The Queensland Certification Experts


Growing from a family owned company, Building Approvals and Advice (BA&A) is committed to providing safer homes for South East Queensland. We specialise in the Brisbane region. Our role is to ensure that building work complies with all National Construction Code (NCC), Queensland Development Code (QDC) and Australian Standards (AS).

As industry experts, we prioritise working with industry professionals such as:  

  • Building designers 

  • Builders 

  • Architects 

  • Engineers 

  • Town Planners 


Due to the complexity of the NCC, we don't have the capacity to take on Owner Builder projects or certify pre existing work. 


Awarded Building Certification Team of the Year 2016, 2017, 2018 and 2019 by the Royal Institute of Chartered Surveyors (RICS), our team is passionate about being part of the construction industry and keeping our clients up to date with its constant changes by:

  • Being involved in industry events (e.g. Brisbane Pool Spa & Outdoor Living Expo) 

  • Organising CPD events and workshops quarterly 

  • Being members of industry associations (DAIA, Timber Queensland) 

Certification process

The approvals process can be pretty complicated, so we've simplified it below. Not every approval will follow this process exactly, but it should apply to 90% of projects.
