A certifier's summary - Queensland
Building work in Queensland requires a building approval (BA).
The Building Act 1975 governs BAs for Queensland. As per the Building Regulations 2021 (Schedule 1) there is some work which is prescribed. Prescribed work is considered low risk and may not trigger an approval.
Q: When is a BA not required?
A: When all of the scope of work fits in to the work identified in the Building Regulations 2021 (Schedule 1).
Even if an approval is not required, work should be undertaken
- with a contract, with QBCC insurance paid.
- by QBCC licensed contractors, acting within their scope.
A RPEQ engineer will be required to design and inspect all structural elements to ensure structural stability.
Examples of prescribed work (ie not requiring a BA)
minor structures or repairs that are self-assessable
repairs/ maintenance to existing buildings
fences under 2m (not including swimming pool fencing)
retaining walls - approval is only required where a retaining wall
exceeds 1m in total (height)
is within 1.5m of a structure
includes a footing that will impose a surcharge loading to any nearby infrastructure/footings.
However, if even one element of the project is out of the scope outlined in the Building Regulations 2021, Schedule 1 it does trigger the need for approval.
For example, if a retaining wall is 900mm high, but only 1m away from another structure, a building approval is required.
For other class 10 structures, dimensions and/or location may help decide if a building approval is/ is not required.
