Tiny Home Regulations in South Australia (Revised Aug 2026)

Tiny homes are changing the way people live in South Australia. They offer an affordable and sustainable way to find a home without a massive price tag. Understanding the regulations is the best way to make sure your project goes smoothly.

This guide gives you a clear overview of the rules in South Australia. We’ll cover tiny homes on wheels and those built on foundations. We’ll keep this post updated as the laws evolve.

Note: While this guide makes understanding regulations very easy, it should not be considered legal advice. Contact your local council to confirm requirements before proceeding.

Regulations for tiny homes on wheels in South Australia

Tiny homes on wheels (often called THOWs for short) are a popular choice because they give you the freedom to move your home if your circumstances change. In South Australia, the rules for these homes are quite different from the rules for homes built on permanent foundations.

Legal classification

In the eyes of the law, tiny homes on wheels are generally treated as caravans or moveable dwellings — any type of home that’s designed to be moved, like a trailer, a van, or a tent.

This classification is important because it changes which rules you have to follow. Instead of following the standard building codes for a permanent house, your tiny home must follow road and vehicle rules while it’s being moved, and specific council bylaws (local rules made by your council) while it’s parked.

Registration and road requirements

If you want to tow your tiny home on South Australian roads, it must be registered and roadworthy. This is managed by the Department for Infrastructure and Transport (DIT) — the government body that looks after the state’s roads and vehicles.

To be road-legal without needing a special oversized load permit, your tiny home must follow a set of national standards called VSB1 (Vehicle Standards Bulletin 1). This is basically the national “rulebook” for building trailers.

Your tiny home must fit within these dimensions:

• Weight: Up to 4.5 tonnes (4,500 kg) ATM.
• Width: No more than 2.5 meters.
• Height: No more than 4.3 meters.
• Length: No more than 12.5 meters for the trailer itself (including the drawbar), or 19.0 meters for the whole “combination” (your car and the tiny home together).

For licensing and towing capacity, the critical figure is ATM (Aggregate Trailer Mass). This is the total weight of your trailer including the portion supported by the hitch or jockey wheel. It’s the maximum your tiny home can weigh when it’s not hitched to a vehicle.

Towing and licensing in South Australia

Towing a heavy tiny home requires a bit more than just a tow bar. You need to make sure both your vehicle and your license are up to the task.

Licensing

You can generally tow a tiny home with a standard Class C (Car) license. The most important thing to know is that your license class is determined by the GVM of your towing vehicle, not the weight of the trailer.

• GVM (Gross Vehicle Mass is the maximum weight your car or truck is allowed to weigh when it’s fully loaded. This includes the car itself, passengers, fuel, and the weight pushing down from the trailer’s hitch.
• As long as your towing vehicle’s GVM is 4.5 tonnes or less, your Class C license is all you need.
• If you’re using a much larger truck (with a GVM over 4.5 tonnes) to tow your home, you’ll likely need a Light Rigid (LR) or Medium Rigid (MR) license.

Braking standards

There are strict rules about the brakes your tiny home must have:

• Brakes are required if the trailer’s GTM is more than 750 kg. GTM (Gross Trailer Mass): This is the weight transmitted to the ground through the trailer’s axles when it’s hitched to your car.
• A breakaway system is required if the trailer weighs more than 2 tonnes. A breakaway system is a safety device that automatically slams on the trailer’s brakes if it ever accidentally unhooks from your car while you’re driving.

Always double-check with the Department for Infrastructure and Transport or a local mechanic to ensure your setup is safe and legal.

Here’s a diagram to help you understand the different towing terms:

When you need approval for tiny homes on wheels

Even though a tiny home on wheels’s technically a vehicle, you still need to follow planning rules if you intend to live in it. The Planning, Development and Infrastructure Act 2016 (PDI Act) sets out the scenarios where you must get formal permission before you can settle in.

Approval scenario 1: Using a tiny home as your only home on vacant land

If you buy a block of land and want to live in your tiny home on wheels without building a main house first, the law sees this as “Development.”

This means you can’t just park your home on a vacant lot and start living there. You’ll need to submit a full Development Application (DA) via the PlanSA portal to request permission to use your land in a specific way.

The council will look at three main things before they’ll say yes:

• Zoning: Does the local “rulebook” allow people to live on that specific piece of land?
• Wastewater: How will you handle sewage? You’ll need an approved on-site wastewater system (a system on your property, like a septic tank, that treats waste because you aren’t connected to town pipes).
• Bushfire safety: If your land is in a high-risk area, you’ll need to show that your home is safe and has enough water nearby for fire trucks.

Under the Planning, Development and Infrastructure Act 2016, “Development” isn’t just about pouring concrete. It includes Change in Land Use, such as taking a vacant piece of land and using it for residential purposes

Important Note: Under the PDI Act 2016, simply parking an unfixed THOW is not development. However, the moment it is occupied as a permanent, independent primary residence, it triggers a Change in Land Use requiring Planning Approval. If you connect it to rigid, permanent onsite plumbing rather than flexible caravan-style hoses, councils will argue the structure has lost its mobile status, reclassifying it as a permanent building that must undergo full Building Consent against the National Construction Code.

Approval scenario 2: Stays that exceed temporary limits

In South Australia, local councils often treat a tiny home on wheels like a caravan. Most councils have “bylaws” (local rules) that allow you to stay in a caravan for a short time, but there’s usually a limit.

While every council is slightly different, the limit’s often 30 to 60 days per year. If you plan to live in your tiny home for longer than that, it isn’t considered “temporary” anymore.

Once you cross that time limit, the council may require you to prove your home’s connected to a safe, approved wastewater system to protect the environment and your health.

If you want to stay for several months or live there permanently, you’ll typically need to apply for a permit or a DA via the PlanSA portal 

Approval scenario 3: multiple tiny homes for business use

If you want to set up more than one tiny home on your property — for example, to run a “tiny home hotel” or a holiday rental business — this is a big change in how the land is being used.

You’ll need to apply to have your land “reclassified” (officially changed in the government records) for commercial or tourist use. This process involves a more detailed application to make sure the extra traffic and waste don’t bother your neighbors or the local environment.

Contact your local council’s planning department to ask about their specific “moveable dwelling” bylaws. They’re usually very happy to explain the rules so you don’t run into trouble later.

When you don’t need approval for tiny homes on wheels

There are certain situations where you won’t need to go through the full Development Application (DA) process to use a tiny home on wheels. These exemptions’re designed to give you flexibility for short-term visits or emergency situations.

Exception scenario 1: Short-term stays for guests

If you have a friend or family member who wants to stay in your tiny home on wheels in your backyard for a short visit, you generally won’t need council approval.

For the stay to be exempt, it must be “ancillary” (this is a legal word that means the tiny home’s use is secondary or extra to the main house).

This means:

• No permanent fixing: The tiny home must stay on its wheels and not be permanently attached to the ground or the house.
• Shared facilities: Your guest should generally use the kitchen or laundry in the main house rather than living completely independently.
• Time limits: While there isn’t a single statewide limit for guests, most councils consider “short-term” to be anything from a few days to a few weeks.

If the visit’s only for a weekend or a short holiday, there’s usually no need for paperwork. However, if your guest stays for more than a month, it’s a good idea to check your local council’s bylaws.

Exception scenario 2: Disaster recovery

South Australia has special rules to help people who’ve lost their homes due to natural disasters, like a major bushfire or flood.

Under the Planning, Development and Infrastructure (General) Regulations, you can live in a caravan or a tiny home on wheels on your property for up to 2 years (24 months) without a DA if you’ve been displaced by a disaster.

• Rebuilding period: This exemption’s meant to give you a safe place to stay while you wait for your permanent home to be repaired or rebuilt.
• No red tape: You don’t have to wait for planning permission to move onto your land in this emergency situation.
• Safety first: Even though you don’t need a DA, you still need to ensure the setup’s safe. It’s especially important to have a safe way to handle wastewater so you haven’t any health risks on your property.

If you’re planning to host a guest for more than a couple of weeks, it’s always worth a quick phone call to your council’s planning department.

Just tell them you’re hosting a “moveable dwelling” for a short time and ask if they’ve any specific local time limits. It’s much better to know the local rules early so there isn’t any confusion later.

Regulations for tiny homes on foundations in South Australia

If you’re building a tiny home that’s fixed to the ground with permanent footings or a concrete slab, the law sees it as a permanent building. In South Australia, these’re officially called Ancillary Accommodation (you might know them better as “granny flats” or “secondary dwellings”).

Using a tiny home on foundations as a primary dwelling in SA

You can build a tiny home as your main residence on a block of land where there’s no other house. In this case, it’s treated exactly like a “normal” full-sized home.

• Zoning: This is generally permitted in residential zones (the areas of a town or city where houses’re allowed).
• The Building Code: Your home must meet the NCC (National Construction Code) Class 1a standards. A Class 1a building is a single home that’s lived in permanently. Meeting this code ensures your home’s structurally safe, fire-resistant, and properly insulated.
• Off-grid systems: If your land’s in a rural area without town pipes, you can use off-grid systems. However, you’ll need approval from SA Health and sometimes the EPA (Environment Protection Authority) for your wastewater system. This ensures that your sewage treatment (like a septic tank) doesn’t pollute the local environment or water supply.

A tiny home on foundations becomes a Class 1a Building under the National Construction Code (NCC).

Using a tiny home on foundations as a secondary dwelling in SA

Most tiny homes on foundations’re built as a second home in the backyard of an existing house. Between 2024 and 2026, the South Australian government introduced major reforms to make this process much easier.

• Increased floor area: You can now build a tiny home up to 70m² in size. Previously, the limit was only 60m².
• Fully self-contained: Your tiny home is now allowed to have its own kitchen, bathroom, and laundry — you no longer need to share these facilities with the main house.
• Bedroom limit: To be classified as “ancillary” (extra to the main house), your tiny home’s restricted to a maximum of 2 bedrooms.
• Open tenancy: You can now rent your tiny home in the backyard to anyone. 

Critical compliance requirements for renting your tiny Home on foundations in South Australia

Even though South Australian law now permits renting a secondary dwelling to anyone, the structure must be legally habitable to be used as a long-term residence. For tiny homes on foundations, compliance is governed by specific building and tenancy regulations:

1. Building Classification (Class 1a) 

A tiny home on foundations is legally classified as a permanent building. To be rented out as a residence, it must meet National Construction Code (NCC) Class 1a standards. This ensures the structure is built to the same habitable safety levels as a standard house, covering:

• Structural Integrity: Load-bearing capacity of the slab or footings.
• Fire Safety: Mandatory smoke alarms and fire-resistant materials.
• Energy Efficiency: Compliance with minimum star ratings for insulation and glazing.
• Moisture Management: Proper waterproofing in “wet areas” (kitchen, bathroom, and laundry).

2. Development Approval (PlanSA)

Under the Planning, Development and Infrastructure Act 2016, you must obtain full development approval via the PlanSA portal. 

This consists of two mandatory parts:

• Planning Consent: Assessment against the Planning and Design Code to ensure the home meets boundary setbacks, site coverage limits, and does not negatively impact neighbor amenity.
• Building Consent: Technical verification by a building certifier (Council or private) that the design and construction meet the NCC Class 1a requirements.

3. Tenancy Laws and Form A1

Once you enter a rental agreement with a non-family member, you are a landlord governed by the Residential Tenancies Act 1995. Key 2026 requirements include:

• Mandatory Form A1: Since January 1, 2026, all landlords must use the prescribed Form A1 (Standard Rental Application) to consider prospective tenants. This form limits the personal information you can request from applicants.
• Bond Lodgment: Any rental bond collected must be lodged with Consumer and Business Services (CBS) within the required statutory timeframe.
• Utility Metering: Unless the tiny home is separately metered, you must have a clear, written agreement regarding how utility costs (water, electricity) are apportioned between the primary and secondary dwelling.

Navigating the tiny home approval process via PlanSA

Getting your tiny home approved in South Australia is now managed through a single, statewide system. You no longer need to navigate different paperwork for every council; instead, you will use the PlanSA Portal, the state’s centralized online system for all planning and building applications.

Lodging your application

All development applications must be submitted through the PlanSA website. You will need to create an account, upload your architectural and engineering plans, and pay the required fees directly through the portal.

You can track your application’s progress in real-time, receiving notifications as it moves from lodgment to final approval.

Finding the right approval pathway

There are two primary ways your application can be assessed under the Planning and Design Code. Choosing the right one can significantly impact your timeline and costs.

• Deemed-to-Satisfy (DTS): This is the “fast-track” approval pathway. If your tiny home meets all the strict pre-set criteria in the Code — such as being no larger than 70m², sitting behind the main house building line, and strictly sharing its utility connections (water, power, and sewer) with the primary home — it must be granted planning consent. Keep in mind that opting for a separate SA Water meter will instantly disqualify you from this fast track.
• Performance Assessed: If your design deviates from the standard rules (e.g., you decide to install separate utility meters, or build closer to boundaries than standard envelopes allow), it will be assessed on its individual merits. This process requires a detailed review by a planning officer and generally takes longer.

Adhering to the “Deemed-to-Satisfy” criteria, and keeping your services shared, is the most efficient and cost-effective way to secure rapid approval.

Wastewater approval

Even after securing planning and building consent, there is a mandatory final step: Wastewater Approval. This is granted by your local council’s health department and covers the management of sewage and “greywater.”

• The requirement: You must apply for a wastewater permit if you are installing a new onsite septic system or connecting to an existing network.
• The cost: You should budget between $400 and $650 for the application and the health officer’s mandatory site inspections.
• The rule: This approval must be obtained before any plumbing work begins on-site.

Budgeting for utility and augmentation costs

Connecting a tiny home to water and power can be one of the project’s most significant expenses. When building a permanent tiny home on foundations, you must account for SA Water charges.

• Augmentation charges: Because you are adding a new dwelling unit to the property, you will likely be charged an “Infill Augmentation Fee.” This helps fund the local water and sewer network. In 2026, these fees are approximately $2,560 for water and $2,560 for sewer (totaling roughly $5,120).
• Separate water meters: If you intend to rent out the tiny home and bill the tenant for their specific usage, you will need a separate water meter. A new 20mm metered connection in 2026 can cost $4,000+ depending on the complexity of the installation.

While “Ancillary Accommodation” is the term used for planning, SA Water treats these as “Secondary Dwelling Units” for billing and augmentation purposes. Be sure to use the correct terminology when dealing with each department to avoid delays.

How do tiny home regulations in South Australia compare to other states?

Comparing South Australia to the rest of the country helps you see just how flexible the local rules are. Here’s how the other states’re managing tiny homes and secondary dwellings in 2026:

Victoria

• Planning Exemption and Size Caps: Under the Small Second Dwelling provisions, a permanent tiny home is completely exempt from a council planning permit if it sits on a lot of 300 square metres or larger and its gross floor area is 60 square metres or less. Properties smaller than 300 square metres must undergo the full planning permit process.
• Siting and Access Requirements: Building regulations mandate positioning a small second dwelling behind the front wall line of the primary residence. The design must comply with standard setbacks, open space requirements, and daylight rules, while providing a clear, 1-metre-wide all-weather pedestrian path from the street.
• Gas Connection Ban: To qualify for a planning exemption, tiny homes are strictly barred from connecting to reticulated natural gas. In line with the state’s Gas Substitution Roadmap, these builds must rely entirely on all-electric alternatives like solar panels or electric heat pumps.
• South Australia Contrast: Victoria caps its exempt tiny homes at 60 square metres and enforces a 300-square-metre minimum lot size. In contrast, South Australia allows footprints up to 70 square metres and features a digital PlanSA fast-track stream that requires sharing utility connections with the primary house.

Western Australia

• Size Caps and Lot Deregulation: The R-Codes ‘Part B’ amendments eliminated minimum lot size constraints for ancillary dwellings. Homeowners can add a fixed tiny home of up to 70 square metres on almost any residential block without a long development application, provided the design complies with basic setbacks.
• 24-Month Moveable Dwelling Permits: Local councils can approve full-time habitation in a tiny home on wheels (THOW) for up to 24 months at a time. Owners can apply for consecutive 24-month extensions as long as they meet state health regulations for on-site sewage and greywater management.
• 5-Night Casual Stay Exemption: Caravan and camping regulations grant a permit-free allowance for mobile tiny homes. A person can stay in a THOW on land they own, or where they have permission, for up to 5 nights within any 28-day window without notifying the council.
• South Australia Contrast: Both states offer a generous 70-square-metre limit for fixed ancillary dwellings. However, Western Australia grants much more freedom for mobile tiny homes through its 5-night exemption and 24-month permits, whereas SA’s mobile regulations remain heavily fragmented by council area and often cap stays at 30 to 60 days per year.

New South Wales

• 450m² Complying Development Threshold: Under the Housing SEPP 2021, a fixed tiny home can bypass the full council development application process. It can secure approval within 20 days via a private certifier if the residential lot is at least 450 square metres and the dwelling stays under 60 square metres.
• 2-Day Casual Stay Limit: Local government regulations allow using a tiny home on wheels for short-term visitor accommodation without council approval. However, stays are bound by a strict curfew of no more than 2 consecutive days per visit and a cumulative cap of 60 days per year.
• Light Vehicle Road Rules: A THOW under 4.5 tonnes and up to 3.5 metres wide can be towed on state roads without an individual oversize permit. It must display prominent “Oversize” warning signs, use an amber flashing light if wider than 3.0 metres, and avoid weekday urban peak-hour curfews.
• South Australia Contrast: NSW enforces a strict 60-square-metre ceiling and a high 450-square-metre lot minimum for fast-track approvals. South Australia offers more freedom by permitting spaces up to 70 square metres via the PlanSA fast-track stream, matching NSW’s open tenancy access but applying distinct utility rules unless substantial infill fees are paid.

Tasmania

• Vehicle Reclassification Trigger: Mobile tiny homes are exempt from building approvals only while they maintain towable vehicle status with intact running gear. Anchoring the structure, removing the wheels, or hard-connecting it to a mains sewer or septic tank triggers an automatic reclassification as a permanent building under the National Construction Code.
• Proposed 90m² Expansion: The state is processing a planning amendment to expand the maximum size of secondary residences from 60 to 90 square metres. However, any project designed over 60 square metres prior to the official late-2026 gazettal is locked out of the fast track and requires a full discretionary application.
• 30-Day Annual Occupancy Cap: Standard municipal by-laws restrict unpermitted mobile living for off-grid THOWs. A self-contained vehicle can only be occupied on private land for a maximum of 30 total days per calendar year; exceeding this limit requires a formal licence or temporary occupancy permit.
• South Australia Contrast: Once Tasmania’s 90-square-metre expansion takes effect, it will become the most generous state for secondary floor space, eclipsing SA’s 70-square-metre limit. However, South Australia offers a much faster immediate track, allowing 70-square-metre builds via its Deemed-to-Satisfy system, while Tasmania forces a discretionary process for anything over 60 square metres.

Queensland

• Subordinate Dwelling Criteria: To avoid council infrastructure levies ranging from $15,000 to $30,000, a fixed tiny home must remain classified as a secondary dwelling rather than a dual occupancy. This requires staying under local floor limits, sharing a driveway, and using sub-meters linked to the primary household utilities.
• Short-Stay Mobile Curfews: Local authorities enforce highly fragmented rules for tiny homes on wheels. Unpermitted stays on private lots are capped at tight limits, such as a maximum of 4 weeks per year under the Sunshine Coast Council or 2 weeks per 8-week window in Gympie.
• Rural Workers Deregulation: To assist agricultural harvesting, state regulations exempt THOWs used for seasonal worker housing from development applications until December 2, 2026. This exemption applies directly to working farms, provided the site maintains basic sanitation and water safety standards.
• South Australia Contrast: Both states impose substantial infrastructure and utility levies on fixed builds. However, South Australia provides uniform, state-wide “Deemed-to-Satisfy” rules for units under 70 square metres, contrasting sharply with Queensland’s decentralized council framework that subjects builders to varying local sizes, stay caps, and unpredictable infrastructure bills.

Australian Capital Territory

• 500m² Lot Floor and Mandatory DAs: The Territory Plan prohibits building or occupying a self-contained secondary residence on any block under 500 square metres. The ACT lacks automatic planning exemptions, requiring both a formal Development Application for planning consent and a separate Building Approval for construction safety.
• Mandatory Tenant Parking Quotas: Property owners must allocate a dedicated off-street parking space exclusively for the tiny home tenant. This space must be in addition to the primary home’s parking requirements and cannot sit unscreened within the front boundary zone unless hidden by heavy landscaping.
• Private Open Space Siting Directive: Tiny home tenants must have a dedicated outdoor space of at least 28 square metres with a minimum clear dimension of 4 metres. Territory laws mandate that this space be directly accessible from and adjacent to a core living room rather than a bedroom, banning detached layouts.
• South Australia Contrast: The ACT enforces a highly rigid framework by completely blocking secondary residences on lots under 500 square metres and requiring a double-layer approval process. In contrast, South Australia fast-tracks backyard units up to 70 square metres via the PlanSA digital system without separate tenant parking quotas or rigid room-adjacency rules.

To learn more, read our post on tiny home regulations in the ACT.

Northern Territory

• Cyclonic Region C Building Mandate: Any fixed tiny home built within the territory’s northern coastal zones must fully comply with severe Region C cyclonic building rules. Securing a permit requires certified heavy-duty structural steel framing, roof tie-downs, reinforced footings, and debris-impact resistant windows and cladding.
• Municipal Developer Contribution Levies: Local councils can issue expensive Developer Contribution Notices when an additional residential unit is attached to an existing title. This legally bills the property owner for the projected extra load the tiny home places on shared public roads, stormwater channels, and parks.
• Capital Contribution Grid Fees: Even if a tiny home runs off a private electrical sub-meter to avoid a new grid application, the Power and Water Corporation can issue heavy Capital Contribution charges. These fees apply if the development strains or requires upstream upgrades to the local electricity grid.
• South Australia Contrast: The NT imposes heavy structural and financial hurdles, including mandatory developer contributions and cyclonic engineering mandates. South Australia operates under a centralized system with standardized “Deemed-to-Satisfy” rules for units under 70 square metres. While SA imposes a fixed $5,120 water connection charge, it lacks the unpredictable upstream power grid fees and municipal capital works bills seen in the NT.

FAQs

What permits do I need for a tiny house in South Australia?

To build a fixed tiny home, you’ll need full Development Approval via the PlanSA portal, which consists of two mandatory parts: Planning Consent (permission to use the land) and Building Consent (a check that the structure is safe). Once these are secured, you must also obtain Wastewater Approval from your local council’s health department as a mandatory final step before plumbing work begins. While tiny homes on wheels haven’t permit needs for short visits, you’ll need to apply through PlanSA to live in one permanently. It’s best to check with your council first as they’re the ones who confirm specific local fees.

Can I live in a tiny house full-time in South Australia?

Yes, you can live in a tiny house full-time provided it meets the state’s building and zoning rules. Tiny homes on foundations’re the simplest to approve for full-time living because they can be classified as a permanent Class 1a dwelling or a secondary “ancillary” home. 

Tiny homes on wheels are usually treated as caravans and they’re generally restricted to short-term stays unless you have a specific permit or the home is used as a temporary residence while you rebuild after a natural disaster.

Do mobile tiny homes need a building permit?

Because a tiny home on wheels is technically a vehicle, it won’t usually need a standard building permit like a fixed house does, provided it stays truly mobile and meets road-legal standards. However, the moment it is occupied as a permanent, independent primary residence, it triggers a Change in Land Use requiring Planning Approval under the PDI Act 2016. If you connect it to rigid, permanent onsite plumbing rather than flexible caravan-style hoses, it loses its mobile status and is reclassified as a permanent building that must undergo full Building Consent against the National Construction Code. It’s always a good idea to contact your council’s planning department to see if they’ve any specific bylaws for moveable dwellings in your area.

Are there zoning restrictions for tiny homes?

Yes, there’re zoning rules that determine where you can place a tiny home, particularly if it’s a fixed structure. Most residential zones allow tiny homes as “ancillary accommodation” (granny flats) as long as they meet the Planning and Design Code standards for things like setbacks and height. 

You should check the South Australian Property and Planning Atlas (SAPPA) to see if your land has “special controls,” such as bushfire overlays or heritage rules, which could add extra requirements to your project.

Can I rent out my tiny home?

Yes, recent reforms in South Australia mean you can now rent out a self-contained tiny home to any tenant on the open market under the Residential Tenancies Act 1995. You’re no longer restricted to only housing family members, but your tiny home must be approved as a habitable dwelling and meet minimum standards for kitchens and bathrooms. 

If you’re planning on using it as a short-term holiday rental (like an Airbnb), you should check with your council to see if they’ve any specific registration rules for tourist accommodation.

What about off-grid tiny homes?

Off-grid systems like solar panels and rainwater tanks are generally encouraged, but you’ll still need council and health department approval for your wastewater management. This ensures that your sewage and sink water are handled in a way that isn’t harmful to the environment or your neighbors. 

You’ll usually need to submit a simple waste-management plan that proves your system meets the standards set by SA Health and the Environment Protection Authority (EPA).

Will my secondary dwelling in South Australia be rated separately by council?

Yes, once your tiny home is approved and occupied, most South Australian councils will issue a separate assessment for it, which means it’ll likely have its own rates notice. 

This is because the law allows councils to charge rates based on separate “occupation,” especially if you’re renting the space to someone else. It’s a good idea to speak with your local council’s rating department early on so there isn’t any surprise when your yearly bill arrives.
