cancel old building application

Not sure about Brisbane council but my council I had to cancel a older da which I had no knowledge of from the previous owners and all I had to do was write a email stating that I was the current owner and that I retract all previous development application prior to the date that I purchased the property.

Thanks for the response! However, it has been sorted. But for others benefit here is what we had to do.

Unfortunately, it's not straightforward. BCC washed their hands off saying they can't cancel without the certifier cancelling it (as they lodged it on behalf of the builder whom we engaged & paid). Certifier gets business from the builder and didn't oblige to cancel but directed us to the builder who held us ransom until we paid them what they wanted. It was a very stressful period of our life. The system is so flawed that being the owner you don't have any right once you engage a builder even though you don't proceed to the contract with the builder.
Tip to future myself. Lodge the application without the builder and engage them to just build the house. Hope it helps someone!
