How Defect Rectification Works in Western Australian Residential Building

What it is

Defect rectification in Western Australia runs through the Building Services (Complaint Resolution and Administration) Act 2011 (WA), administered by the Building and Energy division of the Department of Local Government, Industry Regulation and Safety. The Building Commissioner takes complaints, attempts conciliation and can issue a building remedy order requiring the builder to rectify defective work. The State Administrative Tribunal (SAT) sits above with a higher money cap.

The pathway is distinct from the section 11 HBCA make-good obligation, which is a private contract term the owner can enforce directly against the builder.

The section 11 make-good starting point

Section 11 of the Home Building Contracts Act 1991 (WA) implies a term that the builder is liable to make good defects notified in writing within 4 months of practical completion (extendable by contract). That is the direct contractual route: the owner notifies the builder, the builder attends, defects are rectified.

Most Western Australian defect claims never reach BSCRA because the section 11 make-good resolves them during the 4 month (or contractually extended) period. The BSCRA pathway is for the residue of claims where the builder disputes the defect, refuses to rectify or delays past the contractual period.

The BSCRA complaint

An owner lodges a written complaint with Building and Energy under section 5 of BSCRA. The complaint identifies the builder, the work and the defect. Building and Energy assigns an officer, reviews the material and typically arranges a site inspection where the defect is technical.

Section 12 preliminary requirements: the owner must have first attempted to resolve the matter directly with the builder, and the complaint must not be on foot in another court or tribunal proceeding.

The building remedy order

Where the complaint is substantiated, the Building Commissioner can make a building remedy order under Part 3 of BSCRA. The order specifies the defective work, the required rectification and the timeframe. Building Commissioner orders are capped at $100,000. Compliance is a licensing obligation for registered builders.

The building remedy order runs from practical completion up to 6 years, matching the statutory workmanship complaint window. HBCA contract complaints (breach of contract terms, section 4 or 5 non-compliance) run under a shorter 3 year window from completion.

Escalation to SAT

Where the amount exceeds the Commissioner's $100,000 cap, or where the parties dispute the Commissioner's finding, the matter escalates to the State Administrative Tribunal under section 31 of BSCRA. SAT can make building remedy orders up to $500,000 and has broader remedial powers.

SAT is also the forum for review of Building Commissioner decisions. A builder disputing a remedy order may seek SAT review within the prescribed timeframe.

Home Indemnity Insurance response

Home Indemnity Insurance under Part 3A of the HBCA and the Home Building Contracts Regulations 1992 (WA) responds to non-completion and defects up to $200,000. Cover triggers are the builder's death, disappearance, insolvency or registration cancelled or not renewed for financial reasons. The trigger analysis does not depend on whether the defect is structural.

Once HII responds, the certificate covers claims made within 6 years of practical completion. That matches the BSCRA workmanship window, giving owners a consistent 6 year horizon whether the claim runs against the builder or against the insurer.

What if the builder refuses to comply

Non-compliance with a Building Commissioner order or a SAT order triggers three consequences. The order is enforceable through the Magistrates Court. Building and Energy may take disciplinary action against the builder's registration. Where the builder becomes insolvent or has its registration cancelled, HII responds to the defect within the 6 year window.

How Western Australia compares

Western Australia's BSCRA-then-SAT pathway is closer to the QBCC direction-to-rectify-then-QCAT model in Queensland than to the tribunal-first structure in NSW (NCAT) or VIC (VCAT). The dual money cap ($100,000 Commissioner, $500,000 SAT) is unique in Australia and lets many claims resolve at the Commissioner level without a tribunal hearing.
