About
There are strict guidelines, legislation and approval processes that apply to construction works on private property. If you witness a breach of these regulations, you can request Council to investigate. These include:
- Construction works outside approved hours
- Mud or soil from the building site on the road
- Onsite building works or consent breaches:
- Physical building works
- Non-compliant landscaping
- Inadequate tree protection
- Inadequate erosion and sediment control
- Excessive noise on the building site
More information
Before lodging a request, check Council's website to confirm there is an active consent and what works are approved. Council's DA Tracking service will show applications lodged for properties in Ku-ring-gai including Development Applications (DAs), Complying Development Certificates (CDCs) and Construction Certificates (CCs).
You can view DA plans through this service. To view CC and CDC plans and documents, you will need to submit an informal access to information request once you have a reference number.
You can find more information on Council's website using the following links:
- If you notice non-compliance related to land use outside of construction works, submit a request under Unauthorised land use
- If the works you have witnessed appear to be constructed without any of the required building approvals, submit a request under Illegal building works/construction
Submit a request
Where possible, before lodging a complaint, speak with the property owner and politely explain the issue. If this is not possible, or the issue is not resolved, use the link below to request a Council investigation.
Please note: You are encouraged to provide your contact details in case we require further information in relation to your request. In some cases, if we have insufficient information, we will not be able to investigate.
Thank you for providing feedback.
