s standard rules, habitable rooms such as bedrooms and living areas need a ceiling height of at least 2.4 metres. Kitchens and corridors need at least 2.1 metres. An attic or loft room needs at least 2.2 metres over at least two-thirds of its floor area.

Fire separation: Under the NCC, an external wall of a house that is less than 1.8 metres from another building on the same lot, or less than 900 mm from a side or rear boundary, must meet fire separation rules. One way to meet them is a fire-resistance level (FRL) of 60/60/60. Some buildings are exempt from the 1.8-metre rule, such as a garage or shed that goes with the house. Your building surveyor will confirm what applies.

Bushfire: if your site is in a bushfire-prone area, the building work must meet Tasmania’s bushfire building rules. You’ll need a bushfire hazard management plan from a bushfire hazard practitioner accredited by the Tasmania Fire Service. The plan sets your Bushfire Attack Level (BAL, worked out using Australian Standard AS 3959), the construction requirements, and a hazard management area (a cleared, defendable space around the home).

A tiny home as your main house

A fixed tiny home can be the only home on your block. The State Planning Office says a tiny house used as a permanent home is assessed like any other house, whatever its size. In planning terms it is a single dwelling. That means a self-contained home with a kitchen, a bath or shower, laundry facilities, a toilet and a sink.

A single dwelling is No Permit Required in the General Residential, Inner Residential, Low Density Residential, Rural Living and Village zones, if it meets the zone rules for building height, setbacks and site coverage. Planning codes, such as for bushfire or heritage, may also apply. Other zones have different rules. The same building approvals and building standards described above apply.

Before you buy or build, also check your property title for covenants (private restrictions registered on the title). These can limit what you build, even when the planning rules allow it.

What’s changing in Tasmania

Updated October 2026. This is moving quickly, so check back.

Bigger backyard tiny homes. Draft Amendment 01-2026 proposes raising the size limit for secondary residences from 60 m² to 90 m². It would also clarify how the rules work on blocks without town water and sewer, and confirm that no extra parking space is needed. The amendment was publicly exhibited from 10 June to 22 July 2026, and the Tasmanian Planning Commission held hearings in September 2026. As of October 2026, no decision has been made. The Commission will report to the Minister, who makes the final decision.

A new building code in 2027. NCC 2025 started in Tasmania on 1 May 2026, but the Building Amendment Act 2026 reinstated NCC 2022 from 5 June 2026. According to Building Standards Tasmania, NCC 2025 will be adopted from 1 May 2027.

Tiny homes on wheels. A Legislative Council e-petition, open until 6 November 2026, asks the government to create a clear approval pathway for living long term in a tiny home on wheels. We found no government proposal for one yet.

What this means for you right now: these are proposals, not law. Until they change, the 60 m² limit and the rules above still apply.

Tasmania councils to watch

Huon Valley: in September 2025, the council released a “Tiny house on wheels: Council’s role” fact sheet. It says the council helps applicants seek planning approval for tiny homes as a residential use, and takes an education-first approach to compliance. It also says the council is lobbying the Tasmanian Government, including through the Local Government Association of Tasmania, for planning and building law reform. The fact sheet is clear that councils can’t make by-laws that override state law, so it doesn’t create a local pathway of its own.

FAQs

Tiny home on wheels: only with council approval. Living in a tiny home on wheels on residential land needs council planning approval, whoever lives in it, so the same applies to a tenant. We found no state rule written specifically for renting one out, so check with your council first.

Fixed backyard tiny home: yes. The State Planning Office says secondary residences can be used for smaller household rentals. Tenancies are covered by the Residential Tenancy Act 1997. Under that Act, any bond must be lodged with the Rental Deposit Authority, and the home must meet minimum standards for rental premises, including for electricity and heating.

Tiny home on wheels: check with your council first. Tasmania’s planning exemption for short stays applies to short-stay accommodation within a dwelling that is your main home. We found no state guidance on whether it covers a tiny home on wheels.

Fixed backyard tiny home: you don’t need a planning permit if the property is your main home and you either let it only while you’re away or temporarily absent, or you live there while guests use no more than 4 bedrooms. This is called the home-sharing exemption. Otherwise, you need a planning permit from council. Check with your council that the exemption covers your setup.

In the main residential zones, the Short Stay Accommodation Act 2019 requires you to tell booking platforms like Airbnb your planning permit status before you start.

Council rates: each council sets its own rates. Ask your council how adding a tiny home would affect yours.

Land tax: land classified as your principal residence (main home) is not subject to land tax. The State Revenue Office says that if you rent out any part of your property, land tax may apply to the rented portion. Contact the State Revenue Office if you plan to rent out a tiny home.

Tiny home on wheels: fixed plumbing can’t be connected to a tiny home on wheels. Instead, it can be parked next to plumbed facilities, such as an approved dump point, which need council approval. The regulator says waterless composting toilets are not permitted in a caravan or trailer-based structure. An on-site wastewater system, such as a septic tank, can only be installed with a building recognised under the NCC.

Fixed backyard tiny home: you need a plumbing permit for any on-site wastewater system, such as a septic tank, and the work must be done by a licensed plumber. Waterless composting toilet systems must be accredited for use in Tasmania. You can find the list on the Building Standards Tasmania website. Water from sinks, showers and laundries (greywater) still has to be treated through an approved system.

Common myth:

Being off-grid doesn’t get around the rules. Storing rainwater for drinking counts as plumbing work, and on-site wastewater systems need a plumbing permit. Check with your council before you install anything

Tiny home on wheels: it can be sold like a caravan or trailer, so the land isn’t involved. If it’s registered, the registration needs to be transferred to the buyer.

Fixed backyard tiny home: not as a secondary residence. The planning scheme treats a secondary residence as part of the single dwelling on the same lot, sharing its access, parking and services. Separate homes with their own owners are treated as multiple dwellings, which have different planning rules. Talk to your council before planning to sell separately.
