INSIGHT · PLANNING & APPROVALS

Before a South Australian site is bought,
every official answer has a date and a version.

9 October 2026

A developer checking a residential site in South Australia before purchase reads zoning and overlays from the Planning and Design Code, ownership and dealings from a Land Services SA register search, contamination records from the EPA's index and its section 7 statement, heritage listings from the SA Heritage Register, and servicing from SA Water. Each answer is dated. As read on 9 October 2026, the Code in effect was Version 2026.19, dated 8 October 2026, and the EPA states its index is updated monthly. A feasibility check stored without its source, version and date cannot be re-checked.

Analysed 9 October 2026 · PlanSA and Planning and Design Code pages (Code version 2026.19 dated 8 October 2026) · Land Services SA title, Title Watch and 2026-27 fee pages · EPA site contamination, index and section 7 pages · Department for Environment and Water SA Heritage Register page · SA Water connection and 2026-27 augmentation pages · all pages read 9 October 2026, the PlanSA, Code and SA Water pages through a rendering proxy because those sites block automated access.

Key takeaways

The zoning answer belongs to a Code version: PlanSA lists 17 historic versions of the Planning and Design Code for 2026, from Version 2026.1 (15 January 2026) to Version 2026.17 (10 September 2026), most of them operational for two weeks (our reading of the listed dates). The online Code showed Version 2026.19, dated 8 October 2026, when read on 9 October 2026.
The EPA's index is useful and, in its own words, not exhaustive: The EPA describes its site contamination index as a list of sites for which it holds information in the public register, updated monthly, and states it is not an exhaustive list. The EPA Statement for a Form 1 answers 33 questions and costs $23.00 per current certificate of title.
A title search is cheap, and dated the moment it is run: Under the Real Property (Fees) Notice 2026, the statutory fee for searching the Register Book is $36.75 or $45.50 depending on what it includes (GST exempt, 2026-27 schedule). Online orders are priced under the SAILIS Price List, which we did not read. Land Services SA's Title Watch exists to report activity on a title after that date.
SA Water's map is an estimate, and the charge follows approval: SA Water states its Connections Estimator Map gives estimations as a guide only. Its 2026-27 augmentation charges apply to development approvals given between 1 July 2026 and 30 June 2027 in the Greater Adelaide Region, and must be paid before SA Water clears titles.
We would store each check as a dated record: A system-design recommendation: for every site, record each source checked, the version or currency date it showed, the date it was read, the cost and the reference, and keep the document itself.

Zoning and overlays:
the Code, and which version of it.

PlanSA states that every part of South Australia is zoned, that the South Australian Property and Planning Atlas (SAPPA) displays current zoning, and that zoning is set out by the Planning and Design Code under the Planning, Development and Infrastructure Act 2016. The Code "contains the planning rules and policies that guide what can be developed", and a code amendment is "a proposal to change the policies, rules, or mapping within the Code".

In the version table below, 2026.18 does not appear: it was not on the historic versions page when we read it. On one of our reads on 9 October 2026 the Code home page showed a scheduled maintenance notice saying policies for a property could not be viewed. A zoning check needs the version it was read against, because the same address can return different policies a fortnight apart.

Code version	Operational, as PlanSA lists it	Amendments listed against it
2026.15 (13 August 2026)	13 August 2026 to 26 August 2026	Section 76 amendments (Gazette, 13 August 2026); one section 73 Code Amendment
2026.16 (27 August 2026)	27 August 2026 to 9 September 2026	Section 76 amendments (Gazette, 27 August 2026)
2026.17 (10 September 2026)	10 September 2026 to 23 September 2026	Section 76 amendments (Gazette, 10 September 2026); two section 73 Code Amendments
2026.19 (8 October 2026)	Shown as "P&D Code (in effect)" on the online Code, 9 October 2026	Not listed on the historic versions page at the time of reading

Title:
what a register search carries.

Land Services SA describes a certificate of title as an official record of land ownership in South Australia, and states that a copy is also called a Register Search. It is ordered through the South Australian Integrated Land Information System (SAILIS), by address, title reference, plan and parcel reference or valuation number, and a fee applies. Register Search Plus provides a copy of the register search, the plan and associated dealings.

Fees for 2026-27, GST exempt: The Real Property (Fees) Notice 2026, published by Land Services SA in its 2026-27 schedule, sets $36.75 for a search comprising an unregistered document search statement, a copy of the certificate of title, a check search and a historical search, and $45.50 for a search of the electronic records that also includes the plan image and all registered instruments and dealings. A check search through SAILIS has no fee; a historical search is $2.95.
A search is a snapshot; Title Watch reports what comes after: Title Watch is a subscription that sends an email, and an optional SMS, when activity is detected against a selected title, with up to 20 titles per subscription. Triggers include the purchase of a Property Interest Report or Form 1 product, the lodgement of a priority notice (which Land Services SA says is generally lodged up to 60 days before settlement), and the lodgement of a document such as a transfer, mortgage, lease or caveat.

Contamination:
two EPA sources, and what each says it is not.

The EPA's site contamination page tells prospective purchasers to carry out careful, thorough pre-purchase enquiries, and points to two of its sources: the site contamination index and the section 7 statement for a certificate of title. It also states that, from 19 March 2021, the planning system under the Planning, Development and Infrastructure Act 2016 includes a standardised framework to assess and manage risks from known or potential site contamination.

The site contamination index: A list of sites for which the EPA holds information in the public register, searchable by suburb or town or by council. Each entry gives an EPA reference number, the type of record, the site address and any recorded potentially contaminating activity. The EPA states "This is not an exhaustive list", and that the index is updated monthly with the date of currency published above the search bar. The search page showed "Last updated: 9 October 2026" when read.
Audit reports describe the site on the day they were finished: The EPA states that reports are based on the condition of the site and the information reviewed at the time they are completed, and do not represent any changes since. It advises anyone relying on them to check their currency.
The EPA Statement for a Form 1: The EPA states that sections 7 and 8 of the Land and Business (Sale and Conveyancing) Act 1994 require a statement of government interests to be provided by the vendor or their agent to a prospective purchaser prior to settlement. The EPA's part answers 33 questions about charges and encumbrances, current and historical licences and exemptions, and site contamination records. It costs $23.00 per current certificate of title, and the EPA has a statutory time frame of 8 clear business days to provide it.

Servicing:
SA Water's estimate, and the charge that follows approval.

SA Water's Connections Estimator Map lets a user check whether a connection service is available in an area, where a connection point may exist on a property, and the distance to the available service. Its terms state that the asset and measurement information are estimations provided as a guide only, that SA Water cannot guarantee their completeness or reliability, and that connection availability, requirements and charges are subject to its connections policy, a site check and application review. The map notes that a distance above 12 metres may incur additional charges.

Augmentation charges for 2026-27: SA Water states that the 2026-27 charges were approved by the South Australian Government and apply to persons who receive SA Water development approval between 1 July 2026 and 30 June 2027 for an additional allotment, a new connection or a variation with more than one new premises in the Greater Adelaide Region. The amounts are in separate water and wastewater schedules, which we did not read.
Payment comes before title clearance: The charges are to be paid before SA Water's clearance of titles or construction of new or upgraded connections. Under a Developer Agreement Formal Instrument payment can be deferred, in which case the charge is that of the financial year in which payment is made, and SA Water registers a caveat on the title until it is paid.
Exclusions as listed: SA Water lists exclusions for a like-for-like replacement of an existing connection, connections to premises built by or for a community housing provider or a registered not-for-profit, and an apartment.

The sources side by side.

Each source answers one question and says something about its own limits. Costs are as published for 2026-27 where a page states one.

Beyond the sources compared below, two further items appear on PlanSA's development application checklist: most applications require a signed Electricity Declaration, showing the development is a safe distance from power lines, and a Native Vegetation Declaration, showing it does not clear native vegetation. Both are site facts a feasibility can check before purchase.

Source	What it shows	What it says about its limits or currency	Cost as published
Planning and Design Code (online, and SAPPA for zoning)	Zones, policies and overlays that apply to an address	Versioned: 2026.19 dated 8 October 2026 in effect when read; historic versions listed with operational dates	None stated on the pages read
Land Services SA register search	Ownership record, with plan and dealings in Register Search Plus	Current at the time of the search; Title Watch reports later activity	$36.75 or $45.50 statutory Register Book search fee (GST exempt); historical search $2.95; online orders priced under the SAILIS Price List, not read
EPA site contamination index	Sites with EPA public register records: reference, record type, address, potentially contaminating activity	"Not an exhaustive list"; updated monthly; audit reports reflect the site when completed	Index search: none stated; information on a listed site obtained by contacting the EPA, a fee applies to property enquiries
EPA Statement (Form 1, section 7)	Answers to 33 questions on charges, licences, exemptions and contamination records for a title	Ordered against a current certificate of title; up to 8 clear business days	$23.00 per current certificate of title
SA Heritage Register (Department for Environment and Water)	2,351 confirmed State Heritage Places and 17 State Heritage Areas; the SA Heritage Places Database also shows Local Heritage Places	The page lists current provisional entries open for comment	Certified copy of an entry $43.75 (2026-27), up to 8 business days
SA Water Connections Estimator Map	Whether a service is available, likely connection point, distance	"Estimations", "a guide only"; subject to policy, site check and review	None stated for the map; augmentation charges set by 2026-27 schedules

What we would put in a system

In our experience, pre-purchase checks end up as a folder of PDFs and an email thread, and the feasibility spreadsheet carries a yes or no. When the purchase goes ahead months later, nobody can say which Code version the zoning came from or how old the EPA answer was. For each site, we would test for four fields.

Where agents help is narrow. A feasibility agent can read a register search, an EPA Statement or a Code extract, pull out the identifiers, version, dates and listed items, and draft the check record; a person confirms it. No agent decides whether a site is contaminated, developable, heritage-affected or serviceable. Those are for the relevant authority, SA Water and your consultants.

Field	Why it is load-bearing
Site identifiers: title reference, plan and parcel, valuation number	Land Services SA accepts each of these to find a title, and the EPA Statement is ordered against a current certificate of title. One site record holding all of them avoids checking the wrong parcel.
For each check: source, version or currency date, date read	Code versions in 2026 were mostly operational for two weeks (our reading of PlanSA's dates), the EPA index is updated monthly, and the Heritage Register page lists provisional entries open for comment. A result without these cannot be re-checked or compared.
Cost, reference number and the document itself	Register search, EPA Statement and certified heritage copy each have a published fee and produce a document. Keeping the document keeps the evidence, not just the conclusion.
Who checked, and what they recorded as the finding	A named person's reading of the result, kept separate from the source document, so a later reviewer can see what was relied on.

Questions worth asking
of your own site files

For a developer: for the last site you bought, which Code version did the zoning check use?

PlanSA's listed 2026 versions were mostly operational for two weeks each (our reading of the listed dates). If the feasibility only records the zone name, there is no way to tell whether the policies were read before or after an amendment.

For an acquisitions manager: how old was the EPA answer when the contract was signed?

The index is updated monthly and audit reports describe the site when they were completed. The date of the EPA Statement and the index currency date both belong in the record.

For a development manager: is SA Water's connection estimate stored as an estimate?

SA Water describes the map's figures as estimations and a guide only. A feasibility that uses them as a cost should say so, and note that augmentation charges follow the financial year of approval or, if deferred, of payment.

For a feasibility analyst: could someone else repeat each check from what you stored?

Only if the source, the identifier used, the version or currency date and the read date are in the record, with the document attached.

Questions people ask
about SA site due diligence

How do I check the zoning of a property in South Australia?

PlanSA directs users to the South Australian Property and Planning Atlas (SAPPA), which displays current zoning, and to the online Planning and Design Code, which shows policies for an address. The Code is versioned: on 9 October 2026 the version in effect was 2026.19, dated 8 October 2026.

How much does a title search cost in South Australia?

Under the Real Property (Fees) Notice 2026, as listed in Land Services SA's 2026-27 fees, the statutory fee for searching the Register Book is $36.75, or $45.50 for the version that includes the plan image and all registered instruments and dealings. The fees are GST exempt. A check search through SAILIS has no fee.

How do I find out if land is contaminated in South Australia?

The EPA points purchasers to its site contamination index and to the EPA Statement for a certificate of title. The index lists sites with public register records, is updated monthly and is not exhaustive by the EPA's own statement; the EPA Statement answers 33 questions for $23.00 per current title. Neither is an assessment of the site.

How do I check if a property is heritage listed in SA?

The Department for Environment and Water's SA Heritage Register page points to the South Australian Heritage Places Database, which shows Local and State Heritage Places, Objects and Areas, and to NatureMaps. The page states that 2,351 confirmed State Heritage Places are entered in the Register and 17 State Heritage Areas have been designated, as read on 9 October 2026.

What are SA Water augmentation charges?

SA Water describes them as charges that recoup the incremental impact of development on its network. The 2026-27 charges apply to persons receiving SA Water development approval between 1 July 2026 and 30 June 2027 for an additional allotment, a new connection or a variation to an existing connection with more than one new premises in the Greater Adelaide Region, and are paid before SA Water clears titles.

What this analysis
does and does not show.

Evidence note

What it shows: Six official sources a developer reads before buying a residential site in South Australia, what each shows, what each says about its own currency or limits, and its published cost for 2026-27, as read on 9 October 2026.
Key facts quoted: Code Version 2026.19 dated 8 October 2026 in effect; historic versions 2026.1 (15 January 2026) to 2026.17 (10 September 2026); statutory Register Book search fee $36.75 or $45.50, historical search $2.95, GST exempt; Title Watch up to 20 titles; EPA index not exhaustive, updated monthly; EPA Statement 33 questions, $23.00, 8 clear business days; 2,351 State Heritage Places, 17 State Heritage Areas, certified copy $43.75; SA Water map estimations only; 2026-27 augmentation charges for approvals 1 July 2026 to 30 June 2027.
Derived: One count: 17 historic Code versions listed for 2026, our count from the PlanSA page.

PlanSA, the online Code and SA Water pages were read through a rendering proxy on 9 October 2026 because those sites block automated access. We could not open SAPPA itself, and describe it only as PlanSA does.
We did not read the augmentation charge schedules, the SA Water connections policy, the Planning and Design Code text, or the legislation behind any fee or statement.
Other pre-purchase sources exist, including council records and the other government interests in a Form 1. They are not covered here.
We do not assess any site, and nothing here says whether a site is contaminated, heritage-affected, serviceable or developable.
This covers South Australia only.
Nothing here is legal, planning or property advice.
