If you’re planning to build or renovate a house in Perth or anywhere in Western Australia, chances are you’ve heard the term “Development Application” (DA). But what exactly does it mean, and why is it important?
In this article, we’ll explain what a Development Application is, why it’s essential, and how Perth Drafting can help guide you through the process to bring your vision to life.
What Is a Development Application (DA)?
A Development Application is a formal request for planning approval from your local council or relevant planning authority. It outlines your proposed project whether it’s building a new house, adding a second storey, subdividing land, or making major renovations.
The DA ensures your plans comply with local zoning regulations, building codes, design guidelines, and environmental considerations.
When Do You Need a Development Application?
You’ll likely need a DA if your project involves:
- Building a new home
- Adding an extension or second storey
- Developing a granny flat or ancillary dwelling
- Subdividing a block of land
- Constructing a multi-unit development
- Making significant changes to the external appearance of a building
Even some internal renovations might require approval if they impact the building’s structure or use.
Tip: Always check with your local council or speak to drafting professionals like us before starting your project.
Perth Development Application Requirements
In Perth and across Western Australia, DAs must comply with policies like the Residential Design Codes (R-Codes) and your local Local Planning Scheme (LPS).
Common DA requirements include:
- Site plans and floorplans
- Elevations and streetscape views
- Shadow diagrams
- Design statements
- Lot boundary setbacks and open space calculations
Different councils may also require bushfire assessments, heritage reports, or stormwater management plans depending on your location.
How Long Does the DA Process Take?
The time frame can vary based on the complexity of the proposal and your local council’s processing times. On average:
- 60 to 90 days
