Balconies, Decks, Patios, Pergolas, Terraces & Verandahs

It is always best to assume you need some form of approval until you can prove that you don't.

Start by confirming what zone your property is. You can find this by using the NSW Planning Portal's Spatial Viewer.

Do I need approval?

Certain minor building renovations or works are categorised as 'exempt development', meaning they do not require planning approval.

All exempt developments must still meet the National Construction Code (NCC) as well as the requirements for adjoining owners’ property rights, the applicable common law and other legislative requirements for approvals, licenses, permits and authorities.

The property must not be a heritage item or a draft heritage item, or in a foreshore area or in an environmentally sensitive area.

The State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (referred to as the 'Codes SEPP') contains specific information about balconies, decks, patios and pergolas, which can be accessed here:

The NSW Government has more information on exempt development on the NSW Planning Portal.

If the proposal doesn't qualify as exempt development, you may be able to apply through 'complying development' or a 'Development Application' (DA) – see below for more information.

Do I qualify for a complying development certificate?

A complying development certificate can be issued by council or a private certifier without the need for a full development application, providing the application meets very specific criteria.

Complying development cannot be undertaken on all land. To determine if your property meets the land-based requirements you can apply to Council for a Section 10.7 Planning Certificate.

Complying development rules are set out by Codes SEPP pt 1 div 2 s 1.17 - What development is complying development?.

All complying development must still meet the National Construction Code (NCC) as well as the requirements for adjoining owners’ property rights, the applicable common law and other legislative requirements for approvals, licenses, permits and authorities.

There are general requirements listed under Codes SEPP pt 1 - General that apply to all complying development and in addition, each type of development must also meet certain 'development standards' to be complying.

The development standards relevant to balconies, decks, patios, pergolas, terraces and verandahs are listed in the Codes SEPP which can be accessed here:

The NSW Government has more information on complying development on the NSW Planning Portal.

If the proposed development does not meet the above conditions for an exempt or complying development, you will need to seek approval by lodging a Development Application (DA).

I need a DA. What do I do?

The steps below will guide you through the process of applying for a DA.

What documents do I need?

Before you can begin the application process, there are a number of documents you will need to prepare. Some of these documents may take time to obtain or complete, so make sure you plan ahead when preparing to lodge an application.

Click on the title of each document below to learn more about what they involve, and how to prepare each of them for your application.

Please note: These are the minimum required documents for lodgement. Site constraints such as bushfire, flood, coastal erosion, heritage, etc. will require additional documentation to be supplied.

Estimated development cost

Cost estimations forecast the resources and associated costs needed to execute a development. These reports must explain the methodology used to calculate the estimate.

The value of works estimate must include the value of costs such as labour (i.e. specialist tradespeople) as well as the value of materials and fixtures to be used, as opposed to what the developer is paying for them.

For example, if labour is being provided “for free”, that labour still has a value which must be accurately included in the estimate of the value of works.

For development with a value of $0 to $150,000, a cost summary report may be prepared by the applicant or a suitably qualified person.

For development with a value of greater than $150,000 to $3 million, a cost summary report may be prepared by a suitably qualified person.

For development with a value of greater than $3 million, a detailed cost report is to be prepared by a registered quantity surveyor.

Owners consent

To lodge a Development Application (DA), you must obtain consent of the landowner, which includes the signature of every landowner.

If the owner is a company or owner's corporation, the application must be signed by a person under the common seal.

If your property is a strata unit and you are proposing development beyond your entitlement, you will need to get the approval of the owner's corporation.

If you have recently purchased the property, Council may not have received formal notice of the sale, and the former owner will be the listed on Council's records. You will need to provide Council with a copy of the transfer of sale or a letter from your solicitor advising ownership has changed.

Statement of environmental effects

The statement of environmental effects is a report that details and explains the likely impacts of the proposed development both during and after the development, and the proposed measures that will mitigate these impacts.

It also includes a detailed assessment of the proposed development having regard to all policies and planning controls that apply to the land or type of development.

The statement includes written information about proposal and any other factor of your proposal that cannot be readily shown by your plans. A high-quality statement of environmental effects is an important component to a development application.

A statement of environmental effects details the likely impacts of the proposal, and the proposed measures that will mitigate these impacts. It is a written statement about the proposal that supports your plans and drawings.

For applications that do not propose any work, such as change of use applications, a statement of environmental effects is still required. The statement must outline how the use is permissible and complies with the planning polices but also how the use will operate if consent is granted, e.g. number of staff, hours of operation, vehicular access and loading and waste management.

Please note: If a development is seeking a departure from acceptable solutions listed within the Shoalhaven Development Control Plan (DCP) 2014, a variation statement is required in accordance with Chapter 1 of the DCP.

Site plan

A plan of the site to provide the context of the proposed development.

The plan must show the exact location of buildings and other features on the site, at the same scale as the plans and elevations.

The plan must include the following details:

  • north point (true north)
  • scale (show ratio and bar scale), lot dimensions and areas

  • the location and levels of any solar panels on adjoining lots

Please ensure that your document includes the following before uploading:

  • the location, boundary dimensions, site area and north point of the land
  • existing vegetation and trees on the land

Biodiversity values threshold report

A report which assesses the biodiversity impacts of the development in accordance with the Biodiversity Assessment Method (BAM), or exceeds area clearing threshold, or the impact is considered significant after application of the 'test of significance' (a five (5) part test).

Prescribed impacts (Section 6.1 Biodiversity Conservation Regulation 2017), including the removal of non-native vegetation on the biodiversity values map, will trigger the Biodiversity Offset Scheme (BOS) and require a Biodiversity Development Assessment Report (BDAR).

The report must be prepared by an accredited assessor.

For more information, please see the Shoalhaven Development Control Plan 2014 - Chapter G5: Biodiversity Impact Assessment.

In the case of state significant development or infrastructure (SSD or SSI), the Biodiversity Conservation Act 2016 requires that an SSD or SSI application must be accompanied by a BDAR unless the Planning Agency Head and the Environment Agency Head determine that the proposed development is not likely to have any significant impact on biodiversity values, known as a BDAR waiver.

This plan will need to:

  • specify waste by type and volume and nominate reuse and recycling potential
  • nominate siting of waste storage and recycling facilities for demolition, construction and final use
  • detail how and where residual wastes will be disposed of, and
  • explain how ongoing waste management of the site will operate.
