Development applications, often shortened to DAs, generate strong feelings. They also generate a lot of confusion, because the process is not as simple as approval or refusal.

A DA is a request to a council, or sometimes to a state-level body, to do something with a site. It goes through assessment against planning rules, often through a public notification period, and sometimes through independent panels.

Many DAs are modified along the way. Some are withdrawn. Some are refused and resubmitted. The outcome that ends up on a street can look quite different from the first lodgement.

We will cover DAs in plain language: what is proposed, what stage it is at, and what the realistic range of outcomes looks like, rather than treating every lodgement as a finished project.

From the desk. Sydney and Surrounds is a practical local newsroom for Greater Sydney. If there is something in your suburb that deserves more attention, we would like to hear about it.
