Development Application Guide
If you are proposing any development or building works in Mosman there are a number of steps you must take.
Before you undertake any development or building works, you will need to determine what approvals are required.
The Environmental Planning and Assessment Act 1979 defines development as:
- the use of land, and
- the subdivision of land, and
- the erection of a building, and
- the carrying out of a work, and
- the demolition of a building or work
- any other act, matter or thing controlled by an environmental planning instrument.
Certain types of minor development may be carried out as Exempt or Complying Development. All other development will require a Development Application to be submitted to Council.
A number of minor types of low impact works or renovations may be exempt development. Council approval is not needed if your project meets specific development standards. The standards you must comply with for most exempt development works are in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008.
If any of the criteria cannot be fully met, a complying certificate or development approval must be obtained before carrying out the work or development.
Some common examples of exempt development are:
- Awnings and other shade structures
- Garden sheds
- Home business
- Air conditioning units
Visit the NSW Planning Portal or contact Council‘s Planning Advisor on 9978 4172 for further information on Exempt Development.
Complying Development is a combined planning and construction approval for straightforward development that can be determined through a fast-track assessment by a council or an accredited certifier. Providing your application meets specific development standards, approval (known as a Complying Development Certificate or CDC) can be granted, without the need for a full Development Application.
Complying development may include:
- Internal alterations to a house
- Swimming pool
- Carports, garages and driveways
Visit the NSW Planning Portal or contact Council‘s Planning Advisor on 9978 4172 for further information on Complying Development.
If your proposal does not meet the Exempt or Complying Development criteria, then provided the development is permitted with development consent you will need to lodge a development application. Proceed to the next step.
There are several things you should do prior to lodging your development application:
- Establish what is permissible on your property, what potential constraints affect your property and what planning controls apply to the proposed development, in particular the Local Environmental Plan and Development Control Plans.
- Talk to your neighbours to assist them to understand your proposal. Consulting neighbours can improve the development application process if neighbours have an understanding of the proposal before the development application is lodged. You may be able to resolve an issue your neighbour has before lodging your development application.
- Review the Application Lodgement Guide and Matrix. The Application Lodgement Guide and Matrix provides important information for applicants when lodging applications with Mosman Council and outlines the different lodgement requirements for development applications, modification applications and review applications.
- Meet with Council officers and discuss the proposal. This will provide opportunity to seek input from council officers about your proposal before preparing detailed plans. Meetings with Council officers can take one of two forms:
Informal meetings can provide a general indication as to whether the proposal meets the objectives of the planning controls in Mosman, and can identify issues that need to be addressed in the development application. No written feedback will be provided.
Formal pre-lodgement meeting
A formal pre-lodgement meeting with council officers will be documented and written feedback on your proposal will be provided.
What can I expect from a formal pre-lodgement meeting?
- an understanding of the permissibility of the proposal and the relevant development standards, controls and policies;
- an understanding of issues that might cause delay, need further consideration, have some sensitivity or cause concern;
- an understanding of the documentation required for lodgement;
- a meeting with at least two assessment officers;
- a meeting date arranged within ten (10) days after lodgement; and
- written feedback outlining the description of site and proposal discussed as well as an outline of any issues or concerns raised by the proposal.
- If you decide to go ahead and lodge your application, the pre-lodgement meeting minutes will be reviewed as part of the assessment process.
The amount of feedback given depends on the amount and quality of information that you are able to provide. Useful material includes:
- concept plans and survey plan;
- general information covering what you hope to achieve on the site and how you propose to address any likely impacts on the local area; and
- details about the site and adjoining development.
Attending a pre-lodgement meeting and addressing concerns and comments made does not imply that the development will gain development consent. The views of the community, internal specialists and other government authorities are not able to be taken into account in the pre-lodgement process.
How do I arrange a formal pre-lodgement meeting?
- Complete the Application Lodgement Guide and Matrix, attach relevant documentation
- Pay the relevant application fee based on the estimated cost of the proposal.
- Lodge the application in person at Council or by mail.
The pre-lodgement application will be allocated to an officer who will call you to arrange a site inspection and meeting time.
The following charges apply to formal prelodgement meetings:
|Cost of Work||Fee|
|Up to $1,200,000||$1,248.50|
|$1,200,001 to $2,500,000||$2,076|
|$2,500,001 to $5,000,000||$3,122|
All development applications, modification applications and review applications are required to be submitted online via the NSW Planning Portal.
This follows a mandate by the NSW Government for Councils to use the NSW Planning Portal.
How to lodge your application on the NSW Planning Portal
Review the Application Lodgement Guide and Matrix:
The Application Lodgement Guide and Matrix provides important information for applicants when lodging applications with Mosman Council and outlines the different lodgement requirements for development applications, modification applications and review applications. Council’s form DA Checklist and Applicant Declaration is required to be submitted with all development applications.
Register or Login:
Enter your development proposal and application details:
Enter the application details in the portal using the Submit a Development Application Online guide and upload all required documents as separate files. The required documents are detailed within the DA Checklist and Applicant Declaration.
Once an application is submitted through the NSW Planning Portal, Council will undertake a review of the application. Council will make a decision to accept the application, request additional information or return the application. Should additional information be required, you will receive an email via the NSW Planning Portal outlining the required information.
If the application documentation is found to be in order, Council will calculate and advise the applicant via email of the required fee and the application reference number. The fee can be paid in person at Council, by mail or by online payment. On payment of the fee, the application will be formally lodged, a tax invoice/receipt will be emailed to the applicant, and the assessment of the application will commence. The application can then be tracked on Council’s DA Tracker, where the name and phone number of the assessment officer will be available.

How do I relodge my returned application?
For DAs which have been returned to the applicant due to insufficient information, the Planning Portal provides the option to create a copy of your DA allowing you to relodge a new application including the additional documentation with ease.
My property address is not appearing in the Planning Portal?
If you have entered your address in the search box and it is not appearing, select the tick box next to ‘Address did not display?’ and re-type your address then select next and it should appear.
I don‘t have access to a personal computer, where can I lodge my application?
Council‘s library offers free computer services for the community. Find more information on Council‘s library services and opening hours here.
Applications are notified in accordance with the Mosman Community Participation Plan.
The majority of applications are notified for 14 days. Applications involving Nominated Integrated development and/or Designated development are notified for 28 days. Extended notification periods apply over the Christmas and New Year period.
Applications are notified in the following ways:
- a letter describing the proposal is sent to affected neighbours.
- a notice is erected on the site.
- the proposal is listed on Council’s Applications Received and Determined page on this website.
During the notification period the DA Tracker contains all relevant details of the proposal, including plans to assist you in making a submission.
If you make a submission please remember:
- You should review the plans and read the accompanying information so you are clear on the details. Mostly, the applicant will be your neighbour or their architect so you may be able to clarify detail or resolve any concerns by discussing it with them.
- Development assessment involves a process of mutual adjustment between your legitimate concerns and the reasonable development rights of the applicant. Council has to evaluate both within a statutory planning framework and in many cases no party will be totally satisfied. This is the nature of the process.
- Council is interested in what your issues are with the DA. These are best expressed in your own words and need not rely on lengthy references to provisions of planning instruments (LEPs and DCPs) – references which may obscure real issues.
- Council staff are available to assist you with interpretation of DA documents and general enquiries during the notification period; however, detailed explanation of the applicant’s intent can best be obtained from the applicant direct.
- Staff do not reply to questions posed in written submissions but cover issues as part of the DA assessment.
How to make a submission
During the notification period you are able to make a submission either online via the DA Tracker or by email to firstname.lastname@example.org.
Submissions will be acknowledged by email or letter by post.
The supply of personal contact information in a submission is voluntary pursuant to the Privacy and Personal Information Protection Act 1998. By including your contact information in a submission you are acknowledging that it will be made available for public view at Council offices and through the Council website.
If you have given a gift or made a donation to a Councillor, an employee or an approved contractor of Mosman Council within the past two (2) years, by law you must include a disclosure statement with your submission.
Assessment and Decisions
When considering a DA the assessment officer will have regard to:
- Statutory requirements under the Act;
- Adopted policies of Council; and
- Issues raised in written submissions.
Some applications are determined under delegated authority of Council whilst others are determined by the Mosman Local Planning Panel (MLPP) or the Sydney North Planning Panel.
If the application is to be referred to the MLPP for determination you will not be notified in writing. Instead, you are invited to either:
- Register for MLPP Notification on the DA Tracker and receive emailed notification if an application is referred to MLPP for determination; or
- Check Council website‘s Mosman Local Planning Panel page.
When a final determination is made all people who made a submission are informed of the outcome. The Assessment Report and Notice of Determination are made available on the DA Tracker.
Note: any written submission made regarding a Development Application will be available for the public to access via the DA Tracker.
The majority of Development Applications lodged are determined by Council staff. Applications will be referred to the Mosman Local Planning Panel or the Sydney North Planning Panel for determination where they meet the criteria outlined below.
Mosman Local Planning Panel
Applications will be referred to the Mosman Local Planning Panel for advice prior to determination if:

Further information regarding the Mosman Local Planning Panel, including the agenda and decisions can be found here.
Sydney North Planning Panel
If the capital investment value of a DA is over $30 million and/or it has regional significance it will be referred by Council to the Sydney North Planning Panel for determination. The NSW Planning Portal provides further information relating to the Sydney North Planning Panel..
Public notification of certain decisions and reasons for the decisions
Schedule 1 of the Environmental Planning and Assessment Act 1979 provides mandatory notification requirements relating to determinations of an application for development consent or modification of a development consent and requires that public notification be provided of:
a. the decision, and
b. the date of the decision, and
c. the reasons for the decision (having regard to any statutory requirements applying to the decision), and
d. how community views were taken into account in making the decision.
This information is provided on the DA Tracker in the form of the Notice of Determination (a & b) and Assessment Report (c & d).
Once your DA is approved, there are some more steps you must take before you can start to build:
a. Obtain a Construction Certificate (CC)
You need a construction certificate before you can start building work.
A construction certificate confirms building plans comply with the BCA, are ‘not inconsistent’ with the development consent and comply with relevant conditions of the development consent.
Private accredited certifiers and councils can issue construction certificates.
If you want Council to issue your construction certificate you will need to complete the Application for Construction Certificate. Council‘s certifiers can be contacted on 9978 4094 should you have any questions or require further information about lodging a construction certificate.
The NSW Department of Fair Trading provides a register of certifiers and information on what to check before appointing a certifier here.
The NSW Planning Portal also provides information regarding Construction certificates here.
Before obtaining a construction certificate with either a private accredited certifier or council you will need to pay certain fees to council. Using the booking calendar on Council’s website an appointment can now be made to pay these fees with customer service staff. Customers booking an appointment will benefit from reduced waiting time and they will also receive an email reminder of all documents required for the appointment.
Where a condition of consent requires the creation of an easement, covenant or restriction on title, it is recommended that you seek legal support to prepare the documentation for Council to sign. A fee applies for the checking, approval and execution of the restriction on the use of land by Council and must accompany the restriction on the use of land when lodged with Council. Once submitted it usually takes one week for the documentation to be signed and to become available for collection. Where the terms differ from those provided by Council in the Development Consent, the process may take considerably longer as Council will need to have the proposed terms reviewed by its lawyers.
b. Appoint a Principal Certifying Authority (PCA)
The PCA must be appointed by the ‘person having the benefit of the development consent’ – this means you as the owner and not your builder.
The PCA can either be council or a private certifier.
If you want to appoint Council as the PCA please contact our certifiers on 9978 4094.
The NSW Department of Fair Trading provides a register of certifiers and information on what to check before appointing a certifier here.
The PCA is usually the same person or firm that issued your CC, but does not have to be – as with your CC, it can be a private accredited certifier or council as PCA.
The PCA’s job is to work with you through the construction process and issue you with an Occupation Certificate (OC) when the work is completed. To make this decision, the PCA inspects the development at various points in the build and ultimately ensures that the building is safe and fit to occupy and in accordance with the development consent and CC.
c. Give the council two days’ notice before you start work
As the person having the benefit of a development consent, you must give council at least two days’ notice in writing of your intention to commence work on the site, and must notify council in writing at least two days before building work commences of your appointed PCA.
A Principal Certifying Authority (PCA) is required to inspect the building work during the course of construction to ensure compliance with the relevant standards. This PCA may be the Council or from private enterprise. Council must be notified who the PCA is at least 2 days before work commences.
