How to subdivide land in South Australia

Can I subdivide my block in South Australia? Possibly. Whether you can subdivide land in South Australia depends on three things: your zone under the Planning and Design Code, whether the block is big and wide enough to meet that zone's minimum site area and frontage for the homes you have in mind, and whether anything such as a heritage listing, a bushfire or flood overlay, protected trees or servicing limits gets in the way.

The official South Australian term is land division, not subdivision. To split a block you need land division consent and planning consent under the Planning, Development and Infrastructure Act 2016. People search for "subdivision", but PlanSA forms, fees and decisions say "land division".

This guide covers who approves a land division, the rules that apply, each step to new titles, timeframes, official 2026–27 fees and common problems.

Who approves a subdivision in South Australia

South Australia has one statewide planning system, run through PlanSA, and the rules for every property sit in the Planning and Design Code, made under the Planning, Development and Infrastructure Act 2016 (the PDI Act). Your land division consent and planning consent together form your development approval.

Who decides depends on the application:

The council's assessment manager can grant land division consent for all development, except where the State Planning Commission or the Minister for Planning is the authority. The assessment manager also decides planning consent for deemed-to-satisfy development and for performance assessed development that is not publicly notified.
An accredited professional surveyor can grant land division consent where no public road is created.
The council assessment panel decides planning consent for performance assessed development that is publicly notified.
The State Planning Commission assesses restricted development, and the Minister for Planning handles declared major projects, Crown development and essential infrastructure.

Some applications are referred to state agencies under Schedule 9 of the Planning, Development and Infrastructure (General) Regulations 2017, mostly because of Code overlays. Agencies include the State Heritage Unit, the Native Vegetation Council, the SA Country Fire Service and the EPA. SA Water usually deals directly with your surveyor on water and sewerage requirements.

At the end, Planning and Land Use Services issues the Land Division Certificate of Approval (section 138 of the PDI Act), and Land Services SA deposits the plan and issues new titles. Rights of review and appeal are in section 202, and appeals go to the Environment, Resources and Development Court.

The rules that decide whether your block can be split

Your zone. Search your address on the South Australian Property and Planning Atlas (SAPPA) and open the Planning and Design Code layers, or use the property search in the online Code at code.plan.sa.gov.au. The Code changes through Code Amendments, so read the version currently in effect.

Minimum site area and frontage. There is no single minimum lot size in SA. Each zone's land division rules set a minimum site area and frontage (the lot's width along the road), and the figures can differ for detached, semi-detached, row or group dwellings. In some areas a mapped Minimum Site Area or Minimum Frontage technical and numeric variation (TNV) sets the figure that the zone's policy uses, so check SAPPA for a TNV too.

Deemed-to-satisfy or performance assessed. Code rules are written as performance outcomes, with deemed-to-satisfy or designated performance feature (DTS/DPF) criteria beside them. A deemed-to-satisfy proposal must be granted planning consent. A performance assessed proposal is judged on its merits and may involve referrals or public notification. Missing a DTS/DPF figure is not an automatic refusal, but the proposal has to show the outcome is met another way.

Battle-axe (hammerhead) lots. A rear lot reached by a driveway "handle" is common in Adelaide infill. Zone rules can treat a battle-axe site differently, so check how your zone treats them.

The existing house. If it stays, its yard, parking and access must still work under the Code on the smaller lot.

Torrens or community title. Land Services SA describes Torrens title as at least two allotments held independently, and community title as at least two lots plus common property, such as a shared driveway. New strata divisions can no longer be created.

Environment and food production areas. Around Greater Adelaide, section 7(5)(d) of the PDI Act requires refusal of a land division creating additional allotments for residential development in an environment and food production area. PlanSA notes these applications have not been permitted since the transitional period ended on 31 March 2019.

Step by step: the subdivision process in South Australia

Check the planning rules. Look up your zone, overlays and any TNV on SAPPA or in the online Code.
Read your certificate of title. A Land Services SA register search shows easements, encumbrances and any land management agreement, which becomes binding once noted on the title.
Engage a licensed surveyor. The surveyor prepares the proposed plan of division and usually manages the application. A town planner can help where the proposal is performance assessed.
Consider preliminary advice. Under section 123 of the PDI Act you can reach an agreement with a referral agency before lodging. It must be lodged within one year of signing, and it avoids a formal referral later.
Lodge through the PlanSA portal. The application seeks planning consent and land division consent, and lodgement and assessment fees are paid now. A five business day verification period follows.
Assessment. The relevant authority assesses the proposal against the Code, sends any referrals, runs public notification if required, and may request more information.
Decision. You receive a Decision Notification Form setting out the consent and conditions. Regulation 67 of the General Regulations governs when consents and approvals lapse, so check how long yours stays current.
Meet the conditions. Typically SA Water's requirements and charges, council requirements, and works such as service connections, driveways or demolition.
Apply for the certificate. After development approval, apply in the PlanSA portal and pay the land division fee and open space contribution. Planning and Land Use Services issues the Land Division Certificate of Approval.
Get new titles. Your surveyor or conveyancer lodges the plan with Land Services SA, which examines it, deposits the plan and issues the new certificates of title.

How long it takes

Statutory clocks are set under section 125(1) of the PDI Act and regulation 53 of the General Regulations. PlanSA publishes them in business days:

Verification: five business days at the start, plus two at the end for the decision to issue.
Land division consent: 30 business days for a division into 10 allotments or fewer (including an encroachment) with no new public road; 60 business days for all other land division.
Planning consent: 5 business days if deemed-to-satisfy; for performance assessed, 20 business days, 50 with a referral, or 70 with public notification.

The clock can be suspended while further information is requested, and restarts when it arrives. If the authority misses its planning consent deadline, section 125 and regulation 54 let you serve a deemed consent notice, and the authority then has 10 business days to grant consent with conditions.

These are assessment times only. Conditions, service works, the certificate and new titles usually take longest; Land Services SA notes a land division can take many months.

What it costs

Planning fees are set statewide by the Planning, Development and Infrastructure (Fees) Notice 2026, applying from 1 July 2026. Land Services SA fees also apply from 1 July 2026, and SA Water's augmentation charges to SA Water development approvals from 1 July 2026 to 30 June 2027. Figures are current at October 2026 and change annually.

Fee (official source)	Amount
PlanSA lodgement fee (Fees Notice item 5)	$98.50 where total development cost is $10,000 or less, rising in bands to $6,308 above $10 million
Planning consent, deemed-to-satisfy (item 6)	$151 (development cost $10,000 or less) or $250
Planning consent, performance assessed (item 6)	$299 or 0.125% of development cost up to a maximum of $200,000, whichever is greater
Public notification, where required (item 7)	$299
Referral fee (item 8)	$476 standard (including the CFS); Native Vegetation Council $763
Land division fee (item 14)	$210 where no more than 4 additional allotments and no public road; otherwise plus $19.10 per additional allotment
Water and sewerage assessment (item 27)	$480, and $138 for each update
Certificate of Approval (item 17, s 138)	$1,229
Open space contribution (item 25)	$10,166 per new allotment of 1 hectare or less in Greater Adelaide; $3,723 elsewhere
Land Services SA survey plan	$1,231 examination, $189 deposit, $188 Survey Act levy, $112 per new title
SA Water augmentation, Greater Adelaide residential	Water and wastewater each $4,017 (infill) or $5,356 (greenfield) per additional allotment or new connection

The open space contribution is paid into the state's Planning and Development Fund in place of land for divisions into 20 or fewer allotments and for strata and community titles. A community plan of five lots or fewer has a lower examination fee of $618.

Everything else is site-specific and quoted privately: surveyor, any town planner, SA Water and SA Power Networks connections, main extensions, stormwater and driveways, demolition, specialist reports and conveyancing. Totals vary widely by site.

Things that can stop or complicate a subdivision

State and local heritage. State Heritage Places are listed in the South Australian Heritage Register under the Heritage Places Act 1993. Local Heritage Places, Historic Areas and Character Areas are overlays in the Planning and Design Code. A listing does not automatically rule out a land division, but it shapes the assessment and can bring a heritage referral.

Aboriginal cultural heritage. Information on the Register of Aboriginal Sites and Objects under the Aboriginal Heritage Act 1988 is subject to legislative and cultural restrictions. Searches are requested from the Attorney-General's Department through the Taa wika system or by email; the basic search fee is $27.75 and you should allow up to 21 days. The Register is not an exhaustive record of all Aboriginal heritage sites in South Australia.

Bushfire. The Code's Hazards (Bushfire) overlays can trigger a referral to the SA Country Fire Service, which looks at siting, emergency vehicle access, vegetation clearance and firefighting water supply. Ministerial Building Standard MBS 008 adds building requirements in designated bushfire prone areas.

Flooding. The Code has three flood overlays: Hazards (Flooding), Hazards (Flooding – General) and Hazards (Flooding – Evidence Required). The last is an interim overlay where no flood hazard data exists. Being outside the mapped overlays is not the same as having no flood risk.

Native vegetation and trees. Clearing native vegetation needs approval under the Native Vegetation Act 1991, and the Native Vegetation Council must be satisfied there will be a significant environmental benefit, through on-ground work or a payment into the Native Vegetation Fund. Where the Regulated and Significant Tree Overlay applies (mainly metropolitan Adelaide and some townships), a regulated tree has a trunk circumference of 1 metre or more and a significant tree 2 metres or more, measured 1 metre above natural ground level. Removing or damaging one needs development approval.

Contamination. The EPA's Site Contamination Index is searchable by suburb or council and lists information the EPA has received, so past uses such as a service station or fill matter too.

Easements, covenants and agreements. The certificate of title can show easements (for example, for sewer mains), encumbrances and land management agreements that limit building or division.

Servicing. Each new allotment needs water, sewer, power and stormwater. Where mains do not reach the lot or need upgrading, cost and time can rise sharply.

Existing buildings. A shed, garage or house that would straddle a proposed boundary has to be altered or removed.

A quick checklist for your block

What zone is the land in, and does a Minimum Site Area or Minimum Frontage TNV apply?
Does the block meet the minimum site area and frontage for the homes planned?
Is the land in an environment and food production area?
Would side-by-side lots or a battle-axe layout suit the frontage better?
If the house stays, can it still work on its smaller lot?
Does the title show easements, encumbrances or a land management agreement?
Do heritage, bushfire, flood, native vegetation or regulated tree overlays apply?
Are SA Water sewer and water mains available at the street?
Is Torrens or community title the better fit?

Where a Subdivision Checker report fits

A Subdivision Checker report brings together the planning rules, mapping and records for one address in South Australia in one professional report: planning and zoning, including the minimum lot size rules that apply, heritage, environment, bushfire, flood, servicing, contamination and title, plus indicative costs. It is a starting point that helps you understand your block and know what to ask a licensed surveyor or town planner. It is not a substitute for their advice. Order a report for your address.

Frequently asked questions

Is subdivision called something different in South Australia?

Yes. The official term is land division. Under the Planning, Development and Infrastructure Act 2016 you need land division consent and planning consent, and together they form your development approval. Most people search for subdivision, but PlanSA forms, fees and decisions use land division, so it helps to know both terms.

What is the minimum block size to subdivide in South Australia?

There is no single statewide minimum. Each zone in the Planning and Design Code sets its own minimum site area and frontage, and the figure can change with the type of dwelling planned. In some places a Minimum Site Area or Minimum Frontage technical and numeric variation sets the figure that the zone's policy uses. You can check your zone and any variations on the SA Property and Planning Atlas.

How long does a land division take in South Australia?

Land division consent has a statutory assessment time of 30 business days for a division into 10 allotments or fewer with no new public road, and 60 business days for all other land division. Planning consent runs to its own timetable. Meeting conditions, servicing works, the certificate of approval and new titles usually take much longer than the assessment itself.

Who issues the land division certificate in South Australia?

The Land Division Certificate of Approval is issued by Planning and Land Use Services, not by the council. You apply for it through the PlanSA portal once development approval has been granted, and pay the land division fee and open space contribution at that stage. The certificate is what allows the surveyor's plan to be deposited with Land Services SA so new titles can issue.

What does it cost to subdivide land in South Australia?

Official fees include PlanSA lodgement and assessment fees, a $210 land division fee where no more than four additional allotments and no public road are created, a $1,229 certificate of approval fee, and an open space contribution of $10,166 per new allotment of 1 hectare or less in Greater Adelaide or $3,723 elsewhere. Surveying, servicing and titles add more, and totals vary widely by site.
