INSIGHT · AI GOVERNANCE & COMPLIANCE

Construction sign-offs name a person.
The rules we read are silent on AI.

2 November 2026

Can AI sign off construction compliance in Australia? The instruments we read on 2 November 2026 never mention AI. They place each declaration on a named kind of person, among them a registered design practitioner in NSW, an inspecting person in Queensland, a registered practitioner in Victoria, a building surveyor in WA and Tasmania, a certifier in the ACT, a building certifier in the NT. They do not address drafting software, and silence is neither a ban nor a permission. Building Commission NSW's pages do say who may prepare designs and declarations, and they speak of people. The practical question is what record shows what the signing person saw, and when.

Key takeaways

No instrument we read mentions AI: The legislation and regulator pages read on 2 November 2026 for NSW, Queensland, Victoria, WA, Tasmania, the ACT and the NT do not refer to artificial intelligence. We do not read silence as a ban or as approval.
The declaration sits on a named kind of person: WA's Building Act 2011 s 19(3) requires a statement "of the building surveyor signing the certificate". Queensland's Building Regulation 2021 s 53 requires a certificate "signed by the inspecting person".
NSW separates developing a design from declaring it: Building Commission NSW's design obligations page, last updated 8 September 2026, says "you don't have to be registered to develop the designs; only the supervising designer who will sign off on the design compliance declaration needs to be registered". Its classes and roles page says "Design practitioners must be registered to prepare regulated designs and design compliance declarations". Both speak of people, not software, and we did not read the Act.
Some sign-offs turn on an act, not a document: Victoria's Building Act 1993 s 238(2) bars a certificate for building work unless it states the practitioner "has inspected that building work". Queensland's Regulation s 52(2) requires the inspecting person to inspect the stage, although s 52(4) lets them accept and rely on an aspect inspection certificate or QBCC licensee certificate for an aspect, subject to s 52(5). The texts place these steps on the person named and are silent on tools.
We would record what the signer saw, and when: A system-design recommendation, not a legal requirement: the version signed, who or what drafted it, what the signer opened, what they inspected, and the time of each.

Who each instrument places
the declaration on.

The Australian construction sign-offs we read on 2 November 2026 place each declaration on a defined person or business, and none of those instruments addresses AI. In the fifth column, "silent" means the text read says nothing about who or what may prepare a draft.

A row names the instrument's placement of the declaration. It does not answer whether a tool may prepare a draft, which these texts do not address, and it is not a statement of every person's duty under the instrument.

Drafting, declaring and doing
are three separate questions.

A construction sign-off under the instruments read on 2 November 2026 can be split into three questions: who may prepare the words, who declares them, and what the declarer must have done first. The provisions read speak to who declares and what the declarer must have done first, and Queensland's Professional Engineers Act also limits who may carry out engineering services. None mentions AI.

Instrument wording	Source	What the text places on whom
"signed by the inspecting person"	Building Regulation 2021 (Qld) s 53(2)(b)	Places the signature on the inspecting person. Silent on who or what prepares the wording
"the reasons the inspecting person is satisfied"	Building Regulation 2021 (Qld) s 53(2)(c)(i)	Places the stated reasons on the inspecting person. Silent on who or what words them
"the extent to which the inspecting person has relied on"	Building Regulation 2021 (Qld) s 53(2)(c)(ii)	Places on the inspecting person an account of reliance on tests, specifications, rules, standards, codes of practice or other publications. The list does not name software
"has inspected that building work"	Building Act 1993 (Vic) s 238(2)	Bars the practitioner or endorsed engineer from giving a certificate for building work unless it states they have inspected that work
"must inspect the stage"; "in accordance with best industry practice"	Building Regulation 2021 (Qld) s 52(2) and (3)	Places the inspection on the inspecting person, to a stated standard. Under s 52(4) and (5) they may instead accept and rely on an aspect inspection certificate or QBCC licensee certificate for an aspect, with a limit on the final stage of class 1a and class 10 work
"the building surveyor signing the certificate"	Building Act 2011 (WA) s 19(3)	Places the statement on the surveyor signing. For a building permit, s 20(1)(d) requires that surveyor to be entitled to sign and independent
"A person who is not a practising professional engineer must not carry out professional engineering services"	Professional Engineers Act 2002 (Qld) s 115(1), with a direct supervision exception in s 115(2)	Places the services on a practising professional engineer, or a person the engineer directs, oversees and evaluates and who works under that engineer's responsibility (s 115(2), (5)). The text speaks of a person and does not mention software

AI code checks, contract review
and the person the text still names.

AI building code checks and AI contract review are not addressed by the instruments we read on 2 November 2026. A tool can produce a findings list or a clause summary, and the text still places any resulting declaration or response on the person or party it names.

A contract may add its own sign-offs, such as a superintendent's certificate under a standard form. Those are contract terms, not statute, and we did not read any standard form text. Check the contract in front of you.

AI use	What it produces	Who the text still names	Label
Reading drawings against building rules	A draft list of possible issues, with sheet references	The designer or surveyor who declares or certifies, as in the table above	Our design. Our page on AI reading drawings covers published accuracy limits
Drafting a certificate or inspection report	Pre-filled fields and wording	The person who signs. In Queensland, s 40 of the Regulation also bars a competent person giving the certifier a document they know or reasonably suspect is false or misleading in a material particular	Our design; the s 40 duty is required by the Regulation
Contract review	Clause summary and a list of questions	The party to the contract and its adviser. No instrument read addresses this use	Our design
Drafting a payment schedule	Draft amount and reasons	The respondent (BIF Act 2017 (Qld) s 76)	Required by (the schedule); the draft step is our design
A human in the loop policy	A written rule on who reviews what	National AI Centre Foundations: "mandatory human review for high-stakes decisions"	Suggested by guidance

The record:
what the signing person saw, and when.

The instruments read on 2 November 2026 fix the certificate and rarely the working record behind it.

Field	What it holds	Why it matters	Label
Sign-off and instrument	Which certificate, under which section, for which stage	Sets who may sign and what must be stated	Our design
Signer and authority	Name, role, registration or licence reference, as checked on the day	The instruments tie the sign-off to a kind of person	Our design, supporting the instrument's placement
Reasons and reliance	The stated reasons and the publications relied on	Queensland requires these on the certificate	Required by s 53(2)(c) of the Regulation (Qld certificate of inspection)
Competent person decision	The certifier's record of the decision	Queensland requires the certifier to keep it for at least 7 years (s 36(2))	Required by s 36 of the Regulation (Qld)
Inspection event	Date, time, place, what was inspected, by whom, with photos	Where the text turns on an inspection, this is the evidence it happened	Our design, supporting s 238(2) (Vic) and s 52 (Qld)
Drafter	Who or what prepared the draft: person, tool and version	Separates drafting from declaring	Our design
Draft as produced	The unedited draft, with time	Shows what the person changed	Our design

What we would put in a system

A system-design recommendation for a business that uses AI to prepare sign-off paperwork.

Where agents help here is narrow. An agent can pre-fill a form, list the documents behind it and flag what is missing, and the named person confirms or rejects it. In this design, no agent decides that work complies, makes a declaration, or signs. Our page on how we deploy AI sets out our general approach.

Field	Why it is load-bearing
A hard stop before signature	The signing person's action should be a separate recorded step, never a side effect of generating a document.
Signer's own credentials, not a shared login	A shared account cannot show which person made the declaration.
Version lock at signing	A later edit should create a new version, so the signed text stays fixed.
An inspection event linked to the certificate	Where a text turns on an inspection, the certificate should point to it.

Questions worth asking
of your own sign-offs

For a registered practitioner: on your last declaration, can you show what you opened before signing?

The NSW, Queensland, Victorian, WA, Tasmanian, ACT and NT texts we read place the declaration on the person who makes it. Keeping the document versions and times opened is our design suggestion. General information as read on 2 November 2026, not legal advice.

For a Queensland certifier: when a tool helps word a certificate of inspection, are the reasons still your own?

Section 53(2)(c) of the Building Regulation 2021 requires the certificate to state the reasons the inspecting person is satisfied. The section is silent on tools. General information as read on 2 November 2026, not legal advice.

For a builder's project manager: who in your business can press the final send on a payment schedule?

Section 76 of the BIF Act 2017 (Qld) places the response on the respondent, with a 15 business day outer limit unless the contract period is shorter. Who approves the draft inside the business is a choice to record. General information as read on 2 November 2026, not legal advice.

For a principal engineer: does your tool's output count as work you directly supervised?

Section 115 of the Professional Engineers Act 2002 (Qld) speaks of a person carrying out services under direct supervision, and does not mention software. How it applies to a tool is not determined here. Ask your adviser or the board. General information as read on 2 November 2026, not legal advice.

Questions people ask
about AI and construction sign-offs

Can AI sign off building code compliance in Australia?

The NSW, Queensland, Victorian, WA, Tasmanian, ACT and NT instruments we read on 2 November 2026 do not mention AI. They place each declaration on a named kind of person, such as a building surveyor in WA or an inspecting person in Queensland. None describes a tool making the declaration. South Australia was not verified.

Is AI banned in construction certification?

No instrument we read on 2 November 2026 bans AI or approves it. The texts for NSW, Queensland, Victoria, WA, Tasmania, the ACT and the NT are silent on AI. Silence does not move a declaration: the text still places it on the person it names, and some sign-offs turn on an inspection.

Can an AI tool draft a design compliance declaration in NSW?

Building Commission NSW's pages do not address AI or software. Its design obligations page, last updated 8 September 2026, says only the person signing off and declaring the design needs to register, and that you do not have to be registered to develop the designs. Its classes and roles page, last updated 29 October 2026, says design practitioners must be registered to prepare regulated designs and design compliance declarations. We did not read the Design and Building Practitioners Act, so the position of a tool is not determined here.

What must a Queensland certificate of inspection state?

Under s 53(2) of the Building Regulation 2021 (Qld), current from 14 August 2026, the certificate is in the approved form, signed by the inspecting person, and states the reasons they are satisfied and the extent to which they relied on tests, specifications, rules, standards, codes of practice or other publications.

What is a human in the loop policy for a construction business?

A human in the loop policy says which AI outputs a named person must review before they are used. The National AI Centre's Foundations guidance calls for mandatory human review for high-stakes decisions and for human override points. It is voluntary guidance. Each statutory sign-off still follows its own instrument.

Can AI review a construction contract?

A tool can summarise clauses, and no instrument we read on 2 November 2026 addresses that use. The parties remain bound by the contract, and a respondent must still give any payment schedule the security of payment law requires. A summary is not legal advice. General information only.

What this analysis
does and does not show.

Evidence note

What it shows: Who the NSW, Queensland, Victorian, WA, Tasmanian, ACT and NT sources read on 2 November 2026 name for a set of construction sign-offs, what each says is declared, that those texts are silent on AI, and a record design with each field labelled as required by, suggested by guidance or our design.
Key facts quoted: Qld Building Regulation 2021 s 53(2): "signed by the inspecting person"; Vic Building Act 1993 s 238(2): "has inspected that building work"; WA Building Act 2011 s 19(3): "the building surveyor signing the certificate"; Building Commission NSW: "only the supervising designer who will sign off on the design compliance declaration needs to be registered"; Tas Building Act 2016 s 152(1): "in so far as it is reasonably practicable to inspect"; ACT Building Act 2004 s 44(1): "must inspect the building work as soon as practicable"; NT Building Act 1993 s 69(2): "natural person"; BIF Act 2017 (Qld) s 76: 15 business days.

NSW Acts were not read. The NSW legislation register blocks automated access, so NSW rows rest on Building Commission NSW's pages, which summarise the law.
South Australia's Statement of Compliance sources blocked direct reading on 2 November 2026. That row is not verified, and no inference is drawn from it.
The Tasmanian, ACT and NT Acts read were searched whole on 2 November 2026 for "artificial intelligence", "AI", "machine learning", "automated", "automation", "algorithm", "software" and "computer". The only match was "computer database", for the registers the Administrator keeps, in s 50(1) of Tasmania's Occupational Licensing Act 2005.
Silence is limited to the sections and pages read. Regulations, practice notes and codes we did not read may say more. That includes Victoria's prescribing regulations, WA's regulations under s 19(6), the Qld Electrical Safety Regulation 2013, Tasmania's regulations, guidelines and approved forms under the Building Act 2016 and Occupational Licensing Act 2005, the ACT's regulation, approved forms and Construction Occupations (Licensing) Act 2004, and the NT's Building Regulations 1993 and approved forms. Those may add a step or a signature.
State electronic transactions Acts were not read. Section 10 of the Commonwealth Act covers requirements under Commonwealth law only.
No standard form contract and no Australian Standard text was read or quoted.
The table is not a complete list of sign-offs.
General information, not legal, certification or WHS advice. Nothing here says a tool may or may not be used for any task, or that a given certificate is valid.

What to watch next

We found no publisher-announced date for an AI-specific sign-off rule in the instruments read.

10 December 2026: APP 1.7 to 1.9 commence for privacy policies. Our page on the AI audit trail covers what that means for records.
Late 2026: SafeWork NSW Stage 2: SafeWork NSW says further targeted consultation on the digital work systems guidelines will occur in late 2026. The remaining provisions commence on a date or dates to be announced.
