When You Need a Builder Licence in the ACT

What it is

The Australian Capital Territory licenses builders under the Construction Occupations (Licensing) Act 2004 (ACT). The Construction Occupations Registrar within Access Canberra is the licensing authority. The Act licences the person and the class of work: a person carrying out or arranging construction occupations work in a licensable class needs a licence.

The Building Act 2004 (ACT) runs the parallel framework for building approvals, statutory warranties (section 88) and residential building insurance (Part 6). Statutory warranties and insurance apply to residential building work of $12,000 or more.

The licence trigger

Section 12 of the Construction Occupations (Licensing) Act 2004 (ACT) makes it an offence to carry out, arrange or offer to carry out construction occupations work in a licensable class without a licence. The Act uses licensable classes rather than a dollar threshold: a person doing residential building work in a licensable class needs the appropriate licence at any contract value.

That is different from NSW ($5,000), VIC ($10,000), QLD ($3,300) and WA ($20,000 permit work), which use dollar thresholds. It is closer to SA (business-of-contracting) and TAS (class-based) in structure.

Licence classes

Construction occupations covered by the Act include:

• builder classes A, B and C (residential capacity by dwelling size)
• building surveyor and building assessor
• construction manager
• specialist trade licences (electrical, plumbing, drainage, gas-fitting under separate legislation)

Class A builder is the highest residential category, permitted to work on class 1 and class 10 buildings of any size. Class B is restricted to smaller buildings. Class C is the entry class for limited work.

Each class has qualification, experience and financial requirements. A company builder must have a nominee licensed in the relevant class.

The $12,000 threshold for warranties and insurance

Statutory warranties under section 88 of the Building Act 2004 (ACT) apply to residential building work of $12,000 or more that requires building approval. Residential building insurance under sections 90 and 91 attaches at the same threshold.

Below $12,000 statutory warranties and insurance do not apply, but the licence requirement still does for licensable classes. That splits the ACT framework into a licensing layer (any value) and a warranty/insurance layer ($12,000 upwards).

Nominee licensing

A company or partnership holding a builder licence in the ACT must have a nominee who holds an individual licence in the same class. The nominee is responsible for the technical work and must comply with the class-specific competencies and CPD requirements.

The Construction Occupations Registrar can require a change of nominee where the current nominee is unfit or unavailable. Section 22(3) of the COL Regulation requires the licensee to notify the Registrar within 1 business day of any change in nominee or director.

Owner-builder framework

Owner-builder work in the ACT does not require a builder licence but does require Access Canberra approval before work starts. Owner-builders take out the equivalent residential building insurance (or fidelity certificate) themselves rather than through a licensed builder.

Owner-builders carry personal responsibility for defects and cannot on-sell the work as a licensed service. Restrictions on sale within a set period apply, with disclosure required to any subsequent purchaser.

The Property Developers Act 2024 layer

The Property Developers Act 2024 (ACT) added a separate developer licensing framework for class 2 residential apartment buildings. Developer licensing under that Act runs alongside the builder licence framework and applies to the developer entity rather than the builder.

Rectification orders under the Property Developers Act 2024 commenced 11 July 2024 and developer licensing commences by 10 July 2026 (with mandatory licensing reported from 1 October 2026, though sources differ).

Consequences of unlicensed work

Section 12 of the COL Act 2004 is the offence provision, carrying penalty units. Unlicensed practice can also affect contract enforceability under general illegality principles.

Access Canberra can take separate disciplinary action, including licence conditions, suspension or cancellation for a licensee whose business has been associated with unlicensed practice.

How the ACT compares

The ACT's class-based licensing at any value is closer to SA and TAS than to the dollar-threshold jurisdictions. The $12,000 warranty and insurance threshold sits between VIC's $10,000 major domestic building contract threshold and WA's $20,000 registration threshold.

The Property Developers Act 2024 developer licensing framework is unique in Australia and reflects ACT-specific post-Grenfell class 2 reforms. TradeForm ACT templates flag both the builder licence framework and the developer licence framework where relevant.
