How long do I have to respond to an IR?

The default is 6 months. Most applicants respond within 4-8 weeks because every week of IR pause is a week of holding cost.

Information Requests in Queensland DAs

Also known as: Information Request · IR · DA Information Request · RFI

An Information Request (IR) is the council's formal demand for additional information during DA assessment. Each IR cycle pauses the assessment clock and typically adds 4-12 weeks to your timeline. Avoiding IRs — or responding to them tightly — is the single biggest lever you have on approval timeline once the application is lodged.

Why IRs happen

Three common reasons. One: the application package is missing a checklist item the council needs (a stormwater plan, a traffic note, a landscape concept). Two: the technical reports aren't internally consistent (the architectural plans show one footprint, the engineering plans show another). Three: the council's specialist reviewers (engineering, environmental, transport) have a substantive question that needs a document-grade answer.

How to avoid IRs

Lodge a complete, coherent package the first time. Casa AI's document-checker can run a gap analysis on your draft submission against the council's specific checklist before lodgement — catching the missing items, the inconsistent figures, and the obvious specialist triggers.
