Do I need approval for a shed in Brisbane?
Shed approvals · Updated · 6 min read · BWG Sheds
Short answer
In Brisbane a shed needs no building approval only if it has a plan area of 10 m² or less, is no more than 2.4 m high with a mean height of 2.1 m or less, has no side longer than 5 m and does not affect other structures or a pool fence. Larger sheds need building approval from a certifier. On the planning side council says sheds are generally accepted development, subject to requirements in residential zones.
- Building exemption: 10 m² plan area, 2.4 m high, mean height 2.1 m, no side over 5 m.
- Planning: sheds are generally accepted development, with requirements in residential zones.
- On lots under 450 m² (rear lots under 600 m²) City Plan's small-lot code prevails over the QDC.
- A certifier can seek alternative provisions, such as a reduced boundary setback, through a council referral.
- Amenity and aesthetics referral can apply in rural, rural residential, character and some residential areas.
Building approval in Brisbane
Brisbane City Council's shed page lists the conditions under which you do not need building approval: a plan area of no more than 10 m², a height of no more than 2.4 m with a mean height of no more than 2.1 m, no side longer than 5 m, no effect on the structural integrity of other structures, and no change to a pool enclosure or pool fence. This is the state-wide small-shed exemption in Schedule 1 of the Building Regulation 2021. Brisbane sits in wind Region B1 on Geoscience Australia's indicative map, so the cyclonic-region exclusion does not bite here.
A double garage, workshop or anything bigger than a garden shed needs building approval from a building certifier, who assesses the plans against the building codes and inspects the work at the required stages.
Planning rules for residential zones
Council describes sheds as generally accepted development under City Plan 2014, subject to requirements if the property is in a residential zone. In practice that means the shed has to meet the acceptable outcomes of the relevant code, such as the dwelling house codes, for height, setbacks and site cover. Where it does not, council becomes involved through a referral rather than a full planning application in most cases.
| Question | Brisbane answer |
|---|---|
| Small garden shed (10 m², 2.4 m, no side over 5 m) | No building approval, must still comply |
| Garage, workshop or larger shed | Building approval from a building certifier |
| Planning approval | Generally accepted development; requirements apply in residential zones |
| Lot under 450 m² (rear lot under 600 m²) | City Plan small-lot code prevails over the QDC |
| Shed closer to the boundary than the code allows | Certifier can lodge a request for a referral response |
Setbacks, small lots and referrals
On a standard lot the Queensland Development Code siting rules apply: a 1.5 m side and rear clearance, with a Class 10a shed allowed inside it if it is no more than 4.5 m high (mean 3.5 m), buildings inside the clearance total no more than 9 m along that boundary, and it stays 1.5 m from a neighbour's habitable-room window. On a small lot, which Brisbane defines as under 450 m² or a rear lot under 600 m², City Plan's Dwelling house (small lot) code prevails over the QDC.
Council notes that your building certifier can seek alternative provisions, such as a different setback from the boundary, by lodging a request for a referral response. Separately, City Plan's amenity and aesthetics referral can apply to Class 10 work in the Rural, Rural residential, Environmental management and residential zones, in the Traditional building character overlay and in neighbourhood plan areas, where the work does not comply with the listed codes' acceptable outcomes.
Working with a tight Brisbane lot or a character street? We design to the setbacks first, so the application is straightforward.
Council approval assistanceBefore you choose a shed position
- Look up the zone and overlays for your lot in City Plan's online mapping.
- Measure the longest wall you want on or near a boundary, and add any existing garage or carport already in the clearance.
- Check for sewer, stormwater and easements running through the yard.
- Note the neighbours' windows near the proposed shed.
- Decide how the shed will be used; a Class 10a shed is non-habitable.
Requirements depend on your property, proposed structure and local planning/building controls.
After the approval: inspections and site cover
Once the certifier issues the building approval, the work is inspected at set stages. For a Class 10 building such as a shed or garage, the footing or slab excavation stage must be inspected against the approval before concrete is poured, so plan your concreter's booking around it. The certifier does not need to appoint a separate competent person for those Class 10 inspections.
Site cover is the other number that trips up suburban projects. Under QDC MP 1.2 the area covered by all roofed buildings and structures on a lot of 450 m² or more must not exceed 50% of the lot. On a Brisbane block that already has a house, a patio and a carport, a large garage can push you over. City Plan's codes and any small-lot rules apply as well, so check the whole site, not just the new shed.
