Property Development Feasibility Studies in Adelaide: The Complete Guide
A property feasibility study Adelaide developers can rely on tests one question before any money is committed: does this site, under the Planning and Design Code, produce a return that justifies the cost and the risk? A good study stacks up realistic revenue against every line of cost — land, statutory fees, professional fees, construction, holding costs and contributions — and stress-tests the result against time and market movement. Below we walk through the inputs that matter most in South Australia, with the statutory figures you can anchor to and the planning-range estimates you should treat with care.
What a feasibility study actually measures
At its core, a feasibility study answers whether a project is viable and under what assumptions. It typically models:
Revenue — the expected end value of the allotments or dwellings.
Acquisition — land cost, plus stamp duty and related transfer costs.
Statutory costs — development application (DA) lodgement fees, open space contributions, and Lands Titles Office charges.
Professional and construction costs — surveying, engineering, design, and the build itself.
Holding costs — land tax, finance, and time on market.
The discipline is in being conservative on revenue and complete on cost. The largest variables in Adelaide are usually construction cost and time-to-approval, so both deserve close scrutiny. The cost baseline itself has moved — the NCC's 7-star energy and accessibility provisions now sit under every new dwelling — and on the revenue side a bank valuation below your expectation changes what you can borrow. What the two ends leave you with is the profit-on-cost margin, which is the number that decides whether the project is worth doing at all.
A sample feasibility (illustrative only)
The table below shows how a feasibility model assembles. The figures are illustrative placeholders for a notional one-into-three townhouse project — they are not a quote and not a forecast for any real site. Real inputs change with the address, zone, slope, services, finish and market timing, which is exactly why a site-specific report matters.
Land cost: $900,000
Stamp duty (acquisition): $48,000
DA / PlanSA lodgement fees: $3,500
Open space contribution (in lieu): $30,500
SA Water / service connections: $25,000
Professional fees (survey, design, engineering): $60,000
Construction (3 townhouses): $1,350,000
Holding / interest cost: $95,000
Contingency (~5%): $120,000
Total project cost: $2,632,000
Sale revenue (3 dwellings): $3,150,000
Less selling/agent costs: $63,000
Less GST allowance: $127,000
Margin-scheme assumption: GST estimated under the margin scheme (illustrative)
Net revenue: $2,960,000
*Margin (net):* ~$328,000 (≈12.5%)
All figures above are illustrative and rounded for explanation only. A robust model would label the financial year, attach a source to every statutory line, and run sensitivity on the two biggest swing factors — construction cost and time on market.
The statutory cost inputs (South Australia)
These are set by government and are usually the most reliable numbers in any model. Note: most South Australian statutory fees are reviewed and updated on 1 July each year, so the figures below should be checked against the current annual fee schedule before you rely on them. The 2026-27 Planning, Development and Infrastructure (Fees) Notice 2026 has been published and takes effect from 1 July 2026.
Development application fees. In South Australia, DA lodgement fees are set by the Ministerial fee notice and increase with total development cost, excluding fit-out. Under the 2026-27 fees notice, the lodgement fee ranges from $98.50 for development not exceeding $10,000 to $6,308 for development exceeding $10 million — for example, $3,442 for a $1m–$5m project and $4,588 for a $5m–$10m project. If you do not lodge electronically, an additional paper processing fee of $95.50 applies. Check the current annual fee schedule on PlanSA (Source – Application fees; SA Government Gazette – Planning, Development and Infrastructure Fees Notice 2026).
Open space contributions (land division). For a division, you may need to provide open space — for divisions creating 20 or more allotments, this usually involves an open space land requirement — or pay a financial contribution in lieu to the Planning and Development Fund. Under the 2026-27 fees notice, the contribution is $10,166 per new allotment or strata lot not exceeding 1 hectare in Greater Adelaide, and $3,723 per new allotment or strata lot not exceeding 1 hectare in other parts of South Australia. Before modelling, verify the current rate and specific applicability conditions (Source / PlanSA – Open space contributions; SA Government Gazette – Planning, Development and Infrastructure Fees Notice 2026).
Lands Titles Office (Land Services SA) fees.Land division fees payable to Land Services SA are set by the Real Property (Fees) Notice and cover examination of the plan of division, deposit / lodgement processing, and issuing new Certificates of Title. Land Services SA provides an online LTO fee calculator to total these fees; because these fees are also usually updated around 1 July each year, use the current annual calculator (Source Services SA – Fees and Charges).

A deeper breakdown of subdivision-specific outlays sits in our guide to the cost to subdivide land in Adelaide.
Holding costs: land tax in SA
Land tax is an ongoing holding cost across the project lifecycle. In 2026-27, South Australia’s general land tax tax-free threshold is $936,000, up from $833,000 in 2025-26, with progressive rates applying above that threshold. Thresholds are indexed each year based on the average movement in site values determined by the Valuer-General, so a feasibility study should identify the financial year and refresh the figures annually. Also note that land held through a trust may be subject to a lower starting threshold (Source – Land tax rates and thresholds).
Construction and subdivision cost ranges
Unlike statutory fees, construction and subdivision costs are not published by government — they come from surveyors, builders and cost guides, and vary significantly depending on finish level, slope, services and demolition. Treat the following figures as planning ranges, not quotes.
Construction (2025 Rawlinsons data). Medium-standard townhouses are approximately $2,290–$2,465 per square metre (higher standard: $2,560–$2,760 per square metre); medium-finish one- or two-bedroom apartments with no balconies or lifts start from approximately $1,580 per square metre; detached houses are generally around $1,700–$3,200 per square metre, depending on quality (Source via AS Estimation).
One-into-two subdivision. Commonly estimated at approximately $26,000–$35,000 all-inclusive, with surveying fees generally starting from around $2,000, council / DA and title lodgement fees around $1,000, civil works potentially reaching tens of thousands of dollars, and fencing around $60–$200 per metre (Source Surveyors Adelaide).
Independent estimates. Another guide estimates South Australian DA costs at approximately $2,000–$15,000, depending on development value, and notes that development contributions are one of the less transparent and more easily underestimated cost categories, ranging from around $5,000 to $40,000+ per dwelling in some high-growth areas (Source – Feasibility Guide).
The figures above exclude land cost, and in the case of subdivision figures, exclude construction cost. Tender prices may move with the market, so include contingency and escalation assumptions in your model.
What a bad feasibility misses
The difference between a model that protects you and one that lulls you usually comes down to the costs and delays that never make it onto the spreadsheet. Common omissions include:
Stormwater and detention. On-site detention, soakage or upgraded drainage can be a five-figure surprise, especially on flat or built-up Adelaide allotments.
Service upgrades. SA Water main extensions, sewer connections, SA Power Networks augmentation and NBN lead-in are often assumed away rather than priced.
Interest and holding cost. Finance, rates and land tax accrue for every month the site is held — a frequent blind spot when approvals or sales run long.
GST. New residential sales typically attract GST; ignoring it (or the margin scheme) can quietly erase the profit line.
Market delay. Slower presales or settlements extend holding costs and can compress the achievable end value.
Title delay. Time at the Lands Titles Office before new Certificates of Title issue defers revenue and lengthens the holding period.
Builder cost escalation. Tender prices and variations have been trending up; a model fixed at today's rate can be out of date by the time you build.
For how these risks shift across the broader approval journey, see our walkthrough of the SA development approval (DA) process.
Timeframes and approval pathway
In a feasibility study, time is money, so the assessment pathway directly affects holding costs. South Australia’s planning system under the Planning, Development and Infrastructure Act 2016 (PDI Act 2016) uses set timeframes: most assessment pathways include a 5-business-day verification period at the start and a 2-business-day period for issuing the decision at the end. Deemed-to-satisfy development is usually assessed more quickly. If the relevant authority misses the prescribed timeframe, the applicant may, where applicable, issue a Deemed Planning Consent Notice, after which the authority has 10 business days to issue the formal consent (Source – Stages and timeframes).
Land division is processed electronically through the PlanSA portal, assessed against the Planning & Design Code, and may be referred to agencies such as SA Water and SA Power Networks. Under the PDI Act 2016 and the Real Property Act 1886, development approval must be obtained before land can be divided, and the final Plan of Division is lodged with the Lands Titles Office before new Certificates of Title are issued (Source – Land division consent). Independent commentary considers South Australia’s land division process relatively centralised and clear compared with other Australian jurisdictions. Simple divisions may sometimes progress to approval or near-title stage in around six months, but actual timing still depends on referrals, clearances, engineering requirements and Land Services SA examination (Source – Land Subdivision guide).
Yield, buyers and the foreign-investment overlay
A feasibility study also needs to be realistic about “who will buy”. South Australia has abolished stamp duty for eligible first home buyers — whether they are buying or building a new home, an off-the-plan apartment, a house-and-land package, or vacant land to build on — and for contracts entered into on or after 6 June 2024, the property value cap has been removed. The First Home Owner Grant is a one-off payment of up to $15,000, and from 6 June 2024 it also has no property value cap (Source – First home buyer relief). For projects aimed at overseas buyers, note that from 1 April 2025, foreign persons are prohibited from purchasing established dwellings, with the ban announced in the 2026-27 Budget as extended to 30 June 2029. The policy direction is to steer foreign investment towards new housing and development (Source – Banning foreign purchases). FIRB residential fees are indexed on 1 July each year; in 2025-26, the minimum notifiable action fee for residential land other than established dwellings was $4,500, while the same value bracket for established dwellings was $13,500. Residential land exemption certificate fees are calculated by category and value band; verify the current annual fee before relying on it (Source – Fees for foreign residential investors; FIRB / Treasury – Schedule of Fees).
There is one thing a feasibility study cannot shortcut: minimum lot size and frontage width are not single statewide numbers — they are set zone by zone in the Planning & Design Code and may be modified by local Technical and Numeric Variations. Always use the online Code’s “what policies apply to an address” tool to check the specific address (Source – Planning and Design Code). Where landowners and developers are sharing the upside, our guide to a fair landowner JV profit split in Adelaide shows how the feasibility margin flows through to each party.
Frequently asked questions
Q: What is a property feasibility study? It is a financial and planning analysis that tests whether a development site stacks up — comparing realistic end revenue against all costs (land, statutory fees, construction, contributions and holding costs) and the time required to deliver, before you commit funds.
Q: How much are development application fees in South Australia? Under the 2026-27 fees notice, DA lodgement fees increase with total development cost, from $98.50 for development not exceeding $10,000 to $6,308 for development exceeding $10 million. If the application is not lodged electronically, a $95.50 surcharge applies. Check the current annual fee schedule on PlanSA (Source; SA Government Gazette).
Q: How much does it cost to subdivide one block into two in Adelaide? Commercial guides commonly estimate a one-into-two subdivision at approximately $26,000–$35,000 all-inclusive, excluding land and construction, but this varies depending on site conditions, services and civil works (Source Surveyors Adelaide).
Q: How long does a subdivision take to approve in SA? Independent commentary suggests straightforward subdivisions are often approved in the order of around six months; statutory pathways also include fixed verification and decision periods under the PDI Act 2016 (sources: Feasly; PlanSA).
Q: Is there a minimum lot size for subdivision in South Australia? There is no single statewide minimum — requirements are set zone-by-zone in the Planning and Design Code and can be varied locally, so check the specific address in the online Code (source: PlanSA).
