The certifier works together with project stakeholders to facilitate your building approval application with council (more info from QBCC) . Once approval is obtained, building work can begin.
The approval process concludes following the final inspection and collation of certificates at the completion of the build. Then homeowners can enjoy peace of mind, knowing their home is safe and compliant.
BA&A are private certifiers. We specialise in Class 1a and Class 10 building approvals in Brisbane (BCC) and surrounding regional councils. Find out about classes and building classification here
The chart below outlines the general steps and inspections through the building approval application.

The vailidity period of a residential / pool BA is one year (six months for demo permits).
BA&A works together with project stakeholders to support finalisation. Once building work is complete, the final inspection can be arranged and final documentation collated. If more time is required, an extension of time (EoT) may be available, these are usually quick and easy for the applicant / builder to arrange. Get in touch with the office to update your certifier.
