Mistakes, Disputes and Official Sources
Consumer guarantees and statutory warranties for renovations in Australia
How the Australian Consumer Law guarantees and state statutory warranties protect homeowners on renovation work, the time limits in NSW, Victoria and Queensland, and how to use them.
Two layers of law protect you on renovation work, whatever the contract says. The Australian Consumer Law (ACL) guarantees that services you buy as a consumer are supplied with due care and skill, are fit for any purpose you made known, and are supplied within a reasonable time if no time was agreed; products such as appliances and fittings carry their own guarantees. On top of that, state building laws imply statutory warranties into home building contracts, for example that work is done in a proper and workmanlike manner, with suitable materials, in line with the law and the plans, and with reasonable diligence. These cannot be contracted out of. Time limits differ: in NSW, 6 years for major defects and 2 years for other defects for contracts from 1 February 2012.
This guide is part of mistakes, disputes and official sources. It is general information, not legal advice.
The Australian Consumer Law guarantees
| Guarantee | What it means for a renovation | Example of a failure |
|---|---|---|
| Due care and skill | Work done with the skill of a competent tradesperson, taking reasonable care to avoid loss or damage | Tiles laid without proper falls, so water pools |
| Fit for a stated purpose | If you told the builder what you need the work to do, it must be fit for that purpose | You said the deck must take a spa; it sags under the spa |
| Reasonable time | If no completion date was agreed, the work must be done within a reasonable time | A small job left half-done for months |
| Products: acceptable quality | Appliances, tapware and fittings must be safe, durable and free from defects | A new oven that fails within weeks |
The ACL is a national law administered by the ACCC and state and territory consumer agencies. It applies to services and goods bought by a consumer, which includes services of a kind ordinarily acquired for personal, domestic or household use, so home renovation work for your own home will generally qualify.
Major and minor failures
If a service has a minor failure, the business can choose to fix it in a reasonable time. If the failure is major (for example, work that is unsafe or that a reasonable consumer would not have accepted had they known), you may be able to cancel the service and get a refund for the unused portion or compensation for the drop in value. You may also claim compensation for reasonably foreseeable loss caused by the failure.
State statutory warranties
State home building laws imply warranties into every contract for residential or domestic building work. They are broadly similar:
| Warranty (general wording) | NSW (Home Building Act 1989) | Victoria (Domestic Building Contracts Act 1995) | Queensland (QBCC Act, Schedule 1B) |
|---|---|---|---|
| Work done with due care and skill, in a proper and workmanlike manner | Yes | Yes | Yes |
| Materials good and suitable, new unless otherwise stated | Yes | Yes | Yes |
| Work complies with the law and the plans | Yes | Yes | Yes |
| Work completed with due diligence and within the time agreed or a reasonable time | Yes | Yes | Yes |
| Dwelling fit for occupation (where relevant) | Yes | Yes | Yes |
Who can rely on them: the owner who contracted, and in many cases later owners of the property.
Time limits
| State | Period (overview) | Where to confirm |
|---|---|---|
| NSW | 6 years for major defects, 2 years for other defects (contracts from 1 February 2012), with a further 6 months if the defect appears in the last 6 months | Building Commission NSW |
| Victoria | Building actions generally must start within 10 years of the occupancy permit or final inspection certificate | Building and Plumbing Commission; Building Act 1993 |
| Queensland | Statutory warranty periods for structural and non-structural defects set in Schedule 1B; home warranty claim periods differ | QBCC |
These limits interact with insurance claim periods, which are often shorter. Notify defects in writing as soon as you find them.
How to use your rights
- Write to the builder. Describe the defect, attach photos, refer to the contract and the warranty, and ask for rectification by a reasonable date.
- Keep records. Contract, variations, invoices, emails, photos of work in progress, inspection reports.
- Get an independent report for disputed or significant defects. It helps the regulator, insurer and tribunal.
- Contact the regulator. Building Commission NSW, the Building and Plumbing Commission in Victoria or the QBCC in Queensland offer dispute or complaint processes.
- Notify the insurer if the builder may not be able to fix it. See home warranty insurance by state.
- Apply to the tribunal if needed. See building disputes.
What these rights do not cover
- Defects caused by your own misuse or lack of maintenance.
- Work you did yourself as an owner-builder (although buyers may have rights against you).
- Cosmetic matters that are within accepted tolerances. NSW and other states publish guides to standards and tolerances that are often used to judge this.
- Delays you caused or agreed to.
Worked example (illustrative)
A shower leaks into the hallway 18 months after a NSW bathroom renovation. The cause is a failed waterproofing membrane. Water damage to the hallway floor is likely a defect in a major element (waterproofing) and may count as a major defect, which would give a 6-year period rather than 2. The owner writes to the builder within days, attaches photos and a plumber's leak test, and asks for rectification within 21 days. When the builder does not respond, the owner contacts Building Commission NSW and notifies the HBC insurer in case the builder cannot be pursued. The classification of the defect is a legal question; this example only shows the steps.
FAQ
Can a contract exclude these warranties?
No. State statutory warranties and ACL guarantees cannot be excluded by contract.
Do the warranties apply to small jobs?
The ACL guarantees apply whatever the price. State statutory warranties apply to the residential or domestic building work covered by each Act.
Can a later owner claim?
In many cases, yes, under the state statutory warranties and home warranty cover.
Who enforces the ACL?
The ACCC and state and territory consumer agencies, such as NSW Fair Trading and Consumer Affairs Victoria. For building disputes, the building regulator is usually the first port of call.
