What Requires a Development Application (DA) in NSW?

 

17th February, 2025

 

Building or renovating your property can be an exciting yet overwhelming experience. If you’re in New South Wales (NSW) and planning any development, it’s crucial to understand that not all construction activities are exempt from a Development Application (DA). While most people know that constructing a house requires a DA, there are other common projects that also need approval. In this blog, we’ll outline various instances where a DA is necessary beyond just building a house.

What is a Development Application?

A Development Application (DA) is an official request to your local council for approval to carry out certain construction work. It ensures the proposed development complies with zoning laws, environmental regulations, and other local council policies. A DA outlines all aspects of your project, including design, materials, and construction methods. It’s essential to obtain this approval before beginning most types of development in NSW.

When Do You Need a DA Beyond Building a House?

Elevated Water Tanks

If you’re planning to install a water tank on your property, it’s important to know that certain types may require a DA. Elevated water tank often need approval, especially if they are large or tall. Councils will assess the potential impact on surrounding views, privacy, and aesthetics. Be sure to check the height and location restrictions in your local council area before proceeding with installation.

Sheds and Other Outbuildings

A shed may seem like a simple addition to your property, but if it exceeds a certain size, it will likely require a DA. In most councils, sheds larger than 20-25 square metres require approval. These structures can impact the environment, neighbouring properties, or the local streetscape, making a DA necessary to ensure proper placement and compliance with zoning laws.

Swimming Pools

If you’re planning to install a swimming pool, it’s important to know that a DA may be required, especially for larger pools or if your property is in a heritage or environmentally sensitive area. Pool fences, drainage, and safety measures are some of the considerations local councils will evaluate when reviewing your application.

Renovations and Extensions

Significant home renovations and extensions also require a DA, especially if they alter the external appearance or increase the floor space of the building. For instance, adding a second storey or extending your living areas into the backyard might change the property’s footprint and may require approval.

Driveways and Crossings

If you plan to build a new driveway or alter an existing one, particularly for properties on busy streets or near sensitive zones, a DA may be necessary. This is to ensure the driveway complies with traffic, safety, and accessibility standards.

Change of Use of Land or Buildings

If you intend to change the use of a building or land—such as converting a residential property into a commercial one—a DA will be required. This ensures that the new use complies with local zoning and won’t cause adverse impacts on the neighbourhood.

 

Why a DA Matters

Obtaining a DA ensures that your development complies with local planning laws, avoids potential disputes with neighbours, and ultimately protects your investment. While some projects can be approved under a Complying Development Certificate (CDC), which is a faster process, many developments still require a DA. A DA provides a merit-based evaluation, meaning it considers the individual merits of your specific project.
