Do I need council approval for a shed in Queensland?

The short answer: most sheds need building approval

Queensland treats a shed, garage or carport as a Class 10a building under the National Construction Code: a non-habitable building such as a private garage, carport, shed or the like. Building work on a Class 10a building needs a building approval unless the Building Regulation 2021 says otherwise. For a typical backyard shed, the only general exemption is the small-shed rule in Schedule 1, section 13.

Two details catch people out. First, plan area is measured to the extremities of the finished structure, so the roof overhang counts. A 3 m × 3.3 m shed with a 300 mm overhang all round is no longer under 10 m². Second, the exemption removes the need for a building approval, not the need to comply. The shed must still meet the building assessment provisions, including structural adequacy for the site and the siting rules below.

Several councils repeat the same test in their own words. Sunshine Coast Council adds that the shed must also comply with minimum boundary setbacks, sit outside any registered easement and not trigger anything else under the Building Act, for example by loading a retaining wall or building over council stormwater or a sewer. If any one condition fails, the shed needs building work approval from a private building certifier.

Who actually gives the approval

Building approval in Queensland is issued by a building certifier. Certifiers are licensed by the QBCC and work either in private practice or for a council. They assess the application, decide whether to issue the building approval and inspect the work at the required stages. A certifier must not design the building or carry out the work, which is why your shed supplier cannot certify its own shed.

Many councils no longer assess building applications at all. Logan City Council says it does not provide building certification and that approval must come from a private certifier, and Redland City Council says the same. Council still matters, though, because of the planning side.

Building approval and planning approval are different things

A building approval checks the shed against the building codes. A planning approval checks it against the council's planning scheme: the zone, overlays such as flood or bushfire, heritage or character areas, and the scheme's own rules for outbuildings. A shed can be exempt from building approval and still need planning approval, or need a council referral, depending on the scheme. Where matters outside the building assessment provisions need planning assessment, the certifier must wait for the council's development permit before issuing the building approval.

In practice, most sheds on residential lots with an existing house are accepted development under the planning scheme, which means no separate planning approval. The exceptions are overlays and zones. Redland City Council, for example, notes that its Coastal Protection, Heritage, and Flood and Storm Tide Hazard overlays can raise the level of assessment, and that a shed on vacant land with no house can be treated as a different use altogether.

How close to the boundary can a shed go?

Siting has been governed by the Queensland Development Code MP 1.1 (lots under 450 m²) and MP 1.2 (lots of 450 m² and over). Under MP 1.2 the side and rear boundary clearance is 1.5 m where that part of the building is 4.5 m high or less. A Class 10a shed may sit inside that clearance if all of these hold:

• the part inside the clearance is no more than 4.5 m high with a mean height of no more than 3.5 m;
• the total length of all buildings inside the clearance is no more than 9 m along any one boundary;
• it is no closer than 1.5 m to a required habitable-room window of the neighbour's house.

MP 1.2 also caps the area covered by all roofed buildings at 50% of the lot. These are default standards: a council's planning scheme can set alternative siting rules that prevail, and Brisbane's small-lot code is one example. If a design does not meet the acceptable solutions, the certifier seeks a referral response from council on design and siting.

The Queensland Housing Code commenced on 1 September 2026 and replaces QDC MP 1.1 and MP 1.2. During the transition to 1 September 2029 it applies in a council area once that council's planning scheme has been amended to adopt it, so for now the rule that applies depends on your council. Your certifier will confirm which one governs your lot.

Things that change the answer on your block

• Wind region. In Region C the small-shed exemption does not apply at all, and the structure must be designed for cyclonic wind.
• Easements and infrastructure. Building over or near sewer, stormwater or an easement brings extra approvals.
• Overlays. Flood, bushfire, landslide, heritage and character overlays can require planning assessment or a particular construction standard.
• Zone. Rural and rural-residential zones often have their own setbacks and floor-area limits for outbuildings.
• Use. A shed is non-habitable. Using a Class 10a shed as a dwelling without approval is an offence under the Building Act 1975.

Requirements depend on your property, proposed structure and local planning/building controls.

What BWG Sheds does and does not do

We are not the approving authority. What we do is design the shed around your block and intended use, prepare the drawings and site-specific engineering documentation a certifier needs, and coordinate the application with a building certifier and, where the planning scheme requires it, with council. If council or the certifier asks for more information, we help answer it. The decision itself stays with the certifier and council, as it should.
