What Happens If You Build a Shed Without Council Approval?

Skipping council approval on a new shed feels like a shortcut. No site visit, no waiting on paperwork, no explaining your plans to a stranger with a clipboard.

It rarely stays that simple. Sheds built without the right approval get flagged by neighbours, picked up during a property sale, or discovered the hard way when an insurance claim is denied.

By then the shortcut has cost more than the approval process ever would have. Councils in Western Australia and South Australia can issue fines, demolition orders, or force you to pay for a retrospective approval that is slower and more expensive than doing it properly from the start.

This guide sets out exactly what happens if you build a shed without council approval, how the rules differ between WA and South Australia, and where the genuine exemptions sit so you are not paying for permissions you never actually needed.

What Happens If You Build a Shed Without Council Approval

Building a shed without council approval can lead to steep fines, a formal order to modify or remove the structure, complications when selling your property, and denied insurance claims if the unapproved shed causes damage or injury.

Most unapproved sheds are not caught straight away. They tend to surface later, during a neighbour dispute, a routine council inspection, or when a property goes on the market, and by then the options are more limited and more expensive.

Legal and Financial Penalties

• Fines. Local councils in WA and South Australia can issue infringement notices or pursue prosecution for building work carried out without the required permit or approval, with penalties that scale sharply for repeat or deliberate non-compliance.
• Demolition or Modification Orders. If your shed does not meet setback, height or safety requirements, council can issue a building order process requiring you to modify or remove it, at your own cost.
• Retrospective Approval Costs. Applying for approval after the shed is already built usually means engaging an engineer or building surveyor to certify the structure, on top of the standard permit fees you would have paid anyway.

Property and Insurance Risks

• Insurance Claims Denied. Most home and contents policies expect structures to comply with building regulations, so a storm, fire or liability claim linked to an unapproved shed can be refused outright.
• Trouble Selling. An unapproved shed often surfaces during conveyancing, and buyers or their bank can use it to renegotiate price, delay settlement, or walk away from the sale entirely.

None of this means every shed needs a full application. It means the risk of skipping one is real enough to check first, especially once your build starts pushing size or height limits.

Do You Need Council Approval for a Shed?

In most cases, yes. Whether you’re planning a straightforward shed builder project, want carport builders Perth can quote on, a barn shed for equipment, or livable sheds for extra living space, the approval question applies before the first sheet of steel goes up.

Exactly what triggers approval comes down to three things: floor area, height, and how close the structure sits to a boundary or another building. Get any one of these wrong and an otherwise “exempt” shed can still need a permit.

It also helps to separate two different approvals. A building permit checks the shed itself is structurally sound. A planning approval checks where it sits on your block relative to boundaries, other buildings and your zoning. Many owners assume clearing one covers the other, and that mismatch is a common reason a shed ends up unapproved without anyone realising it.

Some structures genuinely do not need either. A small garden shed well within your council’s size and setback limits, on a standard residential block, can often go up without paperwork. The mistake most owners make is assuming this applies everywhere, when it depends entirely on your specific block and local government area.

If you are unsure where your project sits, our guide on whether you need council approval walks through the general decision process in more detail.

How to Get Council Approval for a Shed

The process is more predictable than most people expect once you know what to prepare. Missing paperwork, not a complicated process, is what causes most delays.

A typical application includes a detailed site plan showing the shed’s position relative to boundaries and existing buildings, engineering documentation for the structure itself, and details of the shed’s intended use.

Your council assesses this against setback rules, height limits and any overlays that apply to your property, such as bushfire risk or heritage zoning, before issuing approval.

Timeframes vary by council and current workload, so it is worth applying with enough lead time before you want construction to start, rather than treating approval as a formality you can rush through at the end.

If council comes back with requested changes, that is rarely the end of the process. Most applications only need revising and resubmitting, not starting again from scratch, provided the underlying design was sound to begin with.

Reputable shed suppliers provide engineering documentation as standard, which removes one of the more time-consuming parts of the application. For a closer look at when a permit for a domestic shed is required in the first place, see our dedicated guide.

Shed Regulations in WA and South Australia

Shed rules are not national. What is exempt in one state can require a full development application in another, so it pays to check the rules for where you are actually building rather than relying on general advice.

Council Approval for a Shed in WA

In Western Australia, a single shed with a floor area of 10m² or less and a height of 2.4m or less is generally exempt from needing a building permit under the state’s building regulations.

Planning approval is a separate question. To stay planning-approval-free as well, a shed typically needs to sit in a residential zone, behind the front setback line, and clear of neighbouring buildings and boundaries by the shed size and setback limits your specific council applies, which can vary between local government areas.

Anything larger, taller, in a bushfire-prone area, or on a non-residential block will usually need a building permit, a planning permit, or both. Non-compliant structures can also be hit with a formal notice from council, sometimes with a set number of days to bring the shed into compliance or remove it.

Under WA’s Building Act 2011, penalties for carrying out building work without a required permit can run into tens of thousands of dollars, on top of whatever it costs to fix or remove the structure afterwards.

Shed Regulations in South Australia

South Australia takes a similar approach with a different threshold. A detached, non-habitable outbuilding such as a garden shed can qualify as exempt development if its floor area is 15m² or less and it does not exceed 2.5m in height.

That exemption does not apply everywhere. Flood zones, the Hills Face Zone and heritage areas carry stricter rules, and some heritage-designated areas cap exempt sheds at 10m² instead of 15m².

Building without the required approval in South Australia is not a minor risk either. Under South Australia’s building penalties, a person convicted of unauthorised development can face a fine of up to $120,000, with additional daily penalties for as long as the breach continues.

If your planned shed sits anywhere near these thresholds, it is worth confirming with your council before you commit to a size or location.

How Close Can a Shed Be to a Fence?

Boundary setbacks are one of the most common reasons a shed that looks exempt on paper still ends up needing approval. Size and height are not the only conditions that matter.

In WA, many councils require sheds to sit at least 900mm from a boundary or neighbouring building to remain planning-approval-free, though this varies and some allow closer setbacks for smaller structures under local planning policy.

In South Australia, setback requirements are generally set at the council level as part of the exempt development conditions, so the safe distance from a fence can differ from one local government area to the next.

A shed built hard against a boundary can also raise practical issues beyond approval, including drainage runoff onto a neighbour’s property and reduced access for maintenance. If a patio approval process is already underway for the same property, it is worth checking setback rules for both structures together, since councils often assess site coverage as a whole.

Do You Need a Permit to Build a Shed on a Rural Property?

Rural land is often assumed to sit outside council oversight, and that is not accurate. Zoning changes which rules apply, but it does not remove the need to check them.

A large hay shed or machinery shed on a farming property can still exceed the size and height thresholds that trigger a building permit, particularly once floor area climbs into the hundreds of square metres.

What does change on rural land is the reasoning behind the rules. Setbacks account for machinery access and firebreaks rather than neighbour privacy, and bushfire-prone area requirements are more likely to apply given the typically larger, more exposed sites.

Primary production zoning can also open up a different assessment pathway to a standard residential block, but that pathway still involves an application, not an automatic pass. Confirming zoning and land use with your council before you design is a far cheaper step than finding out afterwards.

Stables and equestrian structures follow the same logic. Working with experienced stable builders means someone has already thought through the typical requirements, but the property’s zoning, not just the building’s size, ultimately determines what approval process applies.

Frequently Asked Questions

Get Your Shed Approved Before You Build

The paperwork behind a shed is rarely the hard part. Knowing which rules actually apply to your property, in your state, is where most owners get caught out.

Skipping council approval does not remove the requirement. It just delays the cost and adds fines, orders or a stalled property sale on top of it.

Checking the rules before you build, rather than after, is the difference between a straightforward approval and an expensive retrospective one. For most owners, that check takes a phone call. Fixing an unapproved shed later rarely does.
