What a development application really costs in South East Queensland (2026)

A development application in South East Queensland rarely costs what the council fee schedule suggests. For a small residential project — a dual occupancy, a two-lot subdivision — a realistic all-in figure is $30,000 to $80,000 once consultants and infrastructure charges are counted. For a multi-dwelling project, the application documents alone typically run $30,000 to $80,000, and infrastructure charges — capped by the State at $36,670.70 per three-or-more-bedroom dwelling or lot (2025–26) — are usually the single biggest line. This guide breaks the full cost stack down, item by item, with the data on where budgets actually blow out.

The DA cost stack at a glance

Council application fees. The smallest layer. Set per council, per use, per scale, and revised annually each July — typically thousands, not tens of thousands.

Consultant fees. The layer people underestimate by discipline count, not by rate. A town planning report, drawings, and two or three overlay-triggered specialist reports add up fast.

Infrastructure charges. The biggest single line on most multi-dwelling and subdivision projects. Statutory maximums: $36,670.70 per 3+ bedroom dwelling or lot, $26,193.40 per 1–2 bedroom dwelling (State Planning Regulation 2017, 2025–26 indexed).

The hidden layer. Information request responses, redesign cycles, and holding costs while the application sits with council — median decision times in our data range from 28 days in Logan to 52 days in Brisbane, and multi-dwelling projects run far longer.

Figures below are Casa Intelligence analysis of council DA records plus statutory schedules. Every project differs; treat these as calibration, not a quote.

What are the council application fees?

Council fees are the cheapest and most predictable part of the stack. Each SEQ council publishes its own fees and charges schedule, and fees scale with the type of application and the number of dwellings or lots. For a typical multi-dwelling residential application on the Sunshine Coast, expect $8,000 to $20,000 in council application fees; simple single-dwelling or dual occupancy applications sit well below that. Because schedules are revised every July, quote the current year's schedule in your feasibility rather than a figure from a blog post — including this one.

The mistake is not misjudging the fee; it is treating the fee as the cost of the DA. It is closer to 5–15% of it.

What do the consultants cost, discipline by discipline?

For feasibility purposes in 2026, the working ranges we see across SEQ are: town planning report and DA management, $8,000 to $15,000; architectural concept and DA drawings, $15,000 to $30,000; quantity surveyor or cost consultant, $5,000 to $12,000. A complete lodgement package for a multi-dwelling project — planning report, architecture, civil and stormwater engineering, landscape plan, plus specialist reports — totals $30,000 to $80,000 depending on the site.

The variable is the specialist layer, and it is driven almost entirely by overlays and referrals rather than by project size. The disciplines that appear on SEQ decision notices and application packages include: cadastral surveyor, stormwater/hydraulics engineer, traffic engineer, bushfire consultant, flood/hydrology consultant, acoustic consultant, ecologist, geotechnical engineer, landscape architect, heritage consultant, and contaminated-land consultant. Each one you trigger adds roughly $3,000 to $15,000 for reports at DA stage — and a site with three overlays can trigger three of them before you have drawn a floor plan.

This is why two projects of identical size can have wildly different DA budgets. The cost driver is the site, not the building. Knowing your required disciplines before you commit to a site — not after the information request tells you — is one of the highest-value pieces of information in the entire process. It is a core output of our $150 Preliminary Planning Report, which identifies the overlays on any SEQ address and the consultant disciplines they trigger, in minutes.

What are infrastructure charges, and why are they the biggest line?

Infrastructure charges are levies councils apply to development to fund trunk infrastructure — transport, water, sewer, stormwater, parks. They are calculated per dwelling or per lot, payable when the development proceeds, and they are not negotiable in the ordinary course.

The State Planning Regulation 2017 caps adopted charges 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), and several SEQ councils adopt residential charges at or near those maximums. On the Sunshine Coast, charges for a new dwelling typically run $28,000 to $35,000. You receive a credit for the existing lawful use — demolish one house to build six townhouses and you pay charges on the net five additional dwellings.

Run that example: five net three-bedroom townhouses at charges near the cap is in the order of $180,000 — before construction, and typically payable in full. On most SEQ multi-dwelling feasibilities this is the largest single statutory cost, and it is the item most often missing or underweighted in back-of-envelope numbers. Each council's adopted charges resolution is public; use the actual resolution for your council and product type, and confirm the bedroom-count boundary, because a two-bed-plus-study can be assessed as a three-bed.

How does the assessment pathway change the cost?

Impact assessment costs more than code assessment — reliably. Public notification adds direct costs (signage, notices) and, more importantly, it adds submitters. Responding to submissions means consultant time; a contested approval can then be appealed by submitters, and Planning and Environment Court proceedings involve legal and expert costs that typically exceed the entire original application budget. Code assessable applications carry none of that exposure: no notification, no submitter appeals.

The pathway also moves the timeline, which is itself a cost (next section). If a site offers you a code assessable design option — for example, staying under a height or density trigger that would tip the application into impact assessment — that option is often worth more than the extra yield it gives up. The mechanics of what puts you in each pathway are covered in code vs impact assessment in Queensland, explained.

What does the waiting time cost you?

Time is a real line item: interest on land debt, rates, insurance, and the opportunity cost of committed equity all run while council assesses. Casa Intelligence analysis of decided applications shows median elapsed lodgement-to-decision times of 28 days in Logan (28,576 decided applications), 42 days on the Gold Coast (34,813), 50 days on the Sunshine Coast (35,018), 51 days in Moreton Bay (14,811), and 52 days in Brisbane (149,392). Since January 2023 the medians are a little slower: Brisbane 62 days, Sunshine Coast 64, Moreton Bay 55, Logan 51, Gold Coast 44.

Those medians cover everything from carports to towers, so calibrate to your project type: Brisbane multiple-dwelling applications show a median of 144 days across 8,258 decided applications, and Sunshine Coast multi-dwelling applications a median of 78 days across 2,625. On a project holding $1.5 million of land debt, every month of assessment is roughly $8,000 to $10,000 of interest at current rates — a six-month DA is a five-figure line item all by itself.

Where do DA budgets actually blow out?

Three places. First, the information request: council may issue one formal request for more information, the clock stops until you answer, and the response typically costs $10,000 to $30,000 in additional consultant work plus two to four months of elapsed time. Second, redesign: if the concept was drawn before the planning constraints were fully mapped, the RFI or a pre-lodgement meeting forces amended drawings — and every consultant downstream of the architect re-issues their report. Third, conditions: approval is not the end of the spend. Casa Intelligence analysis of 637 parsed Sunshine Coast decision notices found a median of 26 conditions per approval, with 68% including stormwater conditions and 40% including an infrastructure charge condition; across 5,307 parsed Gold Coast notices the median was 13 conditions. Conditions carry compliance costs that belong in the feasibility, not in the surprise column.

The common thread is sequencing. Money spent understanding the site before design starts is repaid multiple times over in avoided rework. That is the argument for doing the due diligence before you break ground, not after.

What does the full stack look like on a real project?

Take a worked example: a duplex (dual occupancy) on a compliant 700m² suburban lot, code assessable, no unusual overlays. Council application fee in the low thousands. Town planning report around $8,000 to $12,000 at the small end of the planner range. Drawings suitable for a DA, $10,000 to $20,000. A surveyor and a stormwater response, another $5,000 to $10,000 combined. Application subtotal: roughly $25,000 to $45,000. Then infrastructure charges on the one net additional dwelling — up to $36,670.70 if it is three or more bedrooms — and building approval costs on top. The approval side of a simple duplex is a $55,000 to $80,000 exercise before construction, and the single largest line is the statutory charge, not any consultant.

Now add one flood overlay to the same site: a hydraulic report, possible floor-level changes flowing through the drawings, and a likely information request if it is not addressed upfront. The same project drifts toward $100,000 of pre-construction spend. That sensitivity — one overlay moving the budget 25% or more — is why the cost question and the site question are the same question.

Subdivision behaves similarly but with civil works attached. For a simple two-lot split in SEQ, survey, engineering, application fees, infrastructure charges, and civils (crossovers, service connections, stormwater) commonly total $80,000 to $150,000 — a range we have covered in detail in our SEQ subdivision guide.

What costs arrive after the approval?

The decision notice is not the end of the spend, and budgets that stop at "approval" understate the real number. Conditions routinely require operational works approvals (their own applications, with their own fees and engineering), plan sealing fees for subdivisions, landscaping bonds, and compliance certification at each stage. Infrastructure charges generally fall due when the development actually proceeds — at plan sealing for a subdivision or before occupation for dwellings — which at least pushes them later in the cash-flow, but they arrive in full.

Model conditions as a cost category from day one. The pattern in our parsed decision notices is consistent: stormwater, landscaping, and infrastructure conditions appear on a large share of SEQ approvals, and each carries either a design cost, a works cost, or both.

How do you scope the cost stack before you spend serious money?

Get the site facts first, then brief consultants against a known scope. A $150 Preliminary Planning Report on any SEQ address gives you the zoning, overlays, likely assessment pathway, comparable decided DAs, and the specialist disciplines your site triggers — prepared by a qualified development professional (Master of Architecture) and delivered in minutes. That is the difference between asking an architect to "see what fits" and briefing them with the constraints mapped. If you are still choosing between areas, our suburb-level DA statistics show approval activity and timelines across SEQ before you commit to an address.

If the numbers stack up and you proceed, our $1,999 DA Project service prepares, reviews, and lodges the application with council, coordinating the specialist consultants your site actually requires — so you pay for the disciplines you need rather than a standing army.

The honest caveats

Cost ranges here are calibration figures drawn from our analysis of SEQ applications and published statutory schedules, not quotes; your site, council, and consultants will produce their own numbers. Statutory charge amounts are the 2025–26 indexed figures and change with indexation each financial year. Historical medians describe past council behaviour and guarantee nothing about your application. Verify fees against the current council schedule, charges against the current adopted charges resolution, and everything against the current planning scheme. This is general information, not financial or legal advice.
