A development application costs three things added together: a Council lodgement fee set by regulation and scaled to the value of the works, consultant fees commonly between $3,000 and $10,000 for preparation and management, and the specialist reports your particular site and proposal trigger.
Buyers routinely conflate these three, then get surprised when the total lands well above the Council fee they looked up. They are separate layers, calculated in different ways, paid to different parties. If you are assessing whether a site is worth pursuing, knowing which layer moves with project value and which moves with site constraints is the difference between a usable feasibility number and a guess.
What makes up the total cost of a development application?
The total is Council fees, consultant fees and specialist reports, and only the first of those is fixed by law.
The Council fee is statutory and non-negotiable, calculated from the estimated cost of the development. The consultant fee is competitive and reflects the complexity of the application and the assessment work behind it. The specialist reports are driven by the site and the proposal: a flat, unconstrained site in a straightforward zone triggers few, while a heritage-listed, flood-affected corner site triggers many.
For most applications, the reports are the layer with the widest spread, and the layer people forget when they budget.
How are Council DA fees calculated in New South Wales?
Council fees are calculated under Part 13 of the Environmental Planning and Assessment Regulation 2021, on a sliding scale tied to the estimated development cost.
Three features of that scheme matter to a feasibility:
- The scale is statutory, so Councils are not competing on it. The same works cost the same to lodge regardless of which Council area they sit in, subject to each Council’s additional charges for things like advertising and notification.
- Fees reindex annually. Schedule 4 of the Regulation expresses fees in “fee units” that are recalculated each financial year. Council fee schedules therefore change around 1 July, and a figure carried into a feasibility in May may be stale by settlement.
- There is a separate planning reform fee. Where estimated development cost including GST exceeds $50,000, an additional fee is payable to the Planning Secretary on top of the Council’s fee.
Most NSW Councils publish a fee estimator that will produce the statutory figure from your works cost. Use it early, because it is the one number in the stack you can pin down before you engage anyone.
What is estimated development cost, and why does it decide your fee?
Estimated development cost is the genuine cost of carrying out the development, and it is the input the entire fee calculation runs on.
Getting it wrong is expensive in both directions. Understate it and the Council can form its own view and recalculate, which delays lodgement. Overstate it, and you pay a higher fee than the project warrants.
Two rules changed the way this works. Since 4 March 2024, GST must be added to estimated development cost before certain Schedule 4 fees are calculated, as set out in the NSW Department’s estimated development cost guidance. Above $3 million, the estimate must be prepared by a qualified quantity surveyor who is a member of a relevant professional body, which is itself a cost line in a larger project’s budget.
Estimated development cost covers the cost of building the development and preparing it to operate at capacity. It does not include ongoing operating, maintenance or running costs.
What do town planning consultant fees cost?
Consultant fees for preparing and managing a development application commonly fall between $3,000 and $10,000, with hourly rates across the Australian market running from roughly $120 to over $500.
Where a project lands in that band is driven by the number of issues the application has to argue, not by the size of the building. A straightforward proposal in a compliant envelope sits low. A proposal requiring a written request to vary a development standard, addressing multiple constraints, or heading into public notification with likely objections sits high.
Prestige quotes minimum-fee scopes rather than initially billing hourly, so this layer is generally a known number before work starts rather than a meter running from the get go.
Which specialist reports will your project need?
The reports are determined by the site and the proposal, and they are the largest single variable in the total.
Commonly triggered reports include:
- Survey: a detailed survey of levels, boundaries and existing structures. Required on most applications involving building work.
- Traffic and parking assessment: where the proposal changes vehicle movements or parking demand.
- Acoustic report: where the use generates noise, or where the site is exposed to it.
- Heritage impact statement: where the site is listed, or sits within a conservation area.
- Flood, bushfire or geotechnical assessment: where mapping identifies the constraint.
- BASIX certificate: for residential development in New South Wales.
- Arboricultural report: where trees are to be removed or affected.
- Contamination assessment: where the site’s history suggests a risk and the new use is sensitive.
- Waste management plan: required by most Councils for construction and operation.
Each is paid to that consultant directly. A constrained site can carry more in reports than in Council and planning fees combined, which is why two projects with identical construction budgets can have very different application costs.
What does a DA cost by project type?
The table shows the pattern, not the price. Absolute figures depend on the works cost, the current fee schedule and the constraints on your specific site.
| Project type | Council fee driver | Reports commonly needed | Total DA cost profile |
| Single dwelling, unconstrained site | Low to moderate works cost | Survey, BASIX, waste | Low |
| Dual occupancy | Moderate works cost | Survey, BASIX, waste, arborist, sometimes traffic | Low to medium |
| Commercial fit-out or change of use | Often low works cost | Acoustic, parking, fire and egress, ventilation | Medium |
| Multi-unit residential | High works cost | Full suite, plus design review where applicable | High |
| Mixed-use or shop-top housing | High works cost | Full suite, traffic, acoustic, waste, heritage where relevant | High |
| Heritage or flood-affected site, any scale | Follows works cost | Constraint-specific reports on top of the base set | Disproportionately high |
The final row is the one that catches investors. A modest proposal on a constrained site can cost more to apply for than a larger proposal on a clean one.
If you are running numbers on a site you have not bought yet, this is the point where an early read pays for itself. Our development application services begin with whether the site supports what you intend, before anyone starts drawing.
What costs sit outside the DA fee entirely?
Several high costs are not part of the development application at all, and feasibilities that miss them are wrong by a wide margin.
- Developer contributions. Councils levy contributions towards local infrastructure under their contributions plans, either as a calculated contribution or as a levy expressed as a percentage of development cost. On a larger project, this can exceed every other application cost combined. Check the relevant council’s contributions plan.
- Construction certificate. After consent, the construction certificate is a separate approval with its own fee, whether through Council or a private certifier.
- Certifier and inspection fees. The principal certifier charges for the certificate and for mandatory inspections during construction.
- Occupation certificate. Another separate approval before the building can be occupied.
- Long service levy. Payable on building and construction work above a threshold, before the construction certificate is issued.
- Design and documentation. Architectural and engineering documentation is usually the highest professional cost on the project, and it is not a planning fee.
A feasibility built on the DA fee alone understates the approval pathway substantially.
Why does the cheapest application often end up the most expensive?
The cheapest application costs the most when it triggers a request for information, a refusal, or an appeal.
Council’s assessment period for a standard development application is 40 days under the EP&A Regulation, extending to 60 days for designated, integrated or concurrence development and 90 days for State significant development. That clock stops when Council issues a request for information, and it does not restart until you answer.
A thin application does not shorten that timeline. It lengthens it, because the assessment stalls on the material that was left out. Where an application is refused or not determined in time, the applicant has six months from the refusal or deemed refusal to commence a Class 1 appeal in the Land and Environment Court. An appeal costs considerably more than the reports that would have avoided it.
Holding costs run through all of it. Interest, rates and rent do not pause while an application sits unanswered.
When is it worth spending on advice before you lodge?
It is worth it when the answer could be no.
For a compliant proposal on a clean site, the application is largely a documentation exercise. For a site you are considering buying, a proposal that varies a development standard, or a use whose permissibility is uncertain, the cost of finding out early is a fraction of the cost of finding out late.
Prestige Town Planning’s stated position is that if a site cannot support what you are trying to build, you hear it on the first call, and that the firm would rather lose a brief than walk a client into a refusal. For a developer weighing sites, that is the only part of the process that saves money rather than spending it.
How do you turn this into a real number for your site?
Separate the three layers, then get the reports scoped against your actual site rather than a generic one. That is the difference between a feasibility figure you can rely on and a placeholder.
Prestige Town Planning prepares and manages development applications Nationally, including the 33 Greater Sydney Councils, from an office in East Gosford. The firm offers minimum-fee scopes and states that it does not bill for work you do not need.
