How to make a building complaint in the ACT — Access Canberra and ACAT explained

If you are a homeowner in the Australian Capital Territory with a building dispute — defects your builder won’t fix, incomplete work, or disagreements about the quality of what was built — Access Canberra is the ACT Government’s building regulatory body, and the ACT Civil and Administrative Tribunal (ACAT) is the primary forum for resolving residential building disputes.

The legislative framework in the ACT

Building work in the ACT is regulated by the Building Act 2004 (ACT) and the Construction Occupations (Licensing) Act 2004. These set out the licensing requirements for builders and the warranty obligations for residential building work.

The ACT’s statutory warranty framework for residential building work:

• Residential building warranty (structural defects): 6 years from the date of practical completion
• Residential building warranty (non-structural defects): 1 year from the date of practical completion
• These apply to licensed residential building contractors in the ACT

The ACT also has specific rules requiring builders to maintain building indemnity insurance for residential work above prescribed thresholds. This provides a level of consumer protection if a builder becomes insolvent or disappears.

Step 1: Attempt direct resolution

Before approaching Access Canberra or ACAT, you must make a genuine effort to resolve the matter with your builder:

1. Serve a written defect notice — specify each defect with clear descriptions and attach photographs. Keep copies of everything
2. Allow a reasonable response time — your contract will specify a timeframe; in the absence of a contractual period, 14 days is a reasonable starting point
3. Confirm rectification scope — if the builder acknowledges the defects, confirm in writing what they will fix and by when
4. Follow up in writing if rectification does not proceed as agreed

Document every interaction. You will need this record if you proceed to Access Canberra or ACAT.

Step 2: Contact Access Canberra

Access Canberra regulates building licences in the ACT and handles complaints about licensed building contractors.

Access Canberra can:

• Investigate complaints about licensed builders regarding workmanship and contract compliance
• Take disciplinary action against licensed contractors (suspension, cancellation, conditions on licence)
• Refer disputes to mediation
• Advise on your rights under the Building Act 2004

How to contact Access Canberra:

• Online through the Access Canberra website (search “Access Canberra building complaint”)
• In person at an Access Canberra service centre in Canberra
• By phone through the ACT Government general enquiries line

Your complaint to Access Canberra should include:

• The builder’s name and licence number (verifiable on the Access Canberra licence register)
• A description of the building work and the nature of the dispute
• Supporting documents (contract, defect notices, photographs, correspondence)
• What resolution you are seeking

Access Canberra investigation can result in licensing action against a builder if non-compliant work is confirmed, but it does not directly order the builder to compensate you. For that, you need ACAT.

Step 3: Apply to ACAT

The ACT Civil and Administrative Tribunal (ACAT) is the primary independent dispute resolution body for building disputes in the ACT. ACAT can hear disputes between homeowners and building contractors about:

• Whether work was completed in accordance with the contract
• Whether defects are present and whether they require rectification
• Compensation for losses arising from defective or incomplete building work
• Payment disputes between builders and homeowners

ACAT has jurisdiction under the Civil Law (Wrongs) Act 2002, the ACT Consumer Protection Act, and the Building Act 2004 for building-related matters. ACAT proceedings are designed to be accessible without legal representation, though many parties choose to have a lawyer or building consultant assist them.

How to apply to ACAT

Applications to ACAT are made through the ACAT website or in writing to the ACAT registry. Filing fees apply and vary by the amount in dispute.

Your ACAT application should include:

• A concise statement of facts describing the dispute
• The orders you are seeking (e.g., rectification of defects, compensation for losses)
• Copies of all supporting documents
• An independent building inspection report is not mandatory but is highly recommended for defect claims

ACAT typically conducts a preliminary conference between the parties to explore settlement before listing a hearing. Many disputes resolve at this conference stage.

For disputes involving significant defects or large amounts of money, engaging a construction lawyer before the hearing is advisable.

ACT building indemnity insurance

In the ACT, residential builders must hold building indemnity insurance for residential construction work above a prescribed threshold. This insurance protects homeowners if the builder:

• Dies or disappears
• Becomes insolvent

Building indemnity insurance in the ACT provides cover for the cost of completing or rectifying building work in these circumstances. It is not a protection against defects during an active build where the builder is still trading.

Confirm that your builder holds building indemnity insurance before commencing work. The insurance certificate of currency should be provided to you before your deposit is paid.

Specific ACT considerations

Long-term lease system

The ACT operates under a long-term lease (land-tenure) system rather than freehold ownership. While this does not directly affect your rights against your builder, it is relevant to any building dispute that affects the land or involves remediation works requiring development approval.

Body corporate disputes in units

For strata (units) title defects in the ACT, disputes about common property defects involve the body corporate (owners corporation) as well as individual owners. The ACT Unit Titles Act 2001 and Unit Titles (Management) Act 2011 govern these situations. ACAT also handles unit title disputes.

Commonwealth involvement

For building work within Commonwealth Government property or involving Commonwealth tenants, different rules may apply. Most private residential construction in the ACT follows the state-equivalent framework described above.

Evidence checklist for an ACT building complaint

• Signed building contract and all specifications/inclusions schedules
• All signed variation orders
• Record of all payments made (receipts, bank statements)
• All written correspondence with your builder (emails, letters, texts)
• Copies of every written defect notice you served and the builder’s responses
• Dated photographs of all defects (use Checka for timestamped, location-tagged photos)
• An independent building inspection report (highly recommended)
• Your builder’s licence number and evidence of indemnity insurance

• For a binding determination or compensation, apply to ACAT (ACT Civil and Administrative Tribunal) — it is designed to be accessible without a lawyer, though legal advice helps for complex disputes
• ACT builders must hold building indemnity insurance for residential work — confirm this is in place before paying your deposit
• Prepare a comprehensive evidence file including independent expert reports before approaching Access Canberra or ACAT; the strength of your evidence determines the outcome
