Statement of Environmental Effects - NSW
Set your project up for success.
A Statement of Environmental Effects (SEE) is arguably the most important component of a Development Application.
Think of it as the story that explains your project to council - what you’re proposing, how it complies with planning rules and why it deserves approval.
Architectural drawings show the “what,” while the SEE covers the “why” and “how.”
You’ll need an SEE whenever you lodge a DA, whether that’s for a new home, a shop fit-out, a subdivision or a change of use.
Councils require it under the Environmental Planning and Assessment Act 1979, so skipping it isn’t an option.
The document sets out how the proposal meets the relevant Local Environmental Plan (LEP), Development Control Plan (DCP), and State Environmental Planning Policies (SEPPs).
It addresses impacts like traffic, parking, privacy, overshadowing and neighbourhood character.
A well-prepared SEE can make the difference between a smooth approval and a drawn-out refusal.
Viability of approval is usually strong if the SEE is clear, addresses all controls and tackles potential non-compliances head-on with reasoned justification.

Frequently Asked Questions
for Statements of Environmental Effects
Is a Statement of Environmental Effects (SoEE) mandatory for all DAs in NSW?
Yes. Under the Environmental Planning and Assessment Regulation 2021, an SoEE is a mandatory requirement for all Development Applications in New South Wales. It serves as the primary document that justifies your proposal against local and state planning controls.
What is the difference between an SoEE and a Preliminary Planning Report?
While often used interchangeably, an SoEE is the formal legislative requirement for a DA. A Planning Report is a broader term that may include feasibility studies or pre-lodgement advice. An SoEE specifically addresses the Environmental Planning and Assessment Act 1979 and local LEPs/DCPs.
How does an SoEE address non-compliance with a Development Control Plan (DCP)?
If a project doesn't meet a specific DCP control (like a setback or building height), the SoEE must provide a "Merit-Based Assessment." This justifies why the proposal should be approved by demonstrating that it still achieves the underlying "objectives" of that control despite the numerical variation.
Does a Complying Development Certificate (CDC) require an SoEE?
Generally, no. A CDC is a fast-track approval process assessed against set standards in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008. However, a "Statement of Environmental Effects" or "Statement of Compliance" is often requested by Private Certifiers to clearly map out how the project meets those standards.
Can I write my own Statement of Environmental Effects?
While a homeowner can technically write their own, it is not recommended for complex projects. Professional Town Planners understand the nuances of Case Law and Land and Environment Court principles, which are often necessary to successfully argue for variations or "merit-based" approvals.
What specific legislation should be cited in an NSW SoEE?
A comprehensive SoEE must reference the Environmental Planning and Assessment Act 1979, the relevant Local Environmental Plan (LEP), the Development Control Plan (DCP), and applicable State Environmental Planning Policies (SEPPs) such as the Housing SEPP or the Biodiversity and Conservation SEPP.

Risks & Challenges
Statement of Environmental Effects challenges.
The main challenge with an SEE is ensuring it addresses every relevant planning control. Missing details like setbacks, height limits or parking can trigger council requests for further information, delaying the process.
Another risk is underestimating environmental impacts. If privacy, overshadowing, traffic or noise aren’t properly assessed, objections from neighbours or council officers can arise.
There’s also the complexity of incorporating multiple layers of legislation. Between LEPs, DCPs and SEPPs, it’s easy to overlook a key clause without professional guidance.
For heritage, bushfire or flood-affected sites, specialist reports will also be required to back up the SEE.
The risk of refusal is real if non-compliances aren’t justified. A strong SEE doesn’t just list facts, it argues your case. Without that, council can determine that the development fails to meet objectives, which means costly redesigns or appeals.
