Can I Make Changes After my DA is Approved?

In NSW, you can make changes after your development application (DA) is approved, but not all modifications are treated the same.

Councils categorise changes as either minor or substantial. Some can be approved quickly, while others may require a new application or formal modification process.

Speaking with a town planner NSW based can help you understand the safest way forward.

If the change is minor and does not alter the building footprint, height or impact on neighbours, you may be able to submit what’s called a Section 4.55(1) modification.

This is for minimal adjustments, such as internal reconfiguration or changing a window. These can often be approved with minimal documentation and no new public notification.

We recently assisted a client with a council submission for secondary dwelling NSW who wanted to flip the kitchen and living area after DA approval.

The revised plan was lodged with a brief letter and approved under Section 4.55(1) in less than three weeks. Our planning consultant prepared the request and confirmed the change did not trigger further assessment.

More significant changes require a Section 4.55(2) modification.

These are used when changes affect the external appearance, setbacks or floor area, but still keep the proposal substantially the same.

In this case, you will need updated plans, a revised statement of environmental effects for NSW DA, and possibly a new round of public notification. Our town planning services for residential development NSW cover this type of amendment regularly.

If the proposed changes are extensive or fundamentally alter the project, the council may determine that a new development application is required.

This is more likely if you increase the number of storeys, reduce landscaping or breach height controls. A Clause 4.6 variation request NSW may also be needed if you no longer comply with the planning standards.

In heritage areas, even small design changes may require a new heritage impact statement NSW town planning, especially if the materials or roof form are modified.

If your DA involved sensitive design elements, a town planner near me specialising in NSW DCP can review the proposed amendments and confirm what documentation is needed.

If you are unsure how to get a DA approved in NSW, or how to modify an existing approval, timely planning advice is the best way to stay compliant and avoid delays.

Whether you are dealing with a planning permit NSW, commercial change of use, or subdivision, a NSW town planning consultant for subdivision approval can manage the process and keep your project on track.
