Do private certifiers have to respond to complaints in Sydney?

Yes, private certifiers in Sydney are legally required to respond to complaints regarding building work they supervise. Under NSW legislation, certifiers must investigate written complaints about non-compliant building work, issue required directions to builders, and maintain professional conduct standards overseen by NSW Fair Trading and the Building Commission NSW.

When undertaking construction in New South Wales, property owners often engage a private certifier to issue a Complying Development Certificates (CDC) or a Construction Certificate. While the certifier acts as a public official, they are also a service provider. If you are searching for a private certifier near me in Sydney, it is vital to understand the regulatory framework that governs their accountability to the public and the property owner.

The Legal Obligation to Address Complaints

In Sydney and across NSW, the role of a Registered Certifier is governed by the Building and Development Certifiers Act 2018. Certifiers do not have a choice in whether they acknowledge a valid complaint regarding a breach of building standards or a failure in their administrative duties. They serve a critical function in ensuring the National Construction Code (NCC) and Australian Standards are met.

If a neighbour or an owner submits a written complaint about a development, the certifier is mandated to take specific steps. They must determine if the building work is inconsistent with the approved plans or if there is a threat to health and safety. While they are not "site supervisors" in the same way a builder is, they are responsible for the regulatory oversight of the project.

For example, if you are working with a private certifier in Mona Vale within the Northern Beaches Council area, they must ensure that any complaint regarding environmental protections or structural deviations is handled according to the statutory requirements of the NSW planning system.

Types of Complaints and Required Actions

It is important to distinguish between different types of complaints, as the certifier's response will vary depending on the nature of the issue:

• Complaints about Building Work: If a certifier becomes aware of a significant non-compliance, they must issue a "Written Direction to Comply." This is a formal notice to the builder to fix the issue. If the builder fails to comply, the certifier must notify the local council or the Department of Planning.
• Complaints about Certifier Conduct: If the complaint is about the certifier's own professional behaviour—such as failing to carry out a mandatory inspection or issuing an Occupation Certificate NSW prematurely—the matter is typically handled by NSW Fair Trading.
• Administrative Delays: While certifiers are expected to be efficient, "responsiveness" in a legal sense usually refers to their duty to act on non-compliance rather than how quickly they reply to general emails.

Projects located in areas like Campbelltown City Council, served by a private certifier in Minto, must adhere to the same stringent reporting lines. Failure by a certifier to respond to a documented breach can lead to disciplinary action, fines, or the suspension of their registration.

The Process: How to Lodge a Complaint Correctly

1. Initial Contact: Attempt to resolve the issue directly with the certifier in writing. Clearly state the address, the approval number, and the specific section of the NCC or the approved plans that you believe is being breached.
2. Formal Notice: If the certifier does not respond, or their response is inadequate, you can escalate the matter. Ensure you have evidence, such as photos or reports from a qualified engineer or building consultant.
3. NSW Fair Trading: The Building Commission NSW and NSW Fair Trading are the bodies responsible for investigating the professional conduct of certifiers. They can audit files and penalise certifiers who fail to uphold their statutory obligations.

Frequently asked questions

What should I do if my private certifier is not responding to my emails?

If a certifier is unresponsive, first ensure your communication is formal and references your specific project number. If the silence persists regarding a safety or compliance issue, you should contact the Building Commission NSW or NSW Fair Trading to lodge a formal complaint about their professional conduct.

Can a private certifier ignore a neighbour's complaint about a boundary issue?

Certifiers must investigate complaints related to the building approval and the NCC. However, many boundary disputes are civil matters or matters for the local council. If the complaint relates to the building's physical location being different from the approved plans, the certifier is required to respond and investigate.

Is there a specific timeframe for a certifier to respond to a complaint?

While the law doesn't specify a "number of days" for a general reply, it requires "prompt action" on safety or non-compliance issues. For formal Written Directions, the certifier must notify the council within set periods if the builder fails to rectify the reported problem.

Can a certifier lose their license for ignoring complaints?

Yes, persistent failure to act on valid complaints or to perform statutory duties is a ground for disciplinary action. This can range from formal cautions and fines to the permanent cancellation of their registration to practice in NSW.
