Nothing kills the excitement of a new shed project faster than getting a letter from council telling you to pull it down. I’ve seen it happen to a mate in Logan — built a beautiful 6x9m shed without approval, and council made him relocate it at his own expense because it was too close to the boundary.

The regulations in Queensland aren’t complicated, but they’re strict about certain things. Here’s what you need to know before building a shed over 10 square metres.

The 10 Square Metre Threshold

In Queensland, sheds (classified as “Class 10a buildings”) under 10 square metres are generally exempt from building approval if they meet basic requirements:

• Not more than 2.4m high at any point
• Not attached to the house
• Located behind the building line
• Minimum setbacks from boundaries observed

Once you exceed 10 square metres — and most useful workshops do — you enter building approval territory. A 3x4m shed (12 sqm) needs approval. So does the 6x6m or 6x9m workshop most people actually want.

What You Need: Building Approval

For sheds between 10 and 200 square metres, you typically need building approval but not planning approval (development approval), provided the shed complies with the Queensland Development Code (QDC) and your local council’s planning scheme.

Building approval requires:

Structural plans: Either engineered plans specific to your shed or manufacturer-supplied plans that comply with Australian Standards. Most kit shed suppliers (Ranbuild, Fair Dinkum Sheds, Totalspan) provide compliant plans with their products.

Site plan: Shows where the shed will sit on your property relative to boundaries, the house, and other structures.

Building application form: Submitted to either your local council or a private building certifier.

Fees: Council fees vary but expect $300-800 for a standard domestic shed. Private certifiers may charge more but are often faster.

Timeframe: Council processing typically takes 2-6 weeks. Private certifiers can often turn approvals around in 1-2 weeks.

Boundary Setbacks

This is where most people get into trouble. Queensland requires minimum distances between sheds and property boundaries.

The specific setbacks depend on your local council’s planning scheme, but as a general guide:

Side boundaries: Typically 1.5m minimum for sheds under 4.5m high. Some councils allow reduced setbacks (down to 0m for certain outbuildings) under specific conditions.

Rear boundary: Often 1.5m minimum, though some councils allow sheds on or near rear boundaries under the “accepted development” provisions of the QDC.

Front boundary (building line): Sheds must be behind the front building line. This varies by council and lot size but is typically 6m from the front boundary.

Distance from the house: Some councils have requirements about proximity to the main dwelling, particularly if the shed is near the house’s windows or outdoor living areas.

Check your specific council. Brisbane City Council, Logan, Gold Coast, Moreton Bay, Ipswich, and Sunshine Coast councils all have slightly different requirements. Don’t assume what applies in one LGA applies in another.

Height Restrictions

Maximum height is typically:

Wall height: 3.0-3.6m for domestic outbuildings in most council areas.

Ridge height: 4.0-4.5m maximum.

If you want a high-clearance shed (for a boat or caravan, for example), check that your intended height complies before ordering. A 3.6m wall height with a pitched roof can easily exceed 4.5m at the ridge.

Slab and Foundation Requirements

Sheds over 10 sqm on a concrete slab need the slab to comply with AS 2870 (Residential Slabs and Footings). This usually means:

• Minimum 100mm thick reinforced concrete slab
• Engineer-designed if on reactive soils (common in Queensland)
• Proper drainage away from the slab

Most kit shed suppliers specify slab requirements in their engineering documentation. Follow these exactly — a non-compliant slab can void the engineering certification of the shed structure.

If you’re doing a gravel or compacted earth floor (acceptable for some carport and open-sided structures), the footing requirements are different. Concrete piers or strip footings at column locations are typical.

Electrical Considerations

If your shed will have electrical wiring, it needs to comply with AS/NZS 3000 (Wiring Rules) and be installed by a licensed electrician. The electrical work requires its own inspection and compliance certificate.

This is separate from the building approval but equally mandatory. I covered electrical setup in detail in my workshop setup guide, but the key point is: don’t run power to your shed yourself. It’s illegal in Queensland and genuinely dangerous.

Plumbing

If you’re adding plumbing to your shed (sink, toilet, wash bay), you’ll need plumbing approval and the work must be done by a licensed plumber. This is separate from building approval and has its own compliance requirements.

Most workshop sheds don’t need plumbing, but if you’re building a workshop that doubles as a man cave or hobby space, a sink is handy. Just factor the approval into your planning.

Fire Separation

If your shed is within 900mm of a boundary or within 1.8m of the dwelling, fire separation requirements apply. This typically means:

• Fire-rated wall construction on the boundary-facing side
• No openings (doors, windows) in walls within certain distances of boundaries
• Specific cladding requirements

These requirements exist because a fire in a shed near a boundary threatens the neighbour’s property, and a fire in a shed near the house threatens the dwelling.

Common Mistakes

Building without approval. “She’ll be right” is not a building compliance strategy. Councils do enforce, and the consequences range from fines to demolition orders. Neighbours who are annoyed by your shed will absolutely report you.

Ignoring setback requirements. Even a few centimetres too close to a boundary can trigger enforcement. Measure carefully and verify with your certifier before pouring the slab.

Not checking easements. Many Queensland properties have easements (utility corridors) where you can’t build. These aren’t always obvious from looking at the property. Check your title survey or request a property plan from your local council.

Forgetting about stormwater. A 6x9m shed collects a lot of rainwater. In Queensland, you’re typically required to manage stormwater from your shed — either connecting to the stormwater system or directing it appropriately. Dumping it onto a neighbour’s property will create problems.

Assuming heritage or character overlays don’t apply. Some suburbs have character or heritage overlays that impose additional restrictions on outbuildings — height limits, material requirements, or even colour restrictions. Check your property’s overlay before finalising plans.

The Approval Process Step by Step

1. Check your council’s planning scheme. Most councils have online planning scheme maps where you can check what’s permissible on your property. Look up your lot and check overlays, setbacks, and accepted development criteria.

2. Get quotes from shed suppliers. Reputable suppliers (Ranbuild, Fair Dinkum Sheds, ShedSafe-accredited manufacturers) provide engineering documentation that complies with Queensland building requirements.

3. Engage a building certifier. Either your local council or a private certifier. They’ll assess your plans and site layout for compliance.

4. Submit your application. Plans, site layout, engineering documentation, and fees.

5. Wait for approval. Don’t start construction until you have written approval. Seriously.

6. Build according to approved plans. Don’t change dimensions, location, or specifications without amending the approval.

7. Get inspections. Your certifier will specify inspection stages (typically footing/slab stage and completion). Don’t skip these.

8. Get your final certificate. This confirms the shed was built in compliance with the approval. You’ll need this if you ever sell the property.

Is It Worth the Hassle?

Yes. The approval process for a standard domestic shed is straightforward and relatively inexpensive. The shed suppliers do most of the heavy lifting with engineering documentation. A good building certifier guides you through the rest.

The alternative — building without approval — creates legal liability, potential fines, insurance complications (insurers may refuse claims for unapproved structures), and problems when selling your property.

Spend the $500-800 on proper approval. It’s a tiny fraction of the total shed cost and saves potential headaches worth many times that amount.
