Development Applications

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.

How to Lodge a DA

If you are required to lodge a development application (DA), the DA must be lodged with Council before building and development works may begin. Find out about development applications here.

Follow a step-by-step guide to submitting your DA.

Access to Information About Development Applications

Council has a Community Participation Plan (CPP) which, amongst other things, details the Development Application Process and the opportunities for the public to comment (see diagram on page 8 of the CPP).  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.


Development Contributions

Council charges a contribution from developers towards the cost of providing local services and facilities that are required because of their development.
