Development Application (DA) Process

These pages provide a summary of the development process at Willoughby City Council. Council wishes to inform residents and any other interested persons about the steps in the process and, particularly, how and when they can be involved.

Extended Notification Period - December 2016 and January 2017

Notification letters advising neighbours of applications received by Council will continue to be sent out during December 2016 and January 2017, however:


The period between Monday, 19 December 2016 and Friday, 13 January 2017 inclusive will be excluded from the notification period.

This means that the notification will be extended for the relevant number of days that fall within the period of Monday, 19 December 2016 to Friday, 13 January 2017.



  1. DAs notified outside 19/12/16-13/1/2017
    e.g. a DA placed on notification on 14/12/2016 (the notification letter date) will stay on notification until 23/1/2017.
  2. DAs notified between 19/12/2016-13/1/2017 inclusive
    e.g. a DA placed on notification on 29/12/2016 (the notification letter date) will stay on notification until 30/1/2017.
