Northern Beaches Council Requirements for Building in Collaroy Beach

 

  • Zoning types

    • Primarily R2 Low Density Residential and R3 Medium Density near main roads

    • Environmental overlays on foreshore and dune areas

  • Setbacks

    • Front: 6–8 m, with variations for coastal protection zones

    • Side: 900 mm–1.5 m depending on lot width and building height

    • Rear: Varies — beachfront lots may have foreshore building lines that reduce usable space

  • Typical lot sizes

    • From 500 sqm in central residential streets to over 1,200 sqm for larger beachfront parcels

  • Key constraints

    • Coastal Erosion Hazard mapping applies to some foreshore blocks

    • BAL-12.5 to BAL-29 near dune vegetation

    • Sand dune stability and retaining structures must meet geotechnical standards

    • Height restrictions preserve neighbouring views and sunlight access

  • Utilities available

    • Fully serviced with water, sewer, power, gas, and NBN

    • Stormwater design often critical due to sandy soils

Building in Collaroy Beach requires compliance with coastal hazard guidelines, view-sharing controls, and environmental sustainability measures set by Northern Beaches Council.

DA vs CDC: What’s Right for Your Collaroy Beach Project?

In Collaroy Beach, coastal regulations often make Development Applications (DA) the preferred route. Whether it’s a Development Application (DA) or a Complying Development Certificate (CDC), we’ll guide you through the process from start to finish.

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

DA (Development Application):

  • Suited for beachfront builds, coastal hazard areas, or environmentally sensitive sites

  • We coordinate all consultants, reports, and council interactions

CDC (Complying Development Certificate):

  • Appropriate for straightforward additions or compliant new builds away from the foreshore

  • We’ll evaluate your site and suggest the quickest approval path

FAQs About Building Design in Collaroy Beach

  • Only if you meet foreshore setback requirements and coastal hazard guidelines — we help maximise your position within those limits.

  • We use durable cladding, corrosion-resistant fixtures, and layouts that buffer strong winds while capturing views.

  • In many cases, yes — particularly for beachfront or dune-adjacent builds. We arrange the right professionals for your project.

  • Not at all! While we love working in spots like Avalon, Narrabeen, and Dee Why, we also take on projects across the North Shore, Ku-ring-gai, and even further out. We’re open to select builds up to 4 hours from the Northern Beaches Council area.
