How Defect Rectification Works in ACT Residential Building

What it is

Defect rectification in the Australian Capital Territory runs through Access Canberra, the Construction Occupations Registrar and ACAT. Access Canberra handles compliance complaints and can issue rectification orders against licensed builders under the Construction Occupations (Licensing) Act 2004 (ACT). ACAT handles section 88 statutory warranty claims and reviews of Access Canberra decisions.

The Property Developers Act 2024 (ACT) added a separate rectification-order framework for developer-controlled residential projects. Rectification orders under that Act commenced 11 July 2024 and operate alongside the older Access Canberra pathway.

The Access Canberra complaint

An owner with a defect complaint against a licensed builder starts with Access Canberra. The complaint identifies the builder, the work and the defect. Access Canberra assigns an investigator and typically arranges a site inspection for technical defects.

Where Access Canberra confirms a defect and finds a breach of the licensee's obligations, it can issue a rectification order under the Construction Occupations (Licensing) Act 2004 (ACT). The order specifies the defective work, the required rectification and the timeframe. Non-compliance is a licensing offence and grounds for suspension or cancellation.

Section 88 as the substantive obligation

The five statutory warranties under section 88 of the Building Act 2004 (ACT) are the substantive obligation. They attach to every residential building work contract of $12,000 or more that requires building approval. The warranties run for 6 years for structural elements and 2 years for non-structural work, both from completion, and any contract term purporting to restrict them is of no effect.

Enforcement of a section 88 warranty is through ACAT, not through Access Canberra. Access Canberra deals with compliance breaches at the licensing layer. ACAT deals with the money claim between owner and builder.

Builder's right to inspect and re-enter

The Building Act 2004 (ACT) does not carry a statutory right of re-entry to rectify. The right sits in the contract. Most ACT industry templates give the builder a reasonable access right during the defects liability period to inspect and make good notified defects.

Under Access Canberra guidance, an owner who refuses reasonable access after a rectification order is issued may have the order narrowed or rescinded and may lose the ability to recover the rectification cost from the builder for that work.

Rectification timeframes

Section 88 does not fix a rectification timeframe. Access Canberra rectification orders set the timeframe on a case-by-case basis, typically 30 to 90 days depending on defect complexity. ACAT can set a longer or shorter period in a section 88 order.

The defects liability period in the contract is the practical starting point. A typical ACT contract runs a 3 to 6 month DLP after completion, during which the builder must attend to notified defects at its own cost. That contractual DLP is separate from and shorter than the statutory warranty periods.

Property Developers Act 2024 rectification orders

The Property Developers Act 2024 (ACT) added a rectification-order framework for developer-controlled residential projects. Rectification orders under Part 3 of that Act commenced 11 July 2024. The framework applies to class 2 residential apartment buildings and similar developer-controlled work, with an emphasis on serious defects.

Rectification orders under the Property Developers Act can be made against the developer even after the developer has sold the units, and can require the developer to complete rectification work at its own cost. Enforcement is through ACAT.

Escalation to ACAT

Where Access Canberra investigation fails or the owner wants a money order, the matter goes to ACAT under its building and construction jurisdiction. ACAT can award money damages, order rectification, order specific performance and award costs.

ACAT is also the venue for a section 88 warranty claim by the original owner or a successor in title.

Insurance response

Residential building insurance or a fidelity certificate is required for residential building work of $12,000 or more on buildings up to 3 storeys. Two routes: a policy from an authorised insurer (currently only QBE) or a fidelity certificate from an approved scheme (currently only the Master Builders Fidelity Fund). Minimum cover $200,000 (raised from $85,000 on 1 January 2025), claim window 180 days (raised from 90). Cover triggers: builder insolvency, death, disappearance.

How the ACT compares

The ACT's Access Canberra investigation and rectification-order pathway is closer to the WA Building and Energy remedy order model than to the tribunal-first structure in NSW. The Property Developers Act 2024 adds a developer-focused layer that no other Australian jurisdiction runs in the same form, giving the ACT a distinctive framework for class 2 residential work.
