The complete guide to development applications in Brisbane (2026)

A development application (DA) in Brisbane is a formal request to Brisbane City Council for permission to carry out development that the planning scheme does not allow as of right. Most of them succeed: Casa Intelligence analysis of 149,392 decided Brisbane applications shows 95.7% ended in approval, with a median of 52 days from lodgement to decision. But the headline numbers hide enormous variation — a straightforward subdivision and a six-storey apartment building move through the same legal framework at completely different speeds, costs, and risk levels. This guide walks through the whole process: the pathways, the realistic timelines, the fees, information requests, and what happens if council says no.

Brisbane DAs in 2026: the key numbers

Approval rate. 95.7% of the 149,392 decided Brisbane applications in the Casa Intelligence dataset were approved. Refusal is the exception, not the rule — but withdrawals and heavily conditioned approvals do the quiet damage.

Median time to decision. 52 days across all decided applications; 62 days for the 20,884 applications decided since January 2023. These are elapsed calendar days from lodgement to decision, including time the statutory clock was stopped.

Multiple dwelling projects. 8,258 decided; 93.8% approved; median 144 days. Across the 764 decided since 2023, the approval rate was 93.5% and the median was 125 days.

Subdivision (reconfiguring a lot). 16,593 decided; 96.8% approved; median 55 days.

Dual occupancy. 184 decided; 91.8% approved; median 113 days.

The statutory benchmark. Under the Planning Act 2016 DA Rules, the core decision period is 35 business days for a code assessable application with no referrals. Real elapsed times run longer mainly because information requests stop the clock.

All figures are Casa Intelligence analysis of Brisbane City Council application records. Past decisions do not guarantee future outcomes, and figures reflect our dataset, not an official council statistic.

What actually is a development application, and when do you need one?

You need a DA when your proposal is categorised as assessable development under the Brisbane City Plan 2014 or the Queensland Planning Regulation 2017 — broadly, anything the scheme does not accept outright. If your proposal is accepted development and meets the acceptable outcomes, you do not need a DA at all.

The main types of development you might apply for are a material change of use (using land differently — for example, turning a house lot into townhouses), reconfiguring a lot (subdividing, amalgamating, or rearranging boundaries), building work, and operational work (earthworks, civil works, landscaping). A single project often needs more than one: a townhouse development is typically a material change of use followed by operational works, and sometimes a reconfiguration if the units will be individually titled.

The first question for any site is therefore not "will council approve it?" but "what category of assessment does my proposal trigger?" — because that determines everything downstream.

Will your application be code assessed or impact assessed?

Code assessment means council assesses your application against the relevant codes only, with no public notification and no third-party submissions. Impact assessment adds public notification, submissions from anyone who objects, broader council discretion, and submitter appeal rights.

The pathway is set by the tables of assessment in the Brisbane City Plan 2014 — zone by zone, use by use. The same proposal can be code assessable on one street and impact assessable two blocks away because the zone or a neighbourhood plan changes. Getting this wrong at the site-selection stage is one of the most expensive mistakes in the process, because impact assessment adds months of time, tens of thousands in cost, and genuine uncertainty. We cover the mechanics in detail in our guide to code vs impact assessment in Queensland.

A practical signal from the data: Brisbane subdivision applications — which are predominantly code assessable — show a median of 55 days to decision, while multiple dwelling applications, which are larger and more frequently contested or complex, show a median of 144 days. That is not a controlled comparison of pathways, but it is a fair picture of how the easy end and the hard end of the Brisbane system behave.

How long does a Brisbane DA actually take?

For a clean code assessable application, a realistic expectation in 2026 is two to four months lodgement-to-decision; for a multiple dwelling project, the median is around four months and slower cases run well beyond that. The statutory process under the DA Rules looks like this: council confirms a properly made application within 10 business days; it may then issue one information request, which stops the assessment clock; you have up to 3 months to respond; impact assessable applications add a public notification period of at least 15 business days; any state referral through SARA (for example a state-controlled road or koala habitat) runs up to 35 business days; and the decision period itself is 35 business days for code assessment without referrals.

Stack those perfectly and a code assessable DA could be decided inside two months. The Brisbane-wide median of 62 days since 2023 says plenty of simple applications do roughly that. The 125-day recent median for multiple dwelling projects says complex ones do not — the difference is mostly information requests and redesign cycles, not council sitting on files.

One important caveat on our figures: we measure elapsed calendar days from lodgement to decision. Council reports its own performance in statutory business days with the clock stopped during information requests, so official figures will always look faster than the elapsed time you actually experience. For project planning and holding-cost modelling, elapsed time is the number that matters.

What does a Brisbane DA cost?

Council application fees are set in Brisbane City Council's fees and charges schedule, revised each July, and scale with the type and size of the development — check the current schedule for your specific use rather than budgeting from a generic figure. The fees are genuinely the small end of the cost stack.

The larger items are the application documents and the infrastructure charges. A complete DA package for a multi-dwelling project — town planning report, architectural drawings, engineering, stormwater, landscape and any overlay-triggered specialist reports — typically runs $30,000 to $80,000 in consultant fees. Infrastructure charges are capped by the State Planning Regulation 2017 at $36,670.70 per three-or-more-bedroom dwelling or lot, and $26,193.40 per one-or-two-bedroom dwelling (2025–26 indexed amounts), with a credit for the existing lawful use of the site. On a six-townhouse project replacing one house, the charges alone can exceed the entire consultant budget.

We break the whole stack down — fees, consultants discipline by discipline, charges, and the hidden items — in what a development application really costs in South East Queensland.

What is an information request, and how do you avoid one?

An information request (RFI) is council's formal notice that it needs more before it can assess your application — and it is the single biggest cause of DA timeline blowouts. The clock stops when the RFI issues and does not restart until you respond, and under the DA Rules you have up to 3 months to do so. One RFI cycle routinely adds two to four months of elapsed time plus the consultant fees to produce whatever was asked for: a stormwater management plan, a traffic assessment, design amendments against a specific code provision.

Council may only issue one information request, which cuts both ways: you will not be drip-fed questions forever, but the one request can be long. The gap between Brisbane's 35-business-day statutory decision period and the observed 62-day recent median is substantially explained by RFI cycles.

Avoiding one is unglamorous: lodge complete. Identify every applicable code and overlay before lodgement, respond to each assessment benchmark in the town planning report, and include the specialist reports the overlays predictably trigger. Applications prepared reactively — lodge first, see what council says — pay for that strategy in months.

What happens if council refuses, or approves with conditions you cannot live with?

You have appeal rights. Under the Planning Act 2016, an applicant may appeal a refusal, or conditions of an approval, to the Planning and Environment Court within 20 business days of the decision notice. In practice most disputes never reach a hearing — the appeal period is also the window for negotiation, and councils routinely agree to a negotiated decision notice that softens problem conditions. There is also a formal change representation process after approval for tweaking conditions without a full appeal.

Two things are worth knowing before you rely on the court as a backstop. First, appeals are slow and expensive — legal and expert costs typically dwarf the original application costs, so an appeal only makes commercial sense on projects with real value at stake. Second, for impact assessable applications, submitters who made a properly made submission get appeal rights too — meaning even an approval can be dragged into court by objectors. That risk simply does not exist for code assessable development, which is a major reason the pathway question matters so much.

Given 95.7% of decided Brisbane applications are approved, the practical risk for most applicants is not refusal — it is time, cost, and conditions. Read approvals in our comparable-DA data and you will see the pattern: council rarely says no, but it frequently says "yes, if".

How do you stack the odds before you buy or lodge?

The applications that move fastest share a boring secret: the work was done before lodgement. That means confirming the zone and assessment pathway from the actual tables of assessment, mapping every overlay, checking what council approved on comparable sites nearby — yield, conditions, timeframes — and scoping the specialist reports upfront rather than waiting for the RFI to reveal them.

This is exactly what a $150 Preliminary Planning Report does for any Brisbane address: zoning, overlays, the likely assessment pathway, approval likelihood based on comparable decided DAs, and the consultant disciplines your site will need — prepared by a qualified development professional (Master of Architecture) and delivered in minutes. You can also browse suburb-level DA statistics to see how your patch of Brisbane behaves.

Caveats worth taking seriously

Our statistics describe what Brisbane City Council has decided historically; they are not a prediction for your site, and no one can guarantee an approval. Application records vary in quality, our dataset does not capture every application ever lodged, and elapsed-time medians include clock-stopped periods. Planning schemes are amended regularly — always verify against the current Brisbane City Plan 2014 provisions before committing money. And none of this is legal advice; for contested or high-stakes applications, engage a planning lawyer.

Where to start

If you are weighing up a Brisbane site — to buy, to develop, or just to understand what is possible — start with the data rather than the guesswork. A $150 Preliminary Planning Report gives you the zoning, overlays, assessment pathway, comparable decided DAs and approval likelihood for any address, in minutes. If you decide to proceed, our $1,999 DA Project service has a qualified development professional (Master of Architecture) prepare, review, and lodge your application with council, coordinating the specialist consultants your site requires.
