What is a building certification?

In Queensland, it is a legal requirement to assess buildings and structures against the Building Assessment Regulations.
These provisions include:

  • The Australian Building Code (Volumes 1 and 2 of the National Building Code).
  • Queensland Development Code.
  • Various other Queensland regulations.

Obtaining a building certification from a private certifier confirms that your building is compliant with local and state regulations. This also applies to future developments or subdivisions.

A1 Certifiers, the professional private building certifier Qld, offers the highest level of service. Our experienced construction industry professionals can certify your project through all construction phases to ensure a smooth process.

Unmatched customer service! We were late to submit our request for building approval which was going to cause major disruption to everyone involved in our pool installation. A1 showed utmost professionalism and understanding of our situation and pulled out all stops to get our assessment done in the fastest time possible! We can’t thank you enough.

A1 certifier has helped my carport certification installed in 2013 recently. A1 take the initiation to connect the council and resolve the issue within few hrs. You can not ask for more like A1 in such professional, efficient and stress free results. Like their brand it is A1 service.
I very recently used the services of A1 Certifier to help me navigate the [at times] difficult world of local government approvals. Michael and his team were excellent to deal with, very knowledgeable - providing guidance at every step and got the desired result without issue. I absolutely recommend the service that Michael and his team provide and will utilize their service again.

We can also assist with the following:



Building permits require an assessment against the Australian Building Code (Volume 1 and 2 of the National Building Code) and the Queensland Building and Plumbing Codes. These guidelines and regulations address, among other things, whether the building is soundly designed and constructed and safe to live in.

City Council approval may necessary to ensure the public’s safety and the environment. For example, a large deck can cause soil erosion or encroach on the land. Therefore, council approval is needed to build a deck over a certain size in most local council areas in Qld.

We are one of the most affordable building certifiers in Queensland. Prices vary depending on the type and scope of project work and the different submission fees that are required.
