Development Applications

Online Development Application and Planning Related Applications Lodgement

As of 1 July 2020, all Development Applications and other planning related applications must be lodged with Hornsby Shire Council electronically via the NSW Planning Portal. This is an initiative of the Department of Planning, Industry and Environment, and they have established the Portal for lodgement of applications.

Hard-copy applications will no longer be accepted at Council’s Administration Building, either in person or via the mail. Council’s Customer Service Team will be happy to assist you in lodging your application via the NSW Planning Portal.

The NSW Planning Portal allows for a more convenient and environmentally friendly process for the lodgement of your application, allowing you to lodge online — anywhere, anytime.

You can now lodge the following Applications and Certificates through the NSW Planning Portal:

  • Development Application
  • Section 4.55 Modification Application
  • Section 8.2 Review of Determination
  • Complying Development Certificates
  • Construction Certificates
  • Occupation Certificates
  • Subdivision Certificate
  • PC Appointment
  • Subdivision Works Certificate

To Submit Online

To submit your application online you need to register for a Portal account. Once registration is complete you will be required to fill out an online application form and upload your application documentation.

Register online

It is necessary to submit the same documentation with your online application that is required by Council’s checklists and DA Submission Guideline.


If your application is complete it will be accepted for lodgement and Council’s Customer Service Team will contact you via the Portal to arrange payment of the application fees.

Payment of the invoice must be made within 48 hours of receipt otherwise the application will be cancelled.

Applications are not considered to be legally lodged with Council until the application fees have been paid in full.

Next Steps

Council’s Assessment Team will check your application to make sure that it includes everything needed in order to assess your proposal.

During the assessment of your online application, if Council requires additional information this will be communicated to you through the Portal. All additional information you provide to Council must be submitted through the Portal.

Council will also send your DA to any government agencies that require Concurrence or Integrated Development through the Portal.

After the assessment process is completed, you will be notified about your application through the Portal.

Further information on online applications is available on the NSW Planning Portal.

Do I Need to Lodge a Development Application?

Your development may not need to go through the entire development process. Some forms of low impact development do not need a Development Application and may be able to be carried out as Exempt or Complying Development.

Access to Information About Development Applications

Council has a Community Engagement Plan which, amongst other things, details the Development Application Process and the opportunities for the public to comment. The information exhibited for public comment includes the documentation submitted with an application including plans, statement of environmental effects, and any technical studies.  Decisions about public access to all other Development Application documents (including submissions and internal and external referrals) are made in accordance with relevant legislation and statutory public interest test considerations.

Construction Certificates

Before building works in relation to a DA can commence, a Construction Certificate (CC) must be applied for and issued. The assessment of the CC application may be carried out by either Council or a Private Certifier. Unlike the DA process, CC applications are not required to be advertised, or supporting documents provided for public comment whilst the CC is being assessed. Once a decision has been made, information about the CC may be requested under the Government Information (Public Access) (GIPA) Act. Provision of this information is subject to public interest test considerations.
