Do I Need to Submit a Statement of Environmental Effects (SEE) with my DA?

If you're preparing a development application in NSW, you're probably wondering whether you need to include a Statement of Environmental Effects (SEE).

Yes, in most cases, a SEE is a mandatory part of your DA submission.

It explains how your proposed development aligns with local planning controls and what impacts it may have on the surrounding environment.

A clear, detailed SEE helps your application progress more smoothly through the council approval process.

Here's what you need to know.

1. What is a Statement of Environmental Effects?

A SEE is a written report that accompanies your DA and outlines how the development will comply with the NSW planning framework.

It addresses issues like traffic, noise, overshadowing, privacy and streetscape impact.

For example, if you're planning a dual occupancy on a narrow block, your SEE must show how you'll minimise impacts on neighbouring properties.

The SEE also explains how your design responds to zoning, building height, setbacks and other local development controls.

2. When is a SEE required?

Almost all types of development applications in NSW require a Statement of Environmental Effects.

Whether you're building a new house, adding a second storey or converting a garage to a granny flat, a SEE is usually expected.

Some minor works, like small pergolas or fences, may be exempt but it's best to check with a planning consultant.

Town Planning Sydney often helps clients determine whether a SEE is needed and prepares these reports as part of our DA support service.

3. What should the SEE include?

The level of detail depends on the scale and complexity of your project.

A basic residential DA might need a 5-10 page SEE, while larger developments like townhouses or mixed-use buildings may require a more extensive report.

At a minimum, your SEE should cover:

• Site description and existing conditions

• Project summary and design rationale

• Assessment against local planning controls (LEP, DCP, SEPPs)

• Potential environmental impacts and mitigation measures

• Justification for any non-compliances

  
  

4. Who can prepare a SEE?

While there's no legal restriction on who can write a SEE, councils expect it to be thorough, accurate and professionally formatted.

Many applicants engage a planning consultant to ensure the SEE meets council standards.

Town Planning Sydney provides in-house preparation of Statements of Environmental Effects, backed by years of experience navigating the NSW planning system.

This can help avoid unnecessary delays or requests for additional information.

5. How a good SEE supports DA approval

A well-prepared SEE shows council that you've considered all relevant planning issues and designed your project responsibly.

It reduces the likelihood of council objections and can help you respond effectively to any public submissions.

In one recent case, we supported a client seeking DA approval for a childcare centre in a residential zone.

The SEE clearly addressed noise, traffic, landscaping and neighbourhood character concerns, helping the project gain approval despite initial objections.

Whether you're submitting a basic dwelling DA or a more complex commercial application, good planning advice is key.

Town Planning Sydney is here to guide you through the entire development application process, from early design to final council approval.

If you're unsure about your SEE or need help preparing one, speak to an experienced planning consultant before you lodge your DA.
