🏡 WHAT IS A DEVELOPMENT APPLICATION?
Following on from our posts about Planning Approval and Building Permits, today we’re looking at another term you may come across when planning a project — a Development Application (DA).
A Development Application is generally used to seek approval for a proposed development or change of use of a property where planning approval is required.
Depending on the project, a DA may involve the Shire assessing things such as:
🔹 The proposed use of the property
🔹 Site layout and setbacks
🔹 Building height and scale
🔹 Parking and access
🔹 The impact on neighbouring properties
🔹 Landscaping and streetscape
🔹 Local planning requirements and policies
A DA is not the same as a Building Permit.
Put simply:
Planning approval looks at whether the proposed development is acceptable from a planning perspective.
A Building Permit deals with whether the building work can legally be constructed and meets the applicable building requirements.
Every project is different, and not every job will require a Development Application.
At W. Gibbs & Son, we can help you understand the approval pathway for your proposed project and work with the relevant designers, consultants and certifiers to help get things moving.
📍 Before you start building, make sure you know what approvals you need.
