Development approvals are not always permanent or unchangeable. Queensland's Planning Act 2016 provides mechanisms for changing a development approval after it has been issued, including minor change applications and extension applications. Whether you can change your approval, and how, depends on the nature of the change, when the approval was granted, and the relevant provisions of the planning scheme.
Two main change pathways
The Planning Act provides for change applications, which alter the substance of the approval (the design, the conditions, the use), and extension applications, which extend the period within which the approval remains valid. These are different processes with different tests and different lodgement requirements.
Change applications are further divided based on whether the change is minor or other than minor. Minor changes have a simpler process; non-minor changes are treated more like a new application in many respects.
The minor change test
A change is considered minor if it: does not result in substantially different development; does not require referral to a referral agency that was not previously involved; does not require additional public notification; and does not change the type of approval. The test is intentionally restrictive, many changes that appear small in commercial terms fail the minor change test.
Where a change qualifies as minor, the application is processed as a relatively contained matter. Where it does not qualify, the application is other than minor, which typically requires re-notification and a more substantive reassessment.
Extension of currency
All development approvals lapse after a defined period unless development is substantially commenced. The default is four years for most approvals. Where the period is approaching expiry, an extension application can be lodged to extend the currency period.
The extension application is assessed against the current planning scheme (not the scheme that applied at the time of the original approval). Where the scheme has changed substantially in the intervening period, this can affect the prospects of the extension being granted.
When to use which
If the project itself has changed but is still proposed within the current period, a change application is required. If the project is the same but more time is needed, an extension is required. Both can sometimes be lodged together where both adjustments are needed.
The strategic timing matters. Lodging an extension just before expiry is normal practice; lodging substantive changes mid-period is also normal. Lodging close to a planning scheme amendment that may affect the project is a common reason to act sooner rather than later.
Approvals are not set in stone, but the change pathways are technical and the tests applied are demanding. Where a change to an existing approval is being contemplated, professional advice on the appropriate pathway and the prospects of success is the right first step.
