What is the role of a private certifier in QLD?

In Queensland, a private certifier plays a crucial role in the building and construction industry. The primary function of a private certifier is to ensure that building works comply with the Building Act 1975, the Building Code of Australia (BCA), and other relevant standards and legislation. Their role encompasses a wide range of responsibilities, aimed at safeguarding the integrity, safety, and compliance of construction projects. Here are some of the key responsibilities and roles of a private certifier in QLD:

1. Assessing and Approving Building Applications

Private certifiers assess building plans and specifications against the BCA and relevant Queensland legislation to ensure compliance. If the plans meet all requirements, the certifier can approve the building application, allowing the project to proceed.

2. Conducting Inspections

Throughout the construction process, private certifiers are responsible for conducting various mandatory inspections to ensure the work complies with the approved plans and building codes. These inspections can include, but are not limited to, footings, slab, framing, and final inspections. Note that some of these inspections can also be carried out by engineers, for example: footings and frame inspections.

3. Issuing Certificates

Upon satisfactory inspection and completion of different stages of construction, private certifiers issue relevant certificates. For example, they provide a Form 16 (Inspection Certificate) for various stages of building work and a Form 21 (Final Inspection Certificate) upon the successful completion of the construction project, signifying compliance with the approved plans and building codes.

4. Consulting and Advising

Private certifiers also play an advisory role, providing guidance to builders, architects, engineers, and homeowners about building regulations and how to achieve compliance. They may offer solutions or alternatives to help address compliance issues that arise during the design or construction phases.

5. Record Keeping

Certifiers must maintain comprehensive records of all approved documentation, inspection results, and correspondence related to the building project. These records serve as an official account of the project’s compliance with building standards and regulations.

6. Ensuring Safety and Accessibility

An essential aspect of their role is to ensure that buildings are safe for occupancy and accessible, in accordance with the BCA and Australian Standards. This includes assessing fire safety installations, access paths, and other safety measures.

7. Handling Disputes and Non-compliance Issues

When building work does not comply with the approved plans or regulations, private certifiers are responsible for notifying the builder or owner and providing them with the opportunity to rectify the issue. They can issue enforcement notices to ensure compliance is achieved.


The role of a private certifier in Queensland is integral to maintaining the safety, quality, and compliance of building works. By ensuring that construction projects adhere to the Building Act, the BCA, and other relevant standards, private certifiers protect the interests of homeowners, occupants, and the general public, contributing to the overall integrity of the built environment.
