Residential building defect claim workflow
NSW now runs a multi-track regime — statutory warranties for six years (major defects) or two years (other defects), a statutory duty of care under DBP Act s 37 reaching back to 2010, and owners corporation claims for class 2 buildings. Choosing the correct track, within time, is the core of the workflow.
This is an 8-step workflow for a residential building defect claim under the Home Building Act 1989 (NSW), the statutory warranties, and the duty of care under the Design and Building Practitioners Act 2020 (NSW). It runs from defect identification through expert reports, pre-action notices, and NCAT or Supreme Court claim.
Before you start
- Signed costs agreement and conflict check
- Building contract, plans, and certificates
- Strata roll or title details
- Photographs and records of the alleged defects
The workflow
Identify defects and commission expert report
Commission a suitably qualified building consultant to inspect and report, categorising each defect as major or other, with a Scott Schedule format showing location, cause, and rectification method.
Identify the right defendants and time limits
Identify the builder, head contractor, design practitioners, and certifier. Map time limits: 6 years for major defects, 2 years for other defects under s 18E, 10 years from completion for DBP Act duty of care.
Issue rectification notice
Issue a rectification notice under s 18BA, offering the builder a reasonable opportunity to rectify. Record refusal, partial rectification, or poor-quality re-works.
Consider Fair Trading complaint and conciliation
Lodge a complaint with NSW Fair Trading for defect conciliation and a rectification order where the builder is cooperative and the scope is limited.
Prepare NCAT application (under $500k)
For claims under the NCAT jurisdictional limit, prepare a Home Building application in the Consumer and Commercial Division, attaching the Scott Schedule expert report.
Prepare Supreme Court or District Court proceedings (over NCAT limit)
For larger claims, prepare Supreme Court or District Court proceedings, pleading statutory warranty breach and DBP Act s 37 duty of care in the alternative.
Manage Home Building Compensation Fund claim
Where the builder has died, disappeared, become insolvent, or had their licence suspended for failing to comply with a money order, lodge a claim on the Home Building Compensation Fund.
Settle or run to hearing and implement
Attend NCAT conciliation or court mediation, settle on a work order or money order, or run to hearing. Implement the rectification works or payment.
What you will have at the end
Either a negotiated rectification (works or money), an NCAT work order, or a court judgment for damages, with access to the HBCF where the builder is not available to pay.
Common issues
- Wrong track chosen — statutory warranty vs DBP Act duty
- Expert report not in Scott Schedule format
- Rectification notice missed, limiting remedies
- Class 2 building owners corporation claim run by a single lot owner
- Time limit run from wrong date of completion
