How Are Defective Building Works Legally Resolved in Perth?

Building a new home or renovating an existing property is a major investment. Homeowners expect the finished work to be safe, strong and completed according to the agreed plans and building standards. However, problems can arise when builders fail to meet their responsibilities. Cracked walls, leaking roofs, uneven floors, poor waterproofing and unfinished work are common examples of building defects.

When these problems are not fixed by the builder, they can lead to financial losses, stress and legal disagreements. Fortunately, homeowners in Western Australia have legal options to address these issues.

Understanding how building disputes are handled can help you protect your property and make informed decisions. This guide explains how building contract dispute lawyers Perth can help homeowners resolve defective building work and understand their legal rights.

What Are Defective Building Works?

Defective building works refer to construction or renovation work that does not meet the agreed requirements, acceptable workmanship standards or relevant building regulations.

Some defects are easy to notice, while others may remain hidden until months or even years after construction.

Common examples include:

Structural defects: Cracks in walls, damaged foundations, roof problems or unstable structures.

Waterproofing issues: Water leaking through bathrooms, balconies, roofs or external walls.

Poor workmanship: Uneven flooring, badly installed tiles, damaged finishes or incorrectly fitted doors and windows.

Plumbing and electrical problems: Faulty installations, water leaks and unsafe electrical work.

Incomplete construction: Work that has not been completed according to the building contract.

Non-compliant construction: Work that does not meet applicable building codes, approved plans or relevant standards.

These problems can affect your property's value, safety and long-term condition.

What Does Western Australian Law Say About Building Defects?

In Western Australia, building disputes are mainly governed by legislation such as the Building Services (Complaint Resolution and Administration) Act 2011 and the Home Building Contracts Act 1991.

These laws provide a framework for dealing with defective workmanship, contractual disagreements and disputes between homeowners and builders.

Under the Home Building Contracts Act, builders generally have an obligation to fix defects reported in writing within four months after practical completion, at their own cost. A contract may provide a longer notification period.

However, this does not mean homeowners automatically lose every legal option after four months. Building service complaints can generally be lodged with Building and Energy within six years of completion, subject to the applicable requirements. Contract-related complaints may have a separate three-year time limit.

The correct deadline depends on the nature of the complaint, so obtaining legal advice early is important.

How Are Building Defect Disputes Legally Resolved in Perth?

If your builder refuses to fix defective work or disagrees with your complaint, several steps may help resolve the matter.

1. Identify and Document the Defects

The first step is to identify the problems and collect supporting evidence.

Homeowners should:

Take clear photographs and videos of the defects.

Keep copies of the building contract and approved plans.

Save invoices, payment receipts and variation agreements.

Record conversations and emails with the builder.

Obtain an independent building inspection report where necessary.

A professional building inspection can help explain the nature of the defects, their possible causes and the estimated repair costs.

Good documentation makes it easier to explain your concerns and support your legal position.

2. Contact the Builder in Writing

Before starting formal legal proceedings, homeowners should usually give the builder an opportunity to address the problem.

Prepare a written notice explaining the defects, where they are located and what repairs you are requesting.

Include photographs or inspection reports where available. Keep a copy of everything you send.

If the builder agrees to repair the work, make sure the proposed repair arrangements and completion dates are confirmed in writing.

If the builder ignores your request or refuses to take responsibility, you may need to consider formal dispute resolution.

3. Lodge a Complaint with Building and Energy WA

Building and Energy, part of the Western Australian Government, provides a dispute resolution service for eligible building complaints.

Homeowners can lodge complaints about defective workmanship, unsatisfactory building services and certain breaches of home building contracts.

Depending on the circumstances, the Building Commissioner may:

Encourage both parties to reach an agreement.

Arrange conciliation to discuss possible solutions.

Issue a building remedy order requiring repairs or payment.

Refer complex or unresolved matters to the State Administrative Tribunal (SAT).

A building remedy order may require the builder to fix defective work, pay reasonable rectification costs or provide compensation.

This process can provide an alternative to immediately starting court proceedings.

4. Take the Matter to the State Administrative Tribunal

If a building dispute cannot be resolved through the initial process, the matter may be referred to the State Administrative Tribunal.

The SAT can review certain Building Commissioner decisions and determine referred building disputes.

Both parties may need to provide supporting documents, expert reports, photographs and other evidence.

The tribunal considers the information presented and makes decisions according to the applicable law.

It is important to understand that strict procedural and application deadlines may apply. For example, applications to review certain Building Commissioner decisions generally need to be made within 28 days.

5. Consider Court Proceedings

In some situations, court action may be necessary, particularly when a dispute falls outside the Building Commissioner's jurisdiction or involves a claim that cannot be resolved through the available administrative process.

Depending on the amount and nature of the claim, the Magistrates Court or District Court may be appropriate.

A lawyer can assess your circumstances, explain the available legal options and help determine the most suitable approach.
