ACT Residential Building Framework: Licensing, Contracts and Insurance

What it is

Residential building in the Australian Capital Territory runs off two Acts. The Building Act 2004 (ACT), A2004-11, carries the statutory warranties, the residential building insurance and the standard conditions power. The Construction Occupations (Licensing) Act 2004 (ACT), A2004-12, licenses the people who do the work. Access Canberra administers both through the Construction Occupations Registrar. The ACT Civil and Administrative Tribunal (ACAT) hears disputes.

The surprise for anyone arriving from NSW or Victoria is how little the ACT puts inside the contract itself. It regulates the licence, the warranty and the insurance hard. The document, the deposit, the payment schedule, the variations and any cooling-off are left almost entirely to the parties. Several rules that eastern-state builders assume exist simply do not exist here.

Licensing under the Construction Occupations (Licensing) Act 2004

Anyone who provides a construction service in the ACT for reward must hold a construction occupation licence in the right class. For builders there are five licence classes, and the class letter decides what may be built.

• Class A, unlimited, any height and any Building Code of Australia class of building other than specialist work
• Class B, buildings of three storeys or lower, plus basic building work
• Class C, low-rise residential, class 1, 2 or 10a buildings of two storeys or lower, plus basic building work
• Class D, non-structural basic building work only
• Owner-builder, class 1, 2 or 10 work on the licensee's own home

Scope for each class is set by declaration rather than in the Act, so the classes can move without the Act being amended. Class A, B and C applicants sit a written examination set by the Registrar with an 80 per cent pass mark. A company or partnership needs its own licence and a nominee who holds an individual licence in the same class. The Registrar can order a licensee, a former licensee or a company director to rectify building work for up to 10 years after completion, even where the company has been deregistered.

What the Building Act 2004 puts inside the contract

Part 6 of the Building Act 2004 is the operative part for residential building work. It switches on at a cost of $12,000 or more. Section 87(c) turns Part 6 off below a prescribed amount, and section 37 of the Building (General) Regulation 2008 (ACT) sets that amount at $12,000. Below $12,000 there is no statutory warranty and no compulsory insurance.

What Part 6 does not do is prescribe the content of the contract. Division 6.2A reads like a mandatory contents regime but it has never been switched on.

• Section 89C(1) lets a regulation prescribe a standard condition, and section 89C(2) makes entering a contract that omits one a strict liability offence of up to 10 penalty units.
• Section 89D(1) lets a regulation prescribe documents that must be attached, with the same penalty.
• Section 89E(1) lets a regulation prescribe a prohibited condition, and section 89E(2) makes it void.

The Building (General) Regulation 2008 has prescribed no standard condition and no required document. Only the prohibited-condition limb is live: section 38B voids a clause that lets anyone but the landowner appoint or remove the certifier for certain class 1 and class 2 work. The offences in sections 89C(2) and 89D(2) have nothing to bite on.

No writing rule, no deposit cap, no cooling-off, no stage schedule

Four rules eastern-state builders expect are absent in the ACT, and each is a real gap rather than a detail to check.

• No requirement that the contract be in writing. Section 89B defines a residential building work contract without requiring it to be written. ACT Government guidance recommends a written contract and lists what to include, but that is advice, not a statutory duty. The builder must give the owner evidence of the insurance, not a copy of the contract.
• No statutory deposit cap. The word deposit appears in one section of the Building Act 2004, section 93, which is about insurance payouts rather than limits. There is no percentage cap and no dollar ceiling. The only hard number is that section 93(3) and section 43 of the Building (General) Regulation 2008 limit what an owner can recover on a lost deposit to $10,000. Anything above $10,000 is unsecured if the builder fails before starting.
• No cooling-off period. The word cooling does not appear in the Building Act 2004. The well known 5 working day cooling-off right sits in the Civil Law (Sale of Residential Property) Act 2003 (ACT) and applies to buying residential property, not to a contract to build. Once an ACT building contract is signed, exit is governed by the contract and the general law.
• No mandatory progress payment stages and no statutory variations regime. Part 6 prescribes no stage table and no percentage caps. The Building Act 2004 does not legislate variations at all, so there is no writing rule, no notice rule and no bar on recovery. The Building and Construction Industry (Security of Payment) Act 2009 (ACT) carves out a resident owner, so the rapid adjudication remedy is closed to owner-occupiers. In each case the contract is the only schedule the owner gets.

Statutory warranties under section 88

Section 88(1) of the Building Act 2004 implies warranties into every contract to carry out residential building work to which the builder is a party, whether or not they are written in. The builder warrants compliance with the Act, proper and skilful work to the approved plans, good and proper materials, reasonable promptness where no date is stated and fitness for a purpose the owner has made known.

Section 88(3) passes the warranty to successors in title. Section 88(4) and section 38 of the Building (General) Regulation 2008 end it 6 years after completion day for a structural element and 2 years for a non-structural element. Section 91(3) makes void any provision that negatives, limits or modifies the operation of Part 6.

Residential building insurance

The Building Act 2004 requires the builder to hold residential building insurance for residential work of $12,000 or more on buildings of three storeys or below, not counting a car park, before applying to the certifier for a building commencement notice. Cover is either a policy from an authorised insurer under section 90, or a fidelity certificate from an approved fidelity fund scheme. QBE Insurance is currently the only authorised insurer and the Master Builders Fidelity Fund is currently the only approved fidelity fund scheme.

From 1 January 2025 the minimum cover is $200,000, up from $85,000, and the claim window is 180 days, up from 90 days. The triggers are narrow. The insurance responds only where the builder becomes insolvent, dies or disappears. A cancelled licence is not a trigger, and the cover does not respond because the builder is slow, argumentative or refusing to return. The certifier must confirm the cover is in place before issuing a building commencement notice, so no cover means the work cannot lawfully start. The cover follows the building to a future owner. Work done by a licensed owner-builder does not attract the warranty or the insurance, which leaves a buyer of an owner-built home with neither protection.

ACAT and rectification

ACAT hears residential building disputes under the Building Act 2004 and reviews decisions of the Construction Occupations Registrar. Its civil claims jurisdiction runs up to $25,000. Larger contract or defect claims go to the ACT Magistrates Court or Supreme Court. Access Canberra, through the Registrar, can also issue rectification orders under the Construction Occupations (Licensing) Act 2004 for up to 10 years after completion. Owners typically raise the matter with Access Canberra first, then escalate to ACAT for binding orders.

Why it matters for ACT builders

Every residential job of $12,000 or more in the ACT needs a current licence in the right class, residential building insurance handed to the owner before any building commencement notice and clean records that survive the section 88 warranty period. What it does not need, and what an ACT builder should never promise an owner it has, is a statutory deposit cap, a cooling-off period, a mandatory stage-payment schedule or a statutory variations regime. None of those exist in the Territory. The protection an ACT owner gets is the licence, the warranty and the insurance, plus whatever the contract itself is drafted to add.
