Practical completion is the point the work reaches, and handover is the handing over that follows it: South Australia’s consumer guide says the builder “will hand-over your home when it is built to a point of practical completion”. A particular contract sets the sequence. This note quotes that guide and the Housing Industry Association’s summary of its own contracts, and keeps the regulatory documents separate.
What does practical completion mean?
In South Australia, the clearest public wording this note found is in the January 2025 consumer guide from Consumer and Business Services (CBS). It describes the point of practical completion as “when your house is complete except for any minor omissions or defects which do not prevent it from being used for its intended purpose”. That is guidance in a consumer guide, read as an Internet Archive copy. It is not a statutory definition, and the contract’s own wording is what to read for a particular job.
Contract wording can differ. The Housing Industry Association (HIA) states that under its SA New Homes, Alteration & Additions, Cost Plus, and Kit & Transportable Homes contracts, Practical Completion means “when the work is substantially complete and reasonably fit for use”. That is a trade association’s summary of its own contracts, written for builders, in an article dated 31 August 2023. The contracts themselves were not read for this note, the article predates South Australian changes recorded from 10 November 2025, and HIA says the content “should not be relied upon as such”. It is not a statement of South Australian law, and another contract can use other words.
HIA adds that practical completion “does not require completion without any defects”. It gives incomplete skirting, uneven paint finishes or a missing robe rail as examples that would not ordinarily stop a home being used, and incomplete work such as a missing oven or sink, untiled showers, or electrical supply and water services as examples likely to make the works unfit for use.
Other states show related wording, quoted only for comparison. The Queensland Building and Construction Commission says on its website: “The licensed contractor has completed all work according to the contract, plans and specifications. If there are any defects or omissions, they should only be minor. The work must be reasonably suitable for habitation and comply with all relevant statutory requirements, including the Building Code of Australia.” Section 45(6) of Victoria’s Domestic Building Contracts Act 1995, in its section on referring domestic building work disputes, defines the date of practical completion as the date when the work “is completed except for any omissions or defects that do not prevent the domestic building work from being reasonably capable of being used for its intended purpose”.
Does South Australian law define practical completion?
This note did not find a South Australian statutory definition, and it does not say that none exists.
The words practical completion do not appear in a copy of the Building Work Contractors Act 1995 (SA) consolidated to 1 January 2024, held by the Internet Archive, or in the prescribed Form 1 notice in its September 2024 version. The Law Handbook’s page on building work contracts, published by the Legal Services Commission of South Australia, does not define the term either. The current Act, the Building Work Contractors Regulations 2026 (SA) and the current Form 1 could not be read.
The reader’s own contract is therefore the document to read on what practical completion means for that job, how it is notified and what follows it. If the contract does not define the term, that is a point for legal advice.
Is practical completion the same as handover?
They are different things. Practical completion is the point the work reaches, and handover is when the builder gives the owner possession of the home. CBS links them: the builder “will hand-over your home when it is built to a point of practical completion”, and the final payment, “outlined in the contract, should only be made when practical completion occurs and hand-over is ready”. Whether they fall on one day on a particular job is for that contract.
HIA describes one sequence, for its own contracts. When the work reaches practical completion, the builder gives the owner a final account. Within 7 days of receiving it, HIA says the owner must inspect the works with the builder, write anything defective or incomplete in a Certificate of Practical Completion, sign it and give it to the builder, and pay the final account “in full by cash or bank cheque, with no deduction or set off”. HIA states that the builder “is not required to hand over the home until the practical completion process has been followed, including payment of the final account in full and provision of the Certificate of Practical Completion”.
That is HIA’s summary, not a statement of South Australian law. The Law Handbook summarises section 30 of the Building Work Contractors Act 1995 (SA) as covering genuine progress payments for work already performed and authorised advance payments, and an archived 2024 copy also lists an entitlement under the Security of Payment Act 2009. The Handbook records that a contract cannot exclude the effect of the Act (section 42); and that a party may apply to the Magistrates Court for relief from harsh or unconscionable terms (section 38). How those provisions bear on a final account under a particular contract is a question for legal advice.
HIA also describes a change of responsibility at handover: the builder retains possession and insures the work until the handover date, and the owner insures it afterwards.
Is practical completion the same as an occupation certificate?
No, they are different kinds of thing: practical completion is a contract matter, and a certificate of occupancy is a regulatory document. Certificate of occupancy is the South Australian term in the Planning, Development and Infrastructure Act 2016, and the note on that certificate sets out when one is required for a house, which turns on dates.
The note on the Statement of Compliance covers another document at the end of a build, given with the notice of completion under regulation 104. Neither is the contract’s practical completion, although a contract could refer to them.
Whether a contract links practical completion, final payment or handover to one of these documents is for that contract to say. A statute can draw such a link. For major domestic building contracts in Victoria, section 42 bars a builder from demanding final payment until the work is completed in accordance with the contract’s plans and specifications and the owner is given a copy of the occupancy permit if the building permit requires one, or otherwise the certificate of final inspection. This note did not find a South Australian statutory equivalent in what it could read.
What is the practical completion date, and what does it affect?
How the practical completion date is worked out, and who decides it, is for the contract to say. The CBS guide and HIA’s article do not address it. Under the contracts HIA describes, reaching practical completion starts the final account and the inspection, and handover follows.
The Law Handbook records time limits for claims that run from “completion of the building work”, for statutory warranties under section 32 of the Building Work Contractors Act and for defective work under section 159 of the Planning, Development and Infrastructure Act. It does not say that this phrase means the practical completion date, and this note does not answer that. It is a question for legal advice.
What happens to defects after practical completion?
Under the contracts HIA describes, the builder need not fix every item before handover, and is to fix the items listed in the Certificate of Practical Completion “within a reasonable time after hand-over”, with the owner giving reasonable access.
The length of any defects liability period and how items are reported during it are matters to read in the contract. Separately, the Law Handbook records that section 32 of the Building Work Contractors Act 1995 (SA) implies certain statutory warranties into every domestic building work contract, and that a contract cannot exclude the effect of the Act. The note on statutory warranties covers these, and the handover note covers how to record items.
This note is general information, not legal advice. The Law Handbook says its own content “should not be relied upon as a substitute for legal advice”.
Common Questions
Is practical completion the same as handover?
They are different things. The January 2025 consumer guide from South Australia’s Consumer and Business Services says the builder will hand over the home when it is built to a point of practical completion, so practical completion is the point the work reaches and handover is when the builder gives the owner possession of the home. In HIA’s 2023 summary of its South Australian contracts, reaching practical completion starts a process of joint inspection, a signed Certificate of Practical Completion and the final account paid in full, and handover follows. Another contract may set a different sequence, so that contract’s wording is the one to read.
What does practical completion mean in South Australia?
The January 2025 consumer guide from Consumer and Business Services describes it as when the house is complete except for any minor omissions or defects which do not prevent it from being used for its intended purpose. That is consumer guidance. This note found no South Australian statutory definition, in the Law Handbook or in a copy of the Building Work Contractors Act 1995 (SA) consolidated to 1 January 2024, but it could not read the current Act or the Regulations 2026. A particular contract may define the term in its own words, and that wording is the one to read.
Is practical completion the same as a certificate of occupancy in SA?
No. Practical completion is a contract term, so its meaning is read in the building contract, while a certificate of occupancy is a document under section 152 of the Planning, Development and Infrastructure Act 2016 (SA). Whether a particular house needs one turns on dates in the Regulations, as the certificate of occupancy note sets out, and the council or certifier confirms it. A contract may or may not link the two.
Can there be defects at practical completion?
The January 2025 consumer guide from South Australia’s Consumer and Business Services describes practical completion as complete except for any minor omissions or defects which do not prevent the house from being used for its intended purpose. A particular contract’s wording may differ. Separately, the Law Handbook records that section 32 of the Building Work Contractors Act 1995 (SA) implies certain statutory warranties into every domestic building work contract.
When is the final payment made on a new house in SA?
The January 2025 consumer guide from Consumer and Business Services says the final payment, outlined in the contract, should only be made when practical completion occurs and hand-over is ready. HIA’s 2023 summary of its own contracts describes the final account being paid within a process before handover. That summary is not a statement of South Australian law. The Law Handbook records that section 30 of the Building Work Contractors Act 1995 (SA) covers genuine progress payments for work already performed and authorised advance payments; an archived 2024 copy of the Act also lists an entitlement under the Security of Payment Act 2009, and an archived 2011 copy of that Act excludes domestic building work on the part of premises where the party for whom the work is carried out resides or proposes to reside. Current versions were not read. A dispute about a particular final account calls for advice on the contract and the Act.
What is the practical completion date?
This note found no South Australian source that fixes the practical completion date, so the building contract is the place to find how it is worked out. Section 45(6) of Victoria’s Domestic Building Contracts Act 1995 defines the date only for referring domestic building work disputes in Victoria. Whether the date starts any statutory time limit in South Australia is a question for legal advice.
