The Hornsby Shire Council Requirements for Building in Bobbin Head

  • General Setbacks:

    • Strict setbacks apply due to environmental protection zones, waterways, and vegetation buffers

  • Floor Space Ratio (FSR):

    • Typically limited to maintain low site coverage—often under 0.3:1

  • Average Block Size:

    • Rare, bespoke properties—usually sloping, vegetated, or water-adjacent

  • Zoning:

    • E2 Environmental Conservation, E4 Environmental Living, or adjacent to RU2 and National Park boundaries

  • Local Considerations:

    • Proximity to national park, bushfire risks (often BAL 40 or FZ), flora/fauna protection, limited vehicular access, and marina/waterway proximity

Building in Bobbin Head requires careful consideration of zoning overlays, bushfire ratings, and environmental planning policies.

DA vs CDC: What’s Right for Your Bobbin Head Project?

Due to the highly sensitive zoning and location near protected land, Development Applications (DAs) are typically required.

Here’s a quick breakdown to help you understand the difference:

DA (Development Application):

  • Required for all major building work, new dwellings, or structural changes

  • Lodged with Hornsby Shire Council

  • Environmental impact reports and BAL assessments are almost always needed

  • Public exhibition or referral to National Parks may apply

CDC (Complying Development Certificate):

  • Rarely applicable due to zoning and heritage constraints

  • May apply for select internal works or very minor additions on compliant sites

We’ll evaluate your site and guide you to the most fitting approval pathway.
