At Barr Planning, we recognise that every development impacts the communities it touches. Whether positive or negative, these impacts need to be understood, managed, and mitigated for balanced and sustainable outcomes. This is where Social Impact Assessment (SIA) becomes critical.
An SIA is a structured methodology that assesses the potential social effects of a development, particularly on vulnerable groups or communities. By analyzing both the positive and negative impacts, SIA helps enhance community benefits and provides strategies to manage any adverse outcomes.
The Key Benefits of SIA:
- Boost Job Opportunities & Economic Growth
- Plan for Social and Physical Infrastructure
- Strengthen Community & Stakeholder Relationships
- Deliver Balanced & Sustainable Development Outcomes
- Mitigate Social, Environmental, and Economic Risks
Not every development needs a full SIA. The scale and sensitivity of the project typically determine if an SIA is required. Developments that are large in scale, sensitive in nature, located in sensitive areas, or have impacts that standard consent conditions cannot address, generally require a detailed SIA.
Typical Development Types Needing an SIA:
- Tourist accommodations with 20+ rooms
- Affordable housing delivering more than 50 dwellings or lots
- Correctional facilities
- Large-scale educational establishments
- Gaming or package liquor outlets
- Planning proposals leading to 200+ lots
- State significant developments
- Medical centers
SIA Complexity: From Basic to Complex
Not all SIAs are the same. The scale and context of the project will dictate whether you need a basic or complex SIA.
A basic SIA typically provides a high-level summary of initial scoping and recommendations for managing minor impacts. For larger or more sensitive projects, a complex SIA may run up to 100 pages, deeply analysing long-term social impacts. The scale of complexity in accordance with the NSW SIA Guidelines is represented in the figure below:

Smaller developments, such as multi-dwelling housing projects (20-49 units), places of worship with fewer than 49 seats, or low-scale industrial and retail developments, may only need a Social Impact Comment (SIC). These comments form part of the Statement of Environmental Effects supporting the development application.
How Barr Planning Can Help
Navigating the complexities of SIAs can be challenging. At Barr Planning, we help you determine whether your project requires a basic or complex SIA or SIC. Our expertise ensures your development considers all potential social impacts, from initial scoping to final approval.
